为了研究芸苔素内酯与苯甲·丙环唑共同作用防控玉米小斑病的效果,上海交通大学农业与生物学院、上海绿泽生物科技有限责任公司研究人员利用生长速率法和孢子萌发法以及人工接种方法,测定了芸苔素内酯对玉米小斑病菌的抑制作用,同时调查其防效并测定了防御反应各项指标。结果显示,芸苔素内酯对玉米小斑 In order to study the synergistic effect of brassinolide and trimethoprim-pyrazole on the control of corn leaf spot, researchers at Shanghai Jiao Tong University School of Agriculture and Biology, Shanghai GreenTech Biotechnology Co., Ltd., using growth rate method and spore germination Method and artificial inoculation method were used to determine the inhibitory effect of Brassinolide on S. hyopneumoniae and to investigate its control effect and to determine various indicators of defense response. The results showed that brassinolide had little spots on corn
