oa Journal of the Entomological Society of Southern Africa - The choice of insecticides for destroying Red. Locusts in their outbreak areas

Abstract

In spraying insecticides, it used to be the practice to apply very large volumes of material at low concentrations. In orchards for example, the liquid would be applied until it ran off all affected surfaces, so that only the concentration of the insecticide had to be specified. The time taken and the expense involved in carting and dispersing hundreds of gallons of liquid per acre is resulting in attempts at control of insects with low-volume instead of this high-volume spraying.
