Can I spray fungicide on wet plants?
Let’s take the question about applying a fungicide before it rains first. The short answer is that it is usually best to apply a fungicide before it rains. Why? Because rain causes leaf surfaces to be wet, a requirement for most foliar diseases, and rain may splash spores from leaf to leaf and from plant to plant.
What if it rains after spraying fungicide?
Rainfall that occurs less than one hour after spraying makes the fungicide pretty well ineffective.

For each additional hour between the spraying and rainfall you gain additional control.
