Reading Time: 2 minutes 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

Root rot disease could become the clubroot of pulse crops
For pulse growers, aphanomyces has all too much in common with canola’s clubroot
Reading Time: 3 minutes Nervous eyes are watching it, and voices are already whispering that it may become the clubroot of pulse crops.

Your soil needs crop diversity
Stacked rotations may be worth more research, but until then, diversity is your best profit management tool
Reading Time: 4 minutes Healthy soil is the craziest, busiest jungle you can imagine. One gram of clubroot-infested soil can have a billion clubroot spores. A billion! All in a pinch of soil the size of a Skittle! Fusariums, pythiums, rhizoctonia and countless other beneficial fungi, bacteria and microbes are there, too. So are ions and molecules of calcium, […] Read more

Often, however, it’s even worse in canola, as becomes clear with a quick look at clubroot and blackleg. Both attack canola and while scientists and farmers are doing their best to […] Read more
Against clubroot, ‘I’-rated canola sits between ‘R’ and ‘S’

The Alberta Canola Producers Commission (ACPC) warned Monday that growers will need more specifics about claims that a new canola variety has […] Read more
Manitoba canola pest lab backed for equipment, research
Reading Time: 2 minutes A new Manitoba lab with federal, provincial and canola industry backing has been opened with the goal of staying a step ahead of canola diseases such as clubroot and verticillium wilt. The federal and Manitoba governments on Thursday announced $969,000 for equipment, including a polymerase chain reaction (qPCR) machine, and $250,000 for research at the […] Read more
2015 crop disease outlook
The 2014 growing season saw some serious disease outbreaks, and it looks like 2015 will too
Reading Time: 7 minutes Crops diseases are always a risk for grain growers. Be it rust in the 1950s, fusarium in the 1990s or clubroot today, it seems there’s always a new pestilence lurking just around the corner. Country Guide spoke to crop disease specialists from the three Prairie provinces late this fall about what they saw in the […] Read more
The do’s and don’ts of clubroot
Specific, timely actions can help prevent the spread of disease in your soil
Reading Time: 2 minutes By now it’s clear. Some control strategies work. Others, says Dan Orchard, just don’t. Pulling plants from dead patches at the end of the season and looking for the disease certainly worked. But it would have worked even better if the recommendation right from the start had been to pull plants and check the roots. […] Read more
