Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control. Reduced control may result when applications are made to annual or perennial weeds that have been mowed, grazed, or cut, and have not been allowed to regrow to the specified stage for treatment. This means the mixture of glyphosate is weaker as a percent of the solution. 27-Apr-12. Utilize the specified label rate for the most difficult to control weed in your field. Since the application rates and the pounds of active ingredient per gallon are identical for each formulation, the amount of active ingredient applied would be the same for each formulation. Ammonium sulfate reduces the antagonistic effect of hard water on glyphosate. The following good agronomic practices are specified to reduce the spread of confirmed glyphosate-resistant biotypes: This product may be diluted in water and applied through shielded sprayers, hooded sprayers, wiper applicators or sponge bars to weeds growing in any non-crop site specified on this label. For some situations a better approach to a single glyphosate application in corn and soybean is to utilize herbicides with soil residual activity.
