Abstract

Chemical control against overwintered adults of sunn pest Eurygaster integriceps Put. mostly has low efficacy. Today using insecticides and formulations that have durable toxicity on overwintered adults is more approved, because this strategy can reduce treated area against new generation. This research was conducted with six treatments and four replications in randomized complete block design against overwintered adults of sunn pest in Qazvin (Ismail Abad Agricultural Research Station) at 2007-2008. Emulsions and micro capsules formulations were applied with using motorized knapsack atomizer sprayer and with hands respectively. The treatments included delthametrin EC 2.5%, fenitrothion EC50%, fenitrothion G 5%, fenitrothion CS 20%, fipronil G 0.2% and check, that their effectiveness in controlling on sunn pest adults, new generation adults and nymphs were studied. The delthametrin EC 2.5% was more effective than the other treatments. Most treatments were not able to reduce damaged in the standard level (2%). Thus applying of pyrethroid insecticides such as delthametrin with micro capsulated suspension (CS) formulation can be more affected in chemical control of overwintered adults.
