The recent heavy rains have resulted on lots of standing water and drown out areas in corn and soybean fields. Many of these areas will require replanting. A major consideration on whether to replant soybean in a field that was in corn is the rotational restrictions for corn herbicides. Table 22 (page 189-190) lists the rotational restrictions of the herbicides in the Weed Control Guide for Ohio and Indiana. The only herbicides labeled for use in corn which would allow replanting soybean immediately are Prowl and Python. All other soilapplied corn herbicides have a several month rotational interval which must elapse before soybean can be planted. Most of the postemergence herbicides have shorter rotational intervals, but would still require a couple of weeks before soybean can be planted.
