General Information 
Ridomil is a systemic fungicide for use on selected crops to 
control certain diseases caused by members of the Oomycete class 
of fungi. Other fungicides must be used to control diseases 
incited by other classes of fungi. 
THIS PRODUCT IS NOT TO BE USED IN FOLIAR APPLICATIONS UNLESS 
SPECIFIED ON THIS LABEL OR IN SOLUTIONS USED TO DIP PLANTS. DO 
NOT USE IN NURSERIES, TURF, OR LANDSCAPE PLANTINGS UNLESS SPECI­
FIED IN THIS LABEL. 
~: Ridomil is a systemic fungicide having a specific 
mode of action and could be subject to development of 
insensitive strains of fungi. Development of insensitivity 
cannot be predicted. Therefore, Ciba-Geigy 
cannot assume liability for crop damage resulting from 
insensitive strains of fungi. If treatment is not 
effective following the use of Ridomil as -ecommended, an 
insensitive strain of fungi may be present. If the treat­
ment is ineffective due to the presence of a Ridomil insen­
sitive strain of fungi, neither Ridomil nor any other fun­
gicide with similar action will effectively control that 
disease. Consideration should then be given to the prompt 
use of other types of suitable fungicides. Consult with 
your State Agricultural Experiment Station or Extension 
Service Specialist for guidance on your particular crop and 
disease control situation. Do not use Ridomil 2E for dis­
ease control in crops grown in greenhouses, lath houses, 
hydroponics, float houses, or in bedding plant struct~res. 
Do not make foliar applications to field grown tobacco, or 
other crops unless specified since this practice may 
encourage more rapid development of insenSitivity. 
Where rate ranges are specified on this label, use the higher 
rate when heavy disease pressure is expected and the lower rate 
when disease pressure is expected to be light unless otherw~~~' 
noted. 
. . 
To avoid spray drift, do not apply under windy condi~ioris. 
Avoid spray overlap, as crop injury may result. . 
Mixing Instructions 
Add one-fourth to one-half of the required amount of· \:.:l':er to 
the spray tank, add the proper amount of Ridomil 2E, then a~d ..

the rest of the water. When tank mixing other products with 
Ridomil 2E, follow the proper sequence of adding products to the 
spray tank. Wettable powders or water dispersible granules 
should be added to the WJter in the tank first, followed by 
flowable products, with emulsifiable concentrates, such as 
Ridomil 2E, added last. Provide sufficient agitation during 
mixing and application to maintain a uniform emulsion. 
Ridomil 2E is usually compatible with Balan®, Bravo®, Dasanit~ + 
Di-Syston®, Dithane® M-22, Dithane M-45, Dasanit + Nemacur®, 
Dasanit, D,z'n®, Enide®, Furadan®, Lorsban®, Manzate®, Man-
zate 200 Mocap®, Mocap Plus 4-2EC, Paarlan®, Terraclor® 2E, 
Terraclc~' 75W, and Tillam®. 
To assure the compatibility of Ridomil 2E with these and other 
products, pour the products into a small container of water in 
the correct proportions. After thorough mixing, let stand fer 
five minutes. If the combination remains mixed, or can be 
remixed readily, the mixture is compatible. 
: .. - .-
For banded applications, the area actually is the area covered 
by the band, not total cropland area planted. Some row-crop 
recommendations are based on treating in-the-row and these rates 
generally are specified as amounts (fl. oz.) of product per cer­
tain row length (0ften 1,000 ft.). Others express rates as 
amount per treated acre which means the total area treated with 
the pesticide. If rates are expressed as amount per treated 
acre and banded applications are used, the amount of pesticide 
used per acre will be proportionately less. The following for­
mula can be used to calculate the amount of Ridomil 2E needed 
per acre of crop when banded applications are made. 
Calculate the amount of Ridomil 2E needed for band treatment by 
the formula: 
broadcast rate amount needed band width in inches 
row spacing in inches X per acre = per acre of field 
~plication Instructions 
Apply Ridomil 2E by ground or air in sufficient water or liquid 
fertilizer to provide uniform coverage of the soil surface. 
Apply in a minimum of 20 gals/.A for ground applications and 
5 gals./A by air. Refer to the specific crop directions for use 
for application recommendations. 
BEFORE TANK MIXING RIDOMIL 2E WITH OTHER REGISTERED PRODUCTS FOi 
ANY USE ON THIS LABEL. READ THE LABEL OF THE TANK MIX PARTNER TO 
BE CERTAIN IT IS LABELED FOR USE ON THE PARTICULAR CROP AND THAT 
USE PATTERNS ARE COMPATIBLE WITH THOSE OF RIDQMIL 2E.

Application Through Irrigation System~ 
Ridomil 2E, alone or in combination with other pesticides which 
a~e registered for application through irrigation systems, may 
be applied through irrigation systems. Apply this product only 
through center pivot, solid set, hand move, moving wheel, 
micro-sprinkler or drip irrigation systems. DQ not apply this 
product through any other type of irrigation system. Crop 
injury, lack of effectiveness, or illegal pesticide residues in 
the crop can result from non-uniform distribution of treated 
water. If you have questions about calib~ation, you should con­
tact State Extension Service specialists, equipment manufactur­
ers or other experts. Do not connect an irrigation system 
(including greenhouse systems) used for pesticide application to 
a public water system unless the pesticide label-prescribed 
safety devices for public water systems are in place. A person 
knowledgedble of the chemig~tion system and responsible for its 
operation, or under the supervision of the responsible person, 
shall shut the system down and make necessary adjustments should 
the need arise. 
Operating Instructions 
1. The system must contain a functional check valve, vacuum 
relief valve, and low pressure drain appropriately located 
on the irrigation pipeline to prevent water-source 
ccntamination from backflow. 
2. The pesticide injection pipeline must contain a func­
tional, automatic, quick-closing check valve to prevent 
the flow of fluid back toward the injection pump. 
3. The pesticide injection pipeline must also contain a func­
tional, normally closed, solenoid-operated valve located 
on the intake side of the injection pump and connec~.ed to 
the system interlock to prevent fluid from being withdrawn 
from the supply tank when the irrigation system is either 
automatically or manually shut down. 
4. The system must contain functional interlocking controls 
to automatically shut off the pesticide injection pump 
when the water pump motor stops. 
5. The irrigation line or water pump must includa a func­
tional pressure switch which will stop the water pump 
motor when the water pressure decreases to the point where 
pesticide distribution is adversely affected. 
6. Systems must use a metering pump, such as ~ positive dis­
placement injection pump (e.g., diaphragm pump) effec­
tively designed and constructed of materials that are com­
patible with pesticides and capable of being fitted with a 
system interlock.

