Abstract

The invention discloses insecticidal composition containing pymetrozine and dinotefuran. The insecticidal composition is prepared from raw materials in percentage by weight as follows: 11%-19% of pymetrozine, 6%-9% of dinotefuran, 1%-5% of methylisothiazolinone, 1%-2% of garlic oil, 0.1%-0.25% of wood vinegar, 0.1%-2% of an accelerator, 4%-15% of a dispersant, 2%-6% of a wetting agent, 5%-15% of a disintegrant and the balance of filler. A preparation method of the insecticidal composition containing pymetrozine and dinotefuran comprises mixing and crushing, superfine grinding, kneading and granulation/tableting. The invention further discloses an application of the insecticidal composition. The insecticidal composition has no dust damage during usage, is convenient to package and transport, contains no organic solvents, has no flammability and phytotoxicity problems and enriches the dosage forms of existing insecticidal active ingredients. The insecticidal composition has the characteristics of being environment-friendly, good in effect, resistant to rain wash, long in lasting period and safe to crops and shows the good control effect on pests with piercing-sucking mouthparts.

Description

technical field [0001] The invention relates to an agricultural insecticidal composition, in particular to an insecticidal composition containing pymetrozine and dinotefuran, a preparation method and application thereof. Background technique [0002] Pymetrozine belongs to pyridine or triazinone insecticides. It is a relatively novel non-biocide agent. It has excellent control effects on piercing and sucking mouthparts pests of various crops, and has contact and systemic effects on pests. active. The agent can be transported in both xylem and phloem in plants, so it can be used for both foliar spray and soil treatment. Because of its good conduction properties, it can also effectively protect the newly grown branches and leaves after the stems and leaves are sprayed. [0003] Dinotefuran is a third-generation neonicotinoid insecticide developed by Japan's Mitsui Chemicals in 1993 and introduced to the market in 2002, but it has not yet been widely used in China. Its chemi...
