Product Dose

Pesti Mala ULV 96 can be effectively applied with conventional aircraft spray equipment by making a few minor modifications to the plumbing and boom assembly.

PUMP

Pumps capable of producing pressures of 275-350 kPa will be satisfactory. A bleed line, at least 5 mm in diameter should be installed on the high point of the impeller chamber to release trapped air. This line should bleed back to the top of the tank above the liquid level.

BY-PASS

A by-pass is required from the spray pump outlet to the spray pump inlet. This line must be equal in diameter to the pump outlet and should contain a valve controllable from the cockpit that will permit adjustments of boom pressure in flight. The by-pass commonly used to recirculate MALATHION 95 ULV to the spray tank must be closed to avoid aeration of the insecticide.

BOOM AND NOZZLE PLACEMENT

The distance between the left and right outboard nozzles should be at least 3/4 of the wing span. The total number of nozzles used should be equally spaced across this span if the aircraft is flown at six metres or higher. Trailing edge booms are desirable and the nozzles should be placed on the boom where pilot can readily see them to check for plugging during spray operation. A bleed line at least 5 mm in diameter should be attached to the outer end of each boom and routed back to the top of the spray tank but above the liquid level. This line will bleed off pressure and prevent sharp cut-off. If a nozzle is placed at each end of boom, as many Ag Cat spray booms are assembled, this bleed line is not necessary.

NOZZLES

Use at least 4 to 6 flat fan nozzles, such as Spraying Systems 8001, 80015, or 8002 for small aircraft, such as Piper Pawnees and Stearmans. For aircraft operating at 240 km/h or faster, use 10 to 14 of the 8010 or 8015 flat fan nozzles. Nozzles should be pointed straight downward on small aircraft and straight back for faster aircraft. Use 100 mesh screens with 8001, 80015 and 8002 nozzles. Diaphragm check valves should be used on each nozzle to insure positive cut-off of spray during flight. Do not use cone nozzles. Rotary atomizers, commonly known as Mini-Spin nozzles, developed by the Plant Pest Control Division, can be substituted for the flat fan nozzles. Use the same flat nozzle tips as mentioned above when using the Mini-Spin nozzles.

MOSQUITO AND FLY CONTROL

Pesticide Mala ULV 96 Ultra Low Volume Aerial Application where Automobiles, Trailers, Trucks are present. Aerial spraying should not be attempted when the wind is at or above 15 km/h or temperature is above 27°C. Undiluted spray droplets of Pesticide Mala ULV 96 will permanently damage vehicle paint finishes unless the fixed wing aircraft used for the ultra low volume application meets all of the specifications listed below:
 

• Aircraft is operated at 240 km/h or more.
•  There are no leaks in the ultra volume low spray system.
• Nozzles are placed on the boom at a 45° angle down and into the wind.
• Diaphragm check valves are used on all nozzles to insure positive cut-off
  of the spray.
• Dosage of Pesticide Mala ULV 96 does not exceed 200 mL/ha when spraying where vehicles are present.
• The spray system produces droplets of this product in the 50 to 60 mass median diameter (MMD) micron range, with no more than 10% of the droplets exceeding 100 microns, as determined be readings made from microscope slides coated with Dri-Film. For information on determination of droplet size, request additional data from United Agri Products.
• Use recommendations: Adult mosquitoes, Houseflies, stable flies in feedlots, stabling areas and
  pastures. 425 - 550 mL/ha

IN RESIDENTIAL AREAS, RATES MUST NOT EXCEED 260 g a.i./ha (i.e. 274 mL product/ha).

Residential areas are defined as sites where bystanders including children may be potentially exposed during or after spraying. This includes around homes, schools, parks, playgrounds, playing fields, public buildings or any other areas where the general public including children could be exposed. Consult Provincial/Territorial pesticide regulatory officials for required authorization.
