Abstract

The invention discloses grain storage insecticide containing spinosad, a preparation method and application thereof. The grain storage insecticide containing spinosad comprises the following components in parts by weight: 40 to 50 parts of dichloroethane, 6 to 10 parts of methyl formate, 4 to 8 parts of methyl bromide, 10 to 15 parts of spinosad, 10 to 20 parts of an emulsifier, 6 to 12 parts of amicroemulsion and 15 to 20 parts of an organic solvent. The preparation method of the grain storage insecticide containing spinosad is characterized by comprising the following steps: step one, adding the spinosad in the above mass fraction into the organic solvent in the above mass fraction in batches for sufficient stirring, heating to a certain temperature so that the spinosad is completely dissolved into the organic solvent to obtain a mixed solution I; step two, adding the dichloroethane in the above mass fraction, the emulsifier in the above mass fraction and the methyl formate in the above mass fraction into the mixed solution I, and stirring uniformly to obtain a mixed solution II; and step three, dropwise adding the methyl bromide in the above mass fraction into the mixed solution II, and stirring to obtain the fumigation insecticide.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a stored grain insecticide containing spinosyn and its preparation method and application. Background technique [0002] Storage pests refer to pests that live in warehouses, processing plants and other places, and endanger various animal and plant storage materials, warehouses, factory buildings, packaging equipment, storage and transportation tools and equipment. Grain storage pests are the most important part of storage pests affecting humans. [0003] The control methods of grain storage pests can be roughly divided into physical insecticide and chemical insecticide. [0004] (1) Physical insecticide. Including low temperature insecticide, controlled atmosphere insecticide, ozone insecticide, irradiation, microwave, radio frequency insecticide, etc. The first three physical insecticide methods have high requirements on the environment, equipment or air tightness, and relatively...
