Early bird may dodge verticillium woes in potatoes

Pushing a problem field to the front of the planting queue may help limit infection

By
Verticillium wilt is a problem for a lot of crops in Manitoba, including canola, sunflowers and alfalfa. In potatoes, the fungus Verticillium dahlia is the main cause of potato early die complex. In a 2021 interview with the Co-operator, Mario Tenuta, University of Manitoba soil scientist and main investigator with the Canadian Potato Early Dying Network, suggested the condition

Do you know your trade MRLs?

Pre-harvest is the time to protect the crop’s marketability for international markets

By
Maximum residue limits can affect the marketability of a crop, so farmers need to heed them, say crop market experts. “Because we produce so much beyond what we need for our domestic demand for food, we really do need to keep in mind market access and those requirements that we see with our export partners,”
“When you’re looking at the sprayer, how it’s physically put together in terms of the structure and how it’s operated, we want to understand how that impacts the potential for spray drift.” – Lorne Grieger , PAMI.

Air disturbance from the sprayer itself may be affecting your drift risk

By
We’ve come a long way with sprayers. We’ve made them bigger, we’ve made them faster and with new visual technology and artificial intelligence, we’ve even made them smarter. Now, research by the Prairie Agricultural Machinery Institute (PAMI) along with the College of Agriculture at the University of Saskatchewan and Agrimetrix in Saskatoon is asking, ‘Can

Genetic attack cutting edge of sclerotinia fight

Hacking messenger RNA can prevent fungal disease from propagating

By
Most pesticides work by getting into a cell and disrupting its working parts or pathways. By applying the right chemistry at the right time you can shut down a pathogen’s engine and bring it to a stop. But despite all the available chemistry, sclerotinia always finds a way to keep driving around untouched. Mark Belmonte,

Adjusting to the new fungicide reality

Broad spectrum fungicides are increasingly off the table for potato production

By
Potato producers have seen their last year for the old label of mancozeb. The grace window given to the multi-site contact fungicide by Health Canada ran out as of November 2022. The fungicide has been “a staple in the industry for fungicide use,” said Dan Sawatzky, manager of the Keystone Potato Producers Association. “I think there are other

Turns out plants can recruit bacteria to fight pathogens

Researchers find corn somehow attracts fusarium-fighting bacteria

By
Glacier FarmMedia – Researchers have found corn silks naturally contain diverse microbes, a finding that may point to a new strategy to help protect cobs from fungal infections. The normal function of silks is to facilitate seed formation, as sperm, when released from pollen, will travel up the silk to fertilize the egg. This also creates a

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

Mancozeb fight calls potato growers to share on-farm use

Spud growers urged to share info on mancozeb

By
Mancozeb is on the regulatory chopping block. Now Manitoba potato producers are being urged to share how they use the chemical as their industry attempts to preserve it as an aerial fungicide, and they have just days to do it. Why it matters: Health Canada has proposed a ban on mancozeb for potatoes and other

Running down the risks of seedling disease

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
