The best time to treat with Hi-Yield Atrazine Weed Killer depends on if you are using a pre-emergent or post emergent application. For post emergent control it is best applied when weeds first start to emerge and are young. For pre-emergent it needs to be applied before target weeds geminate.. 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.
