Patent number: 8053392Abstract: An auxin acid-catalyzed stable microemulsion pesticide formulation is provided that is clear and stable under a wide range of temperature conditions encountered during distribution, storage, and use of the pesticide formulation. A precursor for the microemulsion includes an auxin ester, a protox inhibitor, and an auxin acid stabilizing agent as active ingredients. Inactive ingredients in the precursor include a microemulsifier, a stabilizing co-emulsifier, a dispersant, and a solvent present in amounts such that when the precursor is added to water of dilution to form a concentrate or a ready-to-use formulation, the clear and stable microemulsion that is spontaneously formed has oily active ingredient-containing nano-sized particles no larger than about 1? dispersed in the water.Type: GrantFiled: January 23, 2007Date of Patent: November 8, 2011Assignee: PBI/Gordon CorporationInventors: Dale Sanson, James A. Armbruster

Publication number: 20080311221Abstract: A chemically and physically stable, transparent, hybrid pesticide concentrate is provided for preparation of a water-based microemulsion formulation. The pesticides preferably comprise an oil-soluble pesticide component, and a pesticide component having a Lewis acid pesticide portion and a pesticide complex portion. An inactive biphasic coupling agent for the pesticide ingredients includes a solvent capable of solvating the oil-soluble pesticide component, and two organic cosolvents capable of solvating the Lewis acid pesticide portion and the pesticide complex portion pesticide ingredients, respectively. A selected emulsifier is incorporated in the concentrate. A sufficient quantity of a complexing agent is provided to maintain the electrical potential of the final concentrate at a value of about ?150 mV to about +150 mV.Type: ApplicationFiled: June 14, 2007Publication date: December 18, 2008Applicant: PBI/Gordon CorporationInventors: Dale Sanson, James A.

Publication number: 20080090780Abstract: A storage stable, efficacious pesticide formulation is provided that is dilutable by the user and contains azadirachtin (AZA) and a pyrethrin or pyrethroid (PYR), and optionally an aprotic solvent and non-ionic, substantially water-free emulsifier. A sufficient amount of the PYR is provided to complex with the AZA A on opposite sides of the molecular structure thereof, thereby preventing rearrangement of the AZA A molecule in the presence of moisture that would result in hydrolysis and decomposition of AZA A. The AZA-PYR combination is sufficiently chemically stable such that less than 10% of the AZA A is decomposed when the formulation is subjected to an accelerated aging test for 30 days at 40° C. in a sealed container. The molar ratio of PYR to AZA A is preferably within the range of 0.5/1-10.5/1, more preferably within the range of 1.5/1-7/1, and most preferably with the range of 3/1-6/1.Type: ApplicationFiled: October 13, 2006Publication date: April 17, 2008Applicant: PBI/GORDON CORPORATIONInventors: Dale R.

Patent number: 6849579Abstract: A selective synergistic postemergent herbicide composition is provided for the control of undesired broadleaf vegetation and grassyweeds comprising the combination of quinclorac and a selective herbicidal protox inhibitor. About 0.05 part to about 0.1 part by weight of the protox inhibitor is provided for each part by weight of quinclorac. Better synergistic results are obtained from the combination of quinclorac, a selective herbicidal protox inhibitor, and a selective herbicidal auxinic agent. About 0.05 part to about 0.1 part by weight of the protox inhibitor is provided for each part by weight of quinclorac, and about 1 part to about 4 parts by weight of the auxinic herbicidal agent for each part by weight of quinclorac. The synergistic composition hereof has been found to provide more rapid and better control of grassy weeds such as crabgrass than presently registered herbicides.Type: GrantFiled: June 25, 2003Date of Patent: February 1, 2005Assignee: PBI Gordon CorporationInventors: James A. Armbruster, Dale R. Sanson

Patent number: 5416067Abstract: A dry, water-soluble, substituted phenoxy and/or benzoic acid herbicide is prepared by grinding and dry blending the herbicide in acid form with anhydrous trisodium phosphate or tripotassium phosphate which functions as a solid solubilization medium. From about 0.6 mole to about 16.9 moles of the medium is provided for each mole of active herbicidal agent in the initially dry blended mixture. Herbicidal agents are selected from the group consisting of 2,4-D, 2,4-DB, MCPP, MCPA, dichlorprop, dicamba, and chloramben.Type: GrantFiled: December 27, 1993Date of Patent: May 16, 1995Assignee: PBI - Gordon CorporationInventors: John L.

Patent number: 5280008Abstract: Dry, water-soluble powder, substituted heterocyclic acid, substituted phenol herbicidal compositions, combinations thereof, or in combination with phenoxy and/or benzoic acid herbicides, are prepared by grinding and dry blending the herbicide in acid form with a dry, particulate solubilization medium selected from the group consisting of diammonium phosphate, dipotassium phosphate, disodium phosphate, trisodium phosphate or tripotassium phosphate. At least about 1 mole of the medium is provided for each mole of active herbicidal agent in the initially dry blended mixture. The dry blended mixture may be packaged in suitable containers such as paper bags, and added directly to a quantity of water to form a solubilized herbicidal formulation containing from about 0.1% to about 2-1/2% of the active herbicide and which is suitable for direct application to vegetation to be controlled.Type: GrantFiled: June 14, 1993Date of Patent: January 18, 1994Assignee: PBI-Gordon CorporationInventors: Roger P.

Patent number: 4971630Abstract: A liquid herbicidal composition is disclosed which retains its penetrating and systemic activity after application to susceptible flora under normal ambient conditions for a period of at least six hours by combining at least two different salts of at least one herbicidally active compound and a polyhydric alcohol having 2 to 6 carbon atoms. The salts are preferably amine, ammonium or alkali metal salts of herbicidally active acid halogenated phenoxy acids. The herbicidal composition upon application to noxious vegetation has the unexpected property of retaining its phytotoxic activity throughout the maximum residence time necessary for effective weed and brush control by virtue of the fact that the composition resists crystallization and displays no tendency to either burn or otherwise damage the external cellular layers of the plant being treated.Type: GrantFiled: July 17, 1986Date of Patent: November 20, 1990Assignee: PBI/Gordon CorporationInventor: Johann S. Skaptason

Patent number: 3937826Abstract: A fly killing composition in granular form characterized by synergistic attractant properties, an unusually long useful life, and substantial resistance to inactivation due to moisture. The composition comprises a combination base of granular, dark colored fly attractant such as fish food containing meat by-product material, in conjunction with a cooked, bright yellow, sugar-based attractant. These materials are coated with and absorb into the interstices thereof fly-toxic quantities of a mixture of 2,2-dichlorovinyl 0,0-dimethyl phosphate and 0,0-dimethyl 0-2,4,5-trichlorophenylphosphorothioate. A dusting powder applied to the insecticide impregnated particles assures that the surfaces thereof present a dull appearance notwithstanding the presence of a substantial amount of sugar in the bait formulation.Type: GrantFiled: May 3, 1974Date of Patent: February 10, 1976Assignee: PBI-Gordon CorporationInventor: Lewis P.
