Fusarium posing major problem for Manitoba crops

MarketsFarm — Most of the growing areas in Manitoba are at a high to extreme risk for fusarium head blight, according to the latest weekly crop report from Manitoba Agriculture. The report, dated Tuesday, noted the province’s western and central regions are most at risk, along with some parts of the eastern region. The eastern

Alberta opts for education over regulation of fusarium head blight

The move better reflects the reality facing farmers on the ground

The Alberta government will stop trying to regulate fusarium head blight (FHB) in favour of managing the fungal disease that can reduce yield and quality in infected wheat and barley. Alberta Agriculture Minister Devin Dreeshen announced June 3 that Fusarium graminearum (Fg) is being removed from the province’s Pest Nuisance Control Regulation of the Agricultural Pests Act — a move


Alberta deregulates fusarium

Crop disease comes off province's 'zero tolerance' list

Alberta is moving to keep fusarium in check by means other than the “zero tolerance” policy it has in effect on agricultural pests such as rats, rabies and clubroot. Agriculture Minister Devin Dreeshen announced a ministerial order Wednesday to remove Fusarium graminearum from the list of pests covered by the Pest and Nuisance Control Regulation,

VIDEO: Timing fungicide decisions in canola and cereal crops

Crop Diagnostic School: A relatively dry growing season in 2019 didn't rule out fusarium issues

At Crop Diagnostic School in July, David Kaminski, plant pathologist with Manitoba Agriculture, said 2019 was a challenge for producers when it came to timing fungicide applications. In this video, Kaminski discusses some of the conditions Manitoba producers faced this growing season in their canola and cereal crops and some of the factors at play

Grain grading revamp may add falling number, DON as factors

Two significant grain specs that aren’t yet factors for a crop’s official grade are now under consideration to join that official list. The Canadian Grain Commission on Monday put out a call for “grain sector stakeholders” to submit their views before May 10 on a proposal for falling number and deoxynivalenol (DON) to both become


Conditions ripe for fusarium, vomitoxin in wheat

Our History: September 1985

The front page of the Sept. 5, 1985 issue reported that trace amounts of fusarium and vomitoxin were being found in Manitoba wheat after a wet, cool growing season. Wet weather was to continue and harvesting was delayed, with particular damage reported to that year’s potato crop. On Sept. 19 we reported that there had

Pearce: Multiple modes of action an emerging reality for fungicides

As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species

July 16th FHB Risk Map

Fusarium head blight risk maps for 2018

[UPDATED: JULY 16, 2018] Fusarium head blight (FHB) risk maps are posted daily courtesy of Manitoba Agriculture. During the winter wheat flowering period up to the end of the flowering period for spring wheat, these risk maps will be provided for you here. Warm, humid conditions occurring when the crop is susceptible to infection (during flowering) are favourable to


Crops are stagey this year, making finding the right window for fusarium head blight fungicide applications an even 
tougher target.

Heads-up for fusarium head blight

With so many things in farming timing is everything

Early flowering is the time to apply a fungicide to suppress fusarium head blight in winter and spring wheat. But there are things to consider, including if weather conditions are right for the disease (moist and warm), and if the crop is worth investing in, says Manitoba Agriculture’s field crop pathologist Holly Derksen.

On watch for sick seedlings?

Sparse emergence might be more than a germination issue, Manitoba Agriculture warns

Poor emergence is a common story for crops caught by lack of rain this year, but seedling disease may be another culprit. Manitoba Agriculture field crop pathologist Holly Derksen says seedling disease may mimic a poor stand, particularly if infection came in on the seed or if the germinated seed is exposed before it breaks
