  • Patent number: 5939089
    Abstract: A method of encapsulating a pesticide with an ultraviolet protectant comprises the steps of forming a slurry of a pesticide and a lignin-containing material, and spraying a stream of acid and the slurry into contact with one another to precipitate the lignin-containing material onto the pesticide and form a protective coating on the pesticide. The pesticide is preferably a biopesticide, and the lignin-containing material is preferably kraft lignin. The method is easily adapted to industrial processes currently used for pesticide production by simply changing the spray drier from a single nozzle system to a dual spray nozzle and then adding the acid stream to the dual nozzle.

  • Patent number: 5032164
    Abstract: Urea fertilizer is treated with a modified lignosulfonate to harden and provide anti-caking and anti-dusting properties to the fertilizer particles. The fertilizer/modified lignosulfonate mixture includes up to about 5.0% by weight modified lignosulfonate on fertilizer. An improved method of treating urea fertilizer with a modified lignosulfonate is also disclosed.
