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.

Rotate crops and pastures

01

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

Double knock to preserve glyphosate

02

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.

Mix and rotate herbicides

03

Rotating buys you time, mixing buys you shots. Mix and rotate buys you time and shots.

Stop weed seed set

04

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.

Increase crop competition

05

Help your crops win the war against weeds by increasing their competitiveness against them.

Implement harvest weed seed control

06

Capture weed seed survivors at harvest using chaff lining, chaff tramlining, chaff carts, narrow windrow burning or integrated weed seed destructors.
