3, 5-Dialkyl-4-hydroxybenzylidenemalononitrile; A New Group of Fungicidal and Acaricidal Agents

Abstract

Several 3, 5-dialkyl-4-hydroxybenzylidenemalononitriles and related compounds were tested for their fungicidal and acaricidal activities. The influence of structural variation on biological activity was studied by preparing and using a total of 22 compounds of benzylidenemalononitrile analogues. Amongst the compounds tested 3, 5-di-tert-butyl and amyl-4-hydroxybenzylidenemalononitrile were most effective against fungus, Piricularia oryzae Car. and mite, Tetranychus telarius L.
