甘薯茎线虫病的药剂防治研究

田间试验结果表明,30%辛硫磷微胶囊剂、三唑磷微胶囊剂、毒死蜱微胶囊剂、福气多(5%噻唑磷)4种不同药剂对甘薯茎线虫病均有较好的防治和增产效果。综合4个指标,考虑到实际生产上药剂使用方便、药效持续长等优点,初步筛选出福气多作为防治甘薯茎线虫病的首选药物。该药剂不仅防效较高,且病薯率低,商品薯率高,鲜薯产量位居第一,具有良好的应用前景。

Study on Insecticide Control of the Sweet Potato Stem-nematode Disease

The resuhs of field test indicated that four pesticides （30%Phoxim Microencapsules, Triazophos, Chlorpyrifos and Fuqiduo） had preferable effects on controlling stem-nematode disease and increasing yield of sweetpotato. According to control efficacy, Fuqiduo were more economic and suitable, and had great potentiality of application as biochemical pest-I cide with the benefit of high efficiency, low toxicity and pollution-free. It had great potential for the control of the stem-nematode disease in sweet potato.
