FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS
LABEL MAY RESULT IN CROP INJURY. POOR DISEASE CONTROL. OR ILLE­
GAL RES !DUES.
General Information
Ridomil 50W 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 in­
sensitive strains of fungi. Development of insensitivity
cannot be predicted. Therefore, Ciba-Geigy cannot assume
liability for crop damage resulting from insensitive
strain~ of fungi. If treatment is not effective following
the use of Ridomil as recommended, an insensitive strain of
fungi may be present. If the treatment is ineffective due
to the presence of a Ridomil insensitive strain of fungi,
neither Ridomil nor any other fungicide with similar action
will effectively control that disease. Consideration
should then be given to the prompt use of oth~r tyPp.s of
suitable fungicides. Consult with your State Agricultural
Experiment Station or Extension Service Specialist for
guidance on your particular crop and disease control situ­
ation.
Do not make foliar applications to field grown tobacco, or
other crops unless specified since this practice may en­
courage more rapid development of insensitivity.
THIS LABEL IS FOR FIELD USE ONLY AND IS NOT INTENDED FOR
USE ON TRANSPLANT TRAYS. GREENHOUSES, LATH HOUSES. OR IN
BEDDING PLANT STRUCTURES.
Where rate ranges are specified on this label, use the high~r.
rate when heavy disease pressure is expected and the lower .
rate when disease pressure is expected to be light unless
otherw i se noted. ., .. ,.
To avoid spray drift, do not apply under windy conditions.
Avoid spray overlRp, as rrop injury may result.

Mixing Instructions
Prepare no more spray mixture than is needed for the immediate
operation. Thoroughly clean spray equipment before using this
product. Vigorous agitation is necessary to maintain uniformity
of the spray mixture. Maintain maximum agitation throughout the
spraying operation. Do not let the spray mixture stand over­
night in the spray tank. Flush the spray equipment thoroughly
following each use and apply the rinsate to a previously treated
area.
Precautions: (1) water soluble bags of Ridomil SOW must be com­
pletely dissolved and dispersed in plain water before any other
tank mix partner, including micronutrients or other liquid or
dry fertilizers, are added to the spray solution. Boron, espe­
cially in the form of a micronutrient additive, such as
'Solubor®, etc., or as a natural component of the mix water, may
prevent water soluble bags from dissolving. (2) When the spray
carrier is primarily composed of liquid fertilizers (e.g.,
10-34-0 or 9-18-9) soluble bags of Ridomil SOW ~ be slurried
in water following the proced~re as outlined in Ridomi1 50W in
Liquid Fertilizer.
Ridomil SOW Aloke: Add 2/3 of the required amount of plain
water to the spray or mixing tank. With the agitator running,
drop the required number of unopened soluble bags of Ridomil 50W
into the lank all at once. Continue agitation while adding the
remainder of tht water. Begin application of the spray solution
after the bags have dissolved and the material has completely
dispersed into the mix water. Maintain agitation until all of
the mixture has been applied.
BEFORE TANK MIXING RIDOMIL 50W WITH OTHER REGISTERED PRODUCTS
FOR ANY USE ON THIS LABEL. REAP THE LABEL OF THE TANK MIX PART­
NER TO BE CERT~ IT IS LABELED FOR USE ON THE PARTICULAR CROP
AND THAT ~SE PATTERNS ABE :OMPATIBLE WITH THOSE OF RIDOMIL 50W.
Ridomil 50W + Tank Mixtures: Ridomil 50W is usually compatible
with most commonly used insecticides, fungicides, and spray
adjuvants. When using Ridomil SOW in a tank mixture with other
pesticides, observe the most restrictive label limitations and
precautions of the products being used.
Add 2/3 of the required amount of plain water to the spray Gr
mixing tank. With the agitator running, drop the required I.um­
ber of unopene~ soluble bags of Ridomil SOW into the tank aj~ a~
once. Continue agitation while adding the remainder of the
water. Allow the bags of Ridomil SOW to dissolve and the prod~
uct to completely disperse into the mix water. Then add th~"':'
desired amount of other products recommended for tank mixtu~p. •
and allow them to become completely dispersed. Continue agjtA~'
tion to maintain a uniform suspension until all of the spray
solution has been applied.

