极细链格孢激活蛋白与氨基寡糖素复配制剂防控白菜软腐病的协同增效作用
Synergistic Effect of Plant Activator Protein and Amino-Oligosaccharin on Chinese Cabbage Soft Rot
摘要
Abstract
Laboratory toxicity tests and field efficacy trials were conducted to screen green prevention and control technologies for Chinese cabbage soft rot,using a mixture of plant activator protein and amino-oligosaccharin.In the combined toxicity screening tests,an in-vivo inoculation method was used to determine the effects of the plant activator protein and amino-oligosaccharin individually,as well as their mixture in different proportions,against Chinese cabbage soft rot.The results showed that all the five tested combinations exhibited good synergistic effect,with the 1∶1 ratio of plant activator protein to amino-oligosaccharide achieving the best control effect.Field efficacy trials were conducted using 6%oligosaccharides·chain protein(1∶1)wettable powders(WP)in Xinji Town and Dawu Town of Shandong Province,Xinzhou District of Wuhan and Moudao Town of Hubei Province.The results demonstrated that 6%oligosaccharides·chain protein(3%+3%)WP at 75～100 g/667 m2 provided a control effect exceeding 65%against Chinese cabbage soft rot and increased the yield significantly up to 12.16%.关键词
