Chemical Control of Coneworm, <I>Dioryctria abietella</I> Denis and Schiffermueller (Lepidoptera: Pyralidae) in Seed Production Areas of Deodar (<I>Cedrus deodara</I>)

Abstract

Chemical control experiments were conducted against the coneworm, Dioryctria abietella by following the soil application of thimet 109 and furadan 3g, and tree injections of phosphomidon 85 sl and monocrotophos 36 ec at different dosages of treatments including control in seed production area of Deodar in Kansar Range of Chakrata Forest Division, Uttaranchal. The post treatment observations revealed a significant decline in the incidence of infestation in the case of drip line application in soil of thimet 109 @ 100 grams per 20 cm girth and tree injection of monocrotophos 36 ec @ 100 ml per 20-cm girth.
