Abstract
Biopesticide compositions, and methods and kits for their preparation from lignin are disclosed. A biopesticide may include a modified lignin chelated with one or more pesticides, the one or more pesticides having at least one acidic pesticide. The modified lignin may have one or more functional groups. Methods of producing a biopesticide may include obtaining a lignin, contacting the lignin with one or more bacteria under conditions suitable for producing a modified lignin, and chelating the modified lignin with one or more pesticides, the one or more pesticides having at least one acidic pesticide.
