Agents for preserving technical materials against insects

The use of the compounds of the formula (I)

Novel benzophenonehydrazone derivatives represented by the formula (I): ##STR1## wherein, R.sup.1 is halogen; R.sup.2 is hydrogen or C.sub.1-4 alkyl; R.sup.3 is cyano, optically substituted C.sub.1-4 alkyl, C.sub.2-4 alkenyl, C.sub.3-4 alkynyl, C.sub.1-4 alkyl-carbonyl or C.sub.1-4 alkoxy-thiocarbonyl; R.sup.4 is hydrogen, phenyl, optionally substituted C.sub.1-6 alkyl, optionally substituted C.sub.2-8 alkenyl, --CO--R.sup.8, --CO--O--R.sup.9 or ##STR2## R.sup.5 is hydrogen, formyl, phenyl, optionally substituted C.sub.1-8 alkyl, optionally substituted C.sub.2-8 alkenyl, optionally substituted C.sub.3-8 alkynyl, optionally substituted C.sub.1-8 alkyl-arbonyl, optionally substituted C.sub.1-6 alkyl-oxalyl, optionally substituted C.sub.1-8 alkoxy-carbonyl, optionally substituted C.sub.1-8 alkoxy-oxalyl, optionally substituted C.sub.3-8 cycloalkyl-carbonyl, optionally substituted C.sub.2-8 alkenyl-carbonyl or optionally substituted benzoyl; R.sup.6 is hydrogen or halogen; R.sup.7 is hydrogen, halogen or C.sub.1-2 alkyl, C.sub.1-4 alkyl-carbonyl or C.sub.1-4 alkoxy-thiocarbonyl; n is 0, 1 or 2, provided that n is 0 when R.sup.3 is cyano, C.sub.1-4 alkyl-carbonyl or C.sub.1-4 alkoxy-thiocarbonyl, is a single bond of Anti form or of Syn form. The benzophenonehydrazone derivatives of the formula (I) have excellent insecticidal activities.

Benzophenone hydrazone derivatives as insecticides

Novel pesticidal sulfamide derivatives of the formula ##STR1## in which X is halogen or C.sub.1 -C.sub.4 -halogenoalkyl, R.sup.1 is C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -halogenoalkyl, R.sup.2 is hydrogen or C.sub.1 -C.sub.4 -alkyl, and R.sup.3 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxycarbonyl or C.sub.1 -C.sub.4 -alkoxycarbonylmethyl.
