Ronstar FLO Herbicide - 2.5 Gallons
Ronstar FLO Herbicide
Ronstar FLO is a pre-emergent herbicide for the control of annual grasses and broadleaf weeds in turf and ornamentals. Ronstar herbicide controls weeds through shoots, not roots. So unlike competitive products that don't distinguish between roots of weeds and roots and desirable plants, Ronstar doesn't harm healthy turf. This product can be applied to sensitive grasses and areas where roots are already weakened by winterkill, pests or injury.
- Works on warm-season grasses.
- One pre-emergent application - even in cold weather, or weeks before seed germination - controls weeds all season long.
- Offers an environment conducive to sprigging.
- Doesn't inhibit turf root growth or recovery from damage.
Doesn't prevent roots from tacking down.

Remove existing weed growth before application. The maximum number of applications is 2 per year. A subsequent application can be made 4 months after previous treatment.
