AI Technical Summary
Existing copper-based fungicides require large doses for the control of plant diseases, leading to heavy metal pollution and environmental risks. Furthermore, multiple diseases require the simultaneous use of multiple fungicides, increasing costs and pesticide residue risks. Cuprous hydroxide fungicides have not been reported and are unstable, making long-term storage difficult.
A cuprous chloride coordination compound is stirred in water to form a cuprous hydroxide suspension. Its stability over a certain period of time is utilized as a bactericidal liquid to control oomycete, fungal, and bacterial diseases. Surfactants are added to enhance stability and wettability.
It achieves broad-spectrum control of various plant diseases with low copper content, avoids the risk of heavy metal residues, simplifies the application process, and is more effective than traditional fungicides, meeting organic cultivation standards.
