Quali-Pro MSM Turf Herbicide is best applied when rain is not expected within 24 hours after application. Since it rained hard during and afer your application, it has more than likely washed away the herbicide you just sprayed on. I would wait a day or 2 before reapplying just to be sure you don’t see any effects of the product in your lawn to ensure the product was completely washed away to reduce the risk of burn.
