Pest Management in Greengram (Vigna radiata L.) Grown Under Agroforestry

Abstract

The pests of green gram (Vigna radiata L) var. CO 6 and their management with insecticides on the crop grown under neem trees was compared with a sole crop of green gram. Carbofuran granules applied to the soil effected better protection against the early stage pests of greengram until forty five days after which the population of aphids declined on the sole crop while on the intercrop the incidence was reduced even earlier in the carbofuran treated plots. Phosalone and Neem Seed Kernal Extract 10 per cent were equally effective in controlling defoliators on the intercropped green gram (80.55 and 68.57 per cent respectively) but varied in the sole crop. The grain yield was 90.32 per cent higher in the carbofuranl phosalone treated agroforestry plots compared to untreated check.
