Studies have been conducted in Canada and the United Kingdom on the efficacy of fungicides on blackleg; however, none of them appear to evaluate the economic benefit or loss of applying fungicides. found that the fungicide flutriafol coated on fertilizer had a very limited effect on blackleg infection early in the season. Kharbanda reported that the fungicide prochloraz reduced blackleg severity in greenhouse studies, but failed to reduce blackleg severity in field studies. Triazole fungicides have been found to be effective in controlling blackleg.
Objectives:
1. Establish a blackleg field nursery to evaluate commercial cultivars, breeding lines and germplasm for resistance to blackleg.
2. Evaluate currently registered, non-registered and experimental fungicides for their efficacy on control of blackleg
3. Determine the economic benefit/loss of applying Quadris (azoxystrobin) to canola cultivars with susceptible, moderately-resistant and resistant blackleg ratings.
