Uses and applications

What the substance is used for, by industry and function

Control of many insect pests (especially Diptera and Pharaoh's ants, but also Coleoptera, Homoptera and Siphonaptera) in public health, stored commodities (including tobacco), food handling, processing and storage establishments, mushroom houses, on animals, and on plants (including glasshouse plants).

Particular uses include control of mosquito larvae, sciarid flies in mushroom houses, cigarette beetles and tobacco moths in stored tobacco, Pharaoh ants, leaf miners on glasshouse chrysanthemums, stored product pests in food and tobacco processing plants and warehouses.

An insecticidal preparation said to act in the manner of a juvenile hormone, which arrests development of insects in the larval stage.

Use classes: Insecticides.

Roles

  • growth regulator
  • insect growth regulator
  • insecticide
  • juvenile hormone mimic
  • pesticide

Functional uses

  • Biocide

How it is made

To a mixture of 10 g of 7-methoxy-3,7-dimethyloctan-1-al, 17 g of diethyl 3-ethoxycarbonyl-2-methylprop-2-enyl phosphonate (77% trans), and 150 ml of dimethylformamide, under nitrogen, 0 °C, with stirring, is added sodium isopropanolate (prepared from 1.5 g of sodium in 150 ml of isopropanol). After addition is complete, the reaction is stirred for 18 hours at room temperature and then worked up by extraction with hexane to yield isopropyl-11-methoxy-3,7,11-trimethyldodeca-2,4-dienoate (mostly trans-2, trans-4), which can be chromatographed and distilled for further purification.