Ridomil SOW in Liquid Fertilizex: Slurry Ridomil SOW in water.
Add a maximum of 4 unopened soluble bags of Ridomil SOW to
S gallons of clean water. Stir the solution until all of the
soluble bag material has dissolved and the Ridomil SOW has
formed a smooth slurry.
Add 2/3 of the required amount of water and/or liquid fertilizer
to the spray or mixing tank. With the agitator running, add the
Ridomil SOW slurry. If adding other tank mix partners, add the
products in the following order: Ridomil SOW slurry, wettable
powders or dispersible granul~=, and then emulsifiable concen­
trates. Allow each product to disperse before adding the next
one, maintaining agitation the whole time. Triple rinse the
slurry container and add to the spray tank. Add the remainder
of the water and/or fertilizer and continue agitation. Maintain
agitation until all of the mixture has been applied.
APplication Instructions
Apply Ridomil SOW by ground or air in sufficient water to
provide uniform coverage of the soil surface. Apply in a mini­
mum of 20 gals.fA for ground applications and S gals./A by air.
Refer to the specific crop directions for use for application
recommendations.
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 of product per certain row
length (often 1,000 ft.). Others express rates as amount pe~
treated acre which means the total area treated wi~h the pesti­
cide. If rates are expresged as amount per treated a~~e and
banded applications are used, the amount of pesticide used per
acre will be proportionately less. The following formula can be
used to calculate the amount of Ridomil SOW needed per acre of
crop when banded applications are made:
band width in inches broadcast rate amount needed
row spacing in inches X per acre = ger acre of field
Application Through Irrigation Systems
Ridomil SOW, alone or in combination with other fungicides which
are registered for sprinkler irrigation, 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.
Do not apply this product through any other type of irrigation
system. Crop injury, lack of effectivpness, or illegal pesti­
cide residues in the crop can result from non-uniform
distribution of treated water. If yOU have questions aoout
calibration, you should c"ntact State Extension Service special-

ists, equipment manufacturers, or other experts. Do not connect
an irrigation system (including greenhouse systems) used for
pesticide application to a public water system unless the pesti­
cide label"prescribed safety devices for public water systems
are in place. A person knowledgeable of the chemigation system
and responsible for its operation, or under the supervision of
the responsible person, shall shut the system down and make nec­
essary adjustments should the need arise.
Operating Instructions
1. The system must contain a functional che,::k-valve, vacuum
relief valve, and low pressure drain appropriately located
on the irrigcotion pipeline to prevent water-source
contamination from backflow.
2. The pesticide injection pipeline must contain a
functional, automatic, quick-closing check-valve to pre­
vent 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 connected 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 include a func­
tional pressure switch which will stop the water pump
motor whe~ the water pressure decreases to the point where
pesticide distribution is adversely affected.
6. Systems must use a metering pump, such as a positive
displacement injection pump (e.g., diaphragm pump) effec­
tively designed and ccnstructed 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 for treatment.
Ap~lication Instructions
Ridomil SOW must be applied on the schedule specified in the
specific crop use recommendations, not according to the irriga­
tion schedule. If irrigation schedules are used, ground or
aerial applications must supplement chemigation applications to
achieve adequate disease control.
The f0110wing calibration and application techniques are pro­
vided for user reference, but do not constitute a warranty of

Micro Sprinkler or Drip Irrigation Systems
General Instructions
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 eaCL irrigation run.
Measure the output of each of the emitters or drip tubes
closest to and farthest from the injector site.
Fo~ calibration, SUbstitute a concentrated det~rgent (such
as Wisk) for the Ridomil SOW in the injector tank. It is
important to use the same volume of soap solution as the
planned volume of Ridomil 50W solution when calibrating the
syystem. The detergent will bubble as it leaves the emit­
ters. The time period 0ver 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.
~p-by-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 with mixing Fidomil SOw.
Set the injector to apply the indicator solution at the
injection rate to be used in the actual Ridomil SOw ~pplica­
tion.
Attach a 5-inch length of flexible tUbing over the emitter
closest to the injection point, another length over the
1 37
/0
. • -10- fl
emitter farthest away. Both emitters should be monitored 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 2 emitters are within 2 minutes of each other,
comparable coverage will be obtained. If they are not, make
adjustments by increasing the dilution ratio, using more
water per part of Ridomil SOW, or adjust the injector to a
slower flow rate.
Once the system is calibrated, dilute the needed amount of
Ridomil SOW with water using a minimum of 10 parts water to
1 part Ridomil SOW.
Do not begin to inject Ridomil SOW into the system until all
emitters are producing equal flow rates, or until the system
is at full pressure.
Inject the Ridomil SOW into the system at the end of the
irrigation set in 1/2 - 1 inch of irrigation water.

