Abstract

A soil born strain of Aspergillus flavus (fig 3) was isolated from a compost picked up and created in Chestnut orchard, not only as possible substratum to use as fertilizer, but also as possible substratum from which pick up fungi from his inside, to use as antagonists against several illnesses of the chestnut. Phytophthora cinnamomi is the causal agent of “ink disease” of Chestnut, one of the most dangerous parasite for this plant. It causes withering of the outer leaves and the drying out of the top shoots with a gradual death of the branches starting with the topmost ones. (fig 1) Usually a lesion occurs at the base of the trunk out of which a dark watery liquid exudates. (fig 2) The A. flavus strain (ECO-6) culture filtrates showed a strong inhibitory activity against this pathogen as well as towards P. cactorum and P. nicotianae, which are pathogen of strawberry, tomato, tobacco and many other plants
