枯草芽孢杆菌M6和木霉10对番茄灰病的防治效果研究

分别研究了枯草芽孢杆菌M6、木霉10和两者配成的复合菌剂W对番茄灰霉病的防治效果,测定了它们对番茄灰霉病的抑制作用.结果表明,枯草芽孢杆菌M6、木霉10、复合菌剂W对番茄灰霉病均有抑制作用,但复合菌 剂W对番茄灰霉病抑制作用更强,抑制率达到62.2％,且复合菌剂W的使用浓度不能低于105 cfu/mL.田间防治试...

Biological Control Efficiency of Bacillus subtilis M6 and Trichoderma 10 to Botrytis cinerea

In this paper,we studied the control efficiency of Bacillus subtilis M6,Trichoderma 10 and their compound microbial agent W to Botrytis cinerea respectively,and we also measured their inhibitory effects against Botrytis cinerea.The results showed that Bacillus subtilis M6,Trichoderma 10 and the compound microbial agent W could all inhibit the growth of Botrytis cinerea,but the effect of compound microbial agent W was best,with the inhibition ratio of 62.2%,in addition,the results of the laboratory test showed that its concentration should be higher than 105 cfu/mL.The results of the field test showed that the compound microbial agent W could effectively control tomato gray mould,and as the concentration increased,its control efficiency became better.After twice continuous spaying of the agent,the control efficiency of the 800-fold diluted solution of the compound microbial agent W was over 80%,which apparently surpassed the 800-fold diluted solution of 75% Chlorothalonil wetable powders.The control efficiency of the 800-fold diluted solution of 75% Chlorothalonil wetable powders was the same with the 1 000-fold diluted solution of the compound microbial agent W.And both the 800-fold and 1 000-fold diluted solutions of the compound microbial agent W could substitute for the chemicals to reduce the chemicals residues and environment pollution.
