Pea aphids love to feed off the sap flowing to new pods on the plant. The trouble is, just two aphids per plant at the right stage can siphon off as much as five per cent of yield. Laura Schmidt, production specialist with the Manitoba Pulse and Soybean Growers, says that modern pea varieties are... Read More

Grasshoppers are usually associated with dry conditions and go hand-in-hand with drought. And yet, grasshoppers are once again showing up in high numbers and causing crop damage in areas of the Eastern Prairies where there's been flooding, and more than enough rain and soil moisture for the first half of the growing season. Why is... Read More

Diamondback moths blow in at some point early in the season (thanks, America!), and set about living on the Prairies and in the canola crop for the rest of the growing season. Jordan Bannerman, entomologist with the University of Manitoba, says that understanding when the moths arrive, through the use of pheromone traps, and how... Read More

Grasshoppers are out there, and, in some areas in the Prairies, in large numbers. It's important to get into your field and scout, not only for populations, but also as a friendly reminder that not all hopping insects are grasshoppers. There are other insects in the field that hop and jump but aren't grasshoppers, says... Read More

When should you apply nitrogen on a corn crop and how much? That question consumes countless hours every year for corn growers, researchers, and agronomists. Seven years ago, Rodney, Ont., grain farmer Mike Miller, like many growers, was also playing the guessing game. But that all changed when he bought a self-propelled sprayer and started... Read More

Research shows plant growth regulators (PGRs) are most effective — and least likely to cause damage — when they're applied with precise timing, and that stage can pass quickly as a cereal crop develops. There are three questions to answer before applying a PGR, explains Anne Kirk, cereal specialist with Manitoba Agriculture, in this video... Read More

A soil pH outside the neutral range can cause significant issue with nutrient availability. Western Canadian soils are largely in this range, however, over time, nitrogen fertilizer applications can create soil acidity issues that are very expensive to fix. Dr. Manbir Rakkar, assistant research professor at Montana State University-Bozeman, explains that managing acidic soil conditions... Read More

Wheat harvest is underway in Ontario and many cash crop farmers are wondering whether they should plant those acres to soybeans and take advantage of double cropping. Double crop soybeans are always an opportunity for many growers, says AGRIS Co-operative agronomist Dale Cowan, but it's important to understand the risks. In 2021, he notes that... Read More

Timing crop protecting sprays is an important decision to make to ensure the health and quality of the crop. While sometimes weather conditions don't allow farmers to be as precise in timing as they'd like to be, there are some variables that should be taken into consideration when weighing the options of getting back out...

Andy Kieraszewicz never thought the sandy soils on the former tobacco land he farms at Rodney, Ont., could ever average more than 200 bushels of corn per acre. But a fervent commitment to rebuilding organic matter in the drought-prone areas across the 1,000-acre operation has the farmer now consistently producing eye-popping yields he didn't think...