7. Do not apply when wind speed favors drift beyond the area 
intended. 
Application Instructions 
( 
Ridomil 2E must be applied on the schedule specified in the spe­
cific crop use recommendations, not according to the irrigation 
schedule. 
With the exception of avocados and citrus, Ridomil 2E has not 
been sufficiently tested when applied through irrigation systems 
to assure consistent product performance for all labeled uses. 
The following calibration and application techniques are pro­
vided for user reference, but do not consitute a warranty of 
fitness for application through sprinkler or drip irrigation 
equipme~. Users must check with state and local regulatory 
agencies for potential use restrictions before applying any 
agricultural chemical through sprinkler or drip irrigation 
equipment. 
Note: Do not inject Ridomil 2E at full strength or deteriora­
tion of valves and seals may occur. Use a dilution ratio of at 
least 10 parts water to 1 part Ridomil 2E. Ridomil 2E is corro­
sive to many seal materials. Leather seals are best. EPDM or 
silicone rubber seals can be used, but should be replaced once a 
year. Do not use Viton, Buna-N, Neoprene or PvC seals. 
Center Pivot Irrigation Equipment (Use only with drive systems 
which provide uniform water distribution) 
Determine the size of the area to be treated. 
Determine the time required to apply 1/2 - 1 inch of water 
over the area to be treated when tne system and injection 
equipment are operated at normal pressures recommended by 
the equipment manufacturer. Run the system at 80-95% of the 
manufacturer's rated capacity. 
Using water, determine the injection pump output when oper­
ated at normal line pressure. 
Determine the amount of Ridomi1 2E required to treat the 
area covered by the irrigation system. 
Add the required amount of Ridomil 2E and sufficient water 
to meet the injection time requirements to the solution 
tank. 
Maintain constant solution tank agitation during the injec­
tion period. 
Continue to operate the system nntil the Ridomil 2E solution

has cleared the sprinkler head. 
Solid Set~Hand Move and Moving Wheel Irrigation Equipment 
~etermi~e the acreage covered by the sprinklers. 
Fill injector solution tank with water and adjust flow rate 
to use the contents over a 20 to 30-minute interval. 
Determine the amount of Ridomil 2E required to treat the 
area covered by the irrigati~n system. 
Add the required amount of Ridomil 2E into the same quantity 
of water used to calibrate the injection period. 
Operate the system at the same pressure and time interval 
established during the calibration. 
Inject Ridomil 2E at the end of the irrigation cycle in 
1/2 - I inch of water or as a separate application to maxi­
mize the effectiveness of the fungicide. 
Stop injection equipment after treatment is completed. Con­
tinue to operate the system until the Ridomil 2E solution 
has cleared the last sprinkler head. 
Micro Sprinkler or Drip Irrigation Systems 
General Instructio~ 
Each run of the irrigation system must be calibrated sepa­
rately to determine the time it takes water to move through 
the system and to make sure all emitters in the system are 
putting out the same amount of water. 
Only pressure injection or venturi equipment is recommended. 
Determine the area to be treated in each irrigation run. 
Measure the output of each of the emitters or drip tubes 
closest to and farthest from the injector site. 
For calibration, substitute a concentrated detergent (such 
as Wisk) or a soluble fertilizer for the Ridomil 2E in the 
injector tank. The detergent will bubble as it leaves the 
emitters. The time period over which bubbles occur should 
be checked for both the closest and farthest emitters. If 
these times are not within 2 minutes of each other, adjust 
the dilution ratio and/or the injection rate. 
If a soluble fertilizer is used, measure the time intervals 
with a salt bridge. If a drip system is being calibrated, 
substitute soluble fertilizer for the Ridomil 2E in the 
injector and measure the time intervals with a salt bridge.

-9-
Step-b¥-Step Instructions 
Before starting to calibrate, operate the system until all 
the emitters are putting out at equal flow rates or until 
the system is operating at full pressure. 
Make up an indicator solution of detergent or fertilizer, 
using the same ratio to be used when mixing Ridomil 2E. 
Set the injector to apply the indicator solution at the 
injection rate to be used in the actual Ridomil 2E applica­
tion. 
Attach a 5-inch length of flexible tubing over th!~ emitter 
closest to the injection point, another length OVE!r the 
emitter farthest away. Both emitters should be mc·nitored to 
determine the time intervals that the indicator solutions 
are observed. 
Begin injecting the indicator solution. Direct the flow 
from the tubes at the emitters into a small container. 
Begin timing when the indicator solution is first detected, 
stop timing when the indicator solutions are no longer 
detected. 
If the period of detection of the indicator solution between 
the two emitters are within two minutes of each other, com­
parable coverage will be obtained. If they are not, make 
adjustments by increasing the dilution ratio, using more 
water per part of Ridomil 2~, or adjust the injector to a 
slower flow rate. 
Once the system is calibrated, dilute the needed amount of 
Ridomil 2E with water using a minimum of 10 parts water to 
1 part Ridomil 2E. 
Do not begin to inject Ridomil 2E into the system until all 
emitters are producing equal flow rates, or until the system 
is at full pressure. 
Inject the Ridomil 2E into the system at the end of the 
irrigation set in 1/2 - 1 inch of irrigation water. 
Alfalfa* 
*Including birdsfoot trefoil 
Ridomil 2E applied to the soil at planting will provide contr~l 
of damping-off caused by P¥thium spp. and root rots caused by 
Ph¥tophthora spp.

