Product Q&A

Answer:

If you had four inches of rainfall immediately after applying a pre-emergent such as Crabgrass Control Plus with Prodiamine, then it is likely you will have some uneven coverage due to puddling or runoff of the active ingredient. So unless you have perfect drainage in the treatment area - which most of us don't - you may see spotty control if product was washed away from some areas. You can retreat those areas as long as you have not exceeded the maximum annual rate for your turfgrass.
