Patent number: 5705648Abstract: Mepiquat chloride is formed from the reaction between N-methylpiperidine and chloromethane in an anhydrous liquid solvent selected from the group consisting of acetone, methyl ethyl ketone, toluene, tetrahydrofuran, isopropanol, acetonitrile, N,N-dimethylformamide and methylene chloride in the absence of sodium hydroxide. Mepiquat chloride precipitates as a solid of high purity and is recovered under a substantially moisture-free atmosphere.The solid mepiquat chloride can be sealed into a water soluble pouch or into a water soluble encapsulated solid form (e.g., granule, pellet, or briquette) for convenient handling. The pouch contains powdered mepiquat chloride or the encapsulated solid is merely introduced directly into a spray tank or reservoir for application with low human exposure and no containers in contact with the mepiquat chloride that require disposal.Mepiquat chloride is used as a component of a system for growing a number of commodity plants including cotton.Type: GrantFiled: October 17, 1994Date of Patent: January 6, 1998Assignee: Micro Flo Co.Inventors: Richard U. Clark, James S. Lovell, James C. Thigpen, David William Bristol, John Raymond Tyndall, Albert Roger Frisbee

Patent number: 5705193Abstract: A process for the preparation of granules containing at least one active principle with a melting point above 70.degree. C. selected from the group consisting of herbicides, fungicides and insecticides comprising dissolving the active principle in an aromatic solvent or pyrrolidone, absorbing the resulting solution on a support, optionally adding water thereto and drying the resulting product to form the granules and the granules produced thereby which have a superior biological activity than a granule dispersible in water with good stability.Type: GrantFiled: June 20, 1996Date of Patent: January 6, 1998Assignee: Roussel UclafInventors: Michel Bourgogne, Colette Meinard

Patent number: 5703010Abstract: The invention relates to water-emulsifiable granules of crop protection agents composed of the pesticidal active substance in liquid or dissolved form and an at least partially water-soluble shell-forming structural material, to the use of these granules as novel, advantageous formulations of crop protection agents, and to processes for their preparation. It furthermore relates to the general use of polyvinyl alcohols as shell-forming structural materials in the preparation of water-emulsifiable granules which contain organic compounds dissolved in a high-boiling solvent or solvent mixture.Type: GrantFiled: September 12, 1996Date of Patent: December 30, 1997Assignee: Hoechst AktiengesellschaftInventors: Rudolf Heinrich, Thomas Maier, Jean Kocur, Rainer Schlicht

Patent number: 5700475Abstract: Flowable composites are disclosed which comprise a) microcapsules comprising one or more non-aqueous pesticidally active compositions enclosed in an inert water-soluble wall material; b) a non-aqueous liquid in an amount sufficient to maintain the composite flowable; the non-aqueous pesticidally active composition and the non-aqueous liquid being reactive with each other and the inert water-soluble wall material being insoluble in and impermeable to the non-aqueous liquid and the pesticidally active composition. Also disclosed are composites in which the pesticidally active compositions are internally-reactive in the presence of a non-aqueous liquid or solvent. Processes for production of the composites and their utilization as pesticides are also disclosed.Type: GrantFiled: December 29, 1995Date of Patent: December 23, 1997Assignee: Monsanto CompanyInventors: Brent D. Massman, Maria L. Miller

Patent number: 5698208Abstract: Methods and compositions, which rely upon borax toxicants, to control Tephritidae fruit fly populations below economic thresholds are disclosed. More particularly, methods and compositions which utilize borax toxicants are disclosed which cause the Tephritidae fruit flies to die prematurely or which interfere with the female Tephritidae fruit flies to produce eggs for a period of about seven days. A preferred borax toxicant is borax wherein an effective amount in the compositions to accomplish the above is between at least about 0.01M and about 0.12M or more. A lethal amount of borax that should be consumed by the fruit flies in about a 24 hour period is believed to be between at least about 5 mM and about 10 mM or more, whereas the amount of borax that should be consumed by the female fruit flies within about a 24 hour period to prevent the female fruit flies from producing eggs for about seven days or longer is believed to be at least about 2.5 mM and 5 mM or more.Type: GrantFiled: September 19, 1995Date of Patent: December 16, 1997Assignee: University of FloridaInventors: Herbert N. Nigg, Samuel E. Simpson

Patent number: 5695814Abstract: A biocidal powder for sustained release of chlorine dioxide includes particles containing chlorite anions, and a hydrophobic core having the particles on a surface thereof, the hydrophobic core containing an acid releasing agent. The particles and the hydrophobic core are substantially free of water, and the particles are capable of releasing chlorine dioxide upon hydrolysis of the acid releasing agent.Type: GrantFiled: July 17, 1996Date of Patent: December 9, 1997Assignee: Southwest Research InstituteInventors: Stephen T. Wellinghoff, Joel J. Kampa, Darren E. Barlow
