Abstract
The bio-efficacy of cypermethrin, dichlorvos, endosulfan, profenophos and quinalphos were evaluated against Spodoptera litura infesting soybean cv. DS-228 (Phule Kalyani). The soybean was sprayed twice with respective insecticides at three week intervals starting from 35 days after germination. The pooled data showed that all the insecticidal treatments were significantly superior over untreated control in reducing the larval damage. The treatment with profenofhos 0.1% gave maximum protection when recorded up to 7 days after application and reported 6.5% foliage damage. The highest residual toxicity to tobacco caterpillar recorded at 24, 48, 72 hrs and one week after application was exhibited in the treatment of profenofhos 0.1% under laboratory to field weathered deposits. Among the different insecticidal treatments tested in field, profenofhos 0.1% alone showed significantly superiority in controlling larval population and thereby, reduction in leaf damage and increasing the grain yield.
