Multisite enzyme inhibitor

Image of golf carts on path

Mancozeb, the active ingredient in Fore® 80WP Rainshield® specialty fungicide, is a multisite enzyme inhibitor that attacks fungi in a nonselective manner and prevents disease organisms from adapting and mutating.

Broad-spectrum control

The mancozeb particles in Fore 80WP are small and refined, so more fungicide remains on the turf blades — allowing broad-spectrum control of tough diseases like brown patch and black algae.

Even, consistent coverage

Technology of Fore® 80WP with Rainshield® technology allows for better distribution of active ingredient with fewer gaps in protection. This helps ensure more even and consistent coverage — even after heavy rain or irrigation.
