Abstract
This invention relates to the field of control of different fungal diseases in the agricultural industry. Specifically, the invention reports conjugates between biopolymers and a photoactivable agent, which when activated by light generates singlet oxygen, a species known for its antimicrobial capacity. The invention also relates to methods of production of these conjugates and their uses.
Claims17
A fungicidal composition for inhibiting growth or combatting fungal infections of fungi of the genera Botrytis, Penicillium, and Rhizopus, the fungicidal composition comprising a biopolymer selected from the group consisting of chitosan, poly-lysine, alginate, and cellulose, conjugated to a photoactivable agent selected from the group consisting of riboflavin, porphyrins, phthalocyanins, naphthalocyanins, chlorines, phenothiazines, acridines, and 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY),
- wherein the photoactivable agent generates oxygen radicals when activated by natural light.
