Uses and applications

What the substance is used for, by industry and function

Acaricide for fruits, vegetables, row crops.

Acaricide / miticide.

Control of phytophagous mites (particularly motile stages) on a variety of crops, including vines, fruit trees (e.g. top fruit, stone fruit, citrus fruit), hops, nuts, tomatoes, vegetables, ornamentals, cotton, maize, peanuts, and sorghum. Used at rates from 0.75-1.8 kg/ha on row crops and foliar sprays of 0.85-3.0 kg/ha on perennial fruit and nut crops.

Roles

  • acaricide
  • pesticide
  • sulfite ester acaricide

Functional uses

  • Biocide

How it is made

Propargite is produced by the reaction of 4-tert-butylphenol with 1,2-epoxycyclohexane, followed by treatment with thionyl chloride to give the chlorosulfinate, then with 2-propynol (propargyl alcohol) in the presence of a base.

Reaction of p-tert-butylphenol & cyclohexene oxide to yield a glycol ether, & conversion to a chlorosulfinate by thionyl chloride. Chlorosulfinate & propargyl alc react in presence of hydrogen chloride acceptor to give omite.
