Big 6

The WeedSmart Big 6 are a set of chemical, mechanical and cultural tactics to help growers control crop weeds.

It’s an integrated weed management program that growers can apply across all cropping systems. A diverse approach that includes several chemical and non-chemical tactics places downward pressure on the weed seed bank and reduces herbicide resistance risk.

This plan is all about the grower calling the shots, not the weeds.

Weeds love predictable rotations. They find it easy to evolve resistance to herbicides when they are used in a predictable manner.

Will longer crop rotations really help manage weeds?

Annual weeds must set seed if the species is to persist, so stopping weed seed set is a critical strategy to manage herbicide-resistant weeds.
