There are no restrictions or specifications on applying the Bayer Advanced Fungus Control for Lawns RTS before, after, or during applications of a pre-emergent, so you can apply it to a lawn that is dry or wet from dew or irrigation. We do not suggest applying it to overly saturated lawns or lawns that are experiencing an extreme run of heat/drought. Do not treat lawn during periods of stress from heat or drought. Do not apply when temperatures are greater than 85 degrees F, as injury to lawn may occur.
