Reading Time: 3 minutes Clubroot’s march through Alberta is relentless and the level of infestation here is 100 times — or even 1,000 times — worse than in Saskatchewan and Manitoba. But there is a bit of good news: Moving to a three-year rotation is more effective than previously believed, says a Canola Council of Canada agronomist. “New work […] Read more
The clubroot onslaught continues — but there is some hopeful news
Alberta fields are seeing massive numbers of clubroot spores, but new research has found a 90 per cent drop-off after a two-year break
New canola variety a milestone in the battle against clubroot
Double resistance a big step forward, but clubroot strains are quickly multiplying
Reading Time: 3 minutes A new canola variety resistant to multiple strains of clubroot will hit the market in time for spring seeding. But the new variety from Crop Production Services will only be available in limited quantities and a clubroot expert says growers can’t expect it to be “a saviour.” CPS Canada says the variety, Proven Seed PV […] Read more
Time to test all Man. fields for clubroot, province says
Distribution of clubroot spores across Manitoba now suggests it’s time for more widespread testing to keep the disease in check, the provincial ag department recommends. 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
Canola program stacks genes against new clubroot
Rather than send out a canola variety with a single source of resistance against clubroot — especially the disease’s most recent pathotype — Agrium’s CPS division has stacked several sources into the new hybrids it’s sending for testing this summer. Crop Production Services on Monday announced its “next generation” of Argentine canola hybrids shows “high […] Read more
Crop pest and disease watch for 2015
Some of the usual suspects could be back this year, especially if you are pushing your rotations
Reading Time: 6 minutes The new growing season is underway, with a combination of old and new challenges and opportunities. Alberta Farmer reporter Alexis Kienlen asked some experts about things that producers should look out for this growing season. Here’s what they had to say: Plant diseases It’s difficult for plant pathologists to predict the possibility of diseases, said Kelly […] Read more
Clubroots beating all resistant canolas across Alta.
A study of 27 canola fields across Alberta has found 16 infected with clubroot pathotypes able to cause “high levels” of the disease — in canola plants with clubroot-resistant genetics. What’s more, the clubroot pathogen isolated from “many” of the infected fields in the study was virulent on all clubroot-resistant canola cultivars, the Canola Council of Canada […] Read more
Canola growers get grim warning on clubroot threat
No varieties have strong resistance to new pathotypes, longer rotations are ‘the best management option left’
Reading Time: 2 minutes The Alberta Canola Producers Commission is urging producers to step up their efforts to contain clubroot in the province. “Since new data indicates some forms of clubroot resistance are no longer functioning well against new clubroot pathotypes in some of the heavily infested fields, we encourage you to consider a comprehensive management plan that includes all […] Read more
New canola variety offers middle-of-the-road protection against new strain of clubroot
A new canola variety from Canterra Seeds with ‘intermediate resistance’ to a new strain of clubroot will be available in limited amounts this growing season
Reading Time: 2 minutes A new canola variety has shown some promising resistance to a new strain of clubroot that was found near Edmonton in 2013 and has since spread to nearly 30 fields. But it won’t offer true resistance, says a plant pathologist from the University of Alberta. “This variety had very, very strong resistance to the pathotypes […] Read more
Against clubroot, ‘I’-rated canola sits between ‘R’ and ‘S’
A new canola variety billed with “intermediate” reaction against a new pathotype of clubroot is being placed in the zone between “resistant” and “susceptible.” Canterra Seeds, the Winnipeg firm marketing the new CS2000 hybrid variety, clarified its claim for the seed in a statement on a company blog Wednesday, granting many growers may be seeing the […] Read more
Canola variety’s clubroot claim taken with caution
A new variety of canola with “intermediate” resistance to a new type of clubroot may be cause for optimism, but Alberta’s canola grower group says farmers need to know more before they buy. The Alberta Canola Producers Commission (ACPC) warned Monday that growers will need more specifics about claims that a new canola variety has […] Read more
