Abstract

Benzamides of the general formula (I) are described as herbicides.

In this formula (I), X, Z and R are radicals such as alkyl and cycloalkyl. Q is a 5-membered heterocycle.

First claim

The invention claimed is:

1. A benzamide of formula (I) or salt thereof

where the symbols and indices are each defined as follows:
Q is a Q1, Q2, Q3 or Q4 radical,

X is (C 1 -C 6 )-alkyl or (C 3 -C 6 )-cycloalkyl,
Z is (C 3 -C 6 )-cycloalkyl,
R is (C 1 -C 6 )-alkyl, (C 3 -C 6 )-cycloalkyl, (C 3 -C 6 )-cycloalkyl-(C 1 -C 6 )-alkyl, (C 1 -C 6 )-alkyl-O—(C 1 -C 6 )-alkyl,
R X is methyl, ethyl, n-propyl, prop-2-en-1-yl, methoxyethyl, ethoxyethyl or methoxyethoxyethyl,
R Y is methyl, ethyl, n-propyl, chlorine or amino,
R Z is methyl, ethyl, n-propyl or methoxymethyl,
n is 0, 1 or 2.

2. A benzamide or salt as claimed in claim 1 , wherein
Q is a Q1, Q2, Q3 or Q4 radical,

X is methyl, ethyl or cyclopropyl,
Z is cyclopropyl or cyclobutyl,
R is methyl, ethyl, cyclopropyl, cyclopropylmethyl or methoxyethyl,
R X is methyl, ethyl, n-propyl, prop-2-en-1-yl, methoxyethyl, ethoxyethyl or methoxyethoxyethyl,
R Y is methyl, ethyl, n-propyl, chlorine or amino,
R Z is methyl, ethyl, n-propyl or methoxymethyl,
n is 0, 1 or 2.

3. The benzamide or salt according to claim 1 , wherein
Q is

X is methyl,
Z is cyclopropyl,
R is methyl,
R X is methyl, and
n is 0.

4. A herbicidal composition comprising a herbicidally active content of at least one compound of the formula (I) or salt as claimed in claim 1 .

5. The herbicidal composition as claimed in claim 4 in a mixture with one or more formulation auxiliaries.

6. A method of controlling unwanted plants, comprising applying an effective amount of at least one compound of formula (I) or salt as claimed in claim 1 or a herbicidal composition thereof to one or more plants or to a site of unwanted vegetation.

7. The method according to claim 6 , wherein the one or more plants are useful plants.

8. The method as claimed in claim 7 , wherein the useful plants are transgenic useful plants.

9. A product comprising a compound of formula (I) or salt as claimed in claim 1 or a herbicidal composition thereof for controlling one or more unwanted plants.
