Phosmet

Type: Insecticide

Mode of Action: Inhibiting the enzyme acetylcholinesterase

Common Product Names: Imidan

What is it?

Phosmet is a broad-spectrum insecticide that has been in use for many years. It is particularly effective against a variety of pests, including those that attack fruit trees, vegetables, and other crops. Phosmet is valued for its ability to control pests that have developed resistance to other types of insecticides. It is available in several formulations, including wettable powders, emulsifiable concentrates, and dust.

How does it work?

Phosmet works by interfering with the nervous system of insects. When insects come into contact with Phosmet, it is absorbed through their cuticle or ingested. Once inside, it inhibits the acetylcholinesterase enzyme, causing an accumulation of acetylcholine at nerve synapses. This leads to continuous nerve impulses, muscle spasms, paralysis, and eventually death of the insect.

Benefits

  • Residual Effect: Provides long-lasting control, reducing the frequency of applications.
  • Resistance Management: Useful in managing pests that have developed resistance to other insecticides.
  • Quick Results: Visible effects on pest populations can be seen within a few days of application.
