Problems solved by technology

However, immature or germinated potatoes with bruised and purple skin and flesh can easily cause poisoning after eating, such as itchy throat, fever and pain in the chest, nausea, vomiting, etc. These potatoes cannot be guaranteed to be non-toxic even after processing, so most of them are discarded , which causes a waste of resources, and at the same time increases the burden on the surrounding environment

Embodiment 1

[0025] A biological agent for preventing and treating wheat powdery mildew. The raw materials are composed of: 20 parts of potato extract, 3 parts of sodium butyrate, 8 parts of fatty alcohol, 13 parts of polyoxyethylene sorbitan ester, 2 parts of sorbitol, ammonium sulfate 2 parts, 1.0 parts of polyvinyl alcohol;

[0026] The potato extract is extracted by the following method: crush the germinated potatoes with purple skin and flesh, grind them into potato pulp, take 100 parts of the potato pulp, and then add ethanol-ethylene glycol twice the volume of the potato pulp (volume ratio 1:1) , add 0.12 parts of zinc chloride, filter after stirring for 2 hours, and obtain filtrate I; add water to the filter residue, and add 0.8 parts of amylase and a compound enzyme composed of glucoamylase (the mass ratio of amylase and glucoamylase is 1 :0.5), hydrolyze at 38°C for 7 hours, inactivate the enzyme at 120°C, stir for 5 minutes, let it cool to room temperature, add filtrate I and 0....

Embodiment 2

[0032] A biological agent for preventing and treating powdery mildew of wheat. The raw materials are: 26 parts of potato extract, 5 parts of sodium butyrate, 9 parts of fatty alcohol, 15 parts of polyoxyethylene sorbitan ester, 3 parts of sorbitol, ammonium sulfate 2 parts, 0.8 parts of polyvinyl alcohol;

[0033] The potato extract is extracted by the following method: crush the germinated potatoes with purple skin and flesh, grind them into potato pulp, take 100 parts of the potato pulp, and then add ethanol-ethylene glycol twice the volume of the potato pulp (volume ratio 1:1) , add 0.15 parts of zinc chloride, filter after stirring for 2 hours to obtain filtrate I; add water to the filter residue, add 0.65 parts of amylase, glucoamylase compound enzyme (the mass ratio of amylase and glucoamylase is 1 :0.5), hydrolyze at 36°C for 8 hours, inactivate the enzyme at 120°C, stir for 5 minutes, let it cool to room temperature, add filtrate I and 0.1 part of methylisothiazolinone...

Embodiment 3

[0036] A biological agent for preventing and treating wheat powdery mildew. The raw materials are: 30 parts of potato extract, 2 parts of sodium butyrate, 10 parts of fatty alcohol, 10 parts of polyoxyethylene sorbitan ester, 3 parts of sorbitol, ammonium sulfate 1 part, 1.2 parts of polyvinyl alcohol.

[0037] The potato extract is extracted by the following method: crush the germinated potatoes with purple skin and flesh, grind them into potato pulp, take 100 parts of the potato pulp, and then add ethanol-ethylene glycol twice the volume of the potato pulp (volume ratio 1:1) , add 0.14 parts of zinc chloride, filter after stirring for 2 hours, and obtain filtrate I; add water to the filter residue, and add 0.5 parts of amylase and a compound enzyme composed of glucoamylase (the mass ratio of amylase and glucoamylase is 1 :0.5), hydrolyze at 38°C for 8 hours, inactivate the enzyme at 120°C, stir for 5 minutes, let it cool to room temperature, add filtrate I and 0.1 part of me...

Abstract

The invention belongs to the technical field of pesticide preparations and particularly relates to a biological agent for preventing wheat powdery mildew and a preparation method thereof. The biological agent comprises 20-30 parts of potato extracts, 2-5 parts of sodium butyrate, 8-10 parts of fatty alcohol, 10-15 parts of polyoxyethylene sorbitan ester, 2-3 parts of sorbitol, 1-2 parts of ammonium sulfate and 0.8-1.2 parts of polyvinyl alcohol. Resources are recycled by means of sprouted potatoes with cyanotic peel and flesh, waste is turned into wealth, and influences on the environment are reduced. The biological agent prepared through the method is low in residue content, high in wheat powdery mildew cure rate, long in pesticide effect period and beneficial to environment sustainable development, can promote growth of wheat after cure, can prevent pathogenic bacteria from invading from wounds and prevent reinfection of the wounds, and increases yield and income.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a biological agent for preventing and treating wheat powdery mildew and a preparation method thereof. Background technique [0002] Wheat powdery mildew is a common disease of wheat, which can occur during the whole growth period of wheat. In recent years, serious damage has occurred in the Huanghuai wheat region. At present, when the resistance of wheat to powdery mildew is generally poor, pesticide control has become an important means of disease control. In order to combat wheat powdery mildew, azoxystrobin, triadimefon and other pharmaceutical preparations are mainly used at present, but these drugs first aggravate environmental pollution, and secondly, easily cause pesticide residues, and with the enhancement of bacterial resistance, the dosage of drugs Increase, the bacteria are prone to drug resistance, and the duration of effect is short. [0...
