What is the product?

Ronstar® Turf and Ornamental Herbicide is a unique and proven pre-emergent herbicide, with a novel mode of action. With its foliar uptake activity, it is unlike any other pre-emergent herbicide in that it does not have any impact on root development. This provides Ronstar with excellent properties for being used in containerised plant situations and in turf establishment. In addition, Ronstar is the standard in turf pre-emergent herbicides for crowsfoot control and with its Group G mode of action plays an important role in rotation management to avoid resistance of key weeds.
