| 摘 要： | 以Bt-15A3烟雾剂采用3WF-2.6型背负式喷雾喷粉机进行超低量喷雾,对小菜蛾进行田间药效试验。结果表明:Bt-15A3烟雾剂的供试剂量为1312.5mL/hm2和1575mL/hm2时对幼虫有较理想的防效,防效分别达到83.56%和90.07%。对于世代重叠严重的田块,应在药后7d进行补施,以达到彻底控制小菜蛾危害的目的。

| Abstract: | By field trials of spraying Bacillus thuringiensis 15A3 smoke agents with 3WF-2.6 sprayer on Plutella xylostella,the results show that the field efficacy of Bt-15A3 smoke agents is desirable.On the larva,the corrected controlling ratio of smoke agent could reach 83.56% and 90.07%,respectively by the dose of 1 312.5 mL/hm2 and 1 575 mL/hm2.So,it is suggested that the supplement should be carried out after spraying the agents for seven days on the fields existing severe reduplicated generation in order to control the Plutella xylostella completely. |
