Weed Control Challenge

Perennial dandelions have proven to be a very tough weed to control, especially at burndown. They not only compete with your cereal crop…that bright yellow colour taunts you, as if to say, “Hey everybody, this is one dirty field!” So how do you control dandelions and other tough weeds that elude a straight glyphosate burndown?

Nufarm Solution

KoAct is an innovative new add-in from Nufarm. It is proven to be effective at controlling dandelions when they’re most vulnerable during spring or fall burndown. In addition, KoAct provides enhanced control of volunteer canola (including glyphosate-tolerant biotypes), even at advanced staging.
