Abstract
The present study was conducted to evaluate the comparative efficacy of different insecticidal treatments against tur pod fly [Melanagromyza obtusa (Malloch)], tur pod bug (Clavigralla gibbosa Spinola) and pod borer [Helicoverpa armigera (Hübner)] infesting pigeonpea variety Bahar during Kharif 2015-16 and 2016-17. Among all the treatment modules, Module 5 with sequential application of Chlorantraniliprole 18.5 SC @ 30g a.i/ha - Indoxacarb 15.8 EC @ 73g a.i./ha - Acetamiprid 20 SP @ 20g a.i/ha and Module 3 with sequential application of Chlorantraniliprole 18.5 SC @ 30g a.i/ha - Acephate 75 SP @ 750g a.i/ha - Acephate 75 SP @ 750g a.i/ha provided better control of M. obtusa, C. gibbosa and H. armigera on pigeonpea in terms of lower pod and grain damage and higher grain yield. Hence, these two treatment modules can be suggested to the farmers for effective management of pod borers and pod bug on long duration pigeonpea.
