Abstract: The present invention is directed to a pesticidal composition of a water-soluble pesticide and processes for its manufacture. More specifically, the invention relates to a soluble granule (SG) pesticidal formulation comprising a water-soluble pesticide and a water-soluble filler. The present invention provides a pesticidal formulation with efficacy equal to the corresponding liquid formulation, yet with improved handler safety, such as lower eye irritation.

Abstract: An apparatus for producing an extrudate (e.g., water-dispersable extruded rod-shaped granules) from an extrudable powder-based material (e.g., a finely-divided water-insoluble powder) includes a hopper for the extrudable material having at least one extrusion aperture at its lower end, a rotatable extruder tool at or near the lower end of a first drive shaft for forcing the extrudable material through the aperture(s) and a rotatable feeder at or near a lower end of a second drive shaft for feeding the extrudable material to the extruder tool. The first drive shaft is rotatably mounted within the second drive shaft by axially displaced bearings, the second drive shaft being mounted within a fixed bearing housing by further axially displaced bearings. Drive motors are connected by respective drive trains to the upper ends of the first and second drive shafts, respectively.

Abstract: Agriculturally active materials, such as pesticides, herbicides and the like and a process for microencapsulating said materials. The present invention includes trifluralin having a polymorphic form characterized by a yellow color and a melting point of approximately 41.degree.-43.degree. C. The present invention also includes a method of using the yellow polymorphic form of trifluralin as a herbicide. In addition, the present invention includes a method of microencapsulating low-melting agriculturally active materials, such as trifluralin. The microencapsulation process comprises the steps of heating a low-melting, water-immiscible, agriculturally active material to a molten state. The molten active material is then combined with an aqueous solution of a water-soluble, film-forming polymer at a temperature sufficient to maintain the active material in its molten state.

Abstract: A method of protecting mating screw threads at least under tightening torques is described in which a dry lubricant such as molybdenum disulphide is applied to one screw thread, and a liquid lubricant is applied to the other screw thread. The screw threads are then tightened to the required torque value. When completely mated the leakage path will not be masked as a result of volatilization of any of the components of either lubricant.

Abstract: The present invention relates to a process for the preparation of water dispersible granular herbicidal compositions with increased thermal stability, which contain low melting substituted dinitroaniline compounds.
