ProStar 70 WG Fungicide treated areas can be irrigated safely after 24 hours from application. The 24 hour wait time recommneded per the product label regarding rainfall or irrigation is to ensure the application has adequate amount of time to dry to avoid any runoff, draining or puddling that may occur with additional rainfall or irrigation. The only lawn disease where irrigation is recommended immediately following the application is Fairy Ring.