-10-
Stand Establishment 
Apply 1 to 2 ptS./A as a broadcast surface spray at planting in 
a minimum of 20 gals. of water or following impregnation on fer­
tilizer. 
If alfalfa seed was previously treattd with metalaxyl as a seed 
dressing, an application of Ridomil 2E at I pt./A is recommended 
at planting. Use the higher rate (2 ptS./A) in areas where 
disease pressure is expected to be heavy. 
Note: To avoid possible illegal re~idues, do not feed green 
forage or cut hay for 60 days following application. 
Apples (Bearing and Nonbearing Trees) 
Use of Ridomil 2E will aid in the control of crown, collar and 
root rot caused by Phytophthora spp. when used in conjunction 
with good cultural practices and rootstocks that are most toler­
ant to the disease. Ridomil 2E applications should be made 
before symptoms appear, especially in areas of the orchard 
favorable for disease development. Ridomil 2E will not 
revitalize trees showing moderate to severe disease symptoms. 
Broadcast Spray or Banded Applications: Apply 2 gals./treated 
acre as a broadcast spray (6 fl. oz./l,OOO sq. ft.) in suffi­
cient water ';0 obtain thorough coverage. The treated area is 
based on the area under the tree canopy or the area of the 
sprayed row. Soil surface sprays of Ridomil 2E will not be 
effective until the fungicide is moved into the root zone by 
rainfall or irrigation. Applications should be made in early 
spring before growth starts and in the fall after harvest but 
before the ground freezes. 
Dren~: Mix 1 qt. of Ridomil 2E with 100 gals. of water. Apply 
the amount of diluted mixture indicated in the table below 
around the trunk of each tree. Applications should be made in 
early spring before growth starts and in the fall after harvest 
but before the ground freezes. On new plantings, delay the 
first application until two weeks after planting. 
Note: To determine trunk diameter, measure the trunk 12 inches 
above the soil line.

Note~: (1) Do not dip roots of trees in or spray bare roots 
with solutions containing Ridomil 2E. (2) Do not graze or feed 
cover crops in treated orchards, or illegal residues may occur. 
Asparagus 
Ridomil 2E will control crown rot and spear rot caused by 
Phytophthora spp. 
Apply 2 qts./A as a broadcast spray in a minimum of 10 gals. of 
water over the beds. 
Cutting Beds: Apply 30 to 60 days before the first cutting. 
For additional control, make another application just ~efore the 
beginning of harvest. 
New Plantings: Apply after planting seedlings or after covering 
one-year old crowns. 
Note: Do not apply Ridomil 2E within 1 day of harvest or poss~­
ble illegal residues may result. 
Avocados 
Root Rot - Phytophtho~a cinnamomi 
Begin applications at the start of the growing season or at 
transplanting. Two additional applicf.tions should be made at 
three-month intervals. Applications are not needed during the 
winter months of November through February. Ridomil 2E may be 
applied as a sleeve drench at the time of transplanting, as a 
soil surface spray under sprinkler irrigation systems, as a 
directed spray under drip emitters or injected into the irriga­
tion water. 
Sleeve Drench: Mix 1 fl. oz. of Ridomil 2E with 18 gals. of 
water. At the time of transplanting, drench the roots inside 
the sleeve with 1 qt. of Ridomil solution per tree. 
Note: The sleeve drench will not replace the soil surface 
applications for long term control of root rot. 
Sprinkler Irrigation: Apply as a soil surface spray under the 
canopy of the tree in sufficient water to obtain uniform cover­
age. See the following table for the amount of Ridomil 2E to 
use based on the diameter of the tree canopy. Start applica­
tions at the beginning of the growing season or at transplanting 
and continue at three-month intervals. 
Drip Irrigation: Apply the recommended amount of Ridomil 2E 
(see table) to the soil directly under the drip emitter at each

-12-
tree. If there is more than one emitter per tree, distribute 
the total amount of Ridomil 2E needed among the emitters. 
Injection into Ir):,igation Water (Sprinkler or Drip Irrigation 
Only): Inject Ridomil 2E into the irrigation water at a rate of 
2-4 fl. oz./l,OOO gals. (3 3/4-7 1/2 ppm active ingredient) at 
each irrigation. If Ridomil 2E is not applied at each irriga­
tion, use the table below to determine how much Ridomil 2E 
should be injected into the irrigation water. If Ridomil is to 
be used more frequently than every three months, adjust the 
rates so that no more than the specified amount is applied dur­
ing each three-month period. See the General Information sec­
tion of this label for further instructions and precautions when 
making applications through irrigation systems.

Notes: (1) For best results, use Ridomil 2E as soon as soil 
tests indicate the presence of Phytcphthora. (2) For new plant­
ings, the use of Phytophthora resistant rootstocks with Ridomil 
2E is recommended. Mature trees in moderate to advanced stages 
of decline cannot be cured with Ridomil 2E. (3) Do not apply 
more than 6 gals./A of Ridomil 2E/year. (4) Do not make an 
application within 28 days of harvest, or possible illegal 
residues may result. 
Berries 
Blueberries 
Use of Ridomil 2E will aid in the control of root rot caused by 
Phytophthora ~. when used in conjunction with good cultural 
practices to minimize disease problems. Ridomil 2E will not 
revitalize plants showing moderate to severe root rot symptoms. 
Established Plantings: Apply 1 pt./1000 linear ft. of row (14.5 
pts./A broadcast basis) in a three foot band over the row before 
the plants start growth in the spring. One additional applica­
tion may be made to coincide with periods most favorable for 
root rot development. 
New Plantings: 
after the time 
should be made 
Apply 2 gals./A broadcast to the soil at or 
of planting. One or two additional applications 
at 2-3 month intervals or to coincide with peri-

-13-
ods most favorable for root rot development. For banded appli­
cations, an l8-inch band over the row is recommended. Use the 
formula in the General Information section of the labe} to cal­
culate the amount needed per acre. 
Note: On new plantings, do not apply more than 3.6 gals./A 
broadcast during the 12 months before bearing harvestable fruit, 
or possible illegal residues may result. 
Cranberries 
Use Ridomil 2E as a soil application for control of Phytopthora 
root rot of cranberries caused by Phytophthora spp. 
Apply Ridomil 2E at 4-7 pts./A as a broadcast soil application 
for control of Phytophthora root rot of cranberries. Three 
applications per crop season are recommended. Make the first 
application in the fall after harvest. Make the second applica­
tion in the spring followed by a third application up to but no 
latsr than 45 days before harvest. 
Apply Ridomil 2E using ground or chemigation equipment. Suffi­
cient water should be used to allcw movement of Ridomil 2E into 
the root zone. Use a minimum of 20 gals. of water per acre when 
applying by ground equipment. Refer to the Application Through 
Irrigation Systems section of the label for instructions and 
precautions when making applications through irrigation systems. 
Notes: 1) Do not apply Ridomil 2E to cranberries by air. 2) To 
avoid possible illegal residues, do not apply within 45 days 
before harvest and do not apply more than 21 pts./A per growing 
season. 
Raspberries 
Ridomil 2E is a soil-applied systemic fungicide for use in the 
control of Phytophthora root rot. 
Apply 1 pt./1,OOO linear ft. of row to the soil surface in a 
three-foot band over the row. Make 1 application in the spring 
and another in the fall after harvest. Use the formula in the 
General Information section of this label to calculate the 
amount of Ridomil 2E needed per acre. 
Note: Do not apply Ridomil 2E within 45 days before harvest or 
possible illegal residues may result. 
Strawberries 
Ridomil provides control of red stele (Phytophthora fragariae),

