摘要:
Heteroaryloxy-acetamides of the general formula (I) ##STR1## in which Het represents thiadiazolyl which is substituted by halogen or by C.sub.1 -C.sub.4 -alkyl or phenyl, each of which is optionally substituted by halogen, andAr represents optionally halogen-, C.sub.1 -C.sub.4 -alkyl- or C.sub.1 -C.sub.4 -halogenoalkyl-substituted phenyl.can be used with good results as selective herbicides in rice cultivation.The novel herbicidal active compound combinations comprising (1) a heteroaryloxy-acetamide of the formula (I) above and (2) in each case one active compound from the group of already known selective rice herbicides (e.g. bensulfuron, MCPB, and thiobencarb) exhibit, at certain weight ratios, synergistic activities and can be used particularly advantageously as selective herbicides in rice crops.
摘要:
The novel herbicidally active compound combinations comprising (a) 1-(2-chloro-phenyl)-4-(N-cyclohexyl-N-ethyl-aminocarbonyl)-1,4-dihydro-5H-tetrazol-5-one and (b) N-(3,4-dichloro-phenyl)-propanamide (Propanil) exhibit synergistic activity at certain weight ratios and can be employed as selective herbicides in a variety of crops (for example rice and wheat).
摘要:
The invention relates to novel herbicidal synergistic active compound combinations comprising a known tetrazolinone derivative and known herbicidally active compounds and/or safeners, which compositions can be used with particularly good results for the selective control of weeds in various crops of useful plants.
