If you are not supposed to apply this product at 85° or above for the whole day why are you selling this product in the South ?

Lawn fungus does tend to be a problem in the south as they do thrive in hot humid conditions. If you are experiencing high temperatures in your area it may be possible to apply very early in the morning or later in the evening. The temperatures do need to be under 85 degrees at the time of application and until allowed to dry completely to avoid harm to grasses. Jessica
