100% humidity here in Florida but need to do a 2nd application of MSM to kill dollarweed in our St. Augustine grass. The grass is wet. Can product be applied on wet grass or do we wait?
MSM Turf Herbicide should not be applied if the grass is saturated or if there is standing water at the time of application. If the grass is damp from recent rainfall or even heavy dew it will not alter the efficacy of the MSM and you can apply it per the label instructions.
