To calculate the amount needed for band application, multiply the broadcast rate by the band width divided by the row width.Īfter you’ve calibrated the sprayer to know your application rate in gallons per acre, divide that number into the gallons applied with each tankful to find how many acres each tankful covers. You can reduce the amount of herbicide needed by as much as two-thirds by banding the application over the row and controlling the weeds in the middle with mechanical cultivation.įor example: A 3-pound-per-acre rate requires 3 pounds of herbicide for each crop acre in a broadcast application, but only 1 pound is needed to apply the herbicide in 10-inch bands on 30-inch rows. The application rate in the treated area should be the same for both the band and the broadcast application.

Herbicides may be applied broadcast (uniformly over the entire field surface) or in bands (narrow strips of herbicide centered over the row, with the area between rows left untreated).

Acid equivalent indicates the amount of an acid herbicide in a formulation. Herbicide rates may be given in terms of active ingredient or acid equivalent per acre treated, or as pounds or volume of commercial product per acre.Īctive ingredient indicates the amount of non-acid herbicide in a formulation.
