Blackleg (Leptosphaeria maculans) Severity and Yield Loss in Canola in Alberta, Canada
Blackleg, caused by Leptosphaeria maculans, is an important disease of oilseed rape (Brassica napus L.) in Canada and throughout the world. Severe epidemics of blackleg can result in significant yield losses. Understanding disease-yield relationships is a prerequisite for measuring the agronomic efficacy and economic benefits of control methods. Field experiments were conducted in 2013, 2014, a...
متن کاملBest Management Practices for Blackleg Disease of Canola
Blackleg disease of canola in western Canada has been effectively managed for the past 20 years through a combination of resistant varieties, adequate crop rotation intervals and good agronomics. Increased canola production in western Canada, in large measure through more frequent cropping in the rotation, has increased the risk that resistance to blackleg in current varieties may be defeated. ...
متن کاملDetection of Leptosphaeria maculans and Leptosphaeria biglobosa Causing Blackleg Disease in Canola from Canadian Canola Seed Lots and Dockage.
Blackleg, caused by Leptosphaeria maculans, is a major threat to canola production in Canada. With the exception of China, L. maculans is present in areas around the world where cruciferous crops are grown. The pathogen can cause trade barriers in international canola seed export due to its potential risk as a seed contaminant. The most recent example is China restricting canola seeds imported ...
متن کاملEpidemiology / Épidémiologie Effects of crop rotation and tillage on blackleg disease of canola
The effects of a 4-year crop rotation and two tillage systems on blackleg (Leptosphaeria maculans) disease of canola were determined in a field experiment carried out from 1999 through 2002 at Carman, Manitoba. Crops in rotation were canola (Brassica napus) (C), wheat (Triticum aestivum) (W), and flax (Linum usitatissimum) (F). Rotations were done under conventional tillage (T) or zero-till (Z)...
متن کاملPterostilbene Is a Potential Candidate for Control of Blackleg in Canola
Two stilbenes, resveratrol and pterostilbene, exhibit antifungal activity against Leptosphaeria maculans, the fungal pathogen responsible for blackleg (stem canker) in canola (Brassica napus). In vitro studies on the effect of these stilbenes on L. maculans mycelial growth and conidia germination showed that pterostilbene is a potent fungicide and sporicide, but resveratrol only exerted minor i...
