Abstract
Asymethrin (Chinmix 5 EC) was compared during 1988 and 1989 at 10, 12.5, 15 and 20 g aljha with fenvalerate, cypermethrin (50g ai/ha) and deltamethrin (10g ai/ha) for bollworm control. Asymethrin at 12.5g ai/ha was as effective as other syntherlc pyrethroids for boll worm control. The boll and loculi damage were Inversely related with yield of seed cotton.
