Evaluate newer insecticides along with biopesticides against mango leaf webber, Orthaga spp.

Abstract

Studies on mango leaf webber, Orthaga spp. with special reference to seasonal incidence, biology and management” was conducted during the year 2015-16 and 2016-17at the Horticultural orchard of BTC College of Agriculture and Research Station, Bilaspur (C.G). Newer insecticides along with biopesticide and mechanical method were evaluated against mango leaf webber (Orthaga spp) and minimum larval population (12.53 larvae/ tree) was recorded under mechanically destruction of webs. The second best effective treatment was application of Clorantranilliprole 18.5% SC (21.21 larvae/tree) followed by Flubendiamide 39.5% SC (21.65 larvae/tree) and Indoxacarb 14.5% SC (23.08 larvae/tree). Application of Bacillus thuringiensis 5% WP had resulted the highest larval population of 31.00 larvae/tree found as least effective in reducing the leaf webber population.
