Phytoncides in the fight against bacterial and viral diseases of plants

Montina Irina Mikhailovna

The article presents an overview of the main phytoncidal plants and their effects on bacterial and viral diseases of plants. The mechanism of action of plant phytoncides on various microorganisms is described. It is shown that phytoncides differ from other chemicals in that they do not allow microorganisms to create any of their own defense mechanisms. It is noted that the bactericidal effect of most phytoncidal plants on pathogenic microorganisms depends on the season of the year. Most hardwoods are characterized by an active phytoncidal effect in the summer, however, for some species, several periods of such activity are characteristic. The positive effect of phytoncides on the fruits of plants, especially during storage, has been shown. The inhibitory effect of phytoncides on the development of plant viruses is described.
