Thus, extended application on the biocontrol against strawberry anthracnose is proposed. In this project, the effective concentration and applicatiom method of Paenibacillus for the efficacy will be investigated to establish the biocontrol target for the bioagent made with Paenibacillus. Also, the suppression effect of Paenibacillus on strawberry anthracnose via host response will be examined. Secondly, the bioactive compounds produced by Paenibacillus for the antagonistic activity will be purified and analyzed biochemically. The growth and survival periods of Paenibacillus on strawberry plant surface will be examined. Then, the fermentation and toxicity test will be performed. All these tests will provide basic informations for the for the biocontrol of strawberry fungal diseases and the development of this bioagent constituent.類芽孢桿菌生物防治草莓炭疽病PaenibacillusBiocontrolStrawberry anthracnoseAntifungal compounds