-14-
vascular co~lapse (~. cactorum) and leather rot (~. cactorum) 
when used as directed. Applications may be made using ground 
application equipment or through drip irrigation systems. 
New Plantings: Apply Ridomil 2E at 2 qts./treated acre in 
sufficient water to move the fungicide into th~ root zone of the 
plants. Make one application after transplanting followed by an 
additional application 30 days before the beginning of harvest 
or at fruit set. A third application may be made during the 
harvest season, depending on environmental conditions and dis­
ease pressure. For banded applications, use the formula in the 
General InfOrmation section of this label to determine the 
amount of Ridomil 2E needed per acre. When applying Ridomil 2E 
through drip irrigation systems, use the same amount as would 
be applied in a banded application to cover the root zone of the 
plants. Observe the precautions concerning application of Rido­
mil through irrigation systems in the General Information sec­
tion of this label. 
Established Plantings: Apply Ridomil 2E at 2 qts.!treated acre 
in sufficient water to move the fungicide into ':.he root zone of 
the plants. Make one application in the spring after the ground 
thaws and before first bloom. A second application may be 
applied after harvest in the fall. For supplemental control of 
leather rot, an application may be made during the growing sea­
son at fruit set. For banded applications, use the formula in 
the General Information section of t~is label to determine the 
amount of Ridomil 2E needed per acre. When applying Ridomil 2E 
through drip irrigation systems, use the same amount as would be 
applied in a banded application to cover the root zone of the 
plants. Observe the precautions concerning application of Rido­
mil through drip irrigation systems in the General Information 
section of this label. 
Notes: (1) To avoid possible illegal residues, do not use more 
tl.an a total of 6 qts. of Ridomil 2E/treated acre/year. (2) For 
low annual rainfall areas, a surface application of Ridomil 2E 
needs to be moved into the root zone by rainfall, overhead irri­
gation, or mechanical incorporation. 
Citrus 
Includes grapefruits, lemons, limes, oranges, tangelos, Langer­
ines, citrus citron, kumquats and hybrids of these. 
Use Ridomil 2E on citrus for control of citrus foot rot, root 
rot, and trunk cankers caused by PhytQphthora spp. Ridomil 2E 
can be applied as a topical canker application and as a soil 
application, as a spray or through sprinkler or drip ir.rigation 
systems. If trees are on a drip irrigation system, distribute 
the amount of Ridomi1 2E needed per tree (see tables) to tLe 
soil directly under the drip emitters at each tree. If t~ere is

more than one emitter per tree, distribute the total amount of 
Ridomil 2E needed among the emitters. 
Note: Where nematodes are a problem, best results can be 
achieved if effect1ve EPA-registered nematicides are used. 
Nematicides can be used in combination or in sequence with 
Ridomil applications. 
Precaution: For best Phytophthora control. a combination of 
cultural practices and resistant varieties is recommended. The 
use of Kidomil 2E is not recommended in Florida for use on the 
highly susceptible sweet orange rootstock. 
Citrus in Nurseries (Arizona. ~alifornia. Florida ar.d Puerto 
Rico Only) 
Make the fir~t application of Ridomil 2E at the time of plant­
ing. Make repeat applications at three-month intervals during 
the period when trees are actively growing. For banded applica­
tions, use a band wide enough to cover the root systems of the 
plants. Do not apply Ridomil 2E solutions to bare roots. 
Soil Drench: Apply 4-6 fl. oz./100 gals. of water as a drench 
over tha row at a rate of 100-250 gals./l,OOO feet of row. The 
width of the drench treatment should be wide enough to cover the 
root systems of the plants. Follow with a 1/2-1 inch irrigation 
over the treated area. 
Soil Surface Spray: Apply 1-2 gals./treated acre in a broadcast 
or banded surface spray to seedbeds, liners, or bedded stock in 
sufficient water to obtain thorough coverage. If applications 
are banded, the treated area should be wide enough to cover the 
root systems of the plants. Follow the applications with a 
1/2-1 inch irrigation over the treated area. 
Note: Do not use Ridomil 2E for disease control in greenhouse 
nurseries. 
Citrus Resets or New Plantings (Arizona. California. Florida and 
Puerto Rico Only) 
Make the first application of Ridomil 2E to citrus resets or new 
plantings at the time of transplanting. Make up to three addi­
tional applications per year at three-month intervals or when 
root growth flushes occur. 
Water Ring Drench: 
5 gals. of the mix 
watering ring. 
Mix 4-6 fl. oz./100 gals. of water. Apply 
around the base of each tree within the 
Soil Surface Spray (Arizona and California Only): Apply 
1-2 gals./treated acre (3-6 fl. oz./ 1,000 sq. ft.) in suffi­
cient water to obtain uniform coverage of the scil surface.

-16-
Apply spray to the soil surface beneath the tree canopy or apply 
through irrigation water. If natural rainfall is not expected 
within three days of a soil surface application, irrigate with 
1/2-1 inch water over the treated area. See instructions below 
for application through irrigation water. 
Soil Surface Spray (Florida and Puerto Rico Only) : 
Apply 1 gal./treated acre (3 fl. oz./l,OOO sq. ft.) under the 
canopy of the tree. Applications may be made through low volume 
irrigation systems at the rate of 1 qt./grove acre for trees 
less than 5 years old. Two-three applications per year are rec­
ommended. Applications may be made on a spring + summer, summer 
+ fall or spring + summer + fall schedule. 
Established Plantings 
Soil Applica~ion (Florida and Puerto Rico Only): Apply 
1/2 gal./treated acre to groves that have a Phytophthora propa­
gule count of 10 to 20 per cubic centimeter (cc) of soil as a 
feeder root rot disease maintenance treatment. Applications may 
be made through low volume irrigation for trees 5 years or older 
at the rate of 1 qt./grove acre. Two-three applications per 
year are recommended. Applications may be made on a spring + 
summer, summer + fall or spring + summer + fall schedule. For 
groves with extremely high propagule counts (above 20 per cc of 
soil). apply 1 gal./treated acre for one year (2-3 applications) 
to reduce the popUlation. 
Soil Surface Spray (Arizona and California Only): For best 
results, begin Ridomil applications during the spring root-flush 
period. One or two additional applications per year can be made 
at three-month intervals or to coincide with flushes of root 
growth. Use the following table to determine the proper rate 
based on tree size and the number of applications per year. For 
applications based on broadcast rates, use Ridomil 2E at 
1-2 gals./A (3-6 fl. oz./l,OOO sq. ft.) when three applications 
are planned and at 3 gals./A (9 fl. oz./I,OOO sq. ft.) when two 
applicatior.s are planned. Apply in sufficient water to provide 
uniform coverage or apply through irrigation water. See

