Abstract

In a field experiment in 1995-96 in Andhra Pradesh with chickpeas, the control of Helicoverpa armigera with Spark (deltamethrin 1% + triazophos 35%), Polytrin-C (cypermethrin 4% + profenofos 40%), cypermethrin, Delfin WG (bioinsecticide made with Bacillus thuringiensis) or cypermethrin + Delfin WG was evaluated. The most effective treatments were Spark and Polytrin-C. Cypermethrin, with and without the bioinsecticide, was ineffective.
