  • Polymeric composite-pesticide plugs and related methods
    Patent number: 11116209
    Abstract: The disclosure relates to a slow-release biodegradable composite pesticide plug that can be used for trunk injection delivery of pesticides to protect woody plants such as trees (e.g., fruit trees) against pests. The composite pesticide plug generally includes a thermoplastic polymer matrix with a water-soluble thermoplastic polymer component, a cellulosic reinforcement, and a pesticide or other active ingredient. After injection into the tree trunk, the composite pesticide plug provides a uniform, relatively consistent dose of pesticide or other active ingredient to all parts of the tree throughout the growing season, thus reducing waste of material and cost. The biodegradable nature of the composite plug also enhances the healing of the tree after injection.
    Type: Grant
    Filed: March 13, 2018
    Date of Patent: September 14, 2021
    Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITY

  • Process for the preparation of maleated polyolefin modified wood particles in composites and products
    Patent number: 7605197
    Abstract: Wood particles or fibers and a maleated polyolefin are used to produce a composite in absence of a non-maleated polyolefin. The composite has properties enabling use in homes and avoiding the risk of formaldehyde based adhesives or other hazardous air pollutants.
    Type: Grant