Deciduous Fruits and Nuts in Orchards 
(Nonbearingl" 
"For bearing DF&N, see Directions for Use under the Apples and 
Stone Fruits. Walnuts and Almonds sections of this label. 
Phytophthora Diseases 
Use of Ridomil 2E will aid in the control of crown, collar, and 
root rot of deciduous fruit and nut trees caused by Phytophthora 
spp. when used in conjunction with good cultural practices and 
rootstocks that are most tolerant to the disease. Applications 
should be made before symptoms appear, especially in areas 
favorable for disease development. Ridomil 2E will not revital­
ize trees showing moderate to severe disease symptoms. 
On new plantings, make the first application at the time of 
planting (See Notes below.). Additional applications should be 
made at three-month intervals during the time when conditions 
are favorable for disease development. For established plant­
ings, make the first application in the spring before growth 
starts. 
Apply 2 gals./treated acre (6 fl. oz./l,OOO sq. ft.) in suffi­
cient water to obtain uniform coverage of the soil under the 
canopy of the trees. For banded applications, use the formula 
in the General Information section of this label to calculate 
the amount of Ridomil 2E needed per acre. Soil surface sprays 
of Ridomil 2E will not be effective until the fungicide is moved 
into the root zone by rainfall or irrigation. 
Notes: (1) Do not apply to plantings that will bear harvestable 
fruit within 12 months of the last application, or possible 
illegal residues may result. (2) To avoid injury, do not use 
Ridomil 2E to dip or spray tree roots. Do IIOt concentrate it 
around the tree trunks. (3) Do not apply to trees under stress. 
(4) In California, do not apply Ridomil 2E to newly planted 
trees within 90 days of planting. (5) Do not apply more than 
6 gals. of Ridomil 2E/treated acre/year. 
Ginseng 
Ridomil 2E applied to the soil before early spring growth fol­
lowed by applications of Ridomil 5G (see Ridomil 5G label) will 
control Phytophthora root rot in ginseng caused by Phytop­
thora !:actorum. 
Apply Ridomil 2E at 3 pts./A as a drench in 100-400 gals. of

-20-
water uniformly to the soil surface in the sprin~ before the 
plants begin growing. 
Note: Do not make any supplemental applications of Ridomil 2E. 
HopS 
Ridomil 2E applied as a soil drench followed by foliar applica­
tions with Kocide 101 will control downy mildew caused by 
PseudQperonospcr~ humulii. 
Soil Drench: Apply 1 qt. of Ridomil 2E/A of hops in a minimum 
of 20 gals. of water or liquid fertilizer to the soil surface 
over the crowns after pruning, but before training. Early 
application before shoots are 6 inches long is preferable. 
Foliar Spray: When primary infection (spikes) persist after a 
soil drench treatment and/or there is the first evidence of 
secondary (foliar) infection, foliar sprays of Ridomil 2E in 
combination with contact copper fungicides may be used. Apply 
1 qt. of Ridomil 2E/A in a tank-mix combination with 2 lbs. of 
Kocide 101 (or ~n equivalent rate of a comparable copper 
fungicide). Apply with ground equipment in a minimum of 
50 gals. of water/A. 
Notes: To avnid possible illegal residues, (1) Do not make more 
than 3 applications of Ridomil 2E per season (1 soil drench + 2 
foliar sprays) and (2) Do not make the last application within 
45 days before harvest; (3) Do not apply foliar sprays of Rido­
mil 2E without a copper fungicide. 
Leafy Vegetables (Head Lettuce and Spinach Only) 
Ridomil 2E applied as a soil application will control damping­
off caused by pythium spp. in head lettuce and spinach and white 
rust (Albugo occidentalis) and downy mildew in spinach. Appli­
cations may b~ made banded over the row, preplant incorporated, 
or injected with liquid fertilizer. 
Preplant Incorporated Application: Apply 4-8 pts./treated acre 
as a broadcast soil application in sufficient water or liquid 
fertilizer to provide uniform coverage and incorporate in the 
top 2 inches of soil. For banded applications, a 7-inch band is 
recommended. Use the formula in the General Information section 
of this label to calculate the amount of Ridomil 2E needed per 
acre. 
Surface Application: Apply 4-8 pts./treated acre at planting in 
sufficient water or liquid fertilizer to provide uniform cover­
age. For banded applications, a 7-inch band is recommended. 
Use the formula in the General Information section of this label

-21-
to calculate the amount of Ridomil 2E needed per acre. If natu­
ral rainfall is not expected before the seeds start germinating, 
Ridomil 2E should be incorporated mechanically before planting 
or be moved into the seed zone after planting with 1/2-1 inch 
sprinkler irrigation. 
White Rust and Downy Mildew Control (Spinach Only): In addition 
to the preplant incorporated or surface application described 
above, apply 1 pt. of Ridomil 2E/A of crop, shanked in 21 days 
after planting or after the first cutting. One other applica­
tion may be shanked in after the next cutting. A total of 2 
supplemental applications may be used on a 21-day interval. Use 
sufficient mechanical or bypass agitation to keep the Ridomil 2E 
mixed with the water or fertilizer. 
Notes: (1) The additional applications of Ridomil 2E noted 
above and made after each cutting by shanking the fungicide into 
the beds along with liquid fertilizer provide continuing control 
of white rust. However, white rust can only be controlled in a 
preventative disease control program that begins with an appli­
cation of Ridomil to the soil at planting. If Ridomil is not 
used at planting. do not use Ridomil at any other time through­
out the season. Do not apply Ridomil in foliar applications or 
in situations where white rust infections are already estab­
lished. The use of Ridomil 2E in curative applications greatly 
increases the risk of the fungus developing insensitivity to 
metalaxyl. The development of insensitivity will destroy the 
effectiveness of Ridomil in controlling white rust. (2) To 
avoid possible illegal residues, do not harvest spinach within 
21 days of a Ridornil 2E application. (3) Do not use Ridomil 2E 
for disease control in greenhouse crops. (4) Do not apply more 
than 11 pts. of Ridomil 2E/A per growing season in spinach. 
(5) Do not exceed a total of 2.8 Ibs. active ingredient/A of 
metalaxyl per growing season when using a combination of Ridomil 
2E, Ridomil 5G, or Ridomil/Copper 70W in spinach.

