Winter annual cleavers are reported in high numbers in some fields. These need to be sprayed before seeding to prevent them from getting really large and near impossible to control with in-crop label rates. The pre-seed window provides an opportunity to hit these large cleavers with rates needed for control…

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…
-
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…
-
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…
-
If a burnoff didn't get done or missed key yield robbing early season weeds such as quackgrass and dandelion, then control has to be early in crop to prevent significant yield loss. For quackgrass in particular, in crop control may require a tank mix with good activity on grasses…

Early weed control is an important step in profitable canola production. Research on preseed weed control showed that early seeding was less important to yield than early weed control. Pre-seed weed control will manage weeds that emerge ahead of seeding, reducing crop competition for light, moisture and nutrients…
