    Effect of weather conditions on PVY infections

    PRZYBYS M.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Department of Plant Breeding and Biotechnology, Pulawy, Poland
    Potato virus Y (PVY) is one of the main tobacco pathogens in the world. The main aim of this study was to determine the effect of weather conditions (temperature, humidity, precipitation, insolation) on infection of tobacco plants with PVY. To...