Papaya (Hawaii Only) 
Ridomil 2E aids in the control of Phytophthora root rot of 
papaya in nurseries and in new plantings in the field. 
Papaya in Nurseries: Apply Ridomil 2E as a soil drench by mix­
ing 2-4 fl. oz. with 40 gals. of water and applying to 
800 sq. ft. Apply to seedlings 3 to 4 weeks after planting 
seed. Repeat application one month later if necessary. Do not 
apply more than twice per year in the nursery. 
Papaya in the Field - New Plantings: Make the first application 
of Ridomil 2E at the time of transplanting to the field or with­
in one week of transplanting. Apply 3 1/2 to 7 qts./A* of soil 
treated (2 1/2 to 5 fl. oz./l,OOO sq. ft.) as a soil surface 
spray in sufficient water to obtain thorough coverage of the 
soil under the canopy of the trees. After application, immedi­
ately irrigate with 1/8 to 1/4 inch of water. Repeat in 
2-4 weeks if conditions are favorable for disease. Use the 
table below as a guide for treating individual trees. 
Notes: To avoid possible illegal residues, (1) Do not apply 
more than two applications per year in the field to newly trans­
planted stock, and (2) Do not apply within 3 months of harvest.

Ridomil 2E is a soil-applied systemic fungicide for use in con­
trol of seedling and pod diseases of peanuts incited by Pythium 
spp. 
Seedling Diseases: Apply 1 pt./A of crop as an application to 
the seed in-furrow or in a 7-inch band at the time of planting. 
For in-fuc10w applications, position the spray so the fungicide 
is mixed with the soil covering the seed. Avoid spraying the 
~eed directly with the spray solution or crop injury may occur. 
Pod Rot: Apply 1-2 qts./A at early pod set or pegging through 
overheaj irrigation systems. See the General Information 
sec-.ion of this label for further instructions and precautions 
whe.l making applications through irrigation systems.

-24-
Notes: (1) Where pathogens other than Pythium spp. are present, 
use fungicides that control those diseases in combination with 
Ridomil 2E. (2) Where the predominant pod rot pathogens are 
Pythium spp. and Rhizoctonia spp.; use Ridomil PC 11G at labeled 
rates. 
Peppers and Eggplant 
Soil applications of Ridomil 2E will control damping-off caused 
by pythium spp. and crown rot caused by Phytophthora capsici. 
Ridomil 2E must be applied to the soil before the plants are 
infected with Phytophthora to obtain satisfactory disease con­
trol. 
Apply 4-8 pts./treated acre at the time of planting in suffi­
cient water (20-50 gals.) or liquid fertilizer to provide uni­
form coverage. If rainfall is not expected before the plants 
begin growth, Ridomil 2E should be incorporated mechanically 
before planting or be moved into the root zone after planting 
with 1/2-1 inch of sprinkler irrigation water. For banded 
applications, a 12-16 inch band is recommended. After the 
initial application, two supplemental post-directed applications 
at 4 pts./treated A should be made at 30-day intervals. The 
spray should be directed at the base of the plants and cover 6-8 
inches of soil on either side of the plants. Such applications 
must be incorporated mechanically or by sprinkler irrigation to 
move the Ridomil into the root zone. Ridomil 2E may be applied 
with liquid fertilizer shan ked in as a band treatment to either 
side of the plant. Use the formula in the General Information 
section of this label to calculate the amount of Ridomil 2E 
needed per acre. 
Precautions: (1) Ridomi1 may cause some yellowing of the pepper 
leaves. (2) Plants already infected with Phytophthora cannot be 
cured with Ridomil 2E applications. (3) The foliar blight phase 
of Phytophthora cannot be controlled with foliar applications of 
Ridomil 2E. (4) Do not use Ridomil 2E for disease control in 
greenhouses. (5) In areas where there is a history of late 
Phytophthora infections, an application of another EPA­
registered fungicide labeled for Phytophthora control is recom­
mended 17-21 days following the last Ridomil 2E application. 
Notes: To avoid possible illegal residues, (1) Do not apply 
within 7 days of harvest, and (2) Do not apply more than 12 pts. 
of Ridomil 2E per acre of crop per season.

-25-
Pineapple 
Ridomil 2E, applied as a "seed piece" dip, provides effective 
control of heart rot disease of pineapple caused by Phytophthora 
spp. 
Apply Ridomil 2E as a crown dip before planting at the rate of 
1-2 qts./IOO gals. of water. Use 75 to 100 gals. of dip solu­
tion per planted acre, depending on crown size, plant density 
and dipping techniques. 
Note: If there is a crop failure within one year of planting 
treated crowns, do not harvest plant material for animal feed. 
Root and Tuber Vegetables 
Includes artichoke (Jerusalem), beet (sugar* and table), carrot, 
cassava, chicory, ginger, ginseng**, horseradish, parsnip, 
potato***, radish, rutabaga, salsify, sweet potato, tanier, tur­
nip and yams. 
*See separate section for Sugar Beets. 
**See separate section for Ginseng. 
***See ~ at end of section. Do not apply Ridomil 2E to 
potatoes. 
Ridomil 2E applied to the soil at planting will provide control 
of diseases caused by Pythium and Phytophthora spp. Applica­
tions may be made preplant incorporated or as a soil surface 
spray after planting. 
Preplant Incorporated Application: Apply 4-8 pts./treated acre 
as a broadcast soil application in sufficient water or liquid 
fertilizer to provide uniform coverage and incorporate in the 
top two inches of soil. For banded applications, a 7-inch band 
is recommended. Use the formula in the General Information sec­
tion of this label to calculate the atnount of Ridomil 2E needed 
per dose. 
Surface Application: Apply 4-8 pts./treated acre at plantir.g in 
sufficient water or liquid fertllizer to provide uniform cover­
age. For banded applications, a 7-inch band is recommended. 
Use the formula in the General Information section of this label 
to calculate the amount of Ridomil 2E needed per acre. If natu­
ral rainfall is not expected before th~ seeds start germinating, 
Ridomil 2E should be incorporated mechanically before planting 
or be moved into the seed zone after planting with 1/2-1 inch 
sprinkler irrigation. 
Notes: (1) Do not use Ridomil 2E for dise~se control in green­
house crops. (2) To avoid development of insensitivity in the

