Emerging Soybeans and Delayed PRE Herbicide Applications

Soil-residual herbicides are important components of integrated weed management programs. Labels of many single and multiple active ingredient products allow application before and after soybean emergence, but other active ingredients can cause severe soybean injury if applied to emerging soybean. In fields where a PRE herbicide application has been delayed and soybean are beginning to emerge, the following active ingredients (applied either alone or as a premix product) should not be applied:

sulfentrazone (many Authority-based products, for example)

flumioxazin (many Valor-based products, for example)

metribuzin (TriCor, a component of Boundary, for example)

pendimethalin (Prowl H₂O, for example)

salfufenacil (Sharpen, Zidua Pro, for example)

linuron (Lorox, for example)
