摘要
为科学筛选适宜的草原蝗虫防治药物和施药浓度,本试验比较了 3种不同药剂、不同施药浓度对草原蝗虫的防治效果.结果表明:试验区蝗虫混合虫口密度约为15头/m2,3种药剂对草原蝗虫均有较好的防治效果,其中,4.5％高效氯氰菊酯起效最快,施药3d后其防治效果就达到90％以上,但是7 d后,300 mL/hm2的1.8％阿维菌素和750 mL/hm2的1.3％苦参碱两个剂量的防治效果与600 mL/hm2的4.5％高效氯氰菊酯的防治效果差异不显著(P＞0.05).为保证防治效果和生态安全性,建议在一般防治中使用苦参碱和阿维菌素,推荐使用剂量为750 mL/hm2和300 mL/hm2,在危害严重时使用高效氯氰菊酯,推荐使用剂量为 600 mL/hm2.
Abstract
In order to screen the suitable control drugs and spraying concentration of grassland grasshopper,the control effect of 3 different agents with different spraying concentration on grassland grasshopper was compared in this experiment.The results showed that:The mixed population density of grassland grasshopper in the test area was about 15 heads/m2,and the three agents had good control effect on grassland grasshopper.Among them,4.5％cypermethrin had the fastest effect,and the control effect reached more than 90％after 3d application.The control effect of 1.8％abamectin at 300 mL/hm2 and 1.3％matrine at 750 mL/hm2 was not significantly different from that of 4.5％cypermethrin at 600ml/hm2(P＞0.05).In order to ensure the control effect and ecological safety,it is recommended to use matrine and avermectin in general control,the recommended dosage is 750 mL/hm2 and 300 mL/hm2,and the recommended dosage is 600ml/hm2 when the harm is serious.
