Nematodes and insects are controlled by application of vinyl fluorides of the formula ##STR1## where R is CH.sub.2 X--, CHX.sub.2 --, CX.sub.3 --, XCH.dbd.CH--, CH.sub.2 .dbd.CX-- or straight chain alkyl(C.sub.2 -C.sub.8); R.sup.1 is hydrogen, fluoro, chloro, bromo, CH.sub.2 Z--, CHZ.sub.2 -- or CZ.sub.3 --; R.sup.2, X and Z independently are hydrogen, fluoro, chloro or bromo; Y.sup.1, Y.sup.2, Y.sup.3, and Y.sup.4 independently are CH.sub.3 or any value of R.sup.2, 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.
应用化学式为##STR1##的乙烯氟化物可以控制线虫和昆虫,其中R为CH.sub.2 X--,CHX.sub.2 --,CX.sub.3 --,XCH.dbd.CH--,CH.sub.2 .dbd.CX--或直链烷基(C.sub.2-C.sub.8); R.sup.1为氢,氟,氯,溴,CH.sub.2 Z--,CHZ.sub.2 --或CZ.sub.3 --; R.sup.2,X和Z独立地为氢,氟,氯或溴; Y.sup.1,Y.sup.2,Y.sup.3和Y.sup.4独立地为CH.sub.3或R.sup.2,X和Z的任何值; a为0-12; n为7-13; 并且n大于a。特定的物种包括根结线虫,萎缩线虫,病斑线虫,囊泡线虫和自由生活线虫以及南方玉米根虫。这些乙烯氟化物也具有驱虫作用。
