摘要
从病株率、病薯率、病情指数3个方面评价了8种供试药剂对甘薯茎线虫病的田间防治效果,其中,5%神农丹颗粒剂45 kg/hm2、10%福气多颗粒剂30 kg/hm2、22%吡虫.辛硫磷乳油9 L/hm2、35%辛硫磷微胶囊悬浮剂15 L/hm2和40%毒死蜱乳油15 L/hm2的防治效果较好,株防效为77.96%-89.83%,薯防效为85.30%-97.91%,病情指数防效为83.06%-98.94%。综合防治效果、药剂毒性、施用成本等因素,建议生产上施用22%吡虫.辛硫磷乳油9 L/hm2和35%辛硫磷微胶囊15 L/hm2防治甘薯茎线虫病。
The control effects of eight pesticides on stem-nematode disease of sweet potato under field experiment conditions were evaluated.The results showed that five pesticides（45kg/ha of 5% Shennongdan G,30kg/ha of 10% Fuqiduo G,9L/ha of 22% Imidacloprid·Phoxim EC,15L/ha of 35% Phoxim FL and 15L/ha of 40% Chlorpyrifos EC） had preferable controlling effects.The control efficacy was 77.96%-89.93%,85.30%-97.91% and 83.06%-98.94%,based on diseased plants,diseased tubers and disease index,respectively.According to control efficacy,toxicity and cost-effect,9L/ha of 22% Imidacloprid·Phoxim EC and 15L/ha of 35% Phoxim FL were more suitable to control stem-nematode disease of sweet potato in production.
