New oxyalkanimidoylphenyl-substituted N-(heterocyclyl)-alkanoamide derivatives, are bactericides, fungicides, insecticides, acaricides and nematocides, useful e.g. in plant or material protection or as antimycotic agents

摘要

Oxyalkanimidoylphenyl-substituted N-(isothiazolyl, thiadiazolyl or pyridyl)-alkanoamide derivatives (I) are new. Oxyalkanimidoylphenyl-substituted N-(isothiazolyl, thiadiazolyl or pyridyl)-alkanoamide derivatives (I) are new. [Image] A : alkanediyl; R11,2-thiazolyl, 1,2,4-thiadiazolyl or pyridyl (all optionally substituted); R2H, alkyl or optionally substituted phenyl; R3H, alkyl, alkoxyalkyl, alkenyl or alkylcarbonyl; or (all optionally substituted) aryl, aralkyl, arylcarbonyl, heterocyclyl, heterocyclylalkyl or heterocyclylcarbonyl; R4H, halo, alkyl, alkoxy, CN or NO2. An independent claim is included for the preparation of (I). - ACTIVITY : Antibacterial; fungicide; insecticide; acaricide; nematocide. 2-(3-((1-N-Tert. butoxyethanimidoyl)-phenyl)-N-(3-ethyl-1,2,4-thiadia zol-5-yl)-acetamide (Ia) at 100 g/ha gave more than 90% protection of apple trees against Podosphaera leuchotricha. - MECHANISM OF ACTION : None given.
