Toxicological data

Butoxycarboxim is a synthetic insecticide and acaricide from the active ingredient group of oxime carbamates . It was introduced by Wacker Chemie in 1970 .

Extraction and presentation

Butoxycarboxim can by the oxidation of Butocarboxim with peracetic acid are obtained. Alternatively, it can also be prepared from 3-methylsulfon-2-butanone and hydroxylamine with subsequent reaction with methyl isocyanate .

Butoxycarboxime is also a metabolite in the breakdown of butocarboxime in mammals.

Mode of action

Butoxycarboxim is an insecticide that acts as a contact poison and food poison. The active ingredient is distributed throughout the plant after ingestion via the roots.

Its mode of action is comparable to other carbamate insecticides. By inhibiting the enzyme acetylcholine esterase in the synapses of the nervous system , the transmission of stimuli to the nerves is blocked. The nerves remain permanently in an excited state. The resulting paralysis can lead to respiratory arrest and ultimately to the death of the affected organism.

Areas of application

Butoxycarboxim is mainly used against spider mites and aphids in potted plants . Typical forms of application are cardboard sticks that have been provided with the active ingredient and that are stuck into the ground.

toxicology

Butoxycarboxime is classified as a Class Ib toxin (very dangerous) by the World Health Organization . Symptoms of poisoning with Butoxycarboxim can cause muscle weakness, sweating, dizziness, tiredness, nausea, diarrhea and headache.

Butoxycarboxim is not toxic to fish and bees .

Analytics

The reliable detection and quantification of butoxycarboxime is possible using liquid chromatographic methods. After the chromatographic separation, a mass spectrometer can be used to identify the substance .

Admission

Butoxycarboxim is not approved in the European Union . The maximum residue level for all foods is 0.01 mg / kg.

Trade names

  • Plant Pin (Wacker)
  • Bellasol ( BASF )
