Abstract
The present invention relates to a pesticidal control device that includes at least one pesticidal active ingredient, cellulose fibers, and a polymer or polymer matrix. The combination of the cellulose fibers with the polymer allows for a higher loading of liquid pesticidal active ingredients within the pesticidal control device, maintains the active ingredient within the control device during transportation, storage and handling, and provides higher efficacy or control of pests during treatment. The pesticidal control device may be an ear tag, collar, or bee strip.
Claims20
A method of making a pesticidal ear tag comprising:
- a. mixing a polymer and cellulose fibers derived from wood pulp to form a polymer mixture;
- b. heating the polymer mixture;
- c. adding a pesticidal active ingredient to the polymer mixture;
- d. cooling the polymer mixture;
- and
- e. injection molding the polymer mixture to form the ear tag,
- wherein the cellulose fibers comprise from about 2% to about 20% by weight of the total weight of the ear tag.
