Does anyone know how much asulox to mix with water to kill crabgrass in st augustine grass? I have a one gallon sprayer that I will be spot spraying with.
Thanks

1.5 oz per gallon, and use no surfactant

What is a surfactant? An also how long before a chemical like this would start killing?

surfactant can be any number of things added to a spray mixture for different purposes.as far as the time it takes to work, i dont really remember, but i think it might be something ridiculous like 2-3 weeks, and youll want to do two applications.

Two applications on the same infested spot I take it. Maybe after it starts browning. Then hit it again? By the way thanks for you responces.

time between applications should be no less than two weeks on any same area. oh, and most importantly, do not apply at temperatures greater than 85 degrees.
