METHOD FOR PREPARING MOLUSCYCID COMPOSITIONS CONTAINING ALUMINUM- (III) AND / OR IRON-CHELATES (III)

摘要

The use as a molluscicide of a chelate of aluminium (III) with a ligand of formula I or of iron (III) with a ligand of formula II I: [R1COCHCOCR2]- II: [R3NO.N=O]- in which formulae: R1 and R2, which may be identical or different, represent: methyl, ethyl, propyl, methoxyethyl, ethoxyethyl, dimethoxy methyl or diethoxymethyl and R3 represents: C1-C6 alkyl, provided that when the alkyl group contains more than four carbon atoms the group is a branched chain alkyl group.
