What the shelf life of Ronstar G Herbicide opened and unopened? Also in Southern California how often and when should you apply this product?

Answer:

According to the manufacturer, Ronstar G Herbicide has a shelf life of 3-5 years ( opened & unopened) if stored properly in the original packaging. The application of this product will completely depend on the type of weeds you are trying to prevent and the type of grass you are applying the product on and of course your location. The manufacturer also states that no more than 4 pounds can be applied in a single application and the product can be reapplied in 4 months. Please refer to the product label for more specific application instructions. We would also recommend that you contact your local cooperative extension office and speak to the master gardener on staff. He/she will be able to tell you the best time for the application as he/she will know when the weeds germinate in your region.
