Ivanisova E. Improvement of elements of protection technology for grape varieties, marveling anthracnose (Gloeosporium ampelophagum (Pass.) Sacc.) in Southern Ukraine.

Object - phytosanitary monitoring to detect the spread and harmfulness of anthracnose; study bioecological peculiarities of the pathogen Gloeosporium ampelophagum (Pass.) Sacc.; improvement of the system of protection from anthracnose vine plantations of Southern Ukraine. Purpose - studying of disease harmfulness on the main grape varieties in the 4 areas of viticulture Ukraine and substantiation of the system of protection from anthracnose, as an element of agricultural technology of growing grapes in Southern Ukraine.
