SEED INFECTION OF MAIZE WITH FUSARIUM AND PENICILLIUM AND IMPACT OF HYDROTHERMAL CONDITIONS

Abstract

The paper presents the results of the analysis of seed infection of different maize hybrids in Belarus for 2013–2016. As a result of the research a high infection of seeds with phytopathogenes (up to 86,6 %) with Fusarium domination (11,3–53,4 %) was determined. The share of Penicillium spp. amounted to 0,6–15,4 %. The hybrids Dneprovsky 181 SV, Polessky 185, 202, 212, 214, 218 SV, Mos 182 SV, Kubansky 140 SV and Poltava demonstrated the lowest infection of seeds with Fusarium – 11,3 %–53,4 %. The impact of mid July-September weather conditions on infection of seeds with Fusarium spp. and Penicillium spp. was identified: the higher precipitation provision is, the higher seed infection is.
