| 摘要 |
The invention refers to compositions suitable for the promotion of plant production and for the elimination of unfavourable environmental influences, said compositions comprising a hydroximic acid derivative of formula (I), wherein R1 represents a hydrogen atom or a C1-5alkyl group, R2 stands for a hydrogen atom, a C1-5alkyl group, a C3-8 cycloalkyl group or a phenyl group optionally substituted by a hydroxy or a phenyl group, or R1 and R2 together with the nitrogen atom they are attached to form a 5 to 8 membered ring optionally containing one or more further nitrogen, oxygen or sulfur atom(s) and said ring can be condensed with another alicyclic or heterocyclic ring, preferably a benzene, naphthalene, quinoline, isoquinoline, pyridine or pyrazoline ring, furthermore, if desired and chemically possible, the nitrogen and/or sulfur heteroatom(s) are present in the form of an oxide or dioxide, R3 means a hydrogen atom, a phenyl group, a naphthyl group or a pyridyl group wherein said groups can be substituted by one or more halo atom(s) or C14alkoxy group(s), Y is a hydrogen atom, a hydroxy group, a C1-24alkoxy group optionally substituted by an amino group, a C2-24polyalkenyloxy group containing 1 to 6 double bond(s), a C1-25alkanoyl group, a C3-9alkenoyl group or a group of the formula R7 -COO- wherein R7 represents a C2-30polyalkenyl group containing 1 to 6 double bond(s), X stands for a halo atom, an amino group, a C1-4alkoxy group, or X forms with B an oxygen atom, or X and Y together with the carbon atoms they are attached to and the -NR-O-CH2- group being between said carbon atoms form a ring of formula (a), wherein Z represents an oxygen atom or a nitrogen atom, R stands for a hydrogen atom or, R forms with B a chemical bond, A is a C1-4alkylene group or a chemical bond or a group of formula (b), wherein R4 represents a hydrogen atom, a C15alkyl group, a C3-8cycloalkyl group or a phenyl group optionally substituted by a halo atom, a C1-4alkoxy group or a C1-5alkyl group, R5 stands for a hydrogen atom, a C1-4alkyl group or a phenyl group, m has a value of 0, 1 or 2, n has a value of 0, 1 or 2, or a physiologically acceptable acid addition salt thereof as the active ingredient.
