药剂处理对重茬山药病害的防治效果
Control Effects of Chemical Treatment on Diseases of Continuous Cropping Yam
摘要
Abstract
Japan Dahechangyu was used as experimental material to study the control effects of chemical treatment on diseases of continuous cropping yam by the location experiment in field.The results showed that the disease indexes of yam root -knot nematode disease,anthracnose and brown blotch increased yearly with the increase of continuous cropping years,while the commodity rate decreased year by year.Chemical treat-ment could increase the control effect and yam quality and decrease the disease indexes of three main diseases. The optimal chemical treatment was to soak the seeds with 500 times 70% thiophanate methyl for 1 0 minutes, broadcast 8 kg of strong root agent per 666.7m2 after sowed,spray 0.4 kg of 30% hymexazol per 666.7m2 , and irrigate the root with 2 L of 0.3% sophora flavescens alkali per 666.7m2 .关键词
