Pesticidal control device with high load of active ingredient

摘要

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.

主权项

1. A molded pesticidal ear tag comprising:
a. a pesticidal active ingredient, wherein the pesticidal active ingredient is selected from the group consisting of an organophosphate, pyrethroid, carbamate, nicotinoid, organochlorine, pyrrole, pyrazole, oxadiazine, macrocyclic lactone, and combinations thereof; b. a polymer; and, c. a cellulose fiber present in an amount of from about 5% to about 15% of the total weight of the ear tag, and wherein the molded pesticidal ear tag is in the form of a composite having the pesticidal active ingredient, polymer, and cellulose fiber homogeneously distributed throughout.
