Reading Time: 3 minutes The past five years have definitely been on the dry side in Manitoba’s pea-growing regions — an important fact to remember when considering the results of Manitoba Pulse and Soybean Growers’ (MPSG) 2021 on-farm pea fungicide trials. That meant there was little disease pressure at the trial’s four locations (Roland, Swan River and two sites […] Read more
Scout first before applying a pea fungicide
Manitoba results indicate spraying for ascochyta blight was economic in fewer than one-quarter of trials between 2017 and 2021
The latest in herbicides and fungicides for 2022
More active ingredient combinations offered to control resistant weed biotypes
Reading Time: 5 minutes As weeds and diseases continue to evolve and overcome the active ingredients and modes of action of different herbicides and fungicides, the chemical industry must evolve to keep pace. The research and development challenges are considerable — it can take more than 10 years to bring a new product to market, and cost nearly $300 […] Read more
What’s up with fungicide resistance?
Resistance is hardly top of mind for most growers, but there are signs it should be climbing the ladder
Reading Time: 6 minutes Comparing resistance in fungicides to herbicides is like listening for a whisper above the noise of a pressure washer, or you could say the threat of disease resistance in major crops is advancing at a creep, not a run, as it is in weeds. Increasingly, though, that’s a challenge facing agronomists, advisors and those in […] Read more
Tracking tar spot in Ontario
Scouting is the foundation for managing this challenging new disease
Reading Time: 7 minutes In case you haven’t heard, tar spot in corn is finally part of the landscape in Ontario. Tar spot been plastered across the U.S. farm media for the past three years. Advisors, researchers and extension personnel in Ontario have been saying it’s inevitable that, given the diseases’s ease of transmission and rapid spread in the […] Read more
Focus on the ear leaf in corn production
Keeping the corn plant weed and stress free early allows the plant to form a larger cob, up to its genetic potential
Reading Time: 6 minutes It seems every growing season brings something new for growers to manage. Sometimes it’s a new disease or its anticipated arrival. Other years, it’s learning to cope with the impact of weather conditions, or a sudden weed flare-up. It’s a testament to modern agricultural science that the more we learn, the more questions we ask. […] Read more
Boost the N and boost the fungicide?
Study shows oat growers should make separate decisions on how much of each to apply
Reading Time: 3 minutes With the increasing demand for oats in the food market, growers these days are paying attention to both yield and quality, leading to questions about managing both nitrogen and fungicides. Does use of one affect how much you should use of the other? Not by much, according to research published this spring. Agriculture Canada crop […] Read more
Getting positive results from fungicide
Combining new technology with good agronomics helps result in a positive return from a fungicide application
Reading Time: 5 minutes The decision to apply a fungicide in any given year weighs the risk of damage from the disease against the cost of a fungicide application. As the risk for disease has spread across regions and crops, discussions on the economics of disease management can be heard on farms across Canada. But despite a rainy spring […] Read more
How to keep sclerotinia infection to less than five per cent
New research shows fungicide applied at or just after 20 per cent flowering is still the best way to stop sclerotinia stem rot from shredding canola profits
Reading Time: 6 minutes Like a detective piecing together the timeline of a crime, Dwayne Hegedus has played and replayed the sequence of events from when a sclerotinia-infested petal drops onto a canola leaf to the all-is-lost cleaving of the cuticle. The scientist with Agriculture and Agri-Food Canada in Saskatoon now knows, genetically, what arrows the pathogen shoots and […] Read more
Stay calm and spray on
A field guide to fungicide resistance management
Reading Time: 6 minutes Do you have questions about fungicide resistance? Have you ever wondered if that fungicide you used before is still working as it should? Are you worried about losing fungicide tools? Well, you’re not alone. “There have been a lot more questions about fungicide resistance in the last two years than in the last 10,” says […] Read more
Apply your fungicide where it matters
Climate FieldView is helping growers use imaging combined with historical data for a targeted approach to fungicide application
Reading Time: 4 minutes When it is time to make a fungicide decision, D’Arcy Hilgartner weighs several factors. Is the crop at the right stage? What are the current moisture conditions? How has the weather looked throughout the season compared to years past? How much of his crop is likely susceptible to disease? Today, he can access all of […] Read more
