Hi Yield Triclopyr Ester works best when its used on plants that are actively growing and when soil temps are 50 degrees or higher at the time of the application. You would ideally want to apply it between 50 and 80 degrees. Be sure if you are spraying over lawns that you are spraying it on a tolerant turf species. We encourage you to contact your local cooperative extension office for specific timing in your area.
