Abstract

The invention belongs to the field of plant protection, particularly relates to plant essential oil hydrolat for inhibiting and killing plant pathogenic fungi and a preparation method thereof, and solves the problems of antibacterial pesticide residues, complex preparation process, long preparation period and high production cost in the prior art. The plant essential oil hydrolat for inhibiting and killing plant pathogenic fungi comprises the following raw materials in percentage by weight: 5-10% of plant essential oil, 1-3% of a solubilizer, 7-9% of a plant oil emulsifier EL, 50-60% of a solvent, 25-30% of rheum officinale tablets and 0.5-1% of a pH regulator. The production process of the plant essential oil hydrolat for inhibiting and killing plant pathogenic fungi and the preparation method of the plant essential oil hydrolat comprises the following steps: S1, preparing raw materials; S2, preparing a rheum officinale water extract; S3, mixing oil phases; and S4, homogenizing. The prepared plant essential oil hydrolat for inhibiting and killing plant pathogenic fungi is high in cost performance, good in biodegradability, good in stability, non-toxic, short in production cycle and suitable for various production conditions, and it is guaranteed that vegetables can be eaten healthily.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a plant essential oil hydrosol for inhibiting and killing plant pathogenic fungi and a preparation method thereof. Background technique [0002] Every year the whole world is damaged by pests, which reduces grain production by 20% to 40%, and the resulting economic losses amount to 120 billion US dollars. In order to prevent pests and diseases, chemical pesticides have been used in agricultural and forestry production for a long time to control their occurrence and reduce losses in agriculture and forestry. However, chemical pesticides have a series of serious problems such as insurmountable environmental pollution, pesticide poisoning, and pest resistance. According to reports, the annual use of pesticides in my country is 800,000 to 1,000,000 tons, ranking first in the world. In recent years, chemical pesticides account for more than 90% of crops and other pest control. In the ...
