Abstract

Population dynamics of Helicoverpa armigera (Hubner) and Trichoplusia orichalcea infesting Egyptian clover showed peak population of H. armigera on April 30 in var. BL-10 and T. orichalcea on April 9 in var. BL-42. The bioefficacy of reduced risk insecticides viz., chlorantraniliprole 18.5 SL @ 125 ml/ha and flubendiamide 480 SC @ 100 ml/ha significantly reduced T. orichalcea and H. armigera at 2nd and 7th days of spray and recorded higher seed yield.
