Abstract
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.
Claims28
An agrichemically effective solid formulation in powder or granular form and comprising:
- a. sulfur-containing active ingredient solids in an agrichemically effective amount, wherein said active ingredient solids emit volatile sulfur-based odors that are objectionable to human perception,
- b. 0-90 wt % of an aromatic solvent for said active ingredient, and
- c. about 0.01 to 2 wt % of a masking agent comprising a terpene or oxygenated derivative thereof in an amount sufficient to reduce human perception of objectionable odors from said sulfur-containing active ingredient solids.
An insecticidally effective formulation in powder or granular form and comprising:
- a. about 1 to 99.5 wt % of phosphoroamido(di)thioate solids in an insecticidally effective amount, wherein said solids emit odors that are objectionable to human perception, and
- b. about 0.01 to 2 wt % of a masking agent comprising a terpene or oxygenated derivative thereof in an amount sufficient to reduce human perception of objectionable odors from said formulation.
An agrichemically effective formulation comprising:
- a. about 75 to 99 wt % acephate,
- b. a polymeric binder for said active ingredient, wherein said binder comprises a polyalkylene oxide,
- c. 0-90 wt % of an aromatic solvent for said active ingredient,
- d. about 0.05 to 1 wt % of a masking agent comprising a lemon essential oil to reduce human perception of objectionable odors from said acephate.
