Devolopment of an alternative microencapsulated formulation of Command for use by cotton growers to reduce the potential for off-target movement of clomazone has been a priority and ongoing research and development program. A pilot commercial formulation, Command 2ME, was available to cotton growers in 1995. The use of this formulation by cotton growers in commercial situations demonstrated that the potential for off-target clomazone movement was substantially reduced in comparison to Command 4EC. The weed control obtained with this formulation was comparable to Command 4EC. However, problems associated with mixing and application suggested that this formulation was not of commercial quality. Continued research has developed new Command 3ME formulations which have been evaluated in small-plot university and company trials, and in commercial situations. These formulations have proven to provide reductions in the potential for off-target movement equal to or greater than Command 4EC applied pre-plant incorporated. Weed control studies have confirmed that performance is also equivalent to that obtained from Command 4EC. Mixing and sprayability studies have demonstrated that the Command 3ME formulation is of superior commercial quality. Command 3ME will be commercially available to cotton growers in 1996.
