Fungal diseases are one of the major causes of plant loss for greenhouse growers and home gardeners. Monterey Liquid Copper RTU puts an end to fungal pathogens once and for all. Even better, it controls the fungal diseases organically, so there's no worry about spraying toxic chemicals on ornamentals, houseplants, garden crops and other plants.

How Liquid Copper RTU Works

Liquid Copper RTU contains copper octanoate as the active ingredient. It's a copper soap used for the successful control of pathogens like powdery mildew, black spot and downy mildew. The copper penetrates the plant and creates a barrier against invading pathogens. It's used primarily as a preventive solution and will protect the plant when used as directed.

Monterey Liquid Copper RTU comes ready to use in a convenient spray bottle. Just point the bottle at the plant, and spray the solution. It's that easy.

Use it in both the dormant and growing seasons for thorough control of unwanted and devastating pathogens.
