Best broadleaf pre-emergent for the midwest?

:confused:Still very new to using pre-emergents. Last year the only one we used was what was in our first step of our fert. program then used post-emergent after that. I'd like to get something down on my customers lawns that will cover a wide range of broadleaf, and I'm not sure what to use. Located in the St. Louis area. What/when should I apply?

Really only pre for broadleaf weeds in isoxaben (Gallery) Usually only used in beds because it is so costly. ~$150/lb Coverage is 1 acre depending on rate (can't remember how much) If you spray broadleaf weeds at the right time & thicken up the lawn, broadleaf weeds shouldn't be a problem....

Yes, BROADLEAF preemergents really don't exist for lawn use, or the ones that do aren't all that effective or are far too clostly. Plus, you would really need to apply it in the fall to have control on them, as most germinate over winter, or at the least before you are out putting down the first application in the early spring.

Most broadleaves are best sprayed with a post emergent herbicide.

agreed, if you control the early weeds b4 they can seed, and have thick turf, weeds will not be an issue. thick healthy turf is the best defense against weeds
