Abstract: Briefly stated a tag includes a dielectric substrate having first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap which establishes an electrical open circuit. An electrically conductive composition including electro-conductive particles is provided for bridging the gap in the conductive pattern to temporarily establish an electrical closed circuit which resonates when exposed to electromagnetic energy at a frequency within a predetermined frequency range.

Abstract: A resonant tag circuit useful as an electronic security device includes a layered planar structure having a dielectric substrate, a resonant circuit carried on both sides of the dielectric substrate and a semiconductive material having an ionizable salt dissolved therein. The semiconductor material provides a sermiconductive bridge across an activation or deactivation point in the circuit and connects the conductive circuit on both sides of the activation or deactivation point. The resonant tag circuit of this invention is stabilized against premature operation of the activation or deactivation point from electrostatic discharge.

Abstract: Water-soluble or water-dispersible granular compositions prepared by coating a water-soluble sulfonylurea herbicide or a water-soluble or water-dispersible form of a sulfonylurea herbicide on a granular substrate using a water-soluble polyethylene glycol binder, and a method for controlling undesired vegetation.

Abstract: This invention relates to slow release granular compositions comprising one or more active herbicides and a process for their preparation.

Abstract: Compositions of azole fungicides exhibiting reduced eye irritation are prepared by replacing a significant portion of the hydrocarbon solvent with a combination of propylene glycol and a long chain fatty alcohol.

Abstract: The use of selected metribuzin analogs to control crystallization of metribuzin in mixtures of metribuzin and aromatic hydrocarbon-based grass killing herbicides is disclosed.

Abstract: N-Methylol derivatives of herbicidal 4-amino-1,2,4-triazine-5-ones can be prepared by reacting formaldehyde with a 4-amino-1,2,4-triazine-5-one slurried in water under basic conditions. The N-methylol derivatives can be surface-modified by slurrying particles of the derivatives in water and treating with a strong acid or strong base, producing a product that releases the original herbicidal 4-amino-1,2,4-triazine-5-one in a controlled manner.

Abstract: Asymmetrical triazine salts form stable formulations which are useful as agricultural chemicals.

Abstract: Liquid insecticidal compositions having a high concentration of active ingredients are formed from a carbamate insecticide, a reaction product of the insecticide and formaldehyde or paraformaldehyde, and 1-35% by weight, based on the weight of the composition, of water.

Abstract: Controlled release granules of methyl 2-(dimethylamino)-N-[[(methylamino)carbonyl]oxy]-2-oxo-ethanimidothioate, oxamyl, are effective soil insecticides and nematicides, and are especially useful for the prolonged control of root knot nematodes.

Abstract: The instant invention relates to a process for preparing novel insecticide-polymer particles. The process consists essentially of dissolving the insecticide, methomyl, and a polymer in a solvent in which both are soluble. The solution is then comingled with a non-solvent for both the polymer and the methomyl under high shear conditions. A particulate product is formed consisting of irregularly shaped particles having methomyl embedded in a polymer matrix. The irregularly shaped particles may be dispersed, e.g. in water, and sprayed readily into an area of insect infestation.

Abstract: Slow release insecticide microcapsules having a core of methomyl surrounded by a cover of all-aromatic, uncrosslinked polyurea.
