The present invention relates to antifungal biocontrol agents which enhance plant growth and reduce plant diseases by suppressing fungal pathogens, and the manufacturing and application methods thereof. The antifungal biocontrol agents of the present invention consist of one of the newly isolated strains of Streptomyces sp. WYE 20 (KCTC 0341BP) and WYE 324 (KCTC 0342BP) and a delivery medium which carries and stabilizes the cells. In particular, WYE 20 and WYE 324 of the present invention exhibit strong antifungal activity against Rhizoctonia solani and Phytophthora capsici and can be used in various ways to reduce fungal diseases in plants such as cucumber (Cucumis sativus L.), pepper (Capsicum annuum L.), and golf course turfgrasses.
La présente invention concerne des agents de lutte biologique antifongique qui améliorent la croissance des végétaux et diminuent les maladies végétales en luttant contre les pathogènes fongiques. L'invention concerne également des procédés d'élaboration et d'application de ces agents. Les agents de lutte biologique antifongique de l'invention sont constitués, d'une part de l'une des souches récemment isolées WYE 20 (KCTC 0341BP) et WYE 324 (KCTC 0342BP) de l'espèce Streptomyces, et d'autre part d'un milieu véhicule servant à transporter et stabiliser les cellules. En l'occurrence, faisant preuve d'une puissante activité antifongique dirigée contre Rhizoctonia solani et Phytophthora capsici, les souches WYE 20 et WYE 324 de l'invention peuvent servir de différentes façons à lutter contre les maladies fongiques de végétaux tels que le concombre (Cucumis sativus L.), le piment rouge long (Capsicum annuum L.) et les herbes à gazon des terrains de golf.
