Acrobat 50WP Available for Potato Late Blight

Marcia McMullen, Plant Pathologist, N. Dakota State Univ., Fargo, ND

BASF received EPA approval early this year for a new formulation of Acrobat fungicide for use on potato crops. Acrobat 50WP is a 50% wettable powder formulation with the active ingredient dimethomorph. The previous formulation, Acrobat MZ, contained dimethomorph plus mancozeb. The NDSU Extension 2001 Fungicide Guide did not contain the Acrobat 50WP formulation, as the Guide was published in December of 2000, prior to approval of the new formulation.

Acrobat 50WP can be used in a tank-mix with other fungicides, except mefenoxam or metalaxyl, and growers should refer to the respective tank-mix partner labeling for rates, methods, of applications, proper timing, restrictions and precautions. Rates of Acrobat 50WP for control of potato late blight vary with the spray interval and amount of disease pressure. For example, with a low disease pressure and a 7 day interval of spraying, the label indicates a 5 oz/acre rate, while with a high disease pressure and a 5-day interval of spraying, the label indicates a 6.4oz/acre rate. See label for further information.
