The Comparative Analysis of the Identification of Parasitic Fungi Races Affecting the Soil and Cultivated Vegetable and Cucurbits Crops in the Astrakhan Region
The habitat of plant pathogens does not remain constant and undergoes significant changes. Therefore, the reasons have to be revealed: the emergence of fungal infectious matter in the soil; the infection source and rate, which may have epiphytotic character under environmental factors of the disease development and consequently lead to the reduction in the yield of vegetable and cucurbits crops. As a result, it is necessary to conduct monitoring and objective diagnosis of the phytosanitary condition of the planting of vegetables and melons. In this case, the identification of parasitic fungi races of the Astrakhan region remains relevant and timely.
