Soybeans have been slow to canopy in multiple fields across Nebraska and growers have expressed concern regarding weed management (Figure 1). At sites where soybeans have a ways to go until they reach full canopy, producers are encouraged to include soil-residual herbicides with their post-emergence program; otherwise, additional post-emergence applications may be necessary.

Below you will find a list of herbicides with soil residual activity that can be sprayed in established soybeans to control weeds that are yet to emerge (Table 1). These herbicide options are effective on late-emerging, small-seeded broadleaf weeds such as common lambsquarters, common waterhemp and Palmer amaranth, and small-seeded grass species such as foxtails and barnyardgrass. Given current soybean growth stages ranging from 4^th trifoliate to blooming, First Rate, Outlook, Pursuit, Warrant and Warrant Ultra may be the options available to producers.
