Rains may not completely alleviate herbicide carryover concerns
Vince M. Davis, University of Wisconsin-Madison
This is just a reminder that while the excessive rain we’re experiencing is replenishing water in the soil profiles, it may not completely alleviate herbicide carryover concerns for compounds that are primarily degraded by microbial activity because the soil temperatures are still low and saturated. There are many discussion points that are still relevant in a WCM article:

This 12 page UWEX publication, referenced in the article, might be of particular interest. “Herbicide persistence and carryover”
