Crop rotation is great for farming systems! Make sure weed management is part of the decision when planning crop rotation.
Crop rotation offers many opportunities to use different weed control tactics, both herbicide and non-herbicide, against different weeds at different times.
Rotating crops also gives us a range of intervention opportunities. For example, we can crop top lupins/pulses, swath canola, and delay sowing some crops (like field peas).
Rotations that include both broadleaf crops, like pulses and oilseeds, and cereals allow the use of a wider range of tactics and chemistry.
Growers also have the option of rotating to non-crop e.g. pastures and fallows.
Northern growers can rotate between summer and winter crops to change the weed spectrum.
Within the rotation it is also important to not repeatedly use herbicides from the same mode of action (MOA) group. Some crops have less registered herbicide options than others so this needs to be considered too, along with the opportunities to use other tactics in place of one or more herbicide applications, such as harvest weed seed control.
Repeated use of herbicides with the same MOA is the single greatest risk factor for herbicide resistance evolution.
