<p>A herbicide composition, particularly effective for the post-emergence deweeding of sugarbeet, forage beet and vegetable beet, is obtained by mixing with inert substances and adjuvants the compound of formula: <CHEM> with one or more compounds of formula: <CHEM> where R1 and R2 can be alkyls with 2-4 carbon atoms, or R1 and R2 may form a nitrogenous heterocyclic ring with 5 or 6 carbon atoms; and A can be alkyl with 2-4 carbon atoms, or benzyl eventually replaced by halogens on the ring, or even 1,1-dimethylbenzyl eventually replaced by halogen; possibly also adding one or more compounds of formula: <CHEM> where R4 and R5 are alkyls with 1-4 carbon atoms; B can be -CH2-O-, -CH2-CH2-O-, <CHEM> R3 is alkyl with 1-4 carbon atoms; and X can be chlorine or bromine.</p> |
