Companion^® Biological
Fungicide WP

Companion^® Biological Fungicide Wettable Powder is a broad-spectrum biological fungicide for the prevention, control, and suppression of many soilborne and foliar diseases. It can be used for foliar and soil applications in nurseries, greenhouses and shadehouses.

Its active ingredient, Bacillus amyloliquefaciens strain ENV503, is a plant growth-promoting rhizobacterium that quickly establishes beneficial colonies on roots and leaves. It protects roots from invading pathogens, stimulates healthier roots, improves nutrient uptake, and triggers the plant's natural immune system through induced systemic resistance (ISR).

Companion Biological Fungicide WP works through multiple modes of action: it produces broad-spectrum antibiotic compounds that disrupt pathogens, competitively colonizes the rootzone, and activates the plant's systemic defenses. As a Group 44 biofungicide, it is a strong rotation and tank mix partner.
