  • Peroxy acid treatment to control pathogenic organisms on growing plants
    Patent number: 6238685
    Abstract: Both a process and a method of using peracid compositions, especially mixed peracid systems, to treat field or greenhouse grown plant tissue, seeds, fruits, and growing media and containers. The peracid can lower the natural, plant pathogen and human pathogenic microbial load resulting in less waste to molding, spoilage, and destruction because of pathogenic poisons.
