Ronstar G is for commerical applicators only
NOT FOR USE ON RESIDENTIAL LAWNS & TURF
Ronstar G is a pre-emergent herbicide that controls a variety of annual broadleaf and annual grass weeds. Offering a conducive environment for sprigging, Ronstar controls weeds through their shoots rather than their roots, so it won't harm turfgrass roots in the process. In fact, Ronstar can be used for long residual pre-emergent weed control even in areas that may need to be sprigged or where turfgrass roots are already weakened due to pest, mechanical or other damage.

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 (annual bluegrass)?
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.

If so, how long should the treated area be off limits? If the product was to enter a water source such as a pond, is it toxic to the fish?

How much water is required/sufficient to water this in? Will product still be visible on the surface of the dirt if properly watered in?
Be sure the you irrigate at least 1/2 in of water after Ronstar G - 50 lbs. application. The water will activate the granule, and then it should no longer be visible.

You can apply a fertilizer either right before or right after applying RonStar G, you just cannot apply them together at the same time.
