B from Waldorf, Maryland writes

According to the directions, Gordons Ornamec Over-The-Top Grass Herbicide must be applied when daytime temperatures are under 85 degrees. Is this for the day of the application, or several days before / after application as well? I am applying to Tall Fescue Lawn.

Answer:

As long as you do not apply the Gordons Ornamec Over the Top during the hottest parts of the day when temps would be 85 degrees or higher, it doesn't matter the surrounding days temperatures or the max for that day. If you treat in the early morning or late evening just before sun down, the plants will be under less stress and you will be able to apply it under their recommended temperature range.
