High soil moisture is a high risk of clubroot in rapeseed; Southern Poland is at risk

High soil humidity and flooding of winter rapeseed plantations, which often occurred in southern Poland in mid-September this year due to the Genoese lowlands, are ideal conditions for the development of clubroot. Soils in southern regions of Poland are infected with this pathogen and water could have contributed to the fact that a greater number of plantations and plants would be infected. - Wherever water flows through agricultural land, the presence of spores of the clubroot causative agent causes the spread of this disease to adjacent fields - informs IOR-PIB in Poznań in phytosanitary communications. Spores flow with water As scientists from IOR-PIB in Poznań add: - The flood situation caused water to emerge from its natural channels and spread with spores over very large surfaces, creating an additional risk of a wider spread of the pathogen - Plasmodiophora brassicae, which causes clubroot. This is important because in these regions and provinces the flood caused a lot of ...
