Ronstar is a herbicide that offers great weed control without root pruning. This selective, granular, pre-emergent herbicide controls certain weeds in woody ornamental shrubs and trees in nurseries.
It can also be used on a wide range of turf species. It does not affect root systems, offering a flexible approach to effective, economic weed control, giving faster plant establishment and growth.
Using a residual, pre-emergent herbicide can eliminate the need for multiple post-emergent herbicide applications.
