Application Tips

• To ensure excellent crabgrass and goosegrass control, the earlier the applications of RONSTAR^®, the better. Ronstar is a true pre-emergent herbicide that must be applied prior to weed seed germination. The performance of Ronstar is not significantly affected by temperature, and Ronstar will not lose its effectiveness if it is applied early.
• An effective tankmix option is combining Ronstar* and FINALE^®. This combination has a number of benefits:
  • Controls a broad spectrum of annual broadleaf and annual grass weeds.
  • Controls existing weeds and prevents new weeds from emerging.
  • Can be used in hard-to-maintain areas, such as around fence posts and trees.
• Ronstar is not registered for use on home lawns
