Substituted 2,3-dihydrobenzofurylmethyl esters of the formula I I where where R8 is hydrogen or alkyl of up to 5 carbon atoms, R9 is alkyl, haloalkenyl or haloalkynyl, each of up to 5 carbon atoms, R10 is halogen or alkyl of up to 5 carbon atoms, R11 is halogen or alkyl of up to 5 carbon atoms, A is halogen, alkyl, alkoxy, trihaloalkyl or trihaloalkoxy, each of up to 5 carbon atoms, cyano or nitro, B is alkyl, alkenyl or alkynyl, each of up to 4 carbon atoms, or an alicyclic radical of 3 to 7 carbon atoms and n is from 0 to 3, R2 is hydrogen, cyano or alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms, and R3, R4, R5, R6 and R7 are identical or different and each is hydrogen, halogen or alkyl, alkenyl, alkynyl or alkoxy, each of up to 5 carbon atoms, and R9 may also be alkenyl of up to 5 carbon atoms if R2 is cyano or is alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms. The novel compounds are useful in pest control.
