不同杀虫剂防治豌豆彩潜蝇田间效果比较试验

选用5%阿维菌素(爱福丁)乳油800倍液、2.4%阿维.高氯可湿性粉剂、1%甲氨基阿维菌素苯甲酸盐乳油1 500倍液、20%斑潜净乳油1 500倍液,以清水为对照对豌豆彩潜蝇进行了田间药效防治试验。结果表明:2.4%阿维.高氯防治效果最好,施药后10 d的防效达89.0%;1%甲氨基阿维菌素苯甲酸盐乳油1 500倍液防治效果最差,施药后10 d的防效仅达72.6%。方差分析结果表明,施药后10 d在0.05水平上各处理间差异显著(F=3.714,P=0.042<0.05),2.4%阿维.高氯与1%甲氨基阿维菌素苯甲酸盐1 500倍液存在显著性差异,其余处理间差异均不显著。

Field Tests of Different Kinds of Pesticides for Controlling on Chromatomyia horticola Goureau of Pea

The control effects of pesticides,using 5% abamectin(Aifuding)EC 800 times,2.4% Avermectin · WP high chloride,1% methylamino Avermectin benzoate EC 1 500 times,20% of net spot potential EC 1 500 times,with water as a control on Chromatomyia horticola Goureau of vegetables in pea were investigated.The results showed that the control efficiency of 2.4% Avermectin · WP high chloride was the highest with control effect came to 89.0%,and 1% methylamino Avermectin benzoate EC 1 500 times was the lowest with control effect came to 72.6%.Results of analysis of variance showed that after 10 days a significant diference existed between 2.4% Avermectin · WP high chloride and 1% methylamino Avermectin benzoate EC 1 500 times(F=3.714,P<0.05),the rest were no significant differences between treatments.
