摘要
甘薯腐烂茎线虫病是甘薯上的主要病害。为筛选出有效药剂,2015～2016年田间试验了7种药剂穴施对甘薯腐烂茎线虫的防治效果及其对甘薯成活率和产量的影响。结果表明,30%辛硫磷微囊悬浮剂、5%辛硫磷颗粒剂、30%三唑磷微囊悬浮剂和10%噻唑磷颗粒剂对甘薯腐烂茎线虫有很好的防治效果。其中30%辛硫磷微囊悬浮剂、30%三唑磷微囊悬浮剂不仅对甘薯的存活率和生长无不良影响,而且增产效果相对较高,可作为防治甘薯腐烂茎线虫病的主推药剂。
Sweet potato rotten stem nematode disease is main disease on sweet potato.The efficacy of seven pesticides to the disease ,and the influence of these pesticides on the survival and yield of sweet potato were evaluated in field from 2015 to 2016.The results showed that the 30% phoxim CS,5% phoxim GR,30% triazophos CS,and 10%fosthiazate GR had excellent control effect on the nematode. Furthermore,the application of 30% phoxim CS and 30% triazophos CS had no negative impact on survival and growth of sweet potato,and had positive influence on increasing the yield.Both of the pesticides is recommended for controlling the sweet potato rotten stem nematode.
