Abstract:
Cryptogamic diseases are one of the biggest problems in viticulture. Chemical treatments used for controlling them are harmful to ecosystems and humans, so it is imperative to find sustainable alternatives. We hypothesize that in the autochthonal microbiome from vineyards exist microorganisms with biocontrol potential against these diseases. 60 Chaetomium and Chaetomium-like strains have been isolated and identified from soil samples. C. globosum, C. cochliodes and A. cupreus have been tested in vitro against Diplodia seriata and Didymella glomerata. C. globosum and C. cochliodes are especially detachable against D. glomerata with 62,67% of inhibition of the mycelial growth.
