摘要
[目的]明确50％三氟吡啶胺FS对甘薯茎线虫病的田间防治效果,为生产应用提供理论依据.[方法]以10％噻唑膦GR为对照药剂,采用田间小区试验,在河南省汝阳县柏树乡枣林村、城关镇张河村甘薯茎线虫病重发田进行田间药效试验.[结果]50％三氟吡啶胺FS对甘薯茎线虫病具有较好的防治效果,495～990 mL/hm2范围内防效达到79.9％～89.62％,显著优于10％噻唑膦GR 15 000 g/hm2的防效,从产量上看,2个处理挽回损失率达50.70％～81.32％.[结论]50％三氟吡啶胺FS495～990mL/hm2能够达到防治甘薯茎线虫病的目的,可结合田间病害发生情况选择不同剂量进行防治.
Abstract
[Aims]To clarify the field control effect of cyclobutrifluram 50％FS on sweet potato stem nematode disease and provide theoretical basis for the production application.[Methods]Field efficacy trials were conducted using field plot experiment with fosthiazate 10％GR as the control agent in severely affected fields by Ditylenchus destructor in Zaolin Village,Baishu Township,Ruyang County,Henan Province,and Zhanghe Village,Chengguan Town.[Results]Cyclobutrifluram 50％FS had good control effect on sweet potato stem nematode disease,with control efficacy of 79.9％-89.62％in the mass concentration range of 495-990 mL/ha,which is significantly better than that of thiazolidine 10％GR at 15 000 g/ha.From the perspective of production,the recovery loss rate reached 50.70％-81.32％.[Conclusions]Cyclobutrifluram 50％FS at 495-990 mL/ha can achieve the goal of controlling sweet potato stem nematode disease,and different doses should be selected for controlling it based on the conditions of field diseases.
