AMINOALKANEPHOSPHONIC ACIDS AND DERIVATIVES THEREOF AS FUNGICIDAL AGENTS

摘要

A method for killing or inhibiting the growth of fungi using branched aminoalkanephosphonic acids of the general formula wherein R1 and R2 independent of each other are hydrogen or alkyl groups having 1 to 8 carbon atoms, n is an integer of 0, 1, 2 or 3, R3 is an alkyl group having 1 to 12 carbon atoms, R4 is hydrogen or an alkyl group having 1 to 12 carbon atoms, or base salts, esters or acid addition salts thereof. The compounds can be effectively used as fungicides for several purposes and are particularly suitable for control of fungal diseases in plants. The invention also relates to compositions containing certain of the compounds.
