Virulence of Biopesticide and Fungicide Complexes on the Pathogen of Peach Shoot Blight
摘要
Abstract
Objective] To screen the effective biopesticides and their mixtures with fungicides against the pathogen Phomopsis amygdali of peach shoot blight.[ Method] The virulence of 10 biopesticides against P.amygdali was tested in the laboratory by mycelial growth inhibition method, and then the mixtures of biopesticides with high virulence and prochloraz, carbendazim and diniconazole respectively, were detected for their laboratory toxicities.[Result] Zhongshengmycin had the strongest virulence, with EC50 value of 0.041 9 μg/mL, and shenqinmycin and tetramycin had better antimicrobial effects, with EC50 values of 0.231 4 and 0.655 4 μg/mL, respectively.When shenqinmycin was mixed with the three fungicides in different proportion, the synergistic ratio (SR) values were all greater than 1.5, having increased toxicity effect.When mixed with the three fungicides, zhongshengmycin and tetramycin had mixed ratios for additive and synergistic toxicity effects. [ Conclusion] The study indicates that the biopesticides mixed with chemical fungicides can increase the toxicity to P.amygdali.关键词
