The invention relates to substituted phenoxypropionaldehyde derivatives having the general formula
wherein:
W and W¹ are independently O, S or NH;
X is CY, N or N⊕ - O⊖;
Q is N or N⊕ - 0⊖;
Z is CH or N;
Y is hydrogen, halogen, cyano, nitro or haloalkyl of up to 10 carbon atoms;
Y¹ and Y² are independently hydrogen, halogen, nitro, cyano or a radical of up to 4 carbon atoms selected from alkyl, haloalkyl and alkoxy;
R is hydrogen or a radical of up to 4 carbon atoms selected from alkyl, haloalkyl and alkoxy;
R¹ is cyano, vinyl, acetynyl, dialkylphosphinyl or dialkylphosphonyl; and
R² is - OR³, -SR³ or -NR⁴R⁵ wherein
R³ is hydrogen, a radical of up to 10 carbon atoms selected from alkyl, cycloalkyl, haloalkyl, hydroxyalkyl, oxoalkyl, alkoxyalkyl, alkenyl and alkynyl, or Ar, -COR⁶ or -CSR⁶
wherein R⁶ is a radical of up to 10 carbon atoms selected fron alkyl, cycloalkyl, haloalkyl, theoalkyl, alkoxy, alkenyloxy and alkynyl, or phenoxy, amino, Ar, -COOR⁷ or -COSR⁷ wherein R⁷ is hydrogen, alkali metal, a radical of up to 10 carbon atoms selected from alkyl, cycloalkyl, haloalkyl, alkenyl and alkynyl, or Ar; and
R⁴ and R⁵ are independently hydrogen or alkyl of up to 10 (preferably up to 4) carbon atoms; formulations of such derivatives and the use thereof for pre-emergence or post-emergence control of noxious plants, namely weed.
