【摘要】 在番茄大田中进行了22.5%毒·高氯乳油防治美洲斑潜蝇药效试验,试验结果表明,22.5%毒·高氯乳油对美洲斑潜蝇防治效果较好,每667m2使用50mL和60mL处理,在施药后3d的防效分别为89.2%、92.4%,7d达到93.0%、95.1%,均显著高于对照药剂4.5%高效氯氰菊酯乳油和40%毒死蜱乳油的防效。更多还原

【Abstract】 Experiments on control of Liriomyza sativae Blanchard with 22.5% Chlorpyrifos + beta-cypermethrin EC were conducted in tomato field.Field trial results showed that 22.5% chlorpyrifos + beta-cypermethrin EC had the better effect on the controlling of Liriomyza sativae Blanchard.The control effect of 50 mL/667m2 to 60 mL/667m2 of 22.5% chlorpyrifos + beta-cypermethrin EC were 89.2% to 92.4% after application three days,then after application seven days it reached 93.0% to 95.1%,which were significant different from 4.5% beta-cypermethrin EC and 40% chlorpyrifos EC.更多还原