-26-
pathogen population, do not apply Ridomil 2E to potatoes. 
Soybeans 
Ridomil 2E is a soil-applied systemic fungicide for use in the 
control of Phytophthora root and stem rot and pythium damping­
off. Ridomil 2E may be applied broadcast, banded or in the seed 
furrow before the seeds are covered. The seed furrow applica­
tions will provide more consistent results if rain is not 
expected before the seeds germinate. 
For best results against Phytophthora root and stem rot, use 
Ridomil 2E with soybean varieties that have some tolerance to 
the races of Phytophthora present in the field. The higher rate 
of Ridomil 2E should be used in areas with a history of heavy 
Phytophthora damage. Under heavy late season Phytophthora pres­
sure, Ridomil 2E may not provide complete control. 
Surface Applications: For full season control, apply 
5 pts./treated acre in sufficient water or liquid fertilizer to 
provide uniform coverage at the time of planting. For banded 
applications, a 7-inch band is recommended. Use t~e formula in 
the General Information section of this label to c~lculate the 
amount of Ridomil 2E needed per acre. For early to mid season 
control, apply 1 1/2-3 pts./treated acre. 
In-Furrow Applications: For full season control, apply 
1 1/10 fl. oz./l,OOO linear feet of row as an in-furrow spray in 
5-10 gals. of water or liquid fertilizer at planting. Position 
the spray so the fungicide is mixed with the soil covering the 
seed. Avoid spraying the seed directly with the spray solution 
or crop injury may occur. Use sufficient water or liquid fer­
tilizer to provide uniform coverage. Use the following table to 
determine the amount of Ridomil 2E needed per acre based on row 
spacing. For early to mid season control, apply 
3/10-6/10 fl. oz./l,OOO linear feet of row.

Use of Ridomil 2E will aid in the control of crown, collar and 
root rot caused by Phytophthora spp. when used in conjunction 
with good cultural practices and rootstocks that are most toler­
ant to the disease. Ridomil 2E applications should be made be­
fore symptoms appear, especially in areas favorable for disease 
development. Ridomil 2E will not revitalize trees showing mod­
erate to severe disease symptoms. 
On new plantings, make the first application of Ridomil 2E 2 
weeks after planting. Additional applications should be made at 
2-3 month intervals or during periods most favorable for root, 
crown or collar rot development. 
For established plantings, the application should be mC'de in the 
spring before the plants start growth. Additional applications 
should be made at 2-3 month intervals or to coincide with peri­
ods most favorable for root, crown or collar rot development. 
Apply 2 gals./treated acre (6 fl. oz./l,OOO sq. ft.) in suffi­
cient carrier to obtain thorough coverage of the soil under the 
canopy of the trees. Sufficient surface area should be treated 
in nurseries to cover the root zone of the plants. Up to 3 
applications can be made per year. For banded applications, use 
the formula in the General Information section of this label to 
calculate the amount of Ridomil 2E needed per acre. Soil 
surface sprays of Ridomil 2E will not be effective until the 
fungicide is moved into the root zone by rainfall or irrigation. 
Precautions: (1) Do not dip the roots of trees in Ridomil 2E 
solutions. spray the roots or concentrate it around the tree 
trunks or injury may occur. (2) Do not apply it to trees under 
stress. (3) For intense plantings (2-3 times the normal plant­
ing rate) make applications on a per area basis. i.e .. per acre 
or 1.000 sq. ft. Do not calculate the amount of Ridomil 2E on a 
per tree basis. (4) In California. do not apply Ridomil 2E to 
newly planted trees within 90 days of planting. 
Notes: To avoid possible illegal residues, (1) Do not graze 
livestock in treated areas, and (2) Do not graze or fe~d cover 
crops grown in treated orchards. 
Sugar Be.!rt§ 
Ridomil 2E will provide control of diseases caused by Pythium 
spp. Applications may be made preplant incorporated or as a 
surface spra7 at planting.

-28-
Preplant Incorporated Application: Apply 4-8 pts./treated acre 
as a broadcast soil application il. sufficient water or liquid 
fertilizer and incorporate in the t.op 2 inches of soil. For 
banded applications, a 7-inch band is recommended. Use the for­
mula in the General Information section of this label to calcu­
late the an.ount of Ridomil 2E needed per acre. 
Surface Application: Apply 4-8 pts./treated acre at planting in 
sufficient water or liquid fertilizer to provide uniform cover­
age. For banded application~, a 7-inch band is recommended. 
Use the formula in the General Information section of this label 
to calculate the amount of Ridomil 2E needed per acre. If natu­
ral rainfall is not expected before the seeds begin germinating, 
Ridomil 2E should be incorporated mechanically before planting 
or be moved into the seed zone after planting with 1/2-1 inch 
sprinkler irrigation. 
Note: Do not use Ridomil 2E for disease control in gIeenho'lse 
crops. 
Tobacco 
Ridomi1 2E is a soil-applied systemic fungicide for use in the 
field before transplanting for control of black 3hank 
(Phytophthora parasitica, var. Nicotianae) and blue mold 
(Peronospora tabacina) on all types of tobacco. Ridomi1 2E may 
also be applied in t.obacco plant beds for control of blue mold 
and damping-off cau'3ed by pythium s<>p. For control of anthrac­
nose and other tobacco diseases, use fungicides that control 
those diseases. 
Tobacco Plant Bed 
For control of blue mold and dampir.g-off caused by h ·.hium spp., 
apply Ridomil 2E only as a preplan~ broadcast soil application 
at the rate of 1 qt./treated acre in 50 gals. of water or liquid 
fertilizer (1 fl. oz. or 2 tablespoons/1S0 sq. yds. of bed in 2 
gals. of water or liquid fertilizer). Apply before or at the 
time of seeding to the surface of the plant bed and lightly 
incorporate or follow with 1/2 inch sprinkler irrigation water. 
In Pennsylvania, use 2 qts./treated acre (2 fl. oz. or 4 table­
spoons/1S0 sq. yds. of bed in 2 gals. of water or liquid fertil­
izer) . 
Notes: (1) Do not use Ridomi1 2E for disease control in green­
house crops. (2) Do not dip plants in solutions containir.g 
Ridomil 2E, or crop injury may occur. (3) ro not use Ridomil 2E 
for disease control in floathouse, floatbed production facili­
ties, hydroponic production or greenhouse facility.

