摘要:
The invention relates to combinations of sulfonylurea herbicides (A) and their salts in which R2 is H, OH, aliphatic hydrocarbon radical or hydrocarbon-oxy radical, and R1 is an acyl radical, and the other symbols are as defined in claim 1, and safeners of type (B1) and (B2) in which the symbols are as defined in claim 1.
摘要:
The present invention relates to a liquid adjuvant comprising a) one or more surfactants of the formula (I), Ar—O—(CHR1—CHR2—O—)y—R3 (I)where Ar is aryl which is substituted by at least two (C1-C30)alkyl radicals, R1 is H or (C1-C6)alkyl, R2 is H or (C1-C6)alkyl, R3 is H, an unsubstituted or substituted (C1-C30) hydrocarbon radical, a sulfonate radical, a phosphonate radical or an acyl radical, and y is an integer from 1 to 100, and b) one or more fatty acid esters. The adjuvant is particularly suitable in the field of crop protection.
摘要:
Surfactant/solvent systems for liquid organic formulations (preparations) which comprise one or more aromatic-based surfactants and one or more completely esterified organic phosphates and/or phosphonates which are as polar as possible, but are at the same time water-insoluble or soluble in water to 5 g/l, as solvents, are suitable to be used for the preparation of emulsifiable concentrates and corresponding liquid preparations derived therefrom, such as aqueous spray mixtures.
摘要:
Acylated aminophenylsulfonylureas, processes for their preparation and their use as herbicides and plant growth regulators. Compounds of the formula (I) and salts thereof ##STR1## in which W.sup.1, W.sup.2, R, n, R.sup.1, R.sup.2, R.sup.4, X, Y and Z are as defined in claim 1 and R.sup.3 is an acyl radical, are suitable as herbicides and plant growth regulators. The herbicides can be prepared by the process variants from claim 5, the novel intermediate products (II), (IV), (VI) and (VIII)* of claims 9 and 10 being employed.
摘要:
Salts of the formula (I) ##STR1## in which n is 0, 1, 2 or 3, R is halogen, alkyl or alkoxy, mainly in each case independently of other substituents R in the event that n is greater than 1, R.sup.1 is a substituted or unsubstituted hydrocarbon radical or a substituted or unsubstituted heterocyclic radical, R.sup.2 is an acyl radical, R.sup.3 is hydrogen or C.sub.1 -C.sub.5 -alkyl, M.sym. is a metal or ammonium ion, X and Y independently of one another are halogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy or C.sub.1 -C.sub.6 -alkylthio, each of the three last-mentioned radicals being unsubstituted or substituted by one or more radicals selected from the group consisting of halogen, C.sub.1 -C.sub.4 -alkoxy and C.sub.1 -C.sub.4 -alkylthio, or are C.sub.3 -C.sub.6 -cycloalkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkynyl, C.sub.3 -C.sub.6 -alkenyloxy, C.sub.2 -C.sub.6 -alkynyloxy, mono- or di(C.sub.1 -C.sub.4 -alkyl)amino, and Z is CH or N, are suitable as herbicides and plant growth regulators, The compounds (I) can be prepared by processes of claims 5 to 7, for example by hydrogenating 2-alkoxycarbonyl-5-nitrophenylsulfonylureas in the presence of anhydrides.
