Field efficacy trials of 22 fungicides against pear fire blight

doi:10.16178/j.issn.0528-9017.20230724

Abstract

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.

Key words: pear fire blight, field experiment, prevention and control effect