Field Planted Tobacco 
Blue Mold: Apply Ridomi.l 2E as a broadcast soil application and 
incorporate in the top 2-4 inches of soil before forming beds. 
For flue-cured tobacco, use 1-2 qts./treated acre, dGpending on 
disease pressure and length of control desired. Under low dis­
ease pressure or for early season control, use 1 qt./treated 
acre. For burley and other tobacco types, use 2 qts./treated 
acre. 
For prolonged control of blue mold in field planted tobacco, 
make a supplemental application of 1 qt./acre of crop as a soil 
application at lay-by or the last cUltivation. I-osition the 
nozzles so that the spray is deposited under the plants and is 
covered by soil by the cultivator. Do not make this application 
if more than 2 qts./A of Ridomil 2E were applied at transplant­
ing or if nc Ridomil 2E was applied at transplanting. 
Note: For best control of blue mold, use Ridomil 2E in the 
plant bed and follow with an application in the field prior to 
transplanting. Do not use Ridomil 2E in transplant water or in 
foliar applications on field totacco because of the potential 
for the development of resistance in the blue mold fungus, crop 
injury or potential excessive residues in the crop. 
Black Shank: Use Ridomil 2E as a broadcast soil application and 
incorporate in the top 2-4 inches of soil before forming beds. 
Apply Ridomil 2E using conventional ground application equipment 
in sufficient water or liquid/dry fertilizer to provide uniform 
coverage. Use the table below to determine the amount of Rido­
mil 2E needed per acre depending on the black shank severity.

Type of Rate of Ridomil 2E 
Tobacco Disease Level in Field Per Acre 
Flue-Cured Low to moderate (less than 2 qts. 
6% disease) 
High (more than 6% 4 qts. * 
disease) 
Burley and Low to moderate (less than 4 qts. 
Other** 6% disease) 
High (more than 6% 6 qts. 
disease) 
*Florida and Georgia - Use 6 qts./treated acre of Ridomil 2E 
in fields with heavy black shank levels (greater than 6%). 
**Pennsylvania - Do not use Ridomil 2E for black shank control. 
For prolonged control ot· black shank in field planted tobacco, 
the following is recommended: Apply Ridomil 2E at 2 qts./A just 
prior to transplanting followed by a second application of 
1-2 qts./A at the first cultivation followed by a third applica­
tion of 1-2 qts./A at lay-by or the last cultivation. 
Note: If more than 2 qts./A of Ridomil 2E were applied at 
transplanting, do not exceed a total of 6 qts./A, including the 
supplemental applications. 
Precautions; (1) For best results against black shank. use 
Ridomil 2E with tobacco varieties that have some resistance to 
black shank and use crop rotation. In fields where there is a 
history of severe black shank. use the highest rate and plant a 
variety that is resistant to the race of Phytophthora present in 
the field. (Burley La hybrids are only resistant to 
Phytophthora Race 0.) (2) Ridomil 2E is not recommended for use 
in high black shank areas on highly susceptible flue-cyred 
varieties such as Hicks. Virginia Gold or White Gold. (3) Fail­
ure to adeguately control nematodes in fields treated with Rido­
mil 2E may re3ult in poor control of black shank. 
No-till Tobacco; Apply Ridomil 2E to the field before trans­
planting for control of black shank and blue mold on all types 
of tobacco. Apply 1-2 qts./treated acre as a preplant, broad­
cast or banded soil application. For banded applications, use 
the formula in the General Information section of this label to 
calculate the amount of Ridomil 2E needed per acre. A supple­
mental lay-by application may be made 30-35 days after planting 
at 1.0 qt./A. Do not make the lay-by application if more than 
2 qts./A of Ridomil 2E were applied at transplanting or if no 
Ridomil 2E was applied at transplanting.

Tomatoes 
Soil applications of Ridomil 2E at planting will provide control 
of damping-off caused by Pythium spp. Soil applications applied 
4-12 weeks before harvest under the vines will control fruit and 
root rot caused by Pythium spp. and Phytophthora spp. 
Damping-Off IPythium spp.l: Apply 4-8 pts./treated acre in suf­
ficient water or liquid fertilizer to provide uniform coverage 
at the time of planting. If rainfall is not expected before the 
seeds start to germinate, Ridomil 2E should be incorporated 
mechanically before planting, during the planting operation, or 
be moved into the seed zone after planting with 1/2 - 1 inch 
sprinkler irrigation. For banded applications, a 7-inch band is 
racommended. Use the formula in the General Information section 
of this label to calculate the amount of Ridomil 2E needed per 
acre. 
Root and Fruit Rot (Phytophthora spp and pythium spp.): 
To aid in the control of root and fruit rot, one or two addi­
tional applications may be made dur~ng the growing season, 
depending on the severity of the conditions for disease infec­
tion. 
Apply 4 pts./treated acre beginning 4-6 weeks after planting. A 
second application may be made as needed up to 4 weeks before 
harvest, but before the last irrigation. Ridomil may be applied 
as a directed soil surface spray under the vines or it may be 
injected into the beds with liquid fertilizer. If less than the 
full bed is treated, use the formula in the General InfOrmation 
section to determine the amount of Ridomil 2E needed per acre. 
If Ridomil is injected into the beds with liquid fertilizer, 
base calculations on a 7-inch band. 
If soil surface sprays are used, the Ridomil must be incorpo­
rated into the soil with 1/2 - 1 inch of rainfall or sprinkler 
irrigation. 
Ridomil may be applied with water or liquid fertilizer. Use the 
test in the General Information section to check for compatibil­
ity with various fertilizers. 
Notes: (1) To avoid possible illegal residues, do not apply 
more than 12 pts./treated acre/season. (2) Keep Ridomil 2E 
suspended in the fertilizer solution with bypass or mechanical 
agitation. Refer to the General Information section for drip 
irrigation instructions. (3) Do not use Ridomil 2E for disease 
control in greenhouse crops.
