Field efficacy of cyclobutrifluram 50％FS against sweet potato stem nematode Disease
[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.
