Herbicide carryover isn’t something farmers have to worry about too often. But this season could be an exception for areas of the Midwest that have been dry since fall, especially west of the Mississippi River.
“Temperatures and moisture have the biggest influence on the breakdown of chemicals,” says AgriGold Agronomist Jason Mefford. “Last spring we saw a fair amount of herbicide carryover after the drier 2022 season. And we are much drier heading into the 2024 growing season.”
Farmers need to have herbicide carryover on their radar and be ready to make adjustments that limit their risk.
Identify at-risk fields
Start by determining which fields are most at risk of herbicide carryover, Mefford advises. That largely hinges on soil type and the chemistry used.
