Technology of restoration of phylloxerasuppressed root-related grape plants

Relevance . The transition of viticulture to the cultivation of grape plantations in a grafted culture has only partially solved the problem of phylloxera. Taking into account the shortcomings of the instilled culture, the problem remains urgent. In view of this, we consider it necessary to preserve and expand the indigenous grape culture. The fundamental solution to the problem should be the creation and introduction of pest-resistant genotypes based on modern advances in genetics and breeding, suitable for growing in a root crop. Currently, there are quite a lot of high-quality domestic varieties tolerant to root phylloxera and suitable for cultivation in the arsenal of domestic viticulture. native culture. Economically justified and scientifically justified ways to solve the phylloxera problem may be the introduction of pest-tolerant varieties of domestic breeding and the use of technological regulations for the use of physiologically active compounds that enhance physiological immunity and resistance of grapes to phylloxera.
