Abstract:
The compounds of formula I ##STR1## in which the substituents X, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6, are defined hereinbelow. The compounds have advantageous herbicidal properties and are useful, for example, for combating undesired plants.
Abstract:
Compounds of the formulaAr--O--A--Zin which Ar denotes an optionally substituted phenyl-A--CH.sub.2 -- or phenyl-A--CH(CH.sub.3)-- or naphthyl-A--CH.sub.2 -- or naphthal-A--CH(CH.sub.3)-- group and Z denotes, inter alia, a carboxyl, (thio)carboxylic ester or carboxamide group, a cyclic imino(thio)ether group or an open or cyclic acetal group, are effective antidotes, in particular for herbicides belonging to the group comprising phenoxyphenoxypropionic acid esters and hetero-aryloxyphenoxypropionic acid esters.
Abstract:
Compounds of the formula ##STR1## wherein R is halogen, CF.sub.3, NO.sub.2, CN, Alkyl or alkoxy, n is 0 to 3 X is O, S, NH or N-Alkyl, Y is O, S, SO, SO.sub.2, NH or N-Alkyl, R.sub.1 is H or alkyl and Z is carboxy or hydroxymethyl or functional derivatives of these groups, are valuable herbicides and growth regulators.
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:
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.
