Is Celsius really effective in crabgrass control when applied to St Augustine grass without destroying it?

I live in south Texas and have a big problem with crabgrass in my St Augustine...I use pre emergence in Feb. but I would have to continue this treatment every month because of our really never got cold enough to hold back the crabgrass as crabgrass reseeds... my mower is set on highest setting and I water 2 consecutive days a week to get roots down for lawn... nothing seems to work. Called you last year and nothing was on market to kill Crabgrass in St Augustine...that lotta money to pay for something.. and find out it really is not effective..tried other products to no avail..I need some help ..the surrounding properties all have crabgrass on 3 sides of my approx 15,000 sqft grass area and they could care less if they have crabgrass...I have purchased other products from you over time and usually have good results


Celsius is labeled to control crabgrass and can be used in St Augustine lawns but it is not for purchase on our site. Another comparable professional option would be Blindside or an Atrazine based product.
