Abstract
To screen for the prevention and cure of rice leaf-roller effective agent and using dose,different dosages of 3%avermectins EW were chose on the field test.The test results showed that the leaf protection effect of 3%avermectins EW treatment dose 450 mL/hm2 was 87.80%,and had no significant difference on control effect of contrast agent 1.8%avermectins EC 525 mL/hm2(84.51%)(P>0.5),and they were significantly higher than 3%avermectins EW 300 mL/hm2,3%avermectins EW 150 mL/hm2 and contrast agent 48%chlorpyrifos EC 1 200 mL/hm2(P<0.5).Insecticidal effect of 3%avermectins EW treatment dose 450 mL/hm2 was 92.48%,and had no significant difference on 3%avermectins EW 300 mL/hm2,contrast agent 1.8%avermectins EC 300 mL/hm2 and 48%chlorpyrifos EC 1 200 mL/hm2(P>0.5),but had significant difference with 3%avermectins EW 150 mL/hm2(P<0.5).Tested agents were safety on rice and paddy field.According to the field insect quantity,in the rice leaf-roller egg hatching peak,using 3%avermectins EW 300~450 mL/hm2(effective avermectins ingredient 9.0~13.5 g/hm2)could well control rice leaf-roller harm.关键词
