Mix and rotate herbicides
Rotating buys you time, mixing buys you shots
- Mix two herbicides at full rates where possible
- Rotate between mixes, not just between individual herbicides
We have made a big fuss in the past over rotating between herbicides from one year to the next. This is still a good message, but an even better message, based on what we now know, is that mixing herbicides is even more effective than rotating between them. And combining the two messages is the best approach that growers and agronomists can take. What we mean by this is to mix two herbicides, both at full rates, and then rotate to another herbicide mix. Weeds find it easy to evolve resistance to simple, predictable weed control. Mix and rotate is neither simple nor predictable for the weeds.
The key takeaways:
- Rotate between herbicide modes of action.
- Mix different modes of action within the same herbicide mix or in consecutive applications.
- Always use full label rates.
- Incorporate multiple modes of action in a double knock e.g., glyphosate/Group 1/Group 2 knockdown followed by paraquat and Group 14 and pre-emergent herbicide.
- Test weeds for resistance to know what herbicides will and won’t work for you.
- In cotton systems, aim to target both grasses and broadleaf weeds using two non-glyphosate tactics in crop and two non-glyphosate tactics during the summer fallow, and always remove any survivors (2 + 2 & no survivors).
