Product Q&A

Answer:

According to the label, Simazine 4L Herbicide should be applied in late winter before the weeds emerge for control of summer annual weeds listed. So you want to apply when your soil temperatures have stayed at least 55 degrees for 5 days.   You may contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.
