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

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. Last week

Take-all infection causing shiny black discolouration of lower stem area of wheat plant and poor root development. Note black colour and almost absence of feeder roots.

How wheat can root out the take-all fungus

A team of young researchers has now pinpointed a way of easing cereals’ risks from a deadly root pathogen

British researchers say the key to preventing the buildup of the take-all fungus is to foster beneficial fungus, which can help the plants to help themselves. Working out the right conditions to support those beneficial fungi and identifying the cereal varieties that are best suited to make the most of that help is the challenge

Wheat stripe rust, seen here, and oat crown rust, are the subjects of a joint U.S.-Australia study.

Winning the race against rust

The latest technology has scientists poised for a breakthrough 
on this tough crop disease

With its ever-evolving virulence, rust is a disease of major global concern for farmers. Now a group of scientists says cutting-edge genome sequencing technology could provide a better path forward than the traditional approaches using fungicides. The scientists, from U.S. and Australian government agencies and universities, recently released the results in mBio, a journal from


High-tech tracker to battle ancient wheat plague

Wheat rust early detection is critical and a surprising source is providing new hope

The tracking technology used to halt the deadly Ebola and Zika viruses could now be turned against wheat rust as scientists try new ways to stop the fungus devastating world grain crops. Wheat rusts are nothing new — ancient Romans honoured the rust god Robigus, hoping to protect their fields — but they are adapting

The map above shows the current risk for fusarium head blight development based on the previous seven days of temperature and

This single head, infected with wheat blast, is the first known occurrence of the disease in North America.

Wheat lost blast resistance recently

There’s good news and bad news for the world’s wheat crops. An international consortium of researchers have identified a gene in wheat that protects the plants from the deadly fungus which causes wheat blast infections. Unfortunately it would appear many strains of wheat lost this gene sometime in the 1980s, when it was inadvertently bred


Early flowering is the best time to spray wheat with a fungicide to protect it from fusarium head blight but first assess how much risk of the crop being infected.

Heads up on fusarium head blight

Early flowering is the time to apply a prophylactic fungicide on wheat but first assess the field’s disease risk

It’s time to turn a weather eye on cereal crops for fusarium infections. Fusarium head blight damaged a lot of Manitoba spring wheat last year and farmers should be assessing this year’s risk from the fungal disease that can cut wheat quality and yield. Since wheat is most susceptible to fusarium infection at flowering, early

Alfalfa weevils at high levels, more stripe rust detected

Manitoba Insect & Disease Update for June 21

Alfalfa weevil has been reported at high levels in fields in the Interlake, Southwest, and Northwest. There are some lingering cutworm issues in the northwest, although populations of cutworm in many locations are turning to pupae. Stripe rust has been detected in more locations around Manitoba. The disease is known to have overwintered in Manitoba near Austin. Reports have come in of detections
