As we have seen over the past couple weeks, the weather in Iowa can change on a dime. According to NOAA, that variability will continue throughout the 2026 spring season. This can make weed management even more difficult- drier areas will have to be mindful of choosing herbicides with crop safety, and residual protection will be extra important for the areas that receive more rainfall. Dalton Webster, eastern Iowa agronomic services representative with Syngenta, said growers need to make sure their herbicide programs are flexible and robust enough to tackle any issues we see this crop season.
Webster said warmer temperatures could allow farmers to plant even earlier this season, so it’ll be important to start their fields clean and keep them clean with strong residual control.
Excessive rain can keep farmers from being able to make a planned pre-emergence application. Fortunately, Webster said a couple of their products- Storen and Acuron- are flexible enough to be applied post-emergence if weather delays get in the way.
Webster said Acuron and Storen work together to help corn crops emerge safely and keep rows clean all the way to canopy.
