If weeds and crop are advancing toward the end of the application window and the ground is too soft and wet to support a sprayer, then aerial spraying may be the best economic response. Here are the options for aerial herbicide application in canola…

Many fields were seeded in odd shapes because low spots could not be reached. Growers have a challenge to manage the weeds in these patches. Options include…

Scientists at Agriculture and Agri-Food Canada are testing an early warning system for sclerotinia in canola. The project is in its first year and involves 35 volunteers in Saskatchewan monitoring the emergence of apothecia in 67 sclerotia depots across the province. Each depot consists of 50 sclerotia (fungal resting bodies) buried at the soil surface. Sclerotia in the depots are…

We had a “follow up question” to last week's article "Hail damage: Economic loss depends on cro stage." The grower was asking about foliar nutrition after a hail storm. He had 2” of rain a week after a hailstorm and he feels that a foliar application could be worthwhile. The hail hit canola at the 5-6 leaf stage with a…

Want to see how a foliar nutrient application helps a hailed crop? Leave a check strip. Want to see whether a novel treatment provided a return on investment? Leave a check strip. Growers can use strip trials on their own farms to test how a particular practice or product performs in a local environment. This information can then be used…

Two-hit wonder. Does your canola really need a second in-crop herbicide application? Only certain circumstances — like the one photographed above — make it worthwhile. Summer heat A new PAMI project will look into summer effects on stored canola, and help set best practices to prevent heating: Aerate to warm it, turn it to warm it, or just leave it…

In this week's quiz, we ask you to identify five weeds — including the one above. With the answers, we also provide useful agronomy information for each weed…

Growers who usually spray twice may not need that second pass this year if the canopy has closed, weeds are behind the crop, and the recommended application window is past. The crop should outcompete the weeds all on its own, and the economic benefit of the second herbicide application just won’t be there. But if the crop looks like the…
