From the road, many fields look clean this time of year, but look closer. Weed seedlings are often present at high numbers, and these seedlings will only get bigger. Now is a good time to control them, especially as days and nights get warmer…

Seeding can begin fairly soon after a burnoff — but take note of the weeds present…
-
Growers who seed before spraying may want to apply in the narrow post-seeding pre-emergence window. But if that window is missed, early in-crop weed management is essential to hold yield potential. Some yield potential is likely already lost to weeds by that time…

While cleavers are a bigger issue in canola, given the competitiveness of the weed and the grade loss from weed seeds in the sample, growers have more options to effectively control cleavers in cereal crops. Effective cleavers management is best done with a whole rotation approach… -
Sprayer sitting uncleaned for a couple days in the pre-seed window could result in tank and plumbing residues that could come back to haunt the applicator when in-crop spraying starts… -
Step one in the pre-seed weed control plan is to see what weeds are present — annuals, perennials, winter annuals — and at what numbers. Choose a product based on which weeds present the biggest threat to yield based on their number and size… -
Around 90% of Canadian canola is exported, and our customers have high standards when it comes to clean seed, oil and meal. It is essential that all growers, agronomists and retailers do not use or promote unregistered pesticides or those with unacceptable residues. Here are three important points to follow before using a product on canola… -
Weeds may start re-growing and emerging sooner this year if the weather stays warm. The more weeds up and growing ahead of the crop, the bigger the return from a pre-seed burnoff… -
Lower temperatures and shortened days in the fall trigger perennials such as Canada thistle, dandelion and quack grass to start moving sugars to below-ground tissues. Winter annuals and biennials are also doing this, but they don’t need a cool temperature trigger. Spraying these weeds in fall takes advantage of this downward flow, providing better control for next year. Read more…
