DESCRIPTION:
BRIEF SUMMARY
This application has been filed under 35 USC 371 from international application PCT/EP93/01732, filed Jul. 5, 1993 and published as WO94/02014 Feb. 3, 1994.
The invention relates to novel herbicidal, synergistic combinations of the known heteroaryloxyacetamides on the one hand and further known herbicides belonging to other classes of substances on the other hand, which can be particularly advantageously used for selectively combatting weeds in various crops/plants.
The patent specifications cited below describe heteroaryloxyacetamides which are preferentially effective against monocotyledon weeds (=grass weeds) but also against some dicotyledon weeds. They exhibit practically exclusively soil activity and only slight activity via the foliage, and some of them have a high selectivity in mono- and dicotyledon crop plants, such as cereals, maize, rice, soya bean and cotton [cf. for example EP-A 5 501 (=U.S. Pat. No. 4,509,971 and U.S. Pat. No. 4,833,243); EP-A 18 497 (=U.S. Pat. No. 4,645,525 and U.S. Pat. No. 4,756,741); EP-A 29 171 (=U.S. Pat. No. 4,408,055); EP-A 94 514 (=U.S. Pat. No. 4,585,471); EP-A 100 044 (=U.S. Pat. No. 4,549,899); EP-A 100 045 (=U.S. Pat. No. 4,540,430); EP-A 161 602 (=U.S. Pat. No. 4,784,682); EP-A195 237 (=U.S. Pat. No. 4,788,291); DE-A 3 724 467; EP-A 348 734 (=U.S. Pat. No. 4,988,380); EP-A 348 737 (=U.S. Pat. Nos. 4,968,342 and 5,090,991); DE-A 4 113 421 and DE-A 4 137 827, as well as WO 91/06544].
Surprisingly, biological experimentation has now uncovered a number of known herbicidally active compounds from the classes of the phenyl- and benzthiazolyl-ureas, imidazolinones, pyridinecarboxamides and diphenyl ethers which, when used together with the abovementioned heteroaryloxyacetamides, possess extremely synergistic properties with regard to the effectiveness against weeds and can be used particularly advantageously, that is to say as broadly effective combination preparations, for selectively combatting weeds--both monocotyledon and dicotyledon weeds, by the preemergence and postemergence methods--in monocotyledon and dicotyledon crop plants, such as, for example, maize, wheat, barley, rice, soya bean, cotton, beet and peanuts, so that a number of economically important (problem) weeds and grass weeds can be reliably controlled.
The present invention provides herbicidal synergistic agents, characterised by an effective content of an active ingredient combination consisting of ##STR2## in which Het represents an optionally substituted heteroaromatic radical from the series consisting of 1,3-thiazol-2-yl, 1,2,4-thiadiazol-2-yl, 1,3,4-thiadiazol-2-yl, benzoxazol-2-yl and benzothiazol-2yl. C.sub.1 --.sub.4 -alkoxy, each of which is optionally substituted, and phenyl, each of which is optionally substituted, (=active ingredients of group 1) and the compound classes (a) to (i) mentioned below: 3-(4-isopropylphenyl)-1,1-dimethylurea (ISOPROTURON), 3-(3-chloro-4-methylphenyl)-1,1-dimethylurea (CHLORTOLURON), 3-(3,4-dichlorophenyl) -1,1-dimethylurea(DIURON),3-(4-chlorophenyl) -1,1-dimethylurea (MONURON), 3-(3,4-dichlorophenyl) -1-methoxy-1-methylurea (LINURON), 3-(4-chlorophenyl)-1-methoxy-1-methyl-urea (MONOLINURON) or 3-(3-trifluoromethyl-phenyl) -1,1-dimethylurea (FLUOMETURON); 3-(benzthiazol-2-yl)-1,3-dimethyl-urea (METHABENZTHIAZURON); N,N-di-(n-propyl)-2,6-dinitro-4-trifluoromethylaniline (TRIFLURALIN) or N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitroaniline (PENDIMETHALIN); 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (ATRAZINE), 2-chloro-4-(1-cyano-1-methylethyl-amino)-6-ethylamino-s-triazine (CYANAZINE). 2-Chloro-4-ethylamino-6-tert.butylamino-s -triazine (TERBUTHYLAZINE), 2-ethylamino-4-methylthio -6-tert.butylamino-s-triazine (TERBUTRYN) or2-chloro-4,6-bis-(ethylamino)-s-triazine (SIMAZINE); 4-amino-6-tert.-butyl-3-methylthio-1,2,4-triazin -5-(4H)-one (METRIBUZINE), 3-methyl-4-amino-6-phenyl-1,2,4-triazin-5-(4H)-one (METAMITRON) or 4-amino-6-tert.-butyl-3-ethylthio-1,2,4-triaxin -5(4H)-one (ETHIOZINE); 3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-1-(2-chlorophenyl)-sulphony
