Blazer and Storm and tank mixtures of these herbicides with 2,4-DB provide excellent control of common ragweed. As is the case with all postemergence herbicide treatments timely application to small weeds and good spray coverage is critical in obtaining good common ragweed control. Good to excellent control of both species is obtained with soil incorporated treatments of Prowl or Sonalan. Dual, Lasso and Frontier provide suppression to control of broadleaf signalgrass but are ineffective for control of Texas panicum. Postemergence treatments of Poast or Poast Plus effectively control either species.
Select herbicide is pending registration for postemergence control of grass species in peanuts.
Select may receive registration for use on peanuts for the 1998 growing season. Select provides effective postemergence control of both broadleaf signalgrass and Texas panicum. Cracking stage treatments of Starfire and early postemergence applications of Cadre are additional options which provide good to excellent control of these species. Starfire and Cadre are good options to improve control of these grasses in situations where the less than complete control is achieved with grass herbicides which normally control these weedy plants. Most peanut fields will require postemergence herbicide applications to achieve good season long weed control.
