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… -
The longer a herbicide sits in a sprayer, the greater the risk that it is going to hang up in the tank. Sprayers should be cleaned at the end of every work day regardless if the same product or tank mix is being sprayed the following day…

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… -
Applying a burnoff after seeding but before emergence is a risky option for those who want to get seeding. Consider the following risks with this practice…

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… -

No time to wait? Growers who want to do a preseed burnoff and then get seeding may not want to wait 3-4 days for the weeds to recover from a frost. In this situation, growers should recognize that if they go ahead and spray right away, efficacy may be reduced. However, even with the lower efficacy, doing the burnoff and…
