An aqueous suspension or slurry (suspension concentrate) contains a synergistic amount of thidiazuron, diuron and surfactants. The aqueous suspension contains surfactants in amounts to obtain a stable suspension or slurry without the use of organic solvents.

Defoliant composition and method

Objectionable odors from agrichemicals can be masked by adding one or more terpene or their oxygenated derivatives to the formulation before, during, or after application. A particularly preferred formulation is a granulated insecticide that includes an insecticidal amount of a phosphoroamido(di)thioate in solid form, a polymeric binder, a small amount of an anticking aid, and a masking agent containing an essential oil that is either mixed throughout the granule or sprayed onto its surface. The essential oil masks objectionable odors from the active ingredient without adversely affecting the storage stability or efficacy of the active ingredient.

Masking agent for agrichemicals

Granulated forms of various active ingredients can be prepared with a small amount of a dissolvable polymer and a solvent for that polymer. The solvent dissolves at least a portion of the polymer. This dissolved polymer acts as a particle lubricant for the extrusion process and, when the solvent is removed, as a binder for the final extrudate. A poly(alkylene oxide) is preferred and, in the presence of a small amount of solvent, dissolves sufficiently to provide lubricity to the extrusion mixture that the solids can be extruded with little friction and associated local temperature rise thru the extrusion die.
