Product Q&A

Answer:

If you are applying Prime Source Meso 4SC Select (Generic Tenacity Herbicide) as a post-emergent herbicide (to kill existing weeds), then you should wait at least 24 hours before watering the treatment area. If you are applying this product as a pre-emergent herbicide, then you should irrigate the application with 1/4" - 1/2" of water immediately after application for best results.
