Embodiment 1

[0051] Example 1: 42% pyridaben-flumefeline wettable powder (20:1)

[0052] Proportion: pyridaben 40%; trifluroxyfen 2%; wetting agent sodium lauryl sulfate 2%; dispersant calcium lignosulfonate 8%; filler white carbon black 18%, filler kaolin balance .

Embodiment 2

[0053] Example 2: 60% pyridaben-triflumeyle wettable powder (9:1)

[0054] Proportion: Pyridaben 54%; Trifluroxyfen 6%; Wetting agent sodium lauryl sulfate 2%; Dispersant calcium lignosulfonate 8%; Filler white carbon black 18%, Filler kaolin balance .

Embodiment 3

[0055] Example 3: 45% pyridaben-triflumeyle wettable powder (8:1)

[0056] Proportion: Pyridaben 40%; Trifluroxyfen 5%; Wetting agent sodium lauryl sulfate 2%; Dispersant calcium lignosulfonate 8%; Filler white carbon black 18%, Filler kaolin balance ;

[0057] The preparation method of Examples 1-3 is as follows: according to the above ratio, the active ingredients pyridaben and flumefeline are added to the carrier, and surfactants and other functional additives are added therein, mixed, and air-jet milled Then mixed to obtain a wettable powder. The main equipment is a mixer and a jet mill.

Abstract

The invention provides an insecticidal composition and an application thereof, and belongs to the field of insecticides. After effective components pyridaben and pyridalyl are selected and compounded,the insecticidal spectrum can be effectivley expanded, the control effect is improved, the appropriate application period is prolonged, the dosage is reduced, phytotoxicity is reduced, residues are reduced, and generation of drug resistance of pests is delayed. The insecticidal composition comprises effective components and auxiliary components, wherein the effective components are pyridaben andpyridalyl, the weight ratio of pyridaben to pyridalyl is 40:1-1:40, the weight percentage content of the pyridaben and the pyridalyl as the effective components is 1-80%, the auxiliary components comprise a carrier and an auxiliary agent, the carrier is one or more of water, a solvent or a filler, and the auxiliary agent at least comprises a surfactant. The insecticidal composition can effectivelyprevent and treat whitefly, leafhopper and aphid, and also has good control effects on lepidoptera pests such as beet armyworm, plutella xylostella, homoptera and coleopteran pests.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of insecticides, in particular to an insecticidal composition and its application. Background technique [0002] In the process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the problem of pest resistance is most likely to occur through chemical control of pests, and long-term, continuous and high-dose application of a single chemical insecticide is likely to cause A series of problems such as drug residues and environmental pollution. One of the ways to solve the above problems is to develop new insecticides. However, the development cost of new active ingredients is high, the development cycle is long, and they can never keep up with the speed of pest resistance, so it is difficult to really apply them in actual production. [0003] Pyridaben is a respiratory system inhibitor, w...
