Late weed control significantly increases the yield loss from weed competition, and it can also damage canola plants. However, the yield and economic risks from a later in-crop spray could make sense... —If growers use canola as a clean up crop for Group-1 resistant wild oats, narrow-leaved hawk’s beard, round-leaved mallow and other tough weeds, a second herbicide application may…

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…
