Abstract
- Sclerotinia stem rot in canola was widespread in most of the canola growing regions of Western Australia in 2013. Production losses from Sclerotinia are estimated at over $59M in WA last year.
- Late applications of Prosaro @ 450ml/ha at or after 50% bloom were most effective in controlling the disease and improving the yield in canola in 2013.
- Variety maturity (flowering time) had no effect on Sclerotinia incidence in 2013.
- Trial data suggest that it may be possible to predict the outbreak of disease. This could aid in decision making with regards to timings of spray application of fungicide in 2014.
