摘要:
Disclosed are compounds of formula (I) in which R1-R5, X, W, n and Z have the definitions indicated in claim 1. These compounds are particularly suitable for use as selective herbicides in crop cultures.
摘要:
The invention concerns compounds of formula (I), or salts thereof0, in which G is a group of the formula G?1, G2 or G3; R1¿ is H or alkyl; R2 is COOH, CSOH or a carboxylic- or thiocarboxylic-group derivative with 1 to 20 C-atoms or an acyl group of the CO-Ro type with 1 to 12 C-atoms or an imino, hydrazone or oxime derivative of the CO-Ro group, and R?o, R3a, R4a, R3b, R4b¿, W, X, Y and Z are as defined in claim 1. Such compounds are suitable for use as selective herbicides and plant-growth regulators in agricultural crop plants. They can be prepared by prior art methods via intermediates, some of which are novel, from the group comprising the benzenesulphonamides (II), benzenesulphonyliocyanates (IV), benzenesulphochlorides (VI) and heterocyclically substituted carbamates (III), amines (V) or [thio]isocyanates (XIX).
摘要:
Protectors against phytotoxic side-effects of pesticides in culture plants are compounds of formula (I) and their salts, in which R1 is hydrogen, a hydrocarbon, a hydrocarbon thio radical or a heterocyclyl radical, in which each of the four last-mentioned radicals may be unsubstituted or substituted by one or more identical or different radicals from the group halogen, cyano, nitro, amino, hydroxy, carboxy, formyl, carbonamide, sulphonamide and radicals of the formula -Z?a-Ra, R2¿ is hydrogen or (C¿1?-C4) alkyl, or R?1 and R2¿ together with the group of the formula -CO-N- are the radical of a 3 to 8-member saturated or unsaturated ring, and R3 to R5, n and m have the meanings given in claim 1. The compounds may be produced by the process claimed in claim 8.
摘要:
The invention concerns compounds of formula (I) and their salts, in which formula R1 to R9, X, Y, n and m are defined as in claim 1, which are suitable as herbicides and plant-growth regulators. They can be prepared by processes as defined in claim 6 by means of intermediate products of formula (IV), some of which are novel.
摘要:
The invention concerns a method of controlling weeds in rice crops, the method being characterized in that one or more compounds of the formula (I), in which R1 is an acyl group selected from the series CO-R?2, CS-R2, CO-OR3, CS-OR3, CO-SR4, CS-SR4, CO-NR5R6¿ and CS-NR?5R6, and R2, R3, R4, R5 and R6¿ and X, Y and Z compounds, are defined as in formula (I) in claim 1, or the salts of such compounds, are applied to the area containing the weeds and rice plants or their seeds, in an effective amount from 0.0001 to 0,5 kg of active ingredient/hectare. These compounds (I) are per se prior art. The invention also concerns, however, the salts of the compounds (I), which are novel.
