Weeds as Reservoirs of Viruses in Agrobiocenoses of Legumes in Ukraine

Abstract

This paper is the review of literature data on the prevalence of weeds as possible reservoirs of plant viruses in agroecosystems of Ukraine. The information presented here about the most distributed weeds as reservoirs of harmful plant viruses will be useful for understanding the pathogens ecology, analyzing the virus epidemiology and for disease management. Since legumes are the main crops grown in Ukraine, the paper focuses on weeds spreading in the agrosystems of cultivated plant. The paper provides information about the primary sources of soybean viruses (Soybean mosaic virus, Cucumber mosaic virus, Alfalfa mosaic virus, Tomato ringspot virus) and bean viruses (Bean yellow mosaic virus, Bean common mosaic virus) as well as the main factors contributing the virus transmission in agrocenosis.
