FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS 
LABEL MAY RESULT IN POOR DISEASE CONTROL OR CROP INJURY. 
General Information 
Ridomil 5G is a systemic fungicide which provides control of 
certain diseases caused by members of the Oomycete class of 
fungi on selected crops. 
~: Do not use in nurseries, turf, or landscape plantings 
unless specified in this label. 
~: Metalaxyl is a systemic fungicide having a specific 
mode of action and could be subject to development of resis­
tant strains of fungi. Development of resistance cannot be 
predicted. Therefore, Ciba-Geigy cannot assume liability for 
crop damage resulting from resistant strains of fungi .• If 
treatment is not effective following the use of Rid~il 5G as 
recommended, a resistant strain of fungi may be present. If 
the treatment is ineffective due to the presence of a meta­
laxyl resistant strain of fungi, neither Ridomil 5G nor any 
other fungicide 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 in your particular crop and 
disease control situation. DO NOT USE RIDQMIL 5G FOR DISEASE 
CONTROL IN CROPS GROWN IN GREENHOUSES. LATH HOUSES OR IN 
BEDDING PLANT STRUCTURES.

Calculate the amount of Ridomil 5G needed for band treatment by 
the formula: 
band width in inches X 
row spacing in inches 
Applicator Settings 
broadcast r~te ~ amount needed 
per acre per acre of 
field 
It is important the user calibrate each individual granular 
applicator before its use. The settings in the chart in the 
Soybeans section of the label SHOULD ONLY BE USED AS A STARTING 
POINT. Even after calibration, it is best to check the actual 
application rate under your operating conditions. Application 
rates ca~ vary due to changing moisture conditions, equipment 
wear, normal variation in product with density and particle size 
distribution.

-5-
Calibraticn: To calibrate a granular applicator, follow the 
procedure as outlined below: 
1. Fill the hopper with Ridomi1 SG. 
2. Attach a plastic bag to the spout opening. 
3. Refer to the appropriate chart in the Soybeans section of 
this label and adjust the setting on the applicator to 
match the desired rate per acre. 
4. Measure off 1,000 linear ft. and drive at the speed 
selected. 
5. Weigh or measure the volume of each bag, change settings as 
needed to obtain the desired rate and repeat steps 2-5 
until the setting delivers the correct number of ounces per 
1,000 ft. 
6. Repeat steps 1-5 for each applicator box. 
Conversions: 
1. Time to cover 1,000 ft. at: 
4 mph ~ 2 mins. 50 secs. 
5 mph = 2 mins. 16 secs. 
6 mph ~ 1 min. 57 secs. 
2. Ounces (wt.) of granules to approximate ounces (volume): 
6 oz. wt. = 8 fl. oz. (1 level cup) 
When calibrating granular applicators, follow the recommenda­
tions below: 
- --'" 
." 
1. To reduce granule flow 
by moving the controls 
the closed position to 
variability, adjust orifice openings 
in one direction only, such as from- .. 
~.., 
2. Granule flow through an orifice is not always proportional 
to ground speed, so make calibration checks at the same ~--. 
speed you plant at and maintain that ground speed as con­
stant as possible when planting. 
3. Granular pesticide products vary considerably in size, den­
sity ana particle shape, so recalibrate applicators when­
ever you change brands and/or formulations. The same brand 
can even change from year to year. 
4. Changing humidity and t81 .. perature during the day can change 
the flow rate of granules through the applicator's orifice. 
Recalibrate when conditions change and periodically read­
just orifice settings to compensate. 
5. Know the recommended rate. For banded applications, the 
{ IUl lUlU8lE CO~ ,

area actually is the area covered by the band, not total 
cropland area planted. Some row-crop recornrnenda~ions are 
based on treating in-the-row and these rates generally are 
specified as amounts (ounces) of granules per certain row 
length (often 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 formula above can be used to calculate the amount of 
Ridomil SG needed per acre of crop when banded applications 
are made. 
6. Calibrate frequently. There are several acceptable 
calibration methods. Learn one. Do the arithmetic first, 
then complete the material collection phase under field 
conditions. 
Preharvest Intervals 
Unless otherwise stated in the directions for use for a specific 
crop, there is no preharvest interval for Ridomil SG. 
Avocados 
Ridomil SG is a systemic fungicide which provides control of 
avocado root rot caused by Phytophthora cinnamomi. For best 
results, Ridomil SG should be used before or as soon as early 
symptoms of disease appear. For new plantings, the use of 
Phytophthora resistant root stocks with Ridomil SG is recom­
mended. Mature trees in advanced stages of decline cannot: be 
cured with Ridomil SG. Applications are not needed during the 
winter months of November through February. _ 
Sprinkler Irrigation: Apply 3/4-1 1/2 oz./sq. yd. evenly to the 
soil surface under the canopy of the tree. The following tablS"-· 
below shows the amount of Ridomil SG to use based on the diame~ 
ter of the tree canopy. Start applications at the beginning ~ 
the growing season or at transplanting and make 2 additional ~_ 
applications at three-month intervals. 
Drip Irrigation: Place the recommended amount of Ridomil SG 
(see following table) on the soil surface directly around the 
drip emitter at each tree. If there is more than 1 emitter per 
tree, distribute the total amount of Ridomil SG among the emit­
ters. Start applications at the beginning of the growing season 
or at transplanting and make 2 additional applications at 
three-month intervals.

