Problems solved by technology

[0010] However, in actual agricultural production, underground pests and nematodes often occur mixedly on crops, requiring repeated use of pesticides for control, which increases the use of pesticides, increases the production cost of crops, and increases pesticide residues on crops, increasing the the degree of pollution to the environment

Abstract

The invention discloses a pesticide composition containing fluensulfone and pyrethroid insecticide. The composition comprises a first effective ingredient fluensulfone, a second effective ingredient pyrethroid insecticide and common pesticide auxiliaries, wherein the pyrethroid insecticide is one of tefluthrin, beta-cyfluthrin, cyfluthrin, lambda-cyhalothrin and bifenthrin; and the weight ratio of fluensulfone to pyrethroid insecticide is (40:1)-(1:40). Massive indoor and outdoor tests indicate that the pesticide composition has a remarkable synergetic effect, and has a preventing and controlling effect on underground pests and nematodes on crops remarkably superior to those of independent application of single agent, so that the pesticide usage is reduced, residues of pesticide on crops are reduced, environmental pollution is reduced, and generation of drug resistance of pests and insects is retarded.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a pesticide composition with fluthiazol and pyrethroid insecticides as active ingredients, which is used to prevent and control underground pests and nematodes of crops. Background technique [0002] Fluensulfone: It is a new type of non-fumigation nematicide, which has a good control effect on nematodes in all growth stages. Usually the mode of action of non-fumigation nematicides is to incapacitate the nematodes, but after a period of time the nematodes will revive, while fluthiazide sulfone completely kills the nematodes. The entry time of fluthiazol into the soil is only 12 hours, while the entry time of other nematicides is generally about 5 days. [0003] Tefluthrin: It belongs to pyrethroid insecticides, which can effectively control Coleoptera, Lepidoptera and some Diptera pests that inhabit the soil, such as pumpkin twelve star beetle, golden needle b...
