摘要
梨火疫病是我国近年来新发生的毁灭性细菌病害,我国无相关防控技术经验,急需筛选有效田间防治药剂.该研究通过在香梨初花期和落花期喷施杀菌剂,测定 12 种杀菌剂的 22 个制剂和 5 种药剂组成的 10种用药组合对梨火疫病的田间防效,筛选出了 10 个防控效果可达到 70%以上的制剂和 8 组防效在 65%以上的用药组合.该研究筛选出梨火疫病田间有效防控药剂和初花期、落花期最佳用药组合,为梨火疫病田间化学防控提供技术支撑.
Abstract
Pear fire blight is a destructive bacterial disease that has emerged in China in recent years.There is no relevant prevention and control technology experience in China,and there is an urgent need to screen effective field control agents.This study measured the field control effects of 22 agents of 12 fungicides and 10 combinations of 5 agents on pear fire blight by spraying fungicides during the initial flowering and falling flowering stages of pears.Ten agents with a prevention and control effect of over 70%and 8 combinations with a prevention and control effect of over 65%were selected.The effective field prevention and control agents for pear fire blight as well as the optimal combination of agents during the initial flowering and falling flowering stages have selected in this study,which provide technical support for the chemical prevention and control of pear fire blight in the field.
