Wisconsin’s ag department is considering a special registration to allow a weed killer in sandy soils with restrictions.
The Department of Agriculture, Trade, and Consumer Protection is taking comments until March 15th on whether to allow expanded use of Linex 4L. The product is allowed on other crops in heavier soils, but DATCP says the registration pre-emergence use on potatoes as a five-year permit expired at the end of 2020.
Supporters say the registration would help potato growers control broadleaf weeds, especially common ragweed, and Eastern black nightshade, which has become a larger problem in recent years, particularly in the Central Sands area where pesticide options are limited.
