Dimension in Phx AZ

Each summer I have a crab grass battle. My lawn is over seeded with perennial rye in the winter, and is bermuda in the summer. Based on the Q&A, it seems as though applying Dimension now (Feb,) will kill my existing rye prior to the bermuda coming in (late April/May). If I were to wait until April/May, would it still be effective as a pre-emergent? It seems like crab grass would already be getting a foothold by then.

Answer:

Dimension 2EW needs to be applied before the seeds germinate in order for it to work properly. It is also labeled for early post emergence of crabgrass. It will likely not work as effectively if it is put down in April/May if the crabgrass is already out. We would recommend following the rule of thumb and putting the product down in early to mid February.
