摘要：
The object of the present invention is composed of a lactone ring-containing nematicide and a method of preparation and use thereof, wherein the nematicide comprises hydrogen, cyano, fluorine, chlorine, bromine, an alkyl containing 1 to 4 carbon atoms, a alkoxy containing 1 to 4 carbon atoms, alkoxyphenyl, an alkoxy containing 1 to 4 carbon atoms and one hydrogen atom at the carbon atom substituted by one or more chlorine atoms, an alkoxy containing 1 to 4 carbon atoms and one atom hydrogen at the carbon atom substituted by one or more fluorine, nitro or amino atoms； and r6 is selected from hydrogen, fluorine and chlorine. The invention has a good control effect on the eggs and juveniles of the second stage radical node nematode stages and, in particular, can completely inhibit the incubation of cucumber, tomato, tobacco, soybean and other nematode eggs. lineage； during use over a long period of time, pests do not produce antibodies against the nematicide of the present invention, and it has a good nematicidal effect； Also provided in the invention is a method for preparing the lactone ring-containing nematicide, wherein the preparation method has few steps and the process is easy to operate and is suitable for large scale industrial production.o objeto da presente invenção são compostos de um nematicida contendo um anel de lactona e um método de preparação e seu uso, em que o nematicida compreende hidrogênio, ciano, flúor, cloro, bromo, um alquilo contendo 1 a 4 átomos de carbono, um alcoxi contendo 1 a 4 átomos de carbono, alcoxifenilo, um alcoxi contendo 1 a 4 átomos de carbono e um átomo de hidrogénio no átomo de carbono substituído por um ou mais átomos de cloro, um alcoxi contendo 1 a 4 átomos de carbono e um átomo de hidrogénio no átomo de carbono substituído por um ou mais átomos de flúor, nitro ou amino； e r6 é selecionado de hidrogênio, flúor e cloro. a invenção tem um bom efeito de controle sobre os ovos e os juvenis dos estádios do segundo estágio de nem
