I live in the D/FW metroplex. I have bermudagrass with lots of
crabgrass and broadleaf weeds. I want to get on a preemergent
program. I feel like this is the only way to effectively rid myself
of broadleaf weeds over time. I can't afford to hire a company, so I
was wondering what type of preemergents work. I have been looking at
Lesco, Vigoro and Green Light. Green Light is very expensive. Any
help would be appreciated.

Thanks
