Field Efficacy of Biocontrol Agents in Controlling Wheat Scab
摘要
Abstract
To improve the control effect of wheat scab and screen out an efficient biological control agent, the study takes'Zhengmai7698'as test material, to examine the effect of five different biocontrol agents, which were Bacillus Subtilis WP, Amino-oligosaccharide AS, Shinyomycin SC, Oligosaccharin AS and Jinggang Bacillus Cereus SC and two different Carbendazims, which were Jinggang Carbendazim SC and Carbendazim WP, on wheat scab in field in Henan Plain. The results indicated that in heavy wheat scab periods, twice usages of biocontrol agents significantly improved the prevention effects of disease spike and disease index, twice usages should be conducted in heavy disease years. Furthermore, among the biocontrol agents applied in the initial stage of flowering and the stage of blossoming, the best treatment of wheat scab was Jinggang Carbendazim, with the disease spike prevention effect of 78.21% , and disease index prevention effect of 80.55% , followed by Carbendazim, Shinzamycin and Bacillus Subtilis , whose control efficiency was all above 75% and had no significant difference. Jinggang Carbendazim had the best yield-increasing effect with a rate of 26.51% , then was Carbendazim with the yield-increasing rate of 25.03% . To conclude, Jinggang Carbendazim is the first choice in eastern Henan plain, while Carbendazim remains useful. Bacillus Subtilis and Shinzamycin could be used as feasible alternatives of Carbendazim.关键词
