摘要:
There are described novel compounds of the formula I defined herein: ##STR1## which have valuable microbicidal properties. The novel compounds can be used for combating microorganisms harmful to plants, particularly for combating phytopathogenic fungi. The compounds of the formula I thus have a very favorable curative and preventive action for practical requirements for the protection of cultivated plants, without the plants being impaired as a result of undesirable secondary effects. The compounds can be used in practice on their own or in the form of pesticidal compositions.
摘要:
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.

N-Acylated N-phenyl-aminotetrahydro-2-furanones of tthe formula ##STR1## wherein R represents C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or halogen,R.sub.1 represents C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.4 -alkoxy or halogen,R.sub.2 represents hydrogen, C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.4 -alkoxy or halogen,R.sub.3 represents hydrogen or methyl, with the total number of C atoms of the substituents R, R.sub.1, R.sub.2 and R.sub.3 in the phenyl ring not exceeding the number 8,R.sub.4 represents hydrogen or methyl, whileR.sub.5 represents one of the following groups: an alkylthioalkyl or alkoxyalkyl group having 2 to 5 carbon atoms or an alkoxyalkoxymethyl group having a maximum of 6 carbon atoms, a 2-furanyl or 2-tetrahydrofuranyl group optionally substituted by halogen, a 1,2,4-triazolymethyl group, a 1,2-pyrazolylmethyl group, or a group -CH.sub.2 -OR.sub.6 in which R.sub.6 represents a 5- or 6-membered heterocycle having oxygen as the hetero atom are valuable fungicidal active substances. They can be used as fungicidal compositions, particularly for combating phytopathogenic fungi, e.g. against downy mildew on potatoes, tomatoes, grape vines and sugar beet and other plants. The novel compounds have a systemic action.
