Uses and applications

What the substance is used for, by industry and function

Selective soil incorporated herbicide. (Former).

Vernolate is selective herbicide which... will control annual grass species such as crabgrass... foxtails... goosegrass... and barnyard grass... It will control nutsedges... and seedling johnsongrass... It is... useful against certain broadleaf weed species such as annual morning glory... purslane... pigweed...

Controls... wild cane. Broadleaf weeds such as... lambsquarters, sicklepod,... carpetweed... will be controlled if application is made when conditions are favorable for germination.

Control of germinating broad-leaved and grass weeds in groundnuts, soya beans, maize, tobacco and sweet potatoes. ...Soil incorporation is necessary, either pre-planting or pre-emergence.

Use classes: Herbicides.

Roles

  • eukaryotic metabolite
  • metabolite
  • plant metabolite

Functional uses

  • Biocide

How it is made

Vernolate is produced by reaction of N-dipropylcarbamoyl chloride with propylmercaptan.

Sodium dispersion method: ... anhydrous alkoxide-free sodium alkylmercaptide is refluxed with ... dialkylcarbamoyl chloride in xylene. After removal of most of solvent, remaining product is then subjected to fractional distillation.
