You’ve scouted and know what weeds are present in your fields. You’ve paid attention to what weeds are prevalent in your region. And you’ve used an integrated management strategy that combines treating with the recommended modes of actions and using cultural practices like planting clean seed, controlling weeds along field edges and tilling to discourage weed germination.

I have had an evolution of views on herbicide resistance as it pertains to spraying. I’ve always believed that if you want to combat resistance with application technology, you need to spray less. After all, herbicide resistance is a direct consequence of relying too much on herbicide sprays.

Group 4 herbicides, synthetic auxins, were used on an estimated 366 million hectares globally in 2014. The top three modes of action are Group 9, glyphosate, at 508 million acres, then Group 2, ALS inhibitors at 477 million hectares, and then Group 4. We know that Group 9 and Group 2 have a lot of selection pressure for resistance, but what about the Group 4?

Integrated weed management requires as many weed control methods as possible. You try to prevent weeds from becoming established. Weeds can be controlled with tillage. Cultural weed control can be used by making your crop as competitive as possible. Biological weed control utilizes organisms that may be pathogens that kill the weeds. Rodents and insects eat weed seeds in your crop and can have a huge effect. Integrated weed management includes herbicides as well.

Resistance is an evolutionary process by which weeds evolve to become resistant to whatever tools we are using to control them. It’s my contention that resistance cannot truly be eliminated. We can’t stop resistance but we can manage it. We can extend the life of these weed control tools as long as possible, and in some cases a very long time if we do the right things.
