摘要
为筛选出有效防治燕麦蚜虫的生物药剂及施药方式,开展不同生物药剂及施药方式对燕麦蚜虫的田间防治效果测定。结果表明,叶面喷施0.3%印楝素乳油对燕麦蚜虫的防效最好,药后14d的防效为76.82%,高于化学药剂5%吡虫啉乳油的防效(75.98%);药后14d,绿僵菌土壤施药+白僵菌叶面喷施、白僵菌土壤施药+白僵菌叶面喷施对燕麦蚜虫的防效较好,分别为79.65%、76.12%,均高于其他施药方式。建议在蚜虫初发期选择0.3%印楝素乳油替代化学药剂防治燕麦蚜虫,亦可选择在白僵菌、绿僵菌土壤施药的基础上叶面喷施白僵菌防治燕麦蚜虫,均有较好的防治效果。
In order to screen out the best biological agents and application methods for controlling oat aphids,the effects of different biological agents and application methods on field control of oat aphids were measured.The results showed that 0.3% azadirachin emulsion sprayed on the leaves had the best control effect on aphid.The control effect was 76.82% after 14 days,which was higher than that of 5% imidacloprid emulsion(75.98%).14 days after application,soil application of Metarhizium anisopliae+Beauveria anisopliae foliar spray,soil application of Beauverhizium anisopliae+Beauveria anisopliae foliar spray had better control effect on oat aphids,79.65% and 76.12%,respectively,which were higher than other application methods.It is suggested to choose 0.3% azadirachtin emulsion instead of chemical agents to control oat aphids at the initial stage of aphids emergence.It is also possible to apply Beauveria bassiana and Metarhizium anisopliae in soil on the basis of spraying Beauverhizium bassiana on leaf surface to control oat aphids,which has better control effect.
