Problems solved by technology

Triazotin is a broad-spectrum acaricide with strong contact effect, which can kill nymphs, adults and summer eggs, but is ineffective against winter eggs
After research by the inventors, it was found that compounding pyrimidan with fenbutatin or triazoltin can produce a good synergistic effect, and the relevant reports about the compounding of pyrimidan with fenbutatin or triazoltin have not yet been published

Abstract

The invention discloses a compound acarid-killing composition containing pyriminostrobin, and in particular relates to an acarid-killing composition containing an active component A and an active component B, wherein the active component A is pyriminostrobin, and the active component B is selected from one of fenbutatin oxide and azacyclotin; the weight ratio of the active component A to the active component B is (1: 80)-(60: 1). The composition disclosed by the invention has a synergism effect on various pest mites harmful to agricultural production; the using amount of pesticides is reduced, the residual amount of the pesticides on the crops is lowered, the environment pollution is alleviated, the compound acarid-killing composition is safe to human and livestock and high in environment compatibility, and pests difficultly have pesticide resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a compound acaricidal composition containing pyrimidamide to crop pest mites. Background technique [0002] Pyrimidan: It is used to prevent and control Panonychus citrus, and the product shows good quick-acting and long-lasting effects under field test measurement. [0003] Fenbutatin oxide (Fenbutatin oxide) chemical name: bis[tri-2-methyl-phenylpropyl) tin] oxide, molecular formula: C 60 h 78 OSn 2 . Phentermine is a non-systemic acaricide, and the harmful mites that are resistant to organophosphorus and organochlorine do not produce cross-resistance to it, and the harmful mites are mainly contact-killed. [0004] Azocyclotin chemical name: 1-(tricyclohexylstannyl)-1-hydrogen-1,2,4-triazole, molecular formula: C 20 h 35 N 3 Sn. Triazotin is a broad-spectrum acaricide with strong contact effect, which can kill nymphs, adults and summer eggs, but is i...
