Product Overview

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.

Details

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.

Q
Is Ronstar G toxic to pets and children?

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?

A
Ronstar must only be used by commercial applicators and cannot be used on residential turfgrass. Applicators can apply Ronstar to landscape beds in residential areas. After the product has been applied, people and pets must wait until after the product has been watered in before they return to the treated areas. Ronstar is toxic to fish and other aquatic animals and should not be used in areas where runoff or direct application could enter the water.
