摘要：
FIELD: agriculture.SUBSTANCE: invention relates to agriculture. For controlling aquatic weeds in a body of water the method comprises providing in the body of water a composition comprising a herbicidally effective amount of a compound of formula I ,wherein Q1 represents H or F； Q2 represents halogen with the proviso that when Q1 is H, then Q2 is Cl or Br； R1 and R2 independently represent H, C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, hydroxy group, C1-C6-alkoxy, amino group, C1-C6-acyl, C1-C6-carbalkoxy group, C1-C6-alkylcarbamyl, C1-C6-alkylsulfonyl, C1-C6-trialkylsilyl or C1-C6-dialkylphosphonyl or R1 and R2, taken together with the N atom represent a 5- or 6-membered saturated ring； and Ar represents a polysubstituted aryl group selected from the group consisting of a) wherein W1 represents halogen； X1 represents F, Cl, C1-C4-alkyl, C1-C4-alkoxy group, C1-C4-alkylthio group, C1-C4-alkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4-haloalkyl, C1-C4-haloalkoxy group, C1-C4-alkoxy-substituted C1-C4-alkyl, C1-C4-alkoxy-substituted C1-C4-alkoxy group, -CN, -NR3R4, or fluorinated acetyl, or propionyl； Y1 represents C1-C4-alkyl, C1-C4-haloalkyl, halogen or -CN or, ifX1 and Y1 are taken together, represents -O(CH2)nO-, where n=1 or 2； and R3 and R4 independently represent H or C1-C4-alkyl； b) wherein W2 represents F or Cl； X2 represents F, Cl, -CN, -NO2, C1-C4-alkyl, C1-C4-alkoxy group, C1-C4-alkylthio group, C1-C4-alkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4-haloalkyl, C1-C4-haloalkoxy group, C1-C4-alkoxy-substituted C1-C4-alkyl, C1-C4-alkoxy-substituted C1-C4-alkoxy group, -NR3R4, or fluorinated acetyl, or propionyl； Y2 represents halogen, C1-C4-alkyl, C1-C4-haloalkyl or -CN,or, if W2 represents F, X2 and Y2, taken together, represent -O(CH2) nO-, where n=1 or 2； and R3 and R4 independently represent H or C1-C6-alkyl； and c) wherein Y3 represents halogen, -CN or -CF3； Z3 represents F, Cl, -CN, -NO2, C1-C4-alkyl, C1-C4-alkoxy group, C1-C4-alkylthio group, C1-C4-alkylsulfinyl,
