Abstract

In field experiments in Andhra Pradesh, India, in 1990-91, chickpeas were treated with quinalphos formulated as a dust (1.5% at 25 kg/ha), an emulsifiable concentrate (EC 20 at 20 litres/ha) or as an acquaflow (AF 20 at 20 litres/ha). The effects on small and large larvae of Helicoverpa armigera were considered. After 72 h, the 3 formulations had reduced the numbers of small larvae per plant from 8.4, 8.0 and 8.9 to 0.2, 1.8 and 1.4, resp., and the numbers of large larvae from 1.5, 1.4 and 1.4 to 0.8, 0.5 and 0.5, resp. It is commented that the AF formulation was more convenient to prepare than the emulsifiable concentrate.
