Clubroot in brassicas, and viruses carried to lettuce by the olpidium fungus, are highly destructive diseases that can infect plants during propagation. There are potential alternatives to current control strategies but they need to be rigorously tested before being trialled commercially. The project New chemical and nonchemical means of killing clubroot and olpidium resting spores were tested and their effectiveness compared against a standard treatment. Results Microwaves, pulsed light and ozone appear either to have no potential or are not commercially viable for killing the resting spores of these two fungi at present. Heating at 65ºC for five minutes controlled olpidium resting spores. They were also controlled by treating with steam for two and a half minutes but higher temperatures were needed for clubroot spores. At the concentrations of disinfectants initially tested, Jet 5 was more effective than Jet 5 or Difficil-S, following treatment for five minutes
