Nematodes and insects are controlled by application of vinyl fluorides of the formula <IMAGE> where R is CH2X-, CHX2-, CX3-, XCH=CH-, CH2=CX- or straight chain alkyl(C2-C8); R1 is hydrogen, fluoro, chloro, bromo, CH2Z-, CHZ2- or CZ3-; R2, X and Z independently are hydrogen, fluoro, chloro or bromo; Y1, Y2, Y3, and Y4 independently are CH3 or any value of R2, X and Z; a is 0-12; n is 7-13; and n is greater than a. Particular species controlled are the root-knot, stunt, lesion, cyst and free-living nematodes, and the southern corn rootworm. The vinyl fluorides also have anthelmintic utility. |
