Abstract
Pesticidal thionophosphonic acid(amide) esters of the formula ##STR1## in which R.sup.1 stands for optionally substituted alkyl or alkenyl, R.sup.2 stands for optionally substituted alkoxy, alkenyloxy or alkinyloxy, or for the group ##STR2## in which R.sup.3 and R.sup.4 are identical or different and independently of one another stand for hydrogen or for optionally substituted alkyl, cycloalkyl, alkenyl or alkinyl, or together with the nitrogen atom form a 5- to 7-membered, saturated or unsaturated ring and X stands for halogen. Intermediates of the formuula ##STR3## are also new.
