Crabgrass is crapgrass and here in Pueblo , at work we use Trimec Plus not Trimec Crabgrass and at home I use Fertilome. They both are extremely effective here, so much so ,that we use it less with each passing year.
I understand that this site is meant to be helpful to anyone who asks and that is what I offered, help. I don't know if we have that type of grass here but if we do both of these products will work, if not, then I at least offered.
