Abstract

Abstract Hydroxamic acid chelates of the type ML 2, ML 2', and ML 2' where M = Cu(II), Ni(II) or Co(II) and L = N,2'-diphenylacetohydroxamic acid ( N,2'-DPAHA), L' = 2,2'-diphenylacetohydroxamic acid (2,2'-DPAHA), and L'' = 2-phenylacetohydroxamic acid (2-PAHA) have been isolated and characterized on the basis of elemental analysis and infrared and magnetic data. These metal chelates were screened for their fungicidal activity. The testing against fungi has been carried out by slide germination technique against Alternaria alternata and by inhibition zone technique against Fusarium oxysporum and Aspergillus flavus. The fungicidal activity of chelates and their parent ligand has been compared with the commercial fungicide, Dithane M-45, screened under similar conditions.
