Two insecticides, carbaryl and chlorpyrifos, were evaluated at low concentrations as tracers to predict the behaviour of spray clouds of malathion at field strength. Aerial sprays were produced from a Cessna Ag Husky equipped with a dual liquid dispersal system, spraying simultaneously. Spray drift was measured at 90 or 30 m downwind using 1.6 mm polyester cord and 0.6 mm monofilament line suspended from a helium-filled blimp tethered 15.25 m above ground level. Recoveries of malathion averaged 87.3% and 85.2% of the amount predicted from the tracers on the monofilament and polyester, respectively. The coefficients of variation for 12 flights were 50.9% for the monofilament line, and 17.4% for the polyester cord. |