Citrus 
Includes grapefruit, lemons, limes, oranges, tangelos, tanger­
ines, citrus citron, kumquats and hybrids of these. 
Use Ridomil 5G on citrus to control citrus foot rot, root rot, 
and trunk canker caused by Phytophthora spp. Apply to the soil 
as a broadcast application under the canopy of the trees. If 
rain is not expected within 3 days of application, water in with 
1/2-1 inch of irrigation. For banded applications, use the for­
mula in the General Information section for calculating the 
amount of Ridomil 5G needed per acre of trees. If the trees are 
on a drip irrigation system, distribute the amount of Ridomil 5G 
needed per tree (see table) to the soil surface in the immediate 
vicinity of the drip emitter(s) at each tree. If there i3 ".ore 
than 1 emitter at each tree, distribute the.total amount of 
Ridomil 5G needed among the emitters. __ 
Notes: (1) Where nematodes are a problem, best results can 
achieved if effective EPA-registered nematicides are used~ 
Nematicides can be used in combination orin sequence with 
Ridomil 5G applications. (2) For all citrus, do not apply 
th"'.n a total of 240 lbs. of Ridomil 5G/treated acre/year.

applications . ould be made before symptoms appear, especially 
in areas favorable for disease development. Ridomil 5G will 1I0t 
revitalize trees showing moderate to severe disease symptoms. 
Make the first application at the time of planting. (See Notes 
below.) Up to 2 additional applications should be made at 
2-3 month intervals during the time when conditions are favor­
able for disease development. For established plantings, make 
the first application in the spring before growth starts. 
Apply 80 lbs./treated acre (30 oz./l,OOO sq. ft.) uniformly 
under the canopy of the tree. The treated area is based on the 
area under the tree caDopy or the area of the row to be treated 
(similar to herbicide strips). Use the formula in the General 
Information section for calculating the amount of Ridomil 5G 
needed per acre of trees. Soil surface applications of Ridomil 
5G will not be effectivp. 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. To avoid injury, (2) Do not treat 
the roots directly or concentrate the granules around the tree 
trunks. (3) Do not apply to trees under stress, and (4) In 
California, do not apply Ridomil 5G to newly planted trees with­
in 90 days of planting.

Soybeans 
IS 1 ).3 
Ridomil 5G is a systemic fungicide for use in the control of 
Phytophthora root and stem rot and Pyt~ium damping-off. Ridomil 
5G may be applied in a 7-inc~ band over the row at plantin~ or 
in the seed furrow before the seeds are covered. The seed fur­
row application will provide more consistent results if rain is 
not expected before the seeds germinate. 
For best results against Phytophthora root and stem rot, use 
Ridomi1 5G with soybean varieties that have some tolerance to 
the races of Phytophthora present in the field. The high rate 
of Ridomil 5G should be used in areas with a history of severe 
Phytophthora damage. Under severe late season Phytophthora 
pressure, Ridomil 5G may not provide complete control. 
Pythium and Phytophthora: For full season control apply 
6 oz./l,OOO linear ft. of row in a 7-inch band over the row or 
as a seed furrow application at the time of planting. For 
early- to mid-season control only, apply 1 1/2 - 3 oz./l,OOO 
linear ft. of row in the seed furrow. When making seed furrow 
applications, position the applicator tubes so the granules are 
mixed with the soil covering the seed or are applied in a 
"T-band." Use the following table to determine :::he amount of ~ ...

