ABSTRACT:
New pyridazinonyl-(di)(thio)-phosphoric (phosphonic) acid esters of the formula ##STR1## where X and Y each denote oxygen or sulfur, R.sup.1 denotes linear or branched alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, mono- or dialkylamino of 1 to 4 carbon atoms in each alkyl, phenyl, or benzyl, R.sup.2 denotes linear or branched alkyl of 1 to 4 carbon atoms, phenyl or benzyl, R.sup.3 denotes linear or branched alkyl of 1 to 4 carbon atoms or phenyl, R.sup.4 denotes linear or branched alkyl of 1 to 4 carbon atoms, or R.sup.3 and R.sup.4, together with the oxygen and the carbon atom whose substituents they are, form a 5- or 6 membered saturated ring which may be substituted by alkyl of 1 to 4 carbon atoms, which are effective against pests, especially insects and Arachnida, pesticides containing these pyridazinonyl-(di)(thio)-phosphoric (phosphonic) acid esters as active ingredients, and a process for combating pests with these active ingredients.
The present invention relates to new pyridazinonyl-(di) (thio)-phosphoric (phosphonic) acid esters, a process for their manufacture, and pesticides, especially insecticides and acaricides, containing these compounds as active ingredients.
