Mix It Up & Make an Impact

Rotation of crops, tank-mixing multiple effective modes of action, and the inclusion of mechanical and cultural control methods where possible, can play important roles in delaying and managing resistance. Together we can champion stewardship and our actions will shape farming for years to come.
Let’s make an impact, together. Let’s start today. Let’s Mix It Up.

TANK MIXING
TANK MIXING TANK MIXING

One effective way to delay or manage weed resistance is to use herbicide tank mixes with different modes
of action.

Weeds are composed of various biotypes that differ in their resistance to certain herbicide Groups. If the same herbicide Groups are used repeatedly on the same field every year, then the biotypes which are resistant will remain in the field. Tank mixing multiple effective modes of action to control the same weed biotype is essential in combatting resistance.

Mixtures Work Best

Research has shown that tank mixes are more effective at delaying resistance than herbicide rotations.

A 4-year study* comparing resistant weed populations when rotating herbicides versus tank mixing herbicides, showed that applying tank-mixes every year was as effective as never having applied a herbicide in delaying resistance. By contrast, only using the herbicide once in those four years significantly increased the resistant seed bank. The benefits of a tank mix couldn’t be clearer

Crop Rotation

Diversify Your Crop Rotation

Annual crop rotation adds diversity, which increases the sustainability of the cropping system over time. It provides the platform for long-term crop management solutions meaning a well-planned crop rotation can:

Reduce the impact of weeds, insects, and diseases, leading to higher yields

Crop Rotation

Tackle Glyphosate Resistance

On the surface, trait rotation may seem like an effective way to manage glyphosate resistance. However, relying on trait and herbicide rotation alone is an ineffective approach to long term sustainable glyphosate use. Rather, use herbicide mixtures or herbicide layering every year within a diverse crop rotation to effectively manage weeds. Including wheat, barley, or pulses in a rotation provides more herbicide options and can decrease herbicide resistance risk.

Crop Management
Crop ManagementStart with Clean Fields
  • If tillage is an option, the mechanical weed control of this process adds another tool to your toolbox If tillage is not an option, take advantage of a pre-seed application.
  • It is your easiest opportunity to include a tank mix in your herbicide program and control weeds from the start.

  • Match the right herbicide based on your most difficult weeds
  • Apply multiple herbicide Groups that are effective on target weeds

  • Seed competitive varieties and increase seeding rates to enhance a crop’s ability to compete more effectively with weeds
  • Vary seeding dates and decrease row spacing

  • Use full-labeled rates, including the correct nozzle spacing, droplet size, and water volumes
  • Avoid spraying at excessive speeds and apply during the best weather conditions
  • Make sure your equipment is properly calibrated
