ABSTRACT

Out of four IPM modules evaluated against cotton bollworms viz., spotted bollworm Earias
vittella Fab., American bollworm Helicoverpa armigera Hubn. and pink bollworm Pectinophora
gossypiella (Saunders), the IPM module (M2) comprising seed treatment with imidacloprid @
7.5g/kg,, release of Trichogramma chilonis @ 1.5lakhs/ha at 60 and 67DAG (days after
germination), application of NSKE (5%) at 40 and 55DAG , spraying of endosulfan (0.05%) at
75DAG and profenophos (0.05%) at 90DAG on need basis ,growing of cowpea as inter crop and
installing of bird perches @20/ha afforded excellent control of bollworms with highest seed
cotton yield of 15.65q/ha and monetary benefit of Rs. 9904/- per ha , over the chemical
control schedule (M4).
