preparation example Construction

[0030] The invention provides the preparation method of the functional preparation, comprising the following steps: 1) dissolving potassium dihydrogen phosphate and dimethyl hydrogen phosphate trihydrate with water to obtain a salt solution; 2) dissolving the epigallocatechin gallate and ascorbic acid are mixed with the saline solution, and the volume is constant to obtain a functional preparation.

[0031] In the specific implementation process of the present invention, it is preferred to mix the potassium dihydrogen phosphate, dimethyl hydrogen phosphate trihydrate and part of the water for dissolution, then mix the epigallocatechin gallate and ascorbic acid with the saline solution, Volume. In the present invention, the constant volume is preferably performed with water; the sum of the water for dissolving potassium dihydrogen phosphate and dimethyl hydrogen phosphate trihydrate and the water used for constant volume is the amount of water in the functional preparation.

Embodiment 1

[0035] The components and contents of the functional preparation in this embodiment are as follows, and each 100mL preparation contains:

[0036]

[0037] Prepare the preparation according to the above proportions, first dissolve potassium dihydrogen phosphate and dipotassium hydrogen phosphate trihydrate in water and mix evenly, then pour epigallocatechin gallate and ascorbic acid into the mixture, and finally add Add the remaining water to 100mL and mix evenly.

[0038] Take 100mL of the preparation, add 15L of water, mix well, and spray on the surface of strawberry leaves or fruits. Spraying began on January 15 of that year, spraying once every other day, and spraying 5 times in total. The test results are shown in Table 1. The application of this preparation can effectively alleviate the occurrence of gray mold of strawberries. Compared with the control without application of the preparation of the present invention, the incidence of gray mold of strawberries using the...

Abstract

The invention provides a functional preparation for improving resistance to gray mold of strawberry and its preparation method and application, which belong to the technical field of strawberry disease prevention and control. The functional preparation uses epigallocatechin gallate as an active ingredient; The mass percent content of epigallocatechin gallate in the functional preparation is 0.5%-1.2%. The functional preparation provided by the invention is convenient to use, has low cost, can effectively prevent and treat strawberry gray mold, and is widely used in strawberry production.

Description

technical field [0001] The invention belongs to the technical field of strawberry disease prevention and control, and in particular relates to a functional preparation for improving the resistance of strawberry botrytis and its preparation method and application. Background technique [0002] Botrytis cinerea is an important disease in strawberry production, especially in greenhouse-cultivated strawberries. Strawberry gray mold mainly affects leaves, flowers and fruits. When the fruit is diseased, it will seriously affect the quality of strawberries and cause great losses to strawberry production. Since strawberries are generally eaten fresh, the requirements for pesticide residues in strawberry production are also very strict. At present, chemical pesticides are mainly used in production to control strawberry gray mold. Due to continuous use for many years, the resistance of gray mold bacteria to pesticides has been accelerated, resulting in unsatisfactory control effects...
