Identifying Clubroot in Your Fields
Wednesday, August 21, 2019
Clubroot can be a sneaky disease – the pathogen, Plasmodiophora brassicae, causes galling of canola roots which restricts the ability of the plants to absorb water and nutrients. This can result in wilting or dying plants if the infection is severe enough.
These symptoms, however, can look very similar to canola suffering from other diseases such as blackleg, root rot or sclerotinia, insect damage such as cutworm or wireworm feeding, or environmental stresses such as drought, waterlogging or nutrient deficiencies.
From the road in particular it’s very difficult to identify clubroot infection, so it’s imperative growers get into their fields to check the crop.
