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:
Oximinophosphoric acid derivatives of the formula I ##STR1## where R.sup.1 is unbranched or branched alkyl of up to 4 carbon atoms,R.sup.2 is unbranched or branched alkoxy or alkylthio of up to 4 carbon atoms, unbranched or branched alkyl of up to 3 carbon atoms, phenyl, amino or alkylamino or dialkylamino, where each alkyl is unbranched or branched and of up to 4 carbon atoms,R.sup.3 is hydrogen or methyl,X is oxygen or sulfur andn is 1 or 2,and their use in pest control.
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:
Oximinophosphoric acid derivatives of the formula ##STR1## where R.sup.1, R.sup.2 and R.sup.3 have the meanings given in the description, processes for their preparation, and their use for controlling pests.
摘要:
The compound 2-(methylthiomethylthio)-phenyl-N-methylcarbamate of the formula ##STR1## and a process for controlling pests with this compound. The compound is particularly effective on plant-damaging Homoptera.
摘要:
Trifluoromethoxyphenyl-(di)-thiophosphoric acid esters of the formula ##STR1## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and X have the meanings given in the description, and their use in pest control.
摘要:
