Will morning dew activate Tenacity when applied as a post emergent?

I read that Tenacity needs .15” of rain to activate within 10 days of activation. We aren’t expected to get any rain within that time but we have had morning dew every day since my application. Do I need to water my lawn anyway?


When using Tenacity Herbicide as a post emergent, it should not be watered in.  It should be applied when there is no rain in the forecast for 24 hours after application.
