鲍曼菌素对梨黑斑病菌的毒力及药效评价
Evaluation of virulence and efficacy of Acinetobacter baumannii against Alternaria alternata
摘要
Abstract
[Objective]The present study was conducted to explore the antifungal effects of Acinetobacter baumannii and its mixtures against Altemaria altemata. [ Method ] Agar plate tests were conducted to test the inhibitory effects of A. Baumannii and its mixtures on mycelial growth of A. Altemata. And field investigation methods were used to determine its controlling effects. [Result]A. Baumannii showed strong antifungal activity to mycelial growth of A. Altemata and its activity increased significantly with increasing its concentration. The toxicity measurement indicated that mixtures of A. Baumannii and pyrimethanil in 4-7∶6-3 ratio showed significant synergistic effects, and the highest SR of A. Baumannii: pyrimethanil was 2.58 with ratio of 5∶5. Field investigation results showed that the control efficacy of 333-500 mg·L-1 40% mixture of A. Baumannii and pyrimethanil was significantly higher than signal dose of A. Baumannii, pyrimethanil and carbendazim. [Conclusion]A. Baumannii and its mixtures with different fungicides had strong antifungal activity, and it may be recommend as a new biological fungicide for controlling plant diseases.关键词
