Embodiment 1

[0030] (1) Extraction of solvent-based lignin (DES lignin):

[0031] Poplar is subjected to steam flash explosion treatment: 1 kg of poplar is placed in a plastic bag and impregnated with a mass fraction of 0.7wt% (based on dry wood weight) dilute sulfuric acid solution, the solid-to-liquid ratio is 1:1, and placed overnight at room temperature . The impregnated poplar samples were then transferred into a 2-L cooking tank, and after steam flash explosion, the resulting slurry was collected and filtered, and the solid part was washed with 1 L of water and stored at 4 °C for future use.

[0032] DES pretreatment: put poplar treated with steam flash explosion and DES into the Erlenmeyer flask at a mass ratio of 1:20, and continuously stir and heat at 130°C for 3h, cool the reaction mixture to about 80°C, and then add 30mL of acetone / water mixture (volume ratio 50 / 50) to reduce its viscosity, filter, in order to remove residual choline chloride deep eutectic solvent and lignin in...

Embodiment 2

[0040] Abamectin consumption is adjusted to 30g in embodiment 1 step (3), and other operation steps are identical with embodiment 1.

Embodiment 3

[0042] In embodiment 1 step (3), the solvent-type lignin consumption is adjusted to 30g, the water-insoluble xylan consumption is adjusted to 30g, and the avermectin consumption is adjusted to 20g, and other operation steps are the same as in embodiment 1.

Abstract

The invention discloses an enzyme-responsive controlled-release insecticide, its suspending agent and a preparation method thereof. The enzyme-responsive controlled-release insecticide has a core-shell structure, and is composed of an enzyme-responsive lignin-xylan nanocomposite microparticle The ball is the wall material, and the insecticide embedded in the wall material is the core material; wherein, the insecticide is a hydrophobic insecticide; the enzyme-responsive lignin-xylan nanocomposite microsphere is selected from The xylan is water-insoluble xylan, and the selected lignin is solvent lignin. The controlled-release insecticide of the present invention can use xylanase to hydrolyze and control the release of the insecticide, thereby realizing the controlled release of the insecticide on the surface of crops, prolonging the action time of the insecticide and improving the utilization rate of the insecticide.

Description

technical field [0001] The invention relates to an insecticide, in particular to an enzyme-responsive controlled-release insecticide, a suspending agent and a preparation method thereof. Background technique [0002] Pesticides are an important agricultural input to increase crop productivity and prevent major biological hazards. However, in actual use, more than 90% of pesticides will flow into the environment, which not only reduces the utilization rate of pesticides, but also causes agricultural non-point source pollution, and excessive pesticide residues also threaten food safety. The active ingredients of pesticides are mostly water-insoluble organic compounds, which need to be processed into a suitable formula together with auxiliary ingredients such as carriers, solvents, emulsifiers, and dispersants to facilitate spraying. In order to improve the dispersibility of traditional pesticide preparations, a large amount of organic solvents are used, which further causes e...
