芽孢杆菌与化学杀菌剂复配防治葡萄灰霉病的研究
Research on Combination of Bacillus and Fungicide to Control Gray Mold of Grapevine
摘要
Abstract
In order to reduce the use of chemical pesticides to control gray mold of grapevine and improve the effect of biocontrol Bacillus on Botrytis cinerea,in this study,effective chemical agents and biocontrol Bacillus for gray mold of grapevine were screened by plate confrontations and growth rate methods,and the two were combined,and the control effect of the combined agents on gray mold of grapevine was confirmed through indoor inoculation and pot experiment.The results showed that the chemical iprodione and Bacillus velezensis GSBZ09 had the best inhibition effect on Botrytis cinerea,and the EC50 value of iprodione was the lowest(6.46 mg·L-1).The antagonistic effect of Bacillus velezensis GSBZ09 was the strongest,and iprodione had no effect on the growth of Bacillus velezensis GSBZ09.When the combined volume ratio of iprodione and Bacillus velezensis GSBZ09 was 3∶1,the control effect of indoor and pot experiment was as high as 92.93% and 80.63%,respectively,which was superior to the control effect of isomylurea single and Bacillus velezensis GSBZ09 single.关键词
