Abstract

Field efficacy trials indicated 220 g/L CypermethrinChlorpyrifos EC had a good effect on controlling the wheat aphid.Pest preventing efficiency grow with dose increaseing,the treatment of 50 mL/667m 2 with a efficiency up to 92.4%,90.8% when 3 days and 7 days after pesticide spraying,respectively,which was significantly better than 10% Cypermethrin EC,but had no significant difference with 40% Chlorpyrifos EC.And pest controlling efficiency still stayed in a high level after 14 days,which was significantly better than 10% Cypermethrin EC and 40% Chlorpyrifos EC.Moreover,220 g/L CypermethrinChlorpyrifos EC 50 mL/667m 2 was quickacting, safe,and had long residual activity.A regional application could be developed.
