Abstract:
Herbicides containing in combination(A) compounds of the formula I ##STR1## in which R is chlorine or bromine,X is oxygen or sulfur, andR.sub.1 is hydrogen, (C.sub.1 -C.sub.4)-alkyl or a cation equivalent; and(B) compounds of the formulae ##STR2## as active components, the weight ratio of components A to B being preferably from 5:1 to 1:20. These herbicidal combinations are distinguished by a synergistic effect, especially against weed grasses in crop plants.
Abstract:
Phenoxyphenoxy-propionic acid derivatives of the formula ##STR1## exhibit an outstanding herbicidal activity against a wide variety of weed grasses and are well tolerated by dicotyledonous crop plants and various cereals.
Abstract:
Phenoxy-phenoxypropionic acid derivatives of the formula ##STR1## wherein R is hydrogen or halogen, and R.sub.1 is substituted alkyl, cyclohexenyl, phenylalkenyl or (substituted) alkinyl, are interesting selective herbicides having a special activity against weed grasses. They are obtained for example by reaction of corresponding phenoxypropionic acid halides with hydroxy compounds of the formula HO--R.sub.1.
Abstract:
Compounds of the formula I ##STR1## in which R denotes halogen, hydroxyl, cyano, nitro, (substituted) alkyl, (substituted) alkoxy, (halo)alkylthio, carboxyl, alkoxycarbonyl; (halo)alkylsulf(inyl) (onyl) or -(onyloxy); (halo)phenyl or (halo)phenoxy; X in the 3- or 5-position denotes a (thio)carboxylic acid--or an optionally heterocyclic radical which is derived therefrom; Y denotes halogen, m denotes the number 0 or 1, and n denotes a number from 0 to 5, have valuable plant growth-regulating properties and are suitable, in addition, as safeners for protecting crop plants against phytotoxic side effects of herbicides.
Abstract:
The compounds of the formula I ##STR1## wherein R denotes (substituted) phenyl, (substituted) cyclohexyl or (substituted) cyclohexenyl,X denotes a radical of the formulae ##STR2## Y denotes a radical of the formulae ##STR3## and the bisulfite adducts, acetals, ketals, thioacetals or thioketals derived from ##STR4## Z denotes O, S or N--R.sup.8, m denotes 0, 1 or 2, n denotes 0, 1, 2, 3, or 4 and p denotes 2 or 3,and their salts and quaternization products which are acceptable for agricultural purposes possess advantageous plant growth-regulating actions.
Abstract:
The new compounds of the formula I or salts thereof ##STR1## in which R denotes a (substituted) cyclohexyl radical or a (substituted) cyclohexenyl radical; and Y denotes cyano, a (substituted) (di)(thio)carboxylic acid (ester), carboxamide or acetal radical, a keto or oxime radical or a heterocyclic radical, possess an advantageous action as plant growth-regulators and, in addition, have favorable herbicidal and fungicidal properties.
Abstract:
Compounds of the formula ##STR1## in which A denotes --CH.sub.2 -- or --CH(CH.sub.3)-- and Z denotes a carboxyl group or a (thio)carboxylic ester group, are effective antidotes for the herbicide Fenoxaprop-ethyl.
Abstract:
Compounds of the formula I ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 independently of one another denote hydrogen, F, Cl, Br or (C.sub.1 -C.sub.4)-alkyl, and R.sup.1 also denotes CF.sub.3, CN, NO.sub.2 or alkoxycarbonyl, A denotes a direct bond, --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--, X denotes O, S or N--R.sup.8, R.sup.4 denotes H or alkyl, R.sup.5 and R.sup.6 denote alkyl, R.sup.7 denotes alkyl, (substituted) benzyl and/or (substituted) phenethyl and R.sup.8 denotes H or alkyl or, together with NR.sup.7, denotes a heterocyclic ring, are active herbicides and antidotes.
Abstract:
Heterocyclic phenyl ethers of the formula ##STR1## in which (R).sub.n is hydrogen or up to three identical or different substituents selected from halogen, CF.sub.3, NO.sub.2, CN, alkyl, alkoxy and alkylthio, and A is oxygen, sulfur or N(C.sub.1 -C.sub.4)alkyl, provided that the --OH group is not in para-position if (R).sub.n is hydrogen and A is sulfur, are useful as starting materials for the manufacture of selective herbicides.
