Aaron Hager is standing in a resistant waterhemp hot zone. The soybean rows surrounding him are a blanket of five-way herbicide resistance: atrazine, ALS inhibitors, PPO inhibitors, HPPD ...

Waterhemp control is critical because the weed can cause significant yield loss and, when it is resistant to herbicides, also results in increased control costs, as much as doubling them.

Glyphosate-resistant biotypes of giant ragweed and common waterhemp have been confirmed within specific locations in Minnesota in 2007. Diversification with other herbicide modes of action via ...

Help can’t arrive fast enough for corn and soybean farmers who routinely battle Palmer amaranth (pigweed) or waterhemp, especially those with resistance to currently available herbicide ...

Findings from a newly published Weed Science Society of America research article demonstrates an efficient, mechanical way to control herbicide-resistant weeds The HWSC technology used for the ...

"These results indicate that seed impact mills can be a useful tool in soybean production to help manage multiple herbicide–resistant waterhemp populations." The HWSC technology used for the ...