Use of Ridomil SOW 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 SOW applications should be made
before symptoms appear, especially in areas oi the orchard
favorable for disease development. Ridomil SOW will not
revitalize tr~es showing moderate to severe disease symptoms.
Broadcast Spray or Banded Applications: Apply 8 lbs./treated
acre as a broadcast spray (3 oz./l,OOO sq. ft.) in sufficient
water to 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 ~f Ridomil SOW will not be effective until
the fungicide is moved into the root zone by rainfall or irriga­
tion. Applications should be made in early spring before growth
starts and in the fall after harvest, but before the ground
freezes.
Drench: Mix 1 lb. of Ridomil SOW with 100 gals. of water.
AFPly the amount of diluted mixture indicated in the following
table around the trunk of each tree. Applications should be

Begin applications at the start of the growing se~son or at
transplanting. Two additional applications should be made at
3-month intervals. Applications are not needed during the win­
ter months of November through February. Ridomil SOW 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 1/2 oz. of Ridomil SOW with 18 gals. of
water. At the time of transplanting, drench the roots inside
the sleeve with 1 qt. of Ridomil SOW solution per tree.
~e. 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 SOW to
use based on the diameter of the tree canopy. Start applica­
tions 2-t the beginning of the growing season or at transplanting
and continue at 3-month intervals.
Drip IrrigatiQD: Apply the recommended amount of Ridomil SOW
(see table) to the soil directly under the drip emitter at each
tree. If there is more than one emitter per tree, distribute
the total amount of Ridomil SOW needed among the emitters.
Injection into Irrigation Water (Sprinkler or Drip Irrigation
Only): Inject Ridomil SOW into the irrigation water at a rate
of 1-2 oz./l,OOO gals. (3 3/4-7 1/2 ppm active ingredient) at
each irrigation. If Ridomil SOW is not appl~ed at each
irrigation, use the following table to determine how much
Ridomil SOw should be injected into the irrigation water. If
Ridomil SOW is to be used more frequently than every 3 months,
adjust the rates so that no more than the specified amount is
applied during each 3-month period. See the General Information
section of this label for further instructions and precdutions
when making applications through irrigation systems.

Ridomil SOW is a soil-applied systemic fungicide for use in con­
trol of seedling and pod diseases of peanuts incited by Pythium
spp.
Seedling Disea~: Apply 1/2 Ib./A of crop as an application to
the seed in-furrow or in a 7-inch band at the time of planting.
For in-furrow applications,. 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.
~dLB~: Apply 1-2 Ibs./A at early pod set or pegging. Make
applications directly to soil in a 7-inch band.
Notes: (1) Where pathogens other than pythium spp. are present,
use fungicides that control those diseases in combination with
Ridomil SOW. (2) Where the predominant pod rot pathogens are
pythium spp. and Rhizoctonia spp.; use Ridomil PC 11G at labeled
rates.
Soil applications of Ridomil SOW will control damping-off caused
by pyti1ium spp. and crown rot caused by Phytoph.thQ.r.a C-i!ps.ici.
Ridomil SOW must be applied to the soil before the plants are

Apply 2-4 lbs./treated acre at the time of planting in suffi­
cient water (20-S0 gals.) to provide uniform coverage. If rain­
fall is not expected before the plants begin growth, Ridomil SOW
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, 2 supplemental
post-directed applications at 2 lbs./treated acre should be made
at 30-day intervals. The spray should be directed at the base
of the plants and cover 6-8 inch.,s of soil on either side of the
plants. Such applications must b~ incorporated mechanically or
by sprinkler irrigation to move th~ Ridomil SOW into the root
zone. Ridomil SOW may be applied shanked in as a band treatment

amount of Ridomil SOW needed per acre. If natural rainfall is
not expected before the seeds start germinating, Ridomil SOW
should be incorporated mechanically before planting or be moved
into the seed zone after planting with 1/2-1 inch sprinkler
irrigation.
Note: (1) Do not use Ridomil SOW for disease control in green­
house crops or vegetable bedding plants. (2) To avoid develop­
ment of insensitivity in the pathogen population, do not apply
Ridomil SOW to potatoes.
Ridomil SOW is a soil-applied systemic fungicide for use in the
control of Phytophthora root and stem rot and Pythium damping­
off. Ridomil SOW may be applied broadcast, banded, or in the
seed furrow before the seeds are covered. The seed furrow
applications 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 SOW with soybean varieties that have some tolerance to
the races of Phytophthora present in the field. The higher rate
of Ridomil SOW should be used in areas with a history of heavy
Phytophthora damage. Under heavy late season Phytophthora pres­
sure, Ridomil SOW may not provide complete control.
Surface Applications: For full season control, apply
2 1/2 Ibs./treated acre in sufficient water to provide uniform
coverage at the time of planting. For banded applications, a
7-inch band is recommended. Use the formula in the Gen~
l_ntorrll<ltion section of this label to calculate the amount of
Ridomil sow needed per acre. For early- to mid-season control,
apply 3/4-1 1/2 lbs./treated acre.

