The dominant composition of phytopathogenic fungi associated with fungal infections of the sports turf

Phytosanitary monitoring of diseases on football pitch in the foothills of the North Caucasus (Sochi and Essentuki), on the football pitch and golf course in the Non-Black Earth zone (Moscow and Moscow region) in 2017-2018 was carried out to determine the prevalence of phytopathogens of sports turf in different regions of Russia. Identification of pathogens was performed using traditional phytopathological methods and molecular genetic method (PCR). In spring the football pitch in the Moscow region was dominated by fungi of the genus Fusarium sp. (including Microdochium nivale) with a prevalence of up to 56%, there were pathogens of the genera Alternaria sp. (P -22%) and Cladosporium sp. (P-8-10%), Bipolaris sp. (P-14%). In Sochi in the spring dominated by fungi genera Rhizoctonia (P=58%), Fusarium (P=45%), Cladosporium (P=42%). The golf course in spring was dominated by phytopathogenic fungi of the genus Typhula (P=55%), and fungi of the genus Fusarium were the second in prevalence, which ranged from 30 to 41%. In summer fungi of the genus Rhizoctonia sp. and Alternaria sp. significantly prevailed in the pathogenic complex of grass on the football pitch of the southern region and on the Moscow football pitch - only Alternaria sp. which is more damaged by tillering nodes and leaves. At the same time, the damage to the root system of plants by Fusarium fungi remained significant. According to the results of PCR analysis it was found that among the pathogens of root rot of plants, both in the southern zone and in the Moscow region there is F. avenaceum. According to the cultural and morphological characteristics of the plants of the football pitch in Moscow has been identified F. culmorum. The composition of pathogens in spring and summer differed slightly, depending on the location and growing conditions of the turf, but Alternaria and Fusarium spp. were constantly present in the infected area. The results of monitoring can be used to develop practical recommendations for the protection of sports turf from diseases.
