Product Information

Agrisel Biophos Pro Fungicide

Agrisel Biophos Pro Fungicide is a systemic fungicide that is quickly absorbed by plant foliage.

It controls such diseases as downy mildew, powdery mildew, greasy spot, Phytophthora, greasy spot, late blight and more.

Mode of Action

Agrisel's Biophos Pro Fungicide belongs to the phosphonate class of fungicides. There are two professional opinions of its mode of action.

The other group maintains that it affects the fungus by stimulating the natural host defenses to prevent the disease.
