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.
线虫和昆虫通过应用以下公式的乙烯氟化物来控制##STR1##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或任何R.sup.2、X和Z的值;a为0-12;n为7-13;且n大于a。特定被控制的物种包括根结线虫、矮化线虫、病斑线虫、囊线虫和自由生活线虫,以及南部玉米根甲虫。这些乙烯氟化物还具有驱虫作用。
