Problems solved by technology

Fungicides have the advantages of high efficiency, quick effect, convenient use, and high economic benefits, but they only have protective effects, no therapeutic and eradicating effects, and the duration of effect is short, and the number of applications is high, and the bacteria have developed resistance to them; long-term unreasonable use Chemical pesticides control strawberry gray mold, causing pathogenic bacteria to gradually develop drug resistance, reducing the control effect, and increasing pesticide residues in fruits, polluting the environment, and increasing production costs
The toxic side effects and residues of chemical pesticides on humans and animals are still difficult to effectively solve

Embodiment 1

[0020] A kind of plant source bactericidal preparation, it comprises the component of following percentage by weight: thymol 2%, emulsifier (emulsifier is phenethylphenol polyoxyethylene ether) 20%, azone 2%, ethanol 40%, water 36%.

[0021] The preparation method of the above-mentioned plant-derived bactericidal preparation, prepare raw materials thymol, emulsifier, azone, ethanol and water according to the formula amount, add thymol to 1 / 4 amount of ethanol and mix uniformly to form solution A, and then emulsifier Dissolve azone and azone with the remaining 3 / 4 amount of ethanol to form solution B, and then mix solution A, solution B and water evenly.

Embodiment 2

[0023] A kind of plant source fungicide preparation, it comprises the component of following percentage by weight: Thymol 1%, emulsifying agent (emulsifying agent is that emulsifying agent is aralkylphenol polyoxyethylene ether phosphoric acid ester and alkylphenol polyoxyethylene ether phosphoric acid ester Esters (1:1 mixture by weight) 10%, azone 2%, ethanol 20%, water 67%.

[0024] The preparation method of the above-mentioned plant-derived bactericidal preparation, prepare raw materials thymol, emulsifier, azone, ethanol and water according to the formula quantity, add thymol to 1 / 2 amount of ethanol and mix uniformly to form solution A, and then emulsifier Dissolve azone and azone with the remaining 1 / 2 amount of ethanol to form solution B, and then mix solution A, solution B and water evenly.

Embodiment 3

Abstract

The invention discloses a botanical fungicide which comprises the following components by weight: 0.1-50% of thymol, 5-30% of emulsifiers, 0.1-20% of azone, 10-60% of ethanol, 0.1-84.8% of water. The invention also discloses a preparation method of the botanical fungicide, and an application in the control of strawberry botrytis cinerea. The medical components of the thymol-based botanical fungicide of the invention are derived from plants or extracts which have an insecticidal function, and the fungicide not only can effectively control crop botrytis cinerea, but also has multiple efficacy of promoting crop growth and development, increasing production and income, improving quality, increasing nutrient utilization rate, controlling insects, causing no pollution, and the like, and is applicable to the production of pollution-free, green, and organic agricultural products. The preparation has significant application effect, easily available raw materials, simple production process, large market potential, obvious economic benefit and social benefit, and has extremely extensive application prospects.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable disease prevention and treatment in agricultural production, and in particular relates to a botanical bactericidal preparation and its application in preventing and treating strawberry gray mold. Background technique [0002] Strawberry gray mold, also known as strawberry rot, is one of the important diseases in current strawberry production. In recent years, with the expansion of strawberry cultivation area, the occurrence and spread of strawberry gray mold has gradually increased, and it has occurred in various strawberry cultivation areas in my country. The pathogen of strawberry gray mold is Botrytis cinerea of ​​the genus Botrytis, which has strong saprophytic properties, wide host range, and slender spores. It can damage leaves, petioles, flower stalks, flowers and fruits respectively, especially during the ripening period of berries. Especially in the peak period of fruit picki...
