I applied Prodiamine 65 WDG the day before a light rain shower was forecast. What we received was almost 2" of rain, some heavy at times. My home is on a slight incline and I'm afraid it washed away.
As long as the application of Prodiamine 65 WDG has had at least 24 hours without rain, there isn’t a need to reapply. We would recommend delaying the application if you’re expecting more than 1 inch of rain.
