FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS 
LABEL MAY RESULT IN POOR DISEASE CONTROL OR CROP INJURY. 
General Information 
Subdue Granular Fungicide is a systemic fungicide for use in 
ornamentals, turf, vegetable plant beds, nonbearing citrus, 
conifers and nonbearing deciduous fruit and nut trees in 
nurseries. 
Note: 1) Subdue is a systemic fungicide having a specific 
mode of action. Use of Subdue could result in development 
of resistant strains of fungi. Development of resistance 
cannot be predicted. Therefore, Ciba-Geigy cannot assume 
liability for crop damage ~esulting from resistant strains 
of fungi. Consult with your State Agricultural Experiment 
Station or Extension Service Specialist for guidance and 
ways to control any possible Subdue resistant strains of 
fungi which may occur. 2) To help decrease the chance of 
downy mildew resistance, do not use Subdue for control of 
downy mildew diseases, except for use in turf. Use Subdue 
only as a soil application for control of soil-borne dis­
eases. 
Calibration Instructions 
It is important to calibrate the granule applicator before use. 
Even after calibration, it is best to check the actual applica­
tion rate under your operating conditions. Application rates 
can vary due to changing moisture conditions, equipment wear, 
.normal variation in·product bulk density and particle size dis-
tribution.

-5-
Generally, calibrating a granule applicator can be done by fol­
lowing these simple steps: 
1. Mark off a known area, usually 1,000 square feet. 
2. At normal walking speed, simulate an application over the 
1,000 square foot area and record the time taken to accom­
plish this. 
3. Fill the applicator hopper with product. Set the applicator 
meter at a random setting. 
4. Operate the applicator for the amount of time obtained in 
step 2 and collect the output of granules in a plastic bag, 
catch pans or other collection device. 
5. Weigh the granules collected in ounces and compare this 
weight with the required application rate in ounces per 
1,000 square feet from the product label. Repeat steps 1-4 
until the correct meter setting is found that will deliver 
the required application rate. 
Ornamentals 
For control of damping-off, and root and stem rot diseases 
caused by pythium and Phytophthora, use Subdue Granular 
Fungicide on container, bench, or bed-grown ornamentals in 
greenhouses or outdoor nurseries, and for professional use on 
ornamentals grown for indoor and outdoor landscaping. Use this 
product either as a soil surface application or soil mix on 
ornamentals at the time of seeding and transplanting. Within a 
rate range given for a specific group of ornamentals. use the 
lower rate for the shortest interval listed and the higher rate 
for the longest interval. Under severe disease conditions. use 
the highest rate and the shortest interval specified. 
When applying Subdue Granular Fungicide to the soil surface. 
irrigate with enough water to completely wet the root zone after 
application. Do not exceed recommended rates or apply more 
frequently than directed. or plant injury may occur.

-6-
Notice to User: Plant tolerances to Subdue have been found 
to be acceptable for the specific genera and species listed 
on this label. Due to the large number of species and 
varieties of ornamentals and nursery plants, it is impossi­
ble to test everyone for tolerance to Subdue. Neither the 
manufacturer nor the seller has determined whether or not 
Subdue can be used safely on ornamentals and nursery plants 
not specified on this label. The professional user should 
determine if Subdue can be used safely prior to commercial 
use. In a small are~, test the recommended rates for a par­
ticular group of unlabeled plants, i.e., foliage plants, 
bedding plants etc., for plant tolerance prior to widespread 
use. 
When applying Subdue Granular Fungicide as a soil mix. 
components in the soil mix should be dry and free of lumps to 
ensure thorough mixing of the granules throughout the media. 
When making subsequent applications at the designated intervals. 
other registered Subdue formulations may be used. Refer to the 
respective product label for rates. precautions. and limitations 
relative to its use.

Citrus in Nurseries (Nonbearingl 
Use Subdue Granular Fungicide on nonbearing citrus for control 
of citrus foot rot, root rot, and trunk canker caused by 
PhytQphthora spp. Apply to the soil as a broadcast application 
under the canopy of the trees. If rain is not expected within 
three days of application, water in with 1/2 inch of irrigation. 
For banded applications, use the formula below for calculating 
the amount of Subdue Granular Fungicide needed per acre of 
trees. 
Make the first application of Subdue Granular Fungicide at the 
time of planting and make two additional applications at three­
month intervals thrcughout the growing season. Apply 200 lbs./A 
as a broadcast or banded application to the seedbeds, liners or 
bedded stock. For banded applications, use a band wide enough 
to cover the root systems of the plants. Follow the application 
with 1/2 inch of irrigation if rainfall is not expected within 
three days. 
Calculate the amount of Subdue Granular Fungicide needed for 
band treatment by the formula:

Subdue Granular Fungicide provides control of pythium root rot 
and Phytophthora root, crown, and collar rot of nonbearing 
deciduous fruits and nuts. 
Make the first application of Subdue Granular Fungicide at the 
time of planting. Additional applications should be made at 
three-month intervals throughout the growing season. 
Apply 200-400 lbs./treated acre (4.75-9.25 lbs./I,OOO sq. ft.) 
uniformly under the canopy of the trees. Treat sufficient 
surface area in nurseries to cover the root zone of the trees. 
Use the high rate in areas known to be infested with 
Phytophthora. 
Note: Do not apply to trees that will bear harvestable fruit 
within 12 months of application, or illegal residues may result.

Turf 
Subdue Granular Fungicide controls Pythium blight and pythium 
damping-off in turf, yellow tuft (downy mildew) in bluegrass, 
and downy mildew in St. Augustinegrass. Within the rate range 
given for turf. use the lower rate for the shortest interval 
listed and the higher rate for the longest interval. Under 
severe disease conditions. use the highest rate and shortest 
interval specified.

immediately after seeding. Irrigate with 
1/4-1/2 inch water. Re-treat at 7-14 day 
intervals if conditions remain favorable 
for disease. 
Precaution: To minimize the potential for resistance. (1) Make 
no more than three applications of Subdue Granular Fungicide per 
season and (2) Apply an alternate EPA-registered fungicide for
