    • A method is described for the control of nematodes and soil-borne insects in agricultural crops which comprises applying to the situs of infestation a composition containing as active ingredient a compound of the formulaR--Z--(CH.sub.2).sub.n --Qwherein R is an alkyl radical of one or two carbon atoms carrying one-to-four fluorine substituents and one-to-three chlorine or bromine substituents represented as CF.sub.p X.sub.(3-p) -- or CF.sub.r X.sub.(3-r) --CF.sub.s X.sub.(2-s) --; Z is --(CH.sub.2 --CHX)-- or --(CH.dbd.CH)--; X is chlorine or bromine; Q is methyl, isopropyl, tert-butyl, or C.sub.3 -C.sub.6 cycloalkyl; n is 5 to 12 as required to yield in the compound a chain of 10 to 16 carbon atoms; p is 1 or 2; r is 2 or 3; s is 0 or 1 or 2. A process for preparation of active ingredient compounds is described, and utility of compositions against nematodes and soil-borne insects is exemplified.
    • 描述了一种用于控制农作物中的线虫和土传昆虫的方法,其包括向侵染地点施用含有式RZ-(CH2)nQ的化合物作为活性成分的组合物,其中R是一个烷基 或具有一至四个氟取代基的两个碳原子和表示为CFpX(3-p) - 或CFrX(3-r)-CFX(2-s) - 的一至三个氯或溴取代基; Z是 - (CH 2 -CHX) - 或 - (CH = CH) - ; X是氯或溴; Q是甲基,异丙基,叔丁基或C 3 -C 6环烷基; 根据需要,n为5至12,以在化合物中产生10至16个碳原子的链; p为1或2; r为2或3; s是0或1或2.描述了制备活性成分化合物的方法,并且例示了针对线虫和土传昆虫的组合物的效用。
