Tank Mixing

Do not apply this product with any other additive, pesticide or fertilizer except as specifically recommended on this label.

DIRECTIONS FOR USE

READ ALL DIRECTIONS CAREFULLY BEFORE APPLYING. FAILURE TO FOLLOW LABEL INSTRUCTIONS MAY RESULT IN ERRATIC DISEASE CONTROL OR CROP DAMAGE.

PERSONAL PROTECTIVE EQUIPMENT
Applicators and other handlers must wear long-sleeved shirt and long pants, chemical resistant gloves and shoes plus socks.
Mixers and Loaders handling concentrated product, as an extra precaution, should wear coveralls, chemical resistant gloves, goggles, and rubber boots.

As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests. DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

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) coarse 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/h at the application site as measure outside of the treatment area on the upwind side.

DO NOT apply by air.

Application Guidelines
Apply Quintec Fungicide before visible symptoms of powdery mildew appear. Quintec Fungicide has no curative properties and will not control established infections of powdery mildew. Use sufficient water volume to ensure thorough coverage of all plant foliage. Disease control may be reduced at low spray volumes or if spray coverage is inadequate. If reliable predictive modeling (risk index) systems are available and indicate low disease pressure conditions, minimum label rates and longer application intervals may be used. Maximum label rates and short application intervals are recommended for severe or threatening disease conditions.
