- Аннотация: The potato golden cyst nematode, Globodera rostochiensis, was revealed in tomato and potato plantations in the Volgograd region of Russia. Potato virus Y (PVY) and Potato virus X (PVX) were also found on the territory for the first time. PCR analysis revealed potex- and potivirus infection on tomato plants. In addition, the negative effect of a single infection with X, M, and S viruses and mixed infections (X + S, X + S + M , X + S + M + L viruses) was also demonstrated in field-plot tests with potatoes. It was shown that mixed viral infections reduce the yield of potatoes in 2-3 times. As a result of our investigations, we found that Baermann funnel method is not valid for virus-vector nematodes extraction and decanting and sieving technique should be used in this case.
