PURPOSE:The titled composition that contains, as active ingredients, an N- substituted chloroaectanilide and a urea derivative, thus having a wide range of weed-killing spectra and controlling effectively prennial weeds and broad-leaf weeds such as MIZUGAYATSURI (a kind of kyllinga) or URIKAWA (arrow head) with reduced doses. CONSTITUTION:The objective composition contains, as active ingredients, an N-substituted chloroacetanilide of formula I (R1-R3 are H, halogen, alkyl, alkoxy, alkylthio, alkoxyalkyl, alkylthioalkyl; R4 is H, alkyl; R5-R7 are H, halogen, alkyl, alkenyl, alkinyl, alkoxy, alkylthio) and a urea derivative of formula II (R8 is alkyl, phenyl; R9, R10 are alkyl; R11 is H, alkyl; R12, R13 are H, halogen, alkyl) at a weight ratio of 1:(0.01-50), preferably 1:20. |
