扑虱灵是一种抑制昆虫生长发育的新型选择性杀虫剂,对半翅目飞虱、叶蝉等害虫有良好的防治效果。据南京金陵石化公司化工二厂介绍,加入 WPA-9025助剂后的扑虱灵更能显示其优良的杀虫效果。作者通过对稻飞虱室内生测试验,筛选出高效、经济的样品,进行了田间小区试验,从而明确了扑虱灵加 WPA-9025助剂能够降低用药量,提高防效。
Puracetam is a new type of selective insecticide that inhibits the growth and development of insects and has good control effects on pests such as Hemiptera, planthoppers and leafhoppers. According to Nanjing Chemical Plant Plant Jinling Petrochemical Company introduced WPA-9025 additives added after the parasitemia better show its excellent insecticidal effect. Through the indoor test of the planthoppers, the author screened the samples with high efficiency and economy, and conducted the plot test in the field so as to make it clear that the methotrexate plus WPA-9025 additive can reduce the dosage and improve the control effect.
