Rotating buys you time, mixing buys you shots. Mix and rotate buys you time and 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 or predictable for the weeds.
