How it Works

Chlorothalonil 720F is a contact fungicide which attacks fungi pathogens at multiple sites, interfering with many metabolic functions within the fungi.

Being a FRAC Group M5 fungicide the potential for resistance development is extremely low.  This allows turf managers to use Quali-Pro Chlorothalonil as a rotational tool to control turf diseases and reduce potential of resistance development.
