Chlorothalonil provides broad-spectrum control of foliar diseases including leaf spots, blights, and mildews in numerous crops. Its multi-site activity makes it effective against many fungal pathogens simultaneously.

By affecting multiple biochemical pathways in fungi, Chlorothalonil presents minimal risk of resistance development compared to single-site inhibitors. This makes it invaluable in resistance management strategies.

Yes, it's compatible with many commonly used pesticides, but always conduct a jar test before mixing large quantities. Follow recommended mixing orders and avoid combinations with alkaline products.

Applicators should wear chemical-resistant gloves, protective eyewear, long-sleeved shirts, long pants, shoes plus socks, and potentially a respirator depending on application method and duration.

While reasonably rainfast once dry, heavy rainfall shortly after application may reduce efficacy by washing product off leaves. Reapplication may be necessary after significant precipitation events.
