Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees. Your target temperature range will depend on whether you are using Tenacity for pre-emergent or post-emergent applications. This is typically between 65-85 degrees. Please consult the product label for complete application instructions.
