Known as the “silver bullet” by growers around the world, Phyton 27 is a powerful systemic copper-based fungicide and bactericide trusted to prevent and cure plant diseases from the inside out. Unlike traditional copper sprays, Phyton 27 is absorbed directly into the plant and circulates through its vascular system—delivering control at the source of infection, not just the surface.

Whether you’re managing orchids, ornamental trees, or nursery crops, Phyton 27 offers broad-spectrum protection against common pathogens like botrytis, bacterial leaf spot, and powdery mildew—all without leaving behind residue. Use as a foliar spray or soil drench throughout the growing season, even on tender blooms and cuttings.

Phyton-27® is a systemic bactericide and fungicide labeled for a wide variety of ornamental plants, nursery crops and trees. Its unique composition goes beyond the traditional disease control of copper-based products without the traditional side effects. Phyton-27 works within the plant to provide integral disease control and often enhances overall plant health and vitality.
