Embodiment 1

[0023] A method for preventing and treating black spot of apricot trees, which uses a microcapsule fungicide prepared from a plant source extract as an active ingredient for prevention and treatment, wherein the microcapsule fungicide is prepared from the following raw materials according to mass percentage: plant source 20% of the extract, 20% of prochloraz, 10% of myclobutanil, 9% of Tween-20, 0.6% of sodium lignosulfonate, 0.5% of sorbitan polyethylene polyoxypropylene ether, and the balance is water;

[0024] Prepare microcapsule bactericide according to the following method:

[0025] (1) Preparation of plant-derived extracts: take 15kg of fenugreek, 15kg of aloe, 2kg of clover, 1kg of sophora flavescens, and 2kg of Daphne chamaejasme, and mix them with a plant tissue grinder until they are 1mm to 3mm coarsely crushed. The coarse pulverized material of the method is extracted by water extraction, the extraction temperature is 80° C., and the extraction time is 20 hours to ...

Embodiment 2

[0028] A method for preventing and treating black spot of apricot trees, which uses a microcapsule fungicide prepared from a plant source extract as an active ingredient for prevention and treatment, wherein the microcapsule fungicide is prepared from the following raw materials according to mass percentage: plant source 25% extract, 15% prochloraz, 12% myclobutanil, 4% Tween-20, 0.6% hydroxymethyl cellulose, 0.4% sorbitan monolaurate, and the balance is water;

[0029] The preparation method of described microcapsule bactericide is:

[0030] (1) Preparation of plant-derived extracts: Take 15kg of fennel, 15kg of aloe, 2kg of clover, 1kg of flavescens, and 2-4kg of Daphne chamaejasme, and grind them to a coarse pulverization of 1mm-3mm with a plant tissue grinder, and then mix them. The obtained coarse pulverized product is extracted by water extraction, the extraction temperature is 85° C., and the extraction time is 17 hours to obtain an extract, which is concentrated in vac...

Embodiment 3

[0033] A method for preventing and treating black spot of apricot trees, which uses a microcapsule fungicide prepared from a plant source extract as an active ingredient for prevention and treatment, wherein the microcapsule fungicide is prepared from the following raw materials according to mass percentage: plant source 30% of extract, 10% of prochloraz, 15% of mycloclozan, 5% of Tween-20, 0.6% of polyvinyl alcohol, 0.3% of polypropylene glycol ethylene oxide ether, and the balance is water; In the method for spot disease, in the above-mentioned method for preventing and treating apricot black spot, the stabilizer is sorbitan polyethylene polyoxypropylene ether, sorbitan monolaurate, polypropylene glycol oxyethylene ether, One or more of sodium lauryl sulfate, sodium lauryl sulfate or polyethylene glycol.

[0034] The preparation method of described microcapsule bactericide is:

[0035] (1) Preparation of plant-derived extracts: Take 20kg of fennel, 15kg of aloe, 1kg of clov...

Abstract

The invention discloses an apricot alternaria rot preventing method. The apricot alternaria rot preventing method is implemented through a microcapsule sterilizing agent prepared from botanical extracting solution and conventional sterilizing agent. The microcapsule sterilizing agent is prepared from, by weight percentage, 20-30% of the botanical extracting solution, 10-20% of prochloraz, 10-15% of myclobutanil, 5-9% of tween-20, 0.6-1% of surface active agent, 0.3-0.5% of stabilizer and water as balance. The plant composition in the botanical extracting solution is composed of, by weight part, 15-20 parts of elsholtzia, 10-15 parts of aloe, 1-3 parts of radix tetrastigme, 0.5-1 parts of sophora flavescens and 2-4 parts of stellera chamaejasme. According to the apricot alternaria rot preventing method, the sterilizing agent is made into microcapsules and accordingly can be uniformly mixed with incompatible components to enhance the synergizing effects; meanwhile, the assisting relations among plant materials are comprehensively considered, so that the apricot alternaria rot preventing effects can be obviously improved.

Description

technical field [0001] The invention relates to disease prevention and treatment of apricot trees, in particular to a method for preventing and treating black spot disease of apricot trees. Background technique [0002] Compared with traditional chemical pesticides, botanical pesticides have the advantages of easy availability of raw materials, more action sites, less resistance to pests, easy degradation, low residue, less harm to natural enemies and insects, and environmental safety. Screening highly active substances from natural products, using them as templates to synthesize new chemical pesticides, or directly developing them into natural-source pesticide preparations with high efficiency, low toxicity, low residue, and harmony with the environment has become an important step in the creation of new pesticides. One of the effective ways is the development direction of pesticides in the future. [0003] When the apricot black spot disease occurs, the leaves, petioles, ...
