The current occurrences of oilseed rape diseases on selected locations in the Czech Republic and the treatment indication

Popis výsledku v původním jazyce

In Šumperk and Opava region the harmfulness of diseases in oilseed rape and signaling of fungicidal treatment have been monitored in the long term. It was confirmed the strong influence of the year (temperature, relative humidity) and crop rotation on the incidence of phoma stem cancer, white rot and others. The signaling of fungicidal treatment against important pathogens of winter oilseed rape as L. maculans, L. biglobosa and S. sclerotiorum was carried out based on the evaluation of ascospores and the course of weather conditions. The number of L. maculans, L. biglobosa ascospores in the air samples was determined by microscopic analysis of captured ascospores by spore trap. The percentage of petals contamination by S. sclerotiorum ascospores was determined by culturing them on a solid medium. The ample rainfall and consequently higher temperatures in the autumn and winter had a positive impact on the development of pathogens Leptosphaeria maculans, L. biglobosa. Numerous rainfall, cool and dry weather during the flowering period negatively affected the development of the pathogen Sclerotinia sclerotiorum. The obtained results were co-funded by Ministry of Agriculture, NAZV grants QH81127 and QJ1310227.
