Abstract

Maruca vitrata (Geyer) is a major limitation in pigeonpea production. Keeping this point in view, the field experiments were undertaken on “Web-forming Lepidopteran, M. virtata (Geyer): An emerging and destructive pest in pigeonpea”. The experiment was conducted at Pulse Research Station, S. D. Agricultural University, Sardarkrushinagar during kharif 2013–14 and 2014–15 in randomized block design having three replications and seven treatments. Spays were given at 50% flowering stage and then at 15 days interval. The results showed that both in individual years as well as in pooled data, two sprays of chlorantraniliprole 18.5 SC @ 0.15 ml/l of water gave maximum control of pod borers (3.33%) with maximum grain yield (1817 kg/ha) but was at par with indoxacarb 15.8 EC @ 0.5 ml/l pod borers damage (3.83%) with a grain yield (1758 kg/ha).