Spinach 
Ridomil 5G applied as a soil application will control d.~mping 
off in spinach caused by pythium spp., white rust 
(Albugo occidentalis) and downy mildew. Applications may be 
made preplant incorporated or preemergence. 
Preplant Inco~orated Applicati2n: Apply 20-40 lbs./treated 
acre as a broadcast soil application and incorpo~ate in the top 
2 inches of soil. For banded applications, a 7-inch band is 
recommended. Use 1:he formula in the General Information section 
of this label to calculate the amount of Ridomil 5G needed per 
acre. When incorporated applications are made at the time of 
planting, position the drop tubes so the granules are mixed with 
the soil covering the seed at a rate of 10-20 oz. of gran­
ules/1,000 linear ft. of row. Avoid placing the granules 
directly in contact with the seed or injury may occur. 
Surface Application: Apply 20-40 lbs./treated acre uniformly to 
the soil surface at the time of planting. For banded applica­
tions, a 7-inch band is reco~ended. Use the formula in the 
General InfOrmation section of this label to calculate the 
amount of Ridomil 5G needed per acre. If natural rainfall is 
not expected before the seeds start germinating, Ridomil 5G 
should be incorpc,rated mechanically before planting or be moved 
into the seed zone after planting with 1/2-1 inch spriLkler 
irrigation. 
White Rust and Downy Mildew Control: Make the first application 
at the time of planting according to the above directions. Make 
up to 2 additional applications of 5 lbs. of Ridomil 5G/A-of ~ .. 
crop as a side dress application. Make the first side dress 
appli~ation 40-50 days after planting or after the first c~t­
ting. One additional application may be made after· the next 
cutting. 
Notes: (1) Wh:.te rust and downy mildew can oily be controlled~ 
in a preventative disease control program that begins with an~~ 
application of Ridomil 5G or Ridomil 2E to the soil at planting~._ 
If Ridomil is not used at planting, do not use Ridomil·at any '­
other time throughout the season. Do not apply Ridomil 5G where. 
rust or dow:ly mildew infections are already established. The 
use of Ridomil 5G in curative applications greatly increases the 
risk of the fungug developing resistance to metalaxyl. The 
develor~ent of resistance will destroy the effectiveness of 
Ridomi~ in controlling white rust. (2) To avoid possible 
illegal residues, do not harvest spinach within 21 days of a 
Ridomil 5G application.

diseases caused by pythium spp. Applications may be made pre­
plant incorporated or as a surface application at planting. 
I~ 
Preplant Inco~porated Application: Apply 20-40 lbs./treated 
acre CiS a broadcast soil application and incorporate ir.to 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 5G nepded per 
acre. 
Surface Application: Apply 20-40 lbs./treated acre at planting. 
For banded application, a 7-inch band is recommended. Us~ the 
formula in the General Information se~tion of this label to 
calculate the amount of Ridomil 5G needed per ar:-re. If lIcitural 
r3infall is not expected before the seeds begin germinating, 
Ridomil 5G should be in. orporated mechan~~ally before planting 
or be moved into the seed zone after pl~nting with 1/2-1 inch 
sprinkler irrigation. 
Tomatoes 
Soil applications of Ridomil 5G at planting will provide control 
of damping-off caused by pyLhium spp. and soil applications 
applied 4-12 weeks before harvest under the vines will reduce 
fruit and root rot caused by Pythium spp. and Phytophthora spp. 
Damping-Off IPyth:uro spp.): Apply 20 lbs./treated acre uniform­
ly over the surface of the soil at the tiree of planting. If 
natural rainfall is not expected before the speds begin germi­
nating, Ridomil 5G should be incorporated mechanically with 
1/2-1 inch sprinkler irrigation. For banded applicatio!l:ir a 
7-inch band is recommended. Use the formula in the General 
Information section of this label to calculate the amount of 
Ridomil 5G needed per acre. . 
Fruit and Root Rot IPythium spo. and PhytophthoTa spo.): ~ddi--", 
t ional applications can be made as soil sllrface applications ~ 
under the vines to provide control of root and fruit rot. If~­
only 1 application is planned, apply 20 Ibs./treated acre under 
the vines 4 weeks after t-'1e planting application to 4 weeks "'t:--­
before harvest, depending on the expected occurrence of the dis­
eases. If root and fruit rot is a problem throughout the 
growing season or the occurrence of diseases cannot be pre­
dicted, make 2 additional applications at 1, lbs./treated acre 
under the vines, one 4· ~ weeks after the ~~anting application 
and another 4 weeks before harvest. If rainfall is not expected 
within 3 days of the application, follow as 300n as possible 
with 1/2-1 inch overhead irrigation. Use the formula shown in 
the General Information section to determine the amount of 
Ridomil 5G needed per acre. 
Ridomil 5G can be shanked into the beds with fertilizer. For 
calculating the amount of Ridomil 5G needed per acre, apply the

same amount as would be applied on a 7-inch band at 
20 1bs./treated acre. To obtain uniform disease control, 
Ridomil SG must be mi~ed uniformly with the fertilizer. 
Notes: To avoid possible illegal residues, (1) Do not apply 
more than 40 lbs./treated acre/season, and (2) Do not apply 
within 7 days of harvest. 
If replanting is necessary, additional applications of Rido.nil 
can be made provided that the total amount of metalaxyl applied 
does not exceed the maximum specified on the product label for 
the particular crop.
