Efficacy of new molecules against mango flower webber under high density planting systems

Abstract

Management of mango flower webber under high density planting system (HDPS) with newer molecules was conducted at the Regional Horticultural Research and Extension Centre, Dharwad, Karnataka during 2016-17. The results revealed that evaluation of new molecules against mango flower webber under HDPS revealed that two rounds of combination of profenophos 50 EC at 2.5 ml/l + azadirachtin 10000 ppm at 1.0 ml/l recorded lowest webber population (0.45 larvae /panicle), higher fruit yield (q /ha) and higher net returns Rs. 300555 with highest B: C ratio (5.26) as compared to the individual components and found to be economical in managing flower webber. Next best new molecules were flubendiamide, emamectin benzoate and lambda cyhalothrin. Generally, the combination of new molecules with azadirachtin could be deployed to combat the menace of flower webber more effectively in mango ecosystem.
