FAQs - Frequently Asked Questions

Essential oils have not worked for me in the past to fight diseases on my plants. Why does HydroWorxx work so well?

Copper is a broad spectrum, contact anti-fungal agent with little risk of fungi developing resistance. It breaks up proteins which disrupts enzyme systems, and prevents the germination of fungal spores. Copper has a long history of use as a fungicide supported by many studies on a wide variety of plants and fungal pests.

Looks like this product contains copper. Is it really safe to apply metal on my plants?

Fungi and bacteria are quite intolerant to copper but plants require a certain amount of this essential mineral. Copper is a micronutrient and is consumed in small amounts by plants from soil. HyroWorxx Disease Control decomposes to form soluble copper, and fatty acid, both of which can be used by microbes and plants. Because the copper in HydroWorxx Disease Control is in the form of a soap, it controls diseases using very low levels of copper.

Spray all plant parts thoroughly (top and bottom of leaves) just before the point of drip. Apply as soon as disease appears, or as a preventive spray 2 weeks before disease normally appears. If possible, time applications so that at least 12 hours of dry weather follows application. Repeat as needed, following the application directions and reapplication intervals on the label.
