摘要:
Novel phosphoric acid esters of the formula ##STR1## where R.sup.1 is alkoxy of a maximum of 4 carbon atoms or phenyl, R.sup.2 is alkyl of a maximum of 3 carbon atoms, alkoxy or alkylthio of a maximum of 4 carbon atoms, or alkylamino or dialkylamino, each alkyl being of a maximum of 4 carbon atoms, R.sup.3 is methyl, ethyl, hydrogen or chlorine, R.sup.4 and R.sup.5 are phenyl or alkyl of a maximum of 4 carbon atoms, or are, together with the nitrogen atom, a 5- to 7-membered heterocycle, and X is oxygen or sulfur, with the proviso that R.sup.1 is not phenyl when R.sup.2 is alkyl. The compounds are suitable for combating pests.

摘要:
New phosphoric acid derivatives and pesticides containing these phosphoric acid derivatives as active ingredients. The new active ingredients are obtained by reaction of .alpha.-formylalkylphosphonic acid esters with phosphoric (phosphonic) acid ester halides or by reaction of .alpha.-formyl-.alpha.-haloalkylphosphonic acid esters with phosphites.The compounds are suitable for combatting pests from the classes of insects, Arachnida and nematodes in the crop protection, hygiene, stores protection and veterinary sectors.
摘要:
New and valuable dithiophosphoric esters which have a strong insecticidal and acaricidal action, and a process for controlling pests with these compounds.
摘要:
New and valuable pesticide on the basis of an active ingredient from the group of organophosphorus compounds or chlorinated hydrocarbons, and additionally containing a thiol carbamate.
