Digital supercluster backs precision fungicide development

Project aims at wheat leaf rust, reducing pesticide load

By ,
A West Coast ag tech company in the crop pest control business is setting its sights on wheat leaf rust, with support from one of Canada’s five research superclusters — but not the cluster you might expect. Out of the five federally-supported superclusters launched in early 2018, Protein Industries Canada has been most closely linked

New tool on the way for canola growers safeguards against blackleg

Saltro is a new seed treatment to control blackleg at the seedling stage expected to be available for the 2021 growing season

By
A new fungicide to protect canola seedlings from blackleg, a major yield-robbing disease, could be available as a seed treatment for the 2021 growing season. It’s called Saltro and was developed by Syngenta. “Syngenta anticipates registration in time to make it available for use in the 2021 growing season,” Sarah Osborne, company marketing operations manager,

A crop-by-crop rundown on sclerotinia control

Variety and fungicide are key for control, but for sunflowers there’s only one option — rotation

By
The good news is the hot, dry summer made sclerotinia somewhat scarce in canola fields this summer, but there was a minor downside — there weren’t many examples to show farmers attending a sclerotinia control session at this year’s Crops-A-Palooza, even in the inoculated demonstration plots at the Canada-Manitoba Crop Diversification Centre (CMCDC) here. But

To spray or not to spray for fungal disease

You don’t have to just pencil it in and spray anyway — there are tools to help make the decision

By
To spray or not to spray for fungal diseases? Will the extra yield offset the cost? In practice this decision is often made based on farmers’ comfort levels, but economics should always be considered, said Holly Derksen, field crop pathologist for Manitoba Agriculture, at this year’s Crop Diagnostic School in Carman. “You have to understand

UPL to buy crop chem firm Arysta

By ,
Indian chemical manufacturer UPL has raised the financial backing for an all-cash deal to become what’s expected to be the world’s fifth biggest crop chemical firm. UPL on July 20 announced it will pay $4.2 billion to buy 100 per cent of Arysta LifeScience — the maker of Everest and Inferno herbicides, among other products

Taking the guesswork out of spraying

A test kit can take a reading of disease levels in the field

Lab technicians at Quantum Genetix are working around the clock testing crop tissue samples to help farms make informed decisions in their fungicide program. “It’s a busy time of the year for us. We up our staff and we run 24 hours to make sure our machines are working,” Heather Deobald of Quantum Genetix said
Crops are stagey this year, making finding the right window for fusarium head blight fungicide applications an even

Heads-up for fusarium head blight

With so many things in farming timing is everything

By
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

By
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

Fungicide issues worse in U.S.

Boscalid and other early blight fungicides are facing down resistance in the U.S., but the issue hasn’t quite reached fever pitch in Manitoba

By
It’s not time to panic on boscalid resistance, at least not north of the border. The U.S. potato industry, including potato producers directly south in North Dakota, have noted a substantial downturn in both boscalid fungicide efficiency and the wider group of SHDI fungicides in general, something that could rob them of one of their
