Oxadiazon 2G Pre-Emergent Herbicide (Ronstar)By Roger Dickson on 10/27/2015We were first introduced to Ronstar by a contractor who built a house for us in California. Home completed in October, construction grading left bare earth around our home. Landscaping to occur in the Spring.Our contractor warned us that weeds would pop up in the Spring and we wouldn't be happy. He recommended Ronstar. We purchased some and applied it per instructions. The following Spring - no weeds!That was 1990, and to date we have consistently used this product over the years with great success. A friend, who retired as a landscape Gardner at our state Capitol confided to me that they too use Ronstar for weed control.We now own a home in another state and Ronstar is a part of our routine there. It works on the lawn without destroying it and amongst established plants as well.Use of the product reduces labor and we've never paid a cent for a Gardner.We have been customers of Epest Solutions for several years now and find their price the cheapest and items shipped quickly....they've earned our respect and continued business.
