  Applications

Pirimiphos-methyl is a broad-spectrum organophosphorus insecticide and acaricide, with both contact and fumigant action. In plants, it penetrates leaf tissue and exhibits translaminar action but is of short persistence. When applied to stored agricultural commodities (such as grain and nuts) or to the fabric of buildings, it provides longer-lasting pest control. It is also effective for space treatment and as a mosquito larvicide. Pirimiphos-methyl is used for controlling a wide range of chewing, sucking and boring insects and mites in warehouses, stored grain, animal houses, domestic and industrial premises; various mites on vegetables, ornamentals, bulb flowers, sugar cane, maize, sorghum, rice, citrus and other fruit, olives, vines, alfalfa, cereals; and for controlling certain glasshouse pests (especially whiteflies, thrips, mealybugs, aphids, and mites).
