Fall applied herbicides are a great way to reduce the weed seed bank, preserve moisture and nutrients, fight herbicide resistance, and give crops a better chance in the early growing season. Following a few best management practices can ensure your herbicide program goes even further.

Applying herbicides in the fall, however, can alleviate early-season pressure. Indeed, doing so can add distinct advantages to your growing program.
The cornfields that are most at risk for WBC infestations are those that are at pre-tassel to full tassel during peak flight of the female WBC moths. Female WBC moths preferentially lay their eggs on corn that has a fresh tassel. If they are at peak flight and a corn field is before or after tassel they will move on to another corn field or to a dry bean field.
