When is it too cold to spray or to have it work, even at night?
When using Grass Out Max (Clethodim Herbicide) label states that it will be most effective if applied at higher than 47 degrees but not exceeding 80 degrees or crop injury may occur. Best to apply during the day so the application has enough time to dry before night fall.
