几种杀菌剂对葡萄灰霉病的抑制效果研究

Inhibiting Effect of Several Fungicide on Botrytis cinerea Pers.

研究了依天得、依天得Ⅰ号、依天得Ⅱ号、依天得Ⅲ号、多抗霉素B、多菌灵50%可湿性粉剂对葡萄灰霉菌的抑制效果。结果表明：多抗霉素B 800~2 000倍液、依天得和依天得Ⅲ1 000~2 000倍液、依天得Ⅰ号1 000倍液、依天得Ⅱ号500倍液、50%多菌灵800倍液均能完全抑制灰霉菌的生长;依天得、依天得Ⅰ号和依天得Ⅲ号,随着溶液浓度的降低,对灰霉病的抑制作用逐渐降低;多菌灵和依天得Ⅱ号,随着溶液浓度的降低,对灰霉病的抑制作用无明显变化。

The inhibition effect of Brevibacterium,Brevibacterium Ⅰ,Brevibacterium Ⅱ,Brevibacterium Ⅲ,Polyoxin B,carbendazim 50% wp on Botrytis cinerea Pers.was studied.The results showed that 800 to 2 000 time solution of Polyoxin B,1 000 to 2 000 time solution of Brevibacterium and Brevibacterium Ⅲ,1 000 times solution of Brevibacterium Ⅰ,500 times solution of Brevibacterium Ⅱ and 800 times solution of carbendazim 50%wp all can inhibite the growth of Botrytis cinerea.As the liquid concentration decreased the inhibition of Brevibacterium,Brevibacterium Ⅰ,Brevibacterium Ⅲ on Botrytis cinerea Pers.were reduced.As the liquid concentration decreased,the inhibition of carbendazim 50% wp and Brevibacterium Ⅱ on Botrytis cinerea Pers.had no significant change.
