Phytopathological estimation of vegetable seed plant and protection methods

Abstract

The main diseases of the testes of biennial vegetable crops are considered at the early stages of the life cycle and before leaving in the winter in direct culture. The features of the development of phytopathogenic fungi and bacteria that are active at high positive temperatures are described. Proposed ways to protect plants. The studies were conducted in 20162018 in the fields of the FGNBU of the Federal Agrarian Scientific Center of the Republic of Dagestan. For seed farms, a system of measures has been developed to prevent the occurrence of the water content of these phytopathogenic fungi. They are based on effective plant protection systems and agrotechnical techniques. Hot and humid conditions (2016) resulted in the activation of fungi of the genus Fusarium, Rhizoctonia and Phythium on the testicles, which sharply increased the infection of beets with fusarium wilt, cabbage with black leg, carrots with felt rot. In this regard, the testes protection system should be developed in advance and rely mainly on preventive measures.
