Big 6

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

This plan is all about the grower calling the shots, not the weeds. Download the Big 6 flyer.

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?

What’s better than an attack on weeds? A second one. Come at them with a different strategy and any survivors left over don’t stand a chance.

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.

Weedsmart Wisdom

While the Big 6 is a great framework for weed control options, we can’t fit everything in. In our WeedSmart Wisdom section, we focus on some of the other key principles for effective weed control, like spray efficacy and resistance testing.
