An Investigation of the Colorimeter as a Means of Evaluating Hydraulic Agitation of a Wettable Powder Herbicide

The purpose of this study was to investigate the use of the colorimeter as a means of determining the characteristics of hydraulic agitation of a wettable powder herbicide in a water diluent.

The availability of information concerning the agitation characteristics of a wettable powder would be important value in determining the minimum requirements of the agitation system. The development of this technique would also be of great value in the design of new formulations.
