FAQ
Q: What's a DNA? And what makes Ronstar's mode of action unique?
A: Dinitroaniline (DNA) herbicides control weeds by halting root growth. But these products don't distinguish between weed roots and turf/ornamental roots, so they can inhibit turfgrass and ornamentals in treated areas. Another problem with these products has been herbicide resistance by goosegrass. Ronstar, on the other hand, contains the active ingredient oxadiazon, and is not in the DNA chemical class. Ronstar controls weeds through the shoots, not the roots. It does not harm turf and ornamental roots and is effective against DNA-resistant goosegrass.
Q: Is Ronstar effective on goosegrass and crabgrass?
A: Yes. However, it must be applied prior to emergence. Ronstar's performance is not significantly affected by temperature, and it will not lose its effectiveness if it's applied early. In fact, the opposite is true—an early application ensures excellent crabgrass and goosegrass control.
Q: Does Ronstar control Poa annua?
A: Yes. Just one application of Ronstar provides control that's equal to or better than other products registered for use on Poa annua.
Q: What's the best way to ensure effectiveness after Ronstar is applied?
A: Thoroughly water the treated areas soon after it's applied. Water only the soil and don't incorporate the chemical by raking; Ronstar works best when the soil surface is not disturbed.
