摘要:
Phytotoxic side effects of the herbicide of the formula (A1) (flupyrsulfuron) or herbicidal salts thereof ##STR1## on crops, preferably cereals and maize, can be prevented by combining the herbicides with safeners (B) from the groupa) compounds of the formulae (B1) and (B2), ##STR2## in which W is a divalent heterocyclic radical from the group of the partially unsaturated or heteroaromatic five-membered heterocycles having 1 to 3 hetero ring atoms of the type N and O, at least one nitrogen atom and at the most one oxygen atom being present in the ring, andX, n, Z, R*, and W are as defined in claim 1, and/orb) compounds of the group of the hormonal growth regulators (auxins).
摘要:
Compounds of formula (I), where R.sup.1, R.sup.2, n, W, R.sup.3 and A are as defined in claim 1, are suitable for use as herbicides and plant growth regulators. They can be produced by a process similar to known processes. To produce them, new compounds of formula (II) are reacted with a carbamate of formula R*--O--CO--NR.sup.3 A, where R.sup.3 stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.
摘要:
Herbicide/safener combinations ofA) herbicides selected from the group of the 2-acylated 1,3-dicarbonyl compounds or salts thereof, andB) safeners B1 and/or B2 ##STR1## as they are defined in claim 1, are suitable for controlling harmful plants in crops such as cereals, maize and rice.
摘要:
Compounds of the formula I ##STR1## where R.sup.1 to R.sup.9 are as defined in claim 1 are known as herbicides. When these compounds are applied in traditionally used amounts, this often results in damage to crop plants in the crops, when it is desired to achieve sufficient action against weeds typically occurring therein. However, according to the invention it is possible to reduce the application rates to 0.001 to 0.5 kg of a.i./ha in rice growing, and the action obtained against important harmful plants in rice from the species Sagittaria, Cyperus and Scirpus Eleocharis is nevertheless sufficient.

摘要:
Compounds of the formula I or salts thereof ##STR1## where R.sup.1 is H or an aliphatic radical; R.sup.2 and R.sup.3 are H, alkyl or phenyl; W is O, S, NR.sup.4 or NOR.sup.4 ; X is CHR.sup.2, O or NR.sup.4 ; L is a (substituted) phenyl, naphthyl or monocyclic heteroaryl radical, A is a (substituted) pyrimidyl, triazinyl, triazolyl or bicyclic heteroaryl radical, and m and n are 0 or 1, have advantageously herbicidal or plant growth-regulating properties.
摘要:
Compounds of the formula I or their salts ##STR1## wherein R.sup.1 denotes substituted alkyl; (subst.) alkenyl; (subst.) alkynyl; R.sup.2 denotes halogen; nitro; (subst.) alkyl or (subst.) alkoxy; R.sup.3 denotes hydrogen; alkyl; alkenyl or alkynyl; R.sup.4 denotes a heterocyclic radical or the formulae ##STR2## where E is CH or N; and n denotes 0, 1, 2 or 3, possess excellent herbicidal and plant growth-regulating properties.
摘要:
The compounds of the general formula (I) ##STR1## in which X denotes 0 or --SO.sub.2 --, Y denotes CH or N, R.sub.1 denotes alkyl, alkenyl or (C.sub.2 -C.sub.6)-alkinyl which are optionally substituted, R.sub.2 denotes alkyl, alkenyl, alkinyl or cyclohexyl, R.sub.3 and R.sub.4 denote H or alkyl, and R.sub.5 and R.sub.6 denote H, (substituted) alkyl, (substituted) alkoxy, halogen, alkylthio, monoalkylamino or dialkylamino, and also salts thereof, possess advantageous herbicidal properties against monocotyledonous and dicotyledonous weeds and are suitable for selective use in large-scale crops. In addition, they possess a good plant growth-regulating action.
