Abstract
The present invention relates to a hydrazone compound of the formula (I) or its salt, a process for its preparation, an intermediate of the formula (II-5), a pesticidal composition containing said hydrazone compound or its salt as the active ingredient, and a pesticidal method of applying an effective amount thereof: ##STR1##
Claims4
A hydrazone compound of the formula (I) or its salt ##STR45## wherein each of R.sup.1, R.sup.2 and R.sup.4, which are independent of one another, is a hydrogen atom, a halogen atom, an alkyl group which may be substituted by a halogen atom, or an alkoxy group which may be substituted by a halogen atom, R.sup.3 is a halogen atom, an alkyl group which may be substituted by a halogen atom, or an alkoxy group which may be substituted by a halogen atom, R.sup.5 is a hydrogen atom, or an alkyl group, R.sup.6 is X.sup.7 CO-- (wherein X.sup.7 is a hydrogen atom, or an alkyl group), or X.sup.8 OCO-- (wherein X.sup.8 is an alkyl group), or R.sup.5 and R.sup.6 together form .dbd.CR.sup.7 R.sup.8 (wherein R.sup.7 is a hydrogen atom, or an alkyl group, and R.sup.8 is an amino group which may be substituted by an alkyl group, or an alkoxy group),
- provided that the following cases (1) to (3) are excluded:
- (1) a case where R.sup.2, R.sup.4 and R.sup.5 are hydrogen atoms, R.sup.6 is an ethoxycarbonyl group, and at least one of R.sup.1 and R.sup.3 is p-methoxy group,
- (2) a case where R.sup.1, R.sup.2, R.sup.4 and R.sup.5 are hydrogen atoms, R.sup.3 is a p-tert-butyl group, and R.sup.6 is an ethoxycarbonyl group,
- (3) a case where R.sup.1, R.sup.2 and R.sup.4 are hydrogen atoms, R.sup.3 is a p-fluorine atom, R.sup.5 is an isopropyl group, and R.sup.6 is an acetyl group.
