防治南美斑潜蝇药效试验

Experiments on Control Effects of Liriomyza huidobrensis (Blanchard) with Chemicals

摘要: 为筛选防治南美斑潜蝇效果较好的药剂,在该虫始发期设置了6种药剂的药效试验。结果表明:施药后9d各药剂防效由高至低依次为:50%"蝇蛆净"1000倍液、98%"巴丹"1000倍液、2.5%"功夫"2000倍液、1.8%"阿巴丁"3000倍液、1.8%"害极灭"2000倍液和40%"绿菜宝"1000倍液,6种药剂的相对防效分别为80.91%、78.79%、76.84%、76.18%、74.39%和72.27%。经方差分析,6种杀虫剂对南美斑潜蝇的防治效果达极显著水平,经LSR法检验,药剂间差异不显著。

Abstract: In order to select more effective chemicals to control Liriomyza huidobrensis (Blanchard), 6 kinds of chemicals were applied in its starting stage.The experiment results showed that the chemicals in order of control effects were 50% Neprex at a dilution of 1000 > 98% Padan at a dilution of 1000 > 2.5% Kungfu at a dilution of 2000 > 1.8% Abametin at a dilution of 3000 > 1.8% Agrimec at a dilution of 2000 > 40% Lucaibao at a dilution of 1000, and the relative control effects of the 6 chemicals were 80.91%, 78.79%, 76.84%, 76.18%, 74.39% and 72.27%, respectively.There were extremely significant differences among control effects of the 6 chemicals by variance analysis, and no significant differences among the 6 chemicals by LSR test.
