Pesticide composition containing nitenpyram

Abstract

The invention discloses a nitenpyram composition which comprises the following ingredients by weight: 0.1 to 90 percent of nitenpyram, 0.1 to 90 percent of bifenthrin, 0.1 to 90 percent of high-efficiency Lambda-cyhalothrin, 0.1 to 90 percent of banleptm, 0.1 to 90 percent of hexaflumuron, 0.1 to 90 percent of isoprocorb and balance solvent or auxiliary agent useable and acceptable in pesticide. The nitenpyram composition has a plurality of pesticide theories, is provided with nerve poison so as to have optimal contact poisoning effect, stomach poisoning action and osmotic effect, has obvious synergized action, widens the insecticidal spectrum and insects are not easily resistant to the nitenpyram composition.

Description

technical field

[0001] The invention relates to a nitenpyram composition, in particular to a crop insecticide compounded by nitenpyram and several insecticides. Background technique

[0002] Nitenpyram, neonicotinoid insecticide, chemical name is (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2-nitroso Ethyldiamine, pure product is light yellow crystal, melting point 83-84°C, density 1.40 (26°C), vapor pressure 1.1×10-9Pa (25°C), solubility (g / L, 20°C): water (pH =7) 840, chloroform 700, acetone 290, xylene 4.5. It mainly acts on the nerves of insects, similar to other neonicotinoid compounds, and is mainly used to control rice, vegetables and other insects with piercing and sucking mouthparts.

[0003] In addition, pyrethroid pesticides have the advantages of strong toxicity, less dosage, wide insecticidal spectrum, low residue, and safe use. However, after single and continuous use in a large area, pests develop resistance to pyrethroid pesticides, and the developme...