Use of Ridomil SOW 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. Ridomi1 SOW applications should be made
before symptoms appear, especially in 3reas favorable for dis­
ease development. Ridomil SOW will not revitalize trees showing
moderate to severe disease symptoms.
On new plantings, make the first application of Ridomil SOW two
weeks after planting. Additional applications should be made at
2-3 month intervals or during periods most favorable for root,
~rown, or collar rot development.
For est 'blished plantings, the application should be made 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.

formula in the General Information section of this label to cal­
culate the amount of Ridomil SOW needed per acre. Soil surface
sprays of Ridomil SOW 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 SOW
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 SOW on
a per tree basis. (4) In CA. do not apply Ridomil SOW 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 feed cover
crops grown in treated orchards.

also be applied in tobacco plant beds for control of blue mold
and damping-off caused by Pythium spp. For control of anthrac­
nose and other tobacco diseases, use fungicides that control
those diseases.
Tobacco Plant Bed
For control of blue mold and damping-off caused by Pythium spp.,
apply Ridomil SOW only as a preplant broadcast soil application
at the rate of 1 lb./treated acre in 50 gals. of water or liquid
fertilizer (1/2 oz./lSO 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. In PA,
use 2 lbs./treated acre (1 oz./lSO sq. yds. of bed in 2 gals. of
water) .
Notes: (1) Do not use Ridomil SOW for disease control in green­
house crops. (2) Do not dip plants in solutions containing
Ridomil SOW, or crop injury may occur. (3) Do not use Ridomil
SOW for disease control in floathouse, floatbed production
facility, hydroponic production, or greenhouse facility.
Field Planted Tobacco
Blue M~: Apply Ridomil SOW as a broadcast soil application
and incorporate in the top 2-4 inches of soil before forming
beds. For flue-cu~ed tobacco, use 1-2 Ibs./treated acre,
depending on disease pressure and length of control desired.
Under low disease pressure or for early season control, use
1 Ib./treated acre. For burley and other tobacco types, use
2 Ibs./treated acre.
For ~QlQnged contIQ1 of blue mold in field planted tobacco,
make a supplemental application of 1 lb. per acre of crop as a
soil application at lay-by or the last cultivation. Position
the nozzles so that the spray is deposited under the plant~ and
is covered by soil by the CUltivator. Do not make this applica­
tion if more than 2 lbs./A of Ridomil SOW was applied prior to
transplanting or if no Ridomil SOW was applied prior to trans­
planting.
NQLe: For best control of blue mold, use Ridomil SOW in the
plant bed and follow with an application in the field prior to
transplanting. Do not use Ridomil SOW in transpla.lt water on
field tobacco because of the potential for crop injury. Do not
use Ridomil SOW as a foliar spray to field planted tobacco.
Black Shank: Use Ridomil SOW as a broadcast soil application
anrl in~orpo[ate in the top 2-4 inches of soil before forming
beds. Apply Ridomil SOW using conventional ground application

) Soil applications of Ridomil SOw at planting will provide con­
trol of damping-off caused by fythium 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.): Apply 2-4 Ibs./treated acre in suf­
ficient water to provide uniform coverage at the time of plant­
ing. If rainfall is not expected before the seeds start to
germinate, Ridomil SOW should be incorporated mechnJ ically
before planting, during the planting operation, or be moved into
the seed zone after planting with 1/2 - 1 inch sprinkler irriga­
tion. 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 SOW needed per acre.
Root and Fruit Rot IPhytophthora spp and pythium spp.)
To aid in the control of root and fruit rot, 1 or 2 additional
applications may be made during the growing season, depending on
the severity of the conditions for disease infection.
Apply 2 Ibs./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 SOW may be
applied as a directed soil surface spray under the vines or it
may be injected into the beds. If less than the full bed is
treated, u~e the formula in the General Information section to
determine ti'2 amount of Ridomil SOW needed per acre. If Ri1o:nil
SOW is injected into the beds, base calculations on a 7-inch
band.
If soil surface sprays are used, the R1domi1 SOW must be incor­
porate~ into the soil with 1/2 - 1 inch of rainfall or sprinkler
irrirJat ion.
