Crop disease tags along on soybean’s coattails

‘Honeymoon’ period for producers is ending as diseases such as phytophthora root rot make inroads following soybean expansion

Glacier FarmMedia – The worst phytophthora infection that Laura Schmidt of Manitoba Pulse and Soybean Growers has ever seen was just south of Souris. “Probably 25 per cent of the field was impacted,” the production specialist told field day attendees at the Westman Agricultural Diversification Organization near Melita. “One in four plants were dying off, […] Read more

During the billions of years, where plants and bacteria co-existed before the arrival of humans, the two groups learned how to cooperate and live in synergy. That co-operation is still happening in 2024. | Getty Images

Plants and bacteria: friends for 500 million years

WINNIPEG — Bacteria have been on earth for much longer than humans. The first ancestors of humans with the ability to walk on two legs arrived about four million years ago, says the Smithsonian Museum of Natural History.

Adding biologicals to the soil doesn't always work in the field, so a better approach could be altering the plant genome to work in synergy with soil microbes, says a plant scientist and soil microbiology expert from the University of Kansas. | Getty Images

Microbiome revolution proposed

WINNIPEG — The hyperbole around biologicals and what they can do for crop production sounds like 10 million crickets in a suburban backyard. There’s a lot of noise around biologicals, and for good reason. Soil contains millions of bacteria, fungi and other microbes that perform vital functions for plants. As a result, global agri-science firms […] Read more

The gaps in Palmer amaranth, waterhemp prevention

No one wants Palmer amaranth or waterhemp to become bigger weed worries than they already are in Manitoba, and there’s work currently focused on making sure that doesn’t happen, but locally based knowlege is still thin on the ground. The two boogeymen of the weed realm were recently the subject of a successful resolution brought […] Read more

While a research study found that few commercially available biological nitrogen-fixing products work, scientists remain hopeful that the challenges facing this technology will one day be overcome.  |  File photo

Biological nitrogen-fixing products fail test

WINNIPEG —Dave Franzen is a straight shooter. If he doesn’t know the answer, the North Dakota State University soil scientist will admit it. If he does, he’ll tell you. As an example, in the summer of 2022 researchers from land grant universities across the north-central United States studied commercially available, biological nitrogen-fixing products to see […] Read more

Should I spray or should I go?

Deciding on a fungicide application to control mycosphaerella blight (aka ascochyta blight) in field peas can be difficult. Many variables are at play, including disease occurrence, product selection, application timing, single versus double treatments, application costs and potential returns on investment. To help, a fungicide decision worksheet is available to take some of the guesswork […] Read more
