ABSTRACT:
There are described novel homoserine derivatives of the formula (I) ##STR1## which possess valuable microbicidal properties. In the formula: Ar is substituted phenyl or naphthyl; R.sub.1 is C.sub.2 -C.sub.6 alkyl optionally interrupted by oxygen or sulfur, 2-furyl, 2-tetrahydrofuryl, 1H-1,2,4-triazolylmethyl, 1-imidazolylmethyl, 1-pyrazolylmethyl, C.sub.2 -C.sub.4 alkenyl or cyclopropyl, each of which is optionally substituted by halogen; R.sub.2 is hydrogen or methyl; R.sub.3 is hydrogen or C.sub.1 -C.sub.4 alkyl; and B is halogen or an ester, thioester, sulfonic acid ester or sulfonic acid amide group. Additionally, where B is halogen, R.sub.1 may be halomethyl. The novel derivatives can be used for combating microorganisms harmful to plants, particularly for combating phytopathogenic fungi, and they have for practical requirements a very favorable curative and protective action for protecting cultivating plants, without the plants being impaired as a result of undesirable secondary effects. A notable feature is their stability to heat and to solar irradiation. They can be used in practice on their own or in the form of pesticidal compositions.
