Common ragweed, giant ragweed and marestail, confirmed resistant to multiple herbicide sites of action in Ohio, are part of a growing group of yield-reducing “watch-out” weeds that are top of mind for farmers across the state.
“To keep these ‘watch-out’ weeds in check, farmers should plan to use a herbicide program that effectively targets the weeds using herbicides with different sites of action,” said Luke Bozeman, Technical Market Manager, BASF. “Incorporating a diverse herbicide program – along with identifying local weed pressures and reviewing previous weed escapes on a field specific basis – will help farmers build an effective weed management plan specific to their farm.”
According to the Weed Science Society of America, weeds cause more yield loss and add more to farmers’ production costs than insects, diseases, rodents, birds, and grazers, such as deer. Experts recommend farmers carefully manage any weeds — resistant or not — with herbicides that offer multiple sites of action, ensuring they don’t turn into the next crop of “watch-out” weeds.
Farmers that have utilized a herbicide program with strong, flexible solutions and multiple sites of action can attest to the benefits of planning for tough-to-control weeds.
“By using products like Kixor herbicide technology we can keep weed problems we’ve experienced at bay,” said David Roehm, Ohio grower.
The solution requires effort all season long.
“Proper weed management requires focus throughout the season,” Bozeman said. “Treat every weed like a tough weed and get it out of your field as soon as possible. Or better yet, never let it in.”
