DIRECTIONS FOR USE

GENERAL INSTRUCTIONS

Do not premix Penncozeb 75DF Fungicide into a smaller tank. Pour Penncozeb 75DF Fungicide slowly into a 1/4 filled spray tank while the agitator is running. Fill tank with water. Add other co-applied fungicides, insecticides, growth regulators, micronutrients, and spray adjuvants after Penncozeb 75DF Fungicide dispersible granular fungicide has been placed into suspension. Do not let Penncozeb 75DF Fungicide settle out in an unagitated spray tank. Rinse out spray tank, pumps, and nozzles at the end of the day.
When preparing spray solutions for use in a hand sprayer, premix as a slurry in a small container, and then add to sprayer containing ⅓ to ½ the desired final water volume.
Penncozeb 75DF Fungicide is believed compatible with most of the common pesticides used. Thorough, uniform coverage is essential for good disease control. For low volume airblast sprayers, adjust the mixing rate accordingly.

AERIAL APPLICATION

Apply only by fixed-wing or rotary aircraft equipment, which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label.
Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on this label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment.
Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices.
Use Precautions: Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/Provincial/Territorial Committee on Pest Management and Pesticides.
Do not apply to any body of water. Avoid drifting of spray onto any body of water or other nontarget areas. Specified buffer zones should be observed.
Coarse sprays are less likely to drift, therefore, avoid combinations of pressure and nozzle type that will result in fine particles (mist). Do not apply during periods of dead calm or when wind velocity and direction pose a risk of spray drift. Do not spray when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.
Operator Precautions: Do not allow the pilot to mix chemicals to be loaded onto the aircraft.
Loading of premixed chemicals with a closed system is permitted.
It is desirable that the pilots have communication capabilities at each treatment site at the time of application.
The field crew and the mixer/loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup and repair. Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label.
All personnel on the job site must wash hands and face thoroughly before eating and drinking. Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly.
Product Specific Precautions: Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 800-438-6071, or obtain technical advice from the distributor or your provincial agricultural representative. Application of this specific product must meet and/or conform to the following:
Volume: Apply the recommended rate in a minimum spray volume of 25 liters per hectare.

Resistance-Management Recommendations:

For resistance management, please note that Penncozeb 75DF Fungicide contains a Group M fungicide. Any fungal population may contain individuals naturally resistant to Penncozeb 75DF Fungicide and other Group M fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the same fields.
Other resistance mechanisms that are not linked to site of action but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay fungicide resistance:
Where possible, rotate the use of Penncozeb 75DF Fungicide or other Group M fungicides with different groups that control the same pathogens.
Use tank mixtures with fungicides from a different group when such use is permitted.
Fungicide use should be based on an IPM program that includes scouting, historical information related to pesticide use and crop rotation and considers cultural, biological and other chemical control practices.
Monitor treated fungal populations for resistance development.
If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide with a different target site of action, if available.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for specific crops and pathogens.
For further information and to report suspected resistance, contact United Phosphorus, Inc. at 1-800-438-6071.

VEGETABLES

POTATOES - For early and late blight. Begin applications early, applying 1.1 kilograms Penncozeb 75DF Fungicide per hectare when plants are 10-15 cm high. Increase to 1.75 kilograms per hectare as plants increase in size, and to 2.25 kilograms per hectare at row closure. Apply every 7-10 days throughout season.
Reduced Spray Interval Schedule
During periods of wet weather favoring late blight and/or vigorous crop growth, spray intervals may be reduced to 5-6 days. Apply 1.1 kilograms per hectare until row closure then increase the rate to 1.75 kilograms per hectare until conditions allow the return to the regular spray schedule.
Thorough, uniform coverage is essential for good disease control. Use 40 liters of water per hectare for aerial applications. Do not apply within 1 day of harvest.
TOMATOES – For control of early and late blight, Anthracnose, Stemphyllium blight (gray leaf spot). Use Penncozeb 75DF Fungicide at 1.10 to 3.25 kilograms per hectare in sufficient water to provide adequate coverage. Start applications when disease is first reported in the area and repeat every 7 to 10 days or more often under severe disease conditions. Do not apply within 7 days of harvest. DO NOT APPLY BY AIR.
ONIONS – For control of Botrytis leaf blight (leaf spot or blast). Apply 2.25 to 3.25 kilograms per hectare when disease first appears and repeat every 7 days as needed. Add a suitable wetting agent. Do not use on green bunching onions. Do not use later than 10 days before harvest. DO NOT APPLY BY AIR.
CELERY – For early and late blight. Begin spraying at 2.25 kilograms per hectare in the plant bed when plants first come through the ground. Make further applications at 3-5 day intervals until plants are set in field. Continue field applications on a regular weekly schedule. Do not apply later than 14 days before harvest. Strip, trim and wash the celery at harvest. DO NOT APPLY BY AIR.
CARROTS – For leaf spot diseases. Start applications of 2.25 kilograms per hectare when plants are 6 weeks old or when disease threatens. Repeat at 7-10 day intervals. Do not apply later than 7 days before harvest. Do not use treated tops for food or feed. DO NOT APPLY BY AIR.
CANTALOUPE, CUCUMBERS, PUMPKIN, SQUASH, MELONS AND WATERMELONS – For control of Downy Mildew, Anthracnose, Scab, Gummy Stem Blight and Alternaria Leaf Spot. Use Penncozeb 75DF Fungicide at 1.10 to 3.25 kilograms per hectare in sufficient water to provide adequate coverage. Start applications when runners begin to form or at first sign of disease and repeat at weekly intervals.
Direct spray for thorough coverage of both upper and lower leaf surfaces. Do not apply within 14 days of harvest. DO NOT APPLY BY AIR.

FRUIT

APPLES - For the control of scab, cedar apple rust and quince rust. For a protective schedule begin application of Penncozeb 75DF Fungicide in the green tip up to half inch green sprays.
Repeat any subsequent pre-bloom, bloom and cover sprays in accordance with the timing in your local schedule for a protective program. Use 2.0 kilograms of Penncozeb 75DF Fungicide per 1000 liters of water in single strength sprays or the equivalent in concentrate sprays. If moderate disease conditions prevail, the dosage can be reduced to
1.5 kilograms in the cover sprays. The addition of a wetting agent will ensure a smoother more even coverage of your spray material and help prevent blotchy, visible residues.
Fruit color and finish on most apple varieties sprayed with Penncozeb 75DF Fungicide have frequently been outstanding. Do not apply within 45 days of harvest. DO NOT APPLY BY AIR.
CAUTION – Do not feed treated apple pomace to livestock.
