Clubroot is scary enough but this Canola Council of Canada video on the life cycle of the disease ups the fear factor. Above, a still from the video (available at www.clubroot.ca) shows a zoospore, an amoeba-like creature released from a clubroot spore when it senses a host plant is nearby. The zoospore, powered by two whip-like flagella, can swim a short distance in water film in the soil towards a root hair.

Since the disease appeared in Manitoba in 2009, fewer than five per cent of the province’s farms have so far been tested for the spores that cause the yield-robbing disease […] Read more
