捕杀特·黄板对大棚番茄桃蚜及蚜传病毒病的防治效果

摘要

Bushate yellow-board was involved in the tomato greenhouse efficacy trials to analyze its control effect on the Myzus persicae and the decline rate of the aphid- borne virus diseases. Single fac tor analysis showed that the yellow- board hanging for 7 days had the same efficacy with the CK fungi cide and hanging for 21 days had 1％ significance of difference better than CK fungicide, control effica cy of Bushate yellow-board to attract and prevent aphid reached 96. 13％. The study found that the Bushate yellow- board can significantly reduce the disease index of cucumber mosaic virus (CMV) in tomato.%通过捕杀特·黄板在大棚番茄上的药效试验,分析捕杀特·黄板对桃蚜的防治效果及其对蚜传病毒病CMV的减退率.单因素分析结果表明,捕杀特·黄板具有较好的持效杀虫性,悬挂14 d和对照药剂的防治效果差异不显著,21 d后治蚜效果优于对照药剂,防治效果达96.13%,且差异显著性水平为0.01.调查研究发现,捕杀特·黄板的使用可明显降低大棚番茄CMV的病情指数.
