Pesticide composition containing chromafenozide

Abstract

The invention discloses a pesticide composition containing chromafenozide. The insecticidal composition contains an active component A and an active component B, wherein the active component A is selected from chromafenozide, and the active component B is selected from any one of the following compounds: lufenuron, ethiprole, chlorfenapyr and pyriproxyfen; and the weight ratio of the active component A to the active component B is (1:70)-(70:1). The composition can prevent various injurious insects, and takes a remarkable synergistic effect; the composition expands an insecticidal spectrum, and shows relatively high activity on rice planthopper, tryporyza incertulas, rice stem borer, rice leaf folder, aphid, tea lesser leafhopper, phthorimaea operculella zell, carpocapsa pomonella, peach fruit moth, lithocolletis ringoniella, olethreutid, leaf miner, phyllocoptruta oleivora ashmead, scale insect, asparagus caterpillar, imported cabbageworm, eumenid poher wasp, thrips, prodenia litura, cotton bollworm and bean-pod borer of crops; and the composition can reduce pesticide consumption, lower pesticide residues on crops and relieve environmental pollution.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition containing cyclafenozide on crop pests. technical background

[0002] Chromafenozide chemical name: 2'-tert-butyl-5-methyl-2'-(3,5-2 toluyl)chromane-6-methylhydrazide, molecular formula: C 24 h 30 N 2 o 3 . Cenfenozide is a dihydrazide insecticide. After being ingested by insects, Cenfenozide inhibits insect feeding within a few hours and causes insects to molt prematurely and lead to death. It interferes with the molt process of insects by regulating the activity of larval hormones and ecdysone , causing premature molt death of insects. Because it can quickly inhibit the feeding of insects, compared with other commonly used 1GR, it can reduce the damage to crops. Cyclofenozide has strong insecticidal activity against noctuids and other caterpillars, regardless of the period; it has low toxicity to mammals, birds, and aquatic orga...

Examples

example 1

[0054] Example 1 71% cyclofenozide·lufenuron wettable powder

[0055] 70% of cyclofenozide, 1% of lufenuron, 6.5% of octylphenol polyoxyethylene ether sulfate, 4% of sapindus powder, and light calcium carbonate were added to 100%, and the mixture was jet-milled to obtain 71 % cyclofenozide lufenuron wettable powder.

[0056] Replacing lufenuron with ethiprole, chlorfenapyr, and pyriproxyfen can also produce new products with the same content and the same dosage form.

example 2

[0057] Example 2 40% cyclofenozide lufenuron wettable powder

[0058] Cyclofenozide 25%, Lufenuron 15%, Polycarboxylate 7%, Sodium Lauryl Sulfate 5%, Kaolin to 100%, the mixture is jet milled to obtain 40% Cyclofenozide·Lice Mifenuron wettable powder.

[0059] Replacing lufenuron with ethiprole, chlorfenapyr, and pyriproxyfen can also produce new products with the same content and the same dosage form.

[0061] Cyclofenozide 1%, Lufenuron 70%, Lignosulfonate 4.5%, Wetting Penetrant F5%, Sodium Bicarbonate 3.1%, Attapulgite to 100%, mixed to get 71% Cyclofenapyr Hydrazine Lufenuron water dispersible granules.

[0062] Replacing lufenuron with ethiprole, chlorfenapyr, and pyriproxyfen can also produce new products with the same content and the same dosage form.
