Chemical control of Helicoverpa armigera (Hübner) in Chick pea

Sandeep Sharma, Nanda Khandwe, K. K. Nema

Abstract

Application of rynaxypyr 20 SC @ 75 ml/ha was found to be the most effective in reducing the larval population, pod damage and fetched highest grain yield. Although, rynaxypyr gave the highest net returns but the ICBR of flubendiamide 48 SV @ 50 ml/ha was higher than rynaxypyr. Rynaxypyr 20 SC @ 75 ml/ha or flubendiamide 48 SC @ 50 ml/ha could be an effective and economical towards management of Helicoverpa armigera in chick pea.
