Abstract: The aim of this study was conducted to provide reference for the screening of novel fungicides and their scientific application in fields. 2010-2012, 6 experimental fungicides and 3 bio-control agents were selected to conduct field efficacy trials used to control Chinese chives gray mold in fields in 3 consecutive years. The results showed that, the control effect of carbendazim 50% WP, procymidone 50% WP, pyrimethanil 40% SC, chlorothalonil 75% WP, difenoconazole 10% WDG, SYP-Z048 25% EC, polyoxin 10% WP, berberine 0.5% and pythium oligadrum 106 spores/g WP were respectively 69.09% , 63.36%-67.62% , 64.90%-76.41% , 72.62% , 54.32%-72.61% , 82.14%-84.72% , 22.04% , 38.07%和12.15% . Carbendazim 50% WP, procymidone 50% WP, pyrimethanil 40% SC, chlorothalonil 75% WP and difenoconazole 10% WDG exhibited common efficacy in Chinese chives gray mold management, while SYP-Z048 25% EC had a safety and steady efficacy with a control effect of more than 80%. 3 bio-control agents also performed certain effect.
