摘要: 为研究不同药剂对紫甘薯茎线虫病的防治效果,分别于2013、2014年,采用大田试验种植‘济黑薯1号’和‘南紫薯014’,比较30%辛硫磷微胶囊悬浮剂、5%涕灭威颗粒剂和5%特丁硫磷颗粒剂防治紫薯茎线虫病的效果。结果表明,从病薯数、病薯率、病情指数和鲜薯产量等方面综合评价,施用30%的辛硫磷微胶囊悬浮剂7.5 mL/m2,可以达到控制紫薯茎线虫病的最佳效果,且辛硫磷符合绿色农业发展需求,具有推广应用的价值。

Abstract: In order to research the effects of different medicaments under field conditions on ‘Jiheishu 1’ and ‘Nanzi 014’ in 2013 and 2014, the authors compared the control effects of 30% phoxim capsule, 5% aldicarb granules and 5% terbufos granules. The results showed that from a comprehensive assessment of the diseased tuber number, the rate of disease, the disease index and fresh root yield, applying 30% phoxim capsule 7.5 mL/m2 had the best control effect on the stem-nematodes disease, in addition, phoxim capsule accorded with green agriculture, thus, it had certain values of popularization and application.
