Abstract

The control effects of six middle and low toxic pesticides on the adult of rice water weevil were studied.The results showed that the control effects of 5% esfenvlerate EC 375 mL/hm2,200 g/L chlorantraniliprole 150 mL/hm2,40% chlorpyrifos EC 900 mL/hm2,20%profenofos EC 3 600 mL/hm2 and 20% phoxim+triazophos EC 950 mL/hm2 were the better.Among these,200 g/L chlorantraniliprole EC,40% chlorpyrifos EC and 20% phoxim+triazophos EC could be used to replace the highly toxic pesticide.Although the effect of 20%profenofos EC was better,the dosage and cost were higher,which could be used alternatively.
