General Application
Authority® SC is a pre-emergence herbicide which is taken up through plant roots as they emerge through treated soil. Authority® SC may also be taken up through the foliage of plants which are present at the time of treatment.
Weed control occurs as a result of membrane disruption. Weeds will emerge and then turn necrotic soon after exposure to light. Adequate moisture (13 mm rainfall or irrigation) is required within 10 – 14 days of application to activate Authority® SC
Resistance Weeds Warning
Authority® SC is a triazolinone (Group E) herbicide. Excessive use of any herbicide may lead to the development of resistant weeds. Follow label directions and use in programmes with herbicides from a different action group. Consult http://resistance.nzpps.org/ for alternate modes of action.
