Weeds

Volunteer canola that is done flowering will have already produced a large amount of viable seed. Unfortunately, controlling plants at this stage of growth will do little to reduce the viability of those seeds…

Herbicide labels say that glyphosate and Odyssey cannot be applied to canola after the 6-leaf stage and Liberty cannot be applied after early bolting. These limits are in place to ensure effective product performance and crop safety. Later applications can lead to reduced weed control due to advanced weed staging and reduced herbicide contact with the weeds through the increased…

Label application windows: Glyphosate: Anytime up to and including the 6-leaf stage of canola. Liberty: Cotyledon stage up to the early bolting stage of canola. Odyssey/Absolute: 2- to 6-leaf stage of canola…

Water stress can make canola more susceptible to herbicide damage. Damage can be enough to kill plants under extreme stress. Resist the temptation to increase herbicide rates if the crop is under stress…

Cereal crops in rotation provide canola growers will another opportunity to control cleavers, volunteer canola and other tough weeds to reduce the threat to next year’s canola. Volunteer canola control also reduces build up of clubroot and blackleg inoculum…

For weeds that do not "wet" easily avoid using very coarse droplets, and use high water volumes…

A water rinse is not usually enough to remove herbicide residue from the sprayer system. Herbicides can bind to the tanks and hoses, and most need water plus a cleaning solution to remove them. If not, you never know when the bound herbicide molecules will be released…
