SELECTIVE HERBICIDES BASED ON ARYLSULPHONYLAMINOCARBONYLTRIAZOLINONES

摘要

The novel herbicidally active compound combinations comprising (a) an arylsulphonylaminocarbonyltriazolinone of the formula (I)(in which R1, R2, R3 and R4 are each as defined in the description) and/or a salt of a compound of the formula (I) (="active compound of Group 1") and (b) one or more compounds from a second group of certain known herbicides (="active compound of Group 2") exhibit at certain weight ratios synergistic effects and can be employed as selective herbicides in various crops of useful plants;typical examples are active compound combinations from the Na salts of the compounds of the formula (I) where R1=CH3, R2=OC3H7, R3=COOCH3 and R4=H (I-1) or where R1=CH3, R2=OCH3, R3=OCF3 and R4=H (I-2) as active compound of Group 1 and metribuzin as active compound of Group 2.
