Change things up this spring

March 13, 2017

Everywhere you look, someone is talking about the importance of resistance management when it comes to weed control. And at Nufarm, we’re going to do that too.

When weeds develop resistance to herbicides, it’s not something that happens mysteriously. We know why it happens and we know how to slow it down.

Did you know that every time you spray a herbicide, you’re likely creating small amounts of resistance to that herbicide? Every time you spray, a small percentage of the weeds in the field have natural variations that make them more tolerant to the herbicide you used. The number of weeds making up the small resistant percentage varies based on the number of weeds present, the herbicide used, etc.

Weeds are very adaptable and can find ways around the efficacy of herbicides. We can’t actually prevent weeds from developing resistance, but we can slow down the development of resistance.

Remember what you did the last time you were in a field, including the herbicide you used that created small amounts of resistance to it. The next time you go into that field, make sure you use a herbicide with a different mode of action.

Here are three things you can do this spray season to slow down resistance on your farm.

  1. Change it up. Do something different every year to throw weeds off their game. Weeds are smart but they thrive on routine so mix it up and mess them up.
  2. Rotate crops. Plant different crops and change up growing habits in your fields.
  3. Rotate herbicides. Use different modes of action and products with multiple modes of action. Rotate your tank mixes and change application timing.
