I find these two statements to be contradictory. If it's rainfast within 4 hours, why does it matter if it rains after four hours?
As with any product applied outside, environmental factors can play a role in how soon an application is rainfast. It all depends on how soon the area treated dries really. If there is a lot of sunlight to the area and not a lot of humidity this could be within 4 hours. No rain within 24 hours is recommended just to be safe after an application of Garden Tech Daconil Fungicide Concentrate.
