Management application:
Adding ammonium sulfate (5kg/ha) or phragmites to the solution prepared for spraying increases the absorption property by weeds. This poison should be used for spraying only once a year and the continuous use of this poison should be avoided due to possible risks for the next crop. In the last year of alfalfa cultivation, its consumption should be avoided.
