OMRI approved, Purshade-O® is the industry’s top-performing organic plant protectant for preventing the damaging effects of solar stress. Based on superior materials and engineered with Advanced Reflectance Technology™ (ART™), Purshade-O protects plants from damaging UV and IR radiation while still allowing photosynthesis to occur. No other organic formulation compares with Purshade-O’s ease of use or effectiveness at reducing sun damage and promoting plant health. Incorporating calcium-based Purshade-O into a planned spray program helps organic growers maximize return from every acre planted by increasing yield potential, enhancing crop quality, and improving water use efficiency.
Superior Performance … Proven Results
Tested and proven, Purshade® protectants have been shown to:
- Increase marketable yield up to 30% by reducing cullage and promoting the production of higher yields.
- Reduce sun damage by as much as 40%, as well as improve crop quality with larger fruit and/or better coloring.
- Reduce plant stress by 20%–60% and in turn improve the plant’s use of available water resources.
Superior Protection … Tested in the Lab and Proven in the Field
Scientifically engineered with Advanced Reflectance Technology, patents-pending Purshade solar protectants have been shown to:
- Reflect 85%—95% of harmful UV radiation, without blocking photosynthetic light.
- Keep plants 7—10 degrees Fahrenheit cooler by reflecting IR heat. This reflectance reduces stress on plants and enables basic physiological processes to continue in high temperatures when they would normally shut down.
- Shield crops with SPF 45.

Superior Formulation … Preferred by Growers
Designed with growers in mind, the Purshade family of solar plant protectants come in a patents-pending liquid formula that was specifically formulated to:
- Provide uniform distribution and even coverage.
- Be applied with most fungicides and insecticides using typical ground or aerial sprayers with standard nozzles.
