Problems solved by technology

[0004] In the actual process of agricultural production, pests have a short reproductive cycle, large reproductive capacity, low mobility, and high degree of selfing, and are particularly prone to resistance. For the prevention and control of agriculturally resistant pests, the effective way is to introduce new and There are no new ingredients for cross-resistance in existing varieties; however, the development cost of new active ingredients is high, the development cycle is long, and it will never be able to match the speed of pest resistance. Other methods such as crop layout adjustment and rotation of different pesticides etc., in the process of actual operation, it is difficult to really have an obvious effect;

Embodiment 1

[0032] This embodiment is a preparation method of modified lignin, comprising the following steps:

[0033] S1: Add 10 g of alkali lignin to 150 g of sodium hydroxide solution with a mass fraction of 10%, stir at a stirring rate of 200r / min until the alkali lignin is completely dissolved, filter, and filter the filtrate with a mass fraction of 5% The sulfuric acid solution was adjusted until the pH was 6, centrifuged, and the precipitate was washed with distilled water to neutrality, then placed in a vacuum drying oven, and dried at a temperature of 50°C for 45 hours to obtain refined lignin;

[0034] S2: Add 4g of refined lignin, 100mL of acetic anhydride, pyridine and dioxane at a volume ratio of 1:1:1 into a flask equipped with a stirrer, at a temperature of 50°C and a stirring rate of 200r / Stir and disperse for 1 h under the condition of 1 min, then stop stirring and let stand at constant temperature for 20 h, then cool to room temperature, centrifuge, then add to 300 mL ...

Embodiment 2

[0037] This embodiment is a preparation method of modified lignin, comprising the following steps:

[0038] S1: Add 10g of alkali lignin to 100g of sodium hydroxide solution with a mass fraction of 10%, stir at a stirring rate of 300r / min until the alkali lignin is completely dissolved, and filter the filtrate with a mass fraction of 10%. The sulfuric acid solution was adjusted until the pH was 7, centrifuged, and the precipitate was washed with distilled water to neutrality, then placed in a vacuum drying oven, and dried at a temperature of 55°C for 50 hours to obtain refined lignin;

[0039] S2: Add 4g of refined lignin, 100mL of acetic anhydride, pyridine and dioxane at a volume ratio of 1:1:1 into a flask equipped with a stirrer, at a temperature of 55°C and a stirring rate of 300r / min under the condition of stirring and dispersing for 2h, then stop stirring and let it stand at constant temperature for 30h, then cool to room temperature, centrifuge, then add to 300mL anhy...

Embodiment 3

[0042] This embodiment is a preparation method of a composition containing fluomepyr and chlorfenapyr, comprising the following steps:

[0043] Step 1: dissolving 20g of modified lignin in 200mL of deionized water to obtain an outsourcing solution;

[0044] Step 2: dissolving 1 g of fluomepyr and 19 g of chlorfenapyr in 50 mL of acetone to obtain the inner core solution;

[0045] Step 3: Add the outsourcing liquid and the inner core liquid into a high-speed shearing machine, shear for 5 minutes at a stirring rate of 6000 r / min, add isopropanol, and then stir for 6 hours at a stirring rate of 300 r / min. Afterwards, the composition containing triflumepyr and chlorfenapyr is obtained through evaporation concentration, kneading, extrusion granulation, drying and sieving.

Abstract

The invention discloses a composition containing pyridalyl and chlorfenapyr, and relates to the technical field of pesticide compositions. The pyridalyl and chlorfenapyr serve as main components and are reasonably compounded to generate a good synergistic effect, and a good insecticidal effect can be achieved under the synergistic effect of the pyridalyl and the chlorfenapyr; by adding the modified lignin into the composition, a compound of pyridalyl and chlorfenapyr is loaded or coated to achieve a slow release effect, so that the effective components can act on pests for a long time, the probability that crops are attacked by pests is reduced, and the yield and quality of the crops are improved; lignin is easy to biodegrade and has good environmental protection performance as a carrier, but lignin is still mainly used as a waste of industrial pulping and is directly discharged into a river along with wastewater or is burnt after being concentrated, so that great waste of resources is caused and the environment is polluted, and comprehensive development and utilization of lignin have practical significance on economic development and environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticide compositions, in particular to a composition containing trifluroxyfen and chlorfenapyr. Background technique [0002] Triflumepyr is a novel broad-spectrum insecticide developed in recent years. It is effective against Lepidoptera pests (such as diamondback moth, Spodoptera litura, etc.) and Thysanoptera pests (such as thrips, etc.) on various crops. and Diptera pests (such as Liriomyza sativae, etc.) have shown good control effect; [0003] Chlorfenapyr is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, acts through the multifunctional oxidase in insects, and mainly inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP), and ATP storage cells The energy necessary to maintain its vital functions. The drug has stomach poisoning and contact killing effects, strong permeability on the leaf surface, certain systemic effect, and has...
