Field Efficacy Evaluation of Different Fungicides against Sweet Potato Stem Nematode Disease
摘要
Abstract
In order to clarify the field control effects of different pesticides and their combination with microbial agents on sweet potato stem nematode disease.This article used fosthiazate 10％GR as a control and conducted field efficacy testing in Zhanghe Village,Chengguan Town,Ruyang County,Henan Province,using a community trial.The results showed that all the treatments were safe to the growth of sweet potato seedlings.The control effects of fluopyram 41.7％SC,cyclobutrifluram 50％FS,metalaxyl-M hymexazol 30％AS+fosthiazate 10％GR were more than 80％.Treatment with trichoderma harzianum WP(actual effective viable bacterial count≥1 billion·g-1)+fosthiazate 10％GR and bacillus subtilis WP(actual effective viable bacterial count ≥20 billion·g-1)+fosthiazate 10％GR had better control effects,reaching 92.11％and 90.07％respectively.The above-mentioned medicament and combination could obviously recover the yield loss of sweet potato,and the recovery rate was over 43％.The above fungicides and combinations can provide reference basis and implementation scheme for the control of sweet potato stem nematode disease in the field.关键词
