Reading Time: 6 minutes In the mid-2000s, Albert Tenuta raised a few eyebrows when he referred to the discovery of soybean cyst nematode east of Toronto as good news. The field crops pathologist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) meant that once the pest was identified, it could be monitored, and growers could better […] Read more
Clubroot calls for diligence, not alarm
The surprise discovery of clubroot in Ontario will force canola growers to adapt to the disease now in order to avoid future complications
Clubroot arrives in Ontario canola
Reading Time: 2 minutes Ontario has its first case of clubroot disease in canola — and further testing has confirmed clubroot in canola fields across the province. During the 2016 growing season an agronomist in the Verner area of northern Ontario examined a canola field and found the distinctive clubbed roots, said Meghan Moran, canola and edible bean specialist […] Read more
The fine balance of controlling crop diseases
It's a classic example of where short-term decisions can mean long-term problems
Reading Time: 7 minutes Randy Kutcher recalls that when he moved to Saskatchewan 25 years ago, farmers were using hardly any fungicide. “They were using a bit of fungicide for sclerotinia in canola, and that’s about it. Now it’s pretty much part of the program, and often crops are getting two or more applications, and it’s almost become like […] Read more
Crop diseases take a bit of a break in 2015
Drier conditions this past season kept a lid on most crop diseases — but this is probably just a brief respite until environmental conditions line up again
Reading Time: 8 minutes The bad news is that dry weather cut yields across much of the Prairies in 2015. The consolation? This same weather kept fungal diseases in check. In fact, areas that were in the sweet spot of lower pressure but enough rainfall to carry yield were rewarded with exceptional crop quality. Country Guide recently spoke to […] Read more
Canola disease highlights from 2015
Dry conditions, especially early in the season, reduced disease severity in general in 2015. Noteworthy events are the rise of blackleg in Saskatchewan and clubroot in Manitoba
Reading Time: 6 minutes Blackleg is on the uptick in Saskatchewan. The disease survey went 10 years with blackleg bumping along the bottom of the graph at low levels. But then prevalence — the percentage of fields with some level of blackleg infestation — rose from the 10-year average of 25 per cent up to 54 per cent in […] Read more
Clubroot continues its march across prairie canola fields
So far nothing appears to have slowed the spread of clubroot, so some are suggesting it might be time to rethink our approach
Reading Time: 9 minutes Over the past dozen years the canola industry has poured an ocean of effort into halting the spread of clubroot around the Edmonton area. And while there have been advances such as new resistant varieties, one uncomfortable truth remains — the disease continues to spread. Dan Orchard, a Canola Council of Canada agronomist who discovered […] Read more
A costly approach to dealing with crop insects and weeds
A head-in-the-sand approach to unfamiliar insects, diseases and weeds simply won't do. Be observant. Early identification and fast action — when required — are best
Reading Time: 5 minutes If Dan Orchard had not discovered clubroot in an Alberta canola field in 2003, we’d all be in ignorant bliss right now. Orchard really should have recognized the scientific principle that if something isn’t “discovered,” then it doesn’t exist and we don’t have to worry about it. He should have left well enough alone, as […] Read more
Livestock biosecurity strategies come to canola
Canola and soybean farmers are just beginning to see the wave of biosecurity that could sweep them the way it swept Canada’s hog and poultry sectors
Reading Time: 6 minutes When Manitoba agronomist Terry Buss goes out on a call from the Beausejour office, he takes a big trunk full of plastic boot covers in the back of the pickup. There are disinfectants in the trunk too, and other cleaning supplies as well, and he uses them all. Buss has adopted a brand new form […] Read more
Time to test all Man. fields for clubroot, province says
Reading Time: 3 minutes 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
Reading Time: 2 minutes 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
