I have found that Tenacity has a max temperature for application at 80deg F. Most others top out at 90deg F.
Pylex Herbicide should not be applied during the day when temperatures are above 85 degrees. Applications should be made in early morning or evening when temperatures are at the lowest for the day. Although the product label does not give a specific temperature for being too cold, most herbicides should be applied between 65 degrees and 85 degrees.
