摘要
[目的]研究7种不同杀菌剂对葡萄灰霉病的室内抑菌活性。[方法]试验利用PDA培养基,分别加入不同药剂,并将7种药剂设置不同处理浓度,每个处理3次重复,经培养箱培养后测定抑菌率,计算EC50值(半致死浓度)。[结果]50%速克灵WP、60%腈菌唑EC和40%嘧霉胺WP对葡萄灰霉病具有较强的抑菌作用,其中速克灵最强。[结论]该研究筛选出有较好防治效果的杀菌剂,为葡萄灰霉病的防治提供参考。
[Objective] The aim was to study the antibacterial activity of 7 different fungicides on grape Botrytis cinerea Pers.[Method] The PDA medium with different medicament were set 7 treatments.Each treatment had 3 repeats and cultured in incubator.The antibacterial rate and EC50 value were determined.[Result] 50%WP,60%EC and 40%WP had bacteriostatic action and 50%WP was the best.[Conclusion] The better control effect of fungicide was selected.These would provide reference to Botrytis cinerea control.
