[0018] Formula 1: Acetamizuron: 1.0%, chlorpyrifos 24%.

[0019] Formula 2: Acetamizuron: 1.5%, chlorpyrifos 23.5%.

[0020] Formula 3: Acetamizuron: 2.0%, chlorpyrifos 23%.

[0021] Formula 4: Acetamizuron: 2.5%, chlorpyrifos 22.5%.

[0022] Formula five: Acetamizuron: 3.0%, chlorpyrifos 22%.

[0023] Formula 6: Acetamizuron: 1.0%, Quetiafos: 14%.

[0024] Formula 7: Acetamizuron: 1.5%, Quetiafos: 13.5%.

[0025] Formula 8: Acetamizuron: 2.0%, Quetiafos: 13%.

[0026] Formula 9: Acetamizuron: 2.5%, Quetiafos: 12.5%.

Abstract

An agricultural chemical for preventing and eliminating the lepidopterous, elytropterous, hymenopterous, dipterous and thysanopterous pests is prepared from chlorfluazuron and chlorpyrifos or quinalphos through proportionally mixing.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides. Background technique [0002] Acetamizuron is a phenylformyl urea insecticide. It mainly has gastric toxicity to pests, and also has a strong contact effect. It has poor permeability and no systemic effect. It is a chitinase inhibitor of pests, inhibits the formation of chitin, hinders the normal molt of pests, causes egg hatching, molting of larvae, abnormal development of pupae, and adult eclosion and oviposition are hindered to play an insecticidal role. It has high activity against pests, but the action speed is slow, and the larvae will not die soon after contacting the medicine, but the food intake is obviously weakened. [0003] The drug has very high activity against a variety of Lepidoptera pests and some pests of Orthoptera, Coleoptera, Hymenoptera, Diptera, etc., and is a relatively broad-spectrum insecticide. It has a good control effect on pe...
