Problems solved by technology

Ear tags such as those described in U.S. Patent No. 3,731,414 are subject to cracking and wear due to their size, design, and method of attachment causing parts of the tag to experience flex and stress over time
Additionally, the inclusion of active ingredients or active ingredient mixtures that actually weaken the polymer matrix can lead to cracking or embrittlement of plastic labels

[0017] Preparation of One-Component Ear Tags or Collars

[0018] A. Dry blending

[0019] Dry blends of the components were prepared using the ingredients listed in Table I below by blending the solid ingredients until a homogeneous mixture was obtained, then heating the mixture to 85°C. The liquid ingredient mixture is then slowly added to the stirred mixture. After all the liquid had been added to the mixture, the mixture was heated to 110°C and stirred for 10 minutes. Allow the stirred blend to cool to 70 °C and add enough SiO 2 to obtain a free-flowing dry blend. The dry blend was then cooled to ambient temperature and collected.

[0034] Fabrication of Metaflumizone Components on Fabric Substrates

[0035] A dry blend prepared as described in Example 1A was used to prepare a metaflumizone-containing assembly comprising 54 parts by weight metaflumizone and 18 parts by weight of several plasticizers per 100 parts PVC. These dry blends were granulated and extruded onto a fabric substrate and punched and die-cut to the desired shape, resulting in insecticidal components weighing approximately 8 grams.

[0037] Preparation of metaflumizone coating composition

[0038] 180 g acetyl tributyl citrate was added to a stirred mixture of 300 g vinyl resin with an intrinsic viscosity of 1.20 and an average particle size of 0.95 microns, optionally 6 g Ca / Zn stearate and 9 g epoxidized soybean oil. To this stirred mixture was added 100 g of metaflumizone (90% purity). The resulting mixture was stirred until homogeneous and then degassed overnight at room temperature and 686 mm / Hg.

Abstract

The present invention provides novel insecticidal animal ear tags, neck collars or pendants, and a method for controlling insects in a homeothermic animal.

Description

technical field [0001] The present invention relates to a device and method for controlling insects. Background technique [0002] Many of the recently developed techniques for controlling insects include slow release insecticide techniques. U.S. Patent No. 3,318,679; U.S. Patent No. 3,944,662; U.S. Patent No. 3,756,200; U.S. Patent No. 3,942,480; Circles, ribbons and labels. The latter patent describes an insect control device comprising an insecticidally active isomer of alpha-cyano-3-phenoxy-benzyl-alpha-isopropyl-4-chlorophenyl acetate. US Patent No. 5,104,569 describes coated devices that enable the incorporation of insecticides that are not suitable for incorporation into devices prepared by extrusion and injection molding. [0003] The proliferation of devices such as insecticidal animal ear tags, collars and pendants over the past few years has led to considerable effort being devoted to developing improved devices to overcome the risks of exposure as the use of s...
