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…

Flea beetles are just one thing to look for while scouting one to three weeks after seeding… -
Early weed control is preferred because nutrient and moisture taken up by weeds means less for the crop. Weeds emerging before the crop also compete for sunlight, which is an issue if those weeds canopy over the crop. Ideally, growers want crop emerging in a clean field so it can get ahead of the weed competition. That is why pre-seed… -
The rainfast requirement varies by product. Here are required intervals for each common product used in HT canola systems…

How do you spray weeds in a timely fashion when every day seems too windy? Too windy, according to the Guide to Crop Protection, is wind above 15 km/h. Here are tips for spraying in the wind… -
Growers will be eager to seed with the return of warm weather but early weed control also remains a priority — especially for fields that have not received any yet. Spraying those fields now and seeding three days later will have an economic benefit given that weed competition remains a major factor in crop yield potential… -
Seeding is the priority for many growers this week, but fields that still have lots of big winter annual weeds should get a pre-seed burnoff with a high rate of glyphosate before seeding… -
If choosing to seed before spraying, weeds present will have a minimum five days — usually more — before the crop emerges. These weeds can advance very quickly in good conditions, which is why growers who seed before spraying may choose to apply in the narrow post-seeding pre-emergence window… -
