Abstract

In field trials in Andhra Pradesh, India, in 1992-93, various insecticides were tested for control of Helicoverpa armigera on chickpeas. By 5 and 14 days after application, acephate (75 SP, 1 kg/ha) alone, cypermethrin (10 EC, 1 litre/ha) alone, quinalphos (25 EC, 2 litres/ha) alone, acephate (0.25 kg/ha) + cypermethrin (0.75 litre/ha) and acephate (0.25 kg/ha) + quinalphos (1.5 litre/ha) had reduced the pest population from 4.2, 4.5, 3.6, 5.0 and 3.8 larvae/plant, resp., to 0.4 and 0.4, 1.4 and 1.1, 1.0 and 1.2, 1.2 and 0.4, and 1.0 and 0.4 larvae/plant, resp. It is concluded that acephate + cypermethrin was the most economical treatment.
