Insecticides are important components of Integrated Pest Management of cotton. In the present studies new class of chemicals, insect growth regulators (IGR) were evaluated against Helicoverpa of cotton at MCRS, G.A.U., Surat in Gujarat. Three different insect growth regulators, viz., Cascade 10 DS (Flufenoxuron), Match (Lufenuron) 5% EC and Rimon (Novaluron) 10% EC were evaluated against Helicoverpa under field conditions during 1998-99 and 1999-2000 and were comparable with the recommended insecticide Endosulfan. Rimon 10 EC @ 100 g ai/ha and Cascade 10 DS @ 100 g ai/ha insect growth regulators showed significantly higher efficacy in controlling larval population, maximum deformity in larva, bollworm damage to squares, bolls and locules of Helicoverpa. Similarly, least adverse effect of all these IGRs on eggs, larvae and adults of Chrysoperla, Lady Bird Beetles and Rogas spp. were also observed. The maximum seed cotton yield was (2254 kg/h) harvested from the plots treated with Rimon 10 EC @ 100 g ai/ha followed by Cascade @ 100 g ai/ha (1935 kg/ha), Match @ 60 g ai/ha (1882 kg/ha) and Rimon @ 75 g ai/ha (1865 kg/ha) as compared to 1824 kg/ha in standard check and 1204 kg/ha in untreated control.
