Abstract 4-granular insecticides viz., phorate 10 G, carbofuran 3G, cartap hydrochloride 4G and fipronil 0.3 G and 3spray formulations viz., monocrotophos 36 SL, chlorpyriphos 20 EC, dimethoate 30 EC and neem oil (crude) spary were tested against cashew stem and root borer (CSRB) for two consecutive years (2002 and 2003). Phorate was most effective and its persistence lasted for two months after application. Carbofuran was slightly better than cartap hydrochloride and fipronil. Among different sprayable Chlorpyriphos spray proved to be most effective to keep the trees pest free upto three months followed by Monocrotophos. Top |
