摘要
5种农药对花生田蛴螬防治效果对比试验。结果显示:48%毒死蜱和40%比本胜施药后20 d校正虫口减退率依次为91.40%和82.51%,防效依次为95.66%和87.11%,比对照增产率分别为45.09%和33.72%,均高于40%辛硫磷乳油和40%甲基异柳磷乳油,而10%吡虫啉药后20 d校正虫口减退率、防效和增产率与48%毒死蜱和40%比本胜相当,建议在生产中推广应用。
The experiment was carried out to compare effect of five chemicals on controlling Holotrichia obeita in peanut field.Results showed that number of Holotrichia obeita in peanut field decreased by 91.40% and 82.51% 20 days of application of 48% Chlorpyrifos and 40% Bibensheng.The disease control effect was 95.66% and 87.11% and the yield of peanut increased by 45.09% and 33.72%.Effects were better than that of 40% Phoxim EC and 40% Isofenphos-methy.But effect of application of 10% Imidacloprid was the same as that of application of 48% Chlorpyrifos and 40% Benbisheng.
