Control of Asparagus caterpillar by Applying Several Low-toxic Pesticides

田间试验结果表明,10%赛虫特可湿性粉剂450g/hm2和15%及杀乳油450g/hm2对甜菜夜蛾防治效果较好,防效分别为74.6%～98.1%和51.0%～91.2%,显著高于4.5%高效氯氰菊酯可湿性粉剂450g/hm2,防效37.0%～49.6%,4%吡高乳油225g/hm2,防效19.8%～24.4%,16000IU/μL苏云金杆菌悬浮剂750g/hm2,防效0.16%～66.6%。

The field control showed that the effects of applying 10% cypermethrin WP （450 g/ha） and 15% abamectinphoxim EC （450 g/ha） were higher than those of applying 4.5% cypermethrin WP （450 g/ha）, the control results were from 74.6% to 98.1% or 51.0% to 91.2%, but the latter was 37.0%-49.6%, and the effects of applying 4% Bigao EC （225 g/ha） and 16000IU/μL Bacillus thuringiensis suspension agent （750 g/ha） were from 19.8% to 24.4% and 0.16% to 66.6%, respectively.
