Embodiment 1

[0026] A botanical insecticide for preventing and controlling crop pests, the active ingredient of which has a structural formula of

[0027] of nicotine citrate.

[0028] In this example, 5% of the active ingredient of nicotine citrate was weighed, 3% of solvent ethanol was added, 2.5% of emulsifier polyoxyethylene sorbitan fatty acid ester, 1.5% of fatty alcohol polyoxyethylene ether, and cosolvent B Glycol 2%, stir until the emulsifier dissolves and mix with other ingredients evenly; finally add deionized water to make up 100%, stir for 10min-20min and mix evenly to obtain 5% nicotine citrate soluble agent.

[0029] The preparation method of nicotine citrate is a preparation method known in the art, and will not be repeated here.

Embodiment 2

[0031] A botanical insecticide for preventing and controlling crop pests, the active ingredient of which has a structural formula of

[0032] of nicotine citrate.

[0033] In this example, 5% of the active ingredient of nicotine citrate was weighed, 3% of the emulsifier fatty alcohol polyoxyethylene ether, 1% of the polyethylene oxide block copolymer, 4% of the solvent cyclohexanone, and a cosolvent 2% polyethylene glycol, stir until the emulsifier dissolves and mix with other ingredients evenly, add deionized water to make up 100%, stir for 10min-20min and mix evenly to obtain 5% nicotine citrate microemulsion.

Embodiment 3

[0035] A botanical insecticide for preventing and controlling crop pests, the active ingredient of which has a structural formula of

[0036] of nicotine citrate.

[0037] In this example, 10% of the active ingredient of nicotine citrate was weighed, 1% of calcium dodecylbenzenesulfonate as an emulsifier, 3.5% of styrene ethylphenol polyoxyethylene ether, polyethylene oxide block copolymer 1.5%, add 4% ethyl oleate, solvent oil to make up 100%, stir for 10min-20min and mix evenly to get 10% nicotine citrate emulsifiable concentrate.

Abstract

The invention discloses a botanical insecticide for preventing and treating crop pests. The botanical insecticide comprises the following effective components: nicotine citrate. The botanical insecticide has high biological activity on most piercing-sucking mouthpart pests, and can be used for development and application of biological insecticides for effectively preventing and controlling crop pests.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, in particular to a botanical insecticide for controlling crop pests. Background technique [0002] Botanical pesticides refer to pesticides whose active ingredients are derived from plants. Often classified together with microbial pesticides or biochemical pesticides as biopesticides or pesticides of biological origin. As the public's health awareness and environmental awareness continue to increase, chemical pesticides have brought many negative effects on agricultural production due to environmental pollution and high residues. Biopesticides have the advantages of easy degradation in the environment, safety to humans and animals, and strong selectivity, which meet the requirements of sustainable development of green agriculture. [0003] Nicotine is derived from the Nicotiana plant of the Solanaceae family and is the main alkaloid of tobacco. The average content of nicotine in tobacco ...
