GENERAL INFORMATION


MODE OF ACTION
The active ingredient in Quash SC is metconazole, a broad-spectrum triazole fungicide that works by inhibiting demethylation and other processes in sterol biosynthesis. Quash SC is systemic and is quickly absorbed into plant tissue. Metconazole is absorbed quickly into the plant tissue and can move up, but not down, in the plant. Metconazole has no effect on fungal spore germination, but interferes with other early developmental processes in the life cycle of certain fungi. Although Quash SC cannot prevent spore germination, it prevents spore formation and inhibits mycelial growth.
Quash SC is most effective when applied prior to infection. Optimal disease control is achieved when Quash SC is applied in a regularly scheduled spray program and used in combination and/or rotation with other effective fungicides that have different modes of action (i.e., non-Group 3 fungicides). Quash SC is a sterol biosynthesis inhibitor; avoid rotating with other sterol biosynthesis inhibitors.

MIXING INSTRUCTIONS
1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water.
2. While agitating, slowly add the Quash SC to the spray tank. Agitation should create a rippling or rolling action on the water surface.
3. If tank mixing Quash SC with other labeled pesticides, add water soluble packets first, followed by dry formulations, flowables, emulsifiable concentrates and then solutions.
4. Add any required adjuvants.
5. Fill spray tank to desired level with water. Agitation should continue until all spray solution has been applied.
6. Mix only the amount of spray solution that can be applied the day of mixing. Apply Quash SC within 24 hours of mixing.

SPRAY VOLUME
Apply Quash SC in sufficient water to ensure thorough coverage of foliage, blossoms, and fruit. Thorough coverage is required for optimal disease control. For ground application, apply a minimum of 200 L of spray mixture per hectare. For aerial application, apply a minimum of 50 L of spray mixture per hectare to ensure uniform coverage.

AERIAL APPLICATION
To minimize drift, apply the largest droplet size consistent with uniform coverage and satisfactory disease control. To obtain satisfactory application and avoid drift, the following directions must be observed:
 Do not apply during low-level inversion conditions, when winds are gusty or under other conditions that favour drift. Do not spray when wind velocity is less than 3 km/h or more than 16 km/h.
 Carrier Volume and Spray Pressure: Application at less than 50 litres per hectare may provide inadequate coverage and control. The higher litreage applications generally afford more consistent disease control. Do not exceed the nozzle manufacturer’s recommended pressures. For many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
 Nozzle Selection and Orientation: Formation of very small drops may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible and by avoiding excessive spray pressure. Use nozzles that produce flat fan or cone spray patterns. Use non-drip type nozzles, such as diaphragm type nozzles, to avoid unwanted discharge of spray solution. The nozzles must be directed toward the rear of the aircraft, producing a spray discharge at an angle between 0 and 15° downward. Do not place nozzles on the outer 25% of the wings or rotors.
 Adjuvants and Drift Control Additives: Refer to tank mix partner’s label for adjuvant recommendation. Drift control additives may be used although it is better to obtain coarser sprays through appropriate nozzle selection and use wherever possible.
When a drift control additive is used, read and carefully observe the cautionary statements and all other information appearing on the additive label, and be certain of compatibility with the tank mix and nozzle types being used before selecting any adjuvant types.
