GENERAL INFORMATION

Gavel DF Fungicide is a broad-spectrum protectant fungicide. Optimum disease control is achieved when the fungicide is applied in a regularly scheduled preventative spray program.

Use Rate Determination
Carefully read, understand, and follow label use rates and restrictions. Under low disease conditions, minimum label rates per application can be used while maximum label rates and the minimum interval may be used for severe or threatening disease conditions. For proper application, determine the number of hectares to be treated, the recommended label use rate and the water to be applied per hectare. Prepare only the amount of spray solution required to treat the measured area. Careful calibration of spray equipment is recommended prior to use.

APPLICATION DIRECTIONS

DO NOT apply by hand.
DO NOT apply using handheld equipment.
DO NOT apply in greenhouses.
GROUND Application Directions for Use
Thorough coverage foliar sprays generally result in optimum disease control. To achieve good coverage use proper spray pressure, water volume per hectare, nozzles (generally hollowcone), disc (generally D5 to D7), nozzle spacing, and tractor speed. Consult spray nozzle accessory catalogues for specific information on proper equipment calibration.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the
American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
Airblast application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT direct spray above plants to be treated. Turn off outward pointing nozzles at row ends and outer rows. DO NOT apply when wind speed is greater than 16 km/hr

AERIAL Application Directions for Use
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO
NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Reduce drift caused by turbulent wingtip vortices. Nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.
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/crop, this product cannot be applied by any type of aerial equipment for that use/crop.
Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices

Aerial Use Precautions
Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only when the potential for drift beyond the area to be treated is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment, and sprayer settings. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federa/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 non-target 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.

Aerial 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 pilot have communication capabilities at each treatment site at the time of application.
The field crew and the mixer/loaders must wear coveralls over long-sleeved shirt and long pants, chemical resistant gloves, shoes plus socks, protective eyewear and a chemical resistant apron 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 1-800-960-4318 or obtain technical advice from the distributor or your provincial agricultural representative. Application of this product must meet and/or conform to the following:
Volume: Apply the recommended spray volume rate of 45 to 90 liters of water per hectare. Use 90 liters under high disease pressure to provide better crop coverage.
Nozzle selection: Hollow cone brass nozzles with a D-series orifice disc and core (whirlplate) are recommended. Nozzles should point straight down or slightly backward.
Swath width: For most field and vegetable crops, swaths just beyond the wingspan of 11 to 12 meters for light aircraft and up to 14 meters for heavier aircraft are suggested. Optimum swath for helicopters is usually 1.5 to 3 meters beyond normal boom length.
Altitude: For most crops, the spray boom should be positioned 1.5 to 3 meters above the crop canopy.
Flagging: Swaths should be marked at the end of the field with permanent flags. Do not use human flaggers. Swaths should be measured accurately with a chain or other device except when rows can be accurately counted.
