While swathing or straight combining, keep an eye out for weed escapes. Unless they are an obvious sprayer miss or are weeds not well controlled under the herbicides used on the field, they could be herbicide resistant weed patches…

Growers considering a pre-harvest glyphosate cannot apply it to canola (RR or non-RR) until seed moisture drops to 30% or lower. This roughly coincides with 30% seed colour change. Spraying earlier raises the potential for glyphosate residue in seed. Pre-harvest glyphosate will kill green weeds and even out the non-RR canola for straight combining. Group-14 Heat can now be used…

Crop staging comes into play for herbicide, insecticide and fungicide timing. So crops with plants at various stages — some at flowering, some barely at the bud stage, for example — present a challenge when deciding when to spray…

Combining pest control operations to save trips over the field may seem like good economic sense, but consider the following when making this decision…

(1) Many insecticides have limits on how many times a year they can be sprayed on a canola crop. (2) Check approvals for all products to be used on canola…

The first few weeks of the growing season is a great time to police fields for suspicious weeds. Look for weeds that lived through the pre-seed burnoff or post-emergent sprays while others of the same species have died. These few weeds could be resistant to one or more herbicide groups, and it would be good to nab them early. Diversification…

Crop diagnostics often come down to good photography skills, especially since so many people have smart phones with cameras, and since agronomists cannot get to all fields in a timely manner. The rules to agronomy by phone and photograph are…

Hit these volunteer canola plants when they're small with a pre-seed burnoff. Volunteer canola is a weed and competes with the crop for nutrients and water and sunlight. Volunteers do not have seed treatment, so they can introduce seedling diseases and increase flea beetle pressure. Also, volunteers in non canola years provide a host for blackleg, clubroot and insects, reducing…
