Problems solved by technology

Chemical control works quickly and has obvious control effects, and can effectively control the spread of diseases in a short period of time. However, Botrytis cinerea reproduces quickly, has large genetic variation, and has strong adaptability. Botrytis cinerea can easily develop resistance to commonly used fungicides, even multi-drug resistance
At present, there is a lack of a kind of gray mold fungicide that is green and environmentally friendly and has good bactericidal effect

Embodiment 1

[0036] 200 g of livestock and poultry excrement (blister) and 200 mL of water were placed in a high temperature and high pressure reactor in a ratio of 1 g / 1 mL, heated to 230 ° C, pressure of 5.2 MPa, and heated for 2 h, stop heating, natural cooling, cooling to After room temperature, the solid-liquid mixture was removed, filtered with vacuum pump, and the pressure was 0.1 MPa, and the filtration solution was collected, and the fungicide was obtained, and the spare was stored at 4 ° C.

Embodiment 2

[0038] 100g of corn stalk and 100 g of livestock excrement and 250 ml of water were added to 210 ° C, which was heated to 210 ° C, pressure of 3.5 MPa, which was used for 5 h, and naturally cooled after heating. After cooling to room temperature, the solid-liquid mixture was removed, filtered with vacuum pump, and the pressure was 0.1 MPa, and the filtration liquid was collected, and the fungicide was obtained, and the spare was stored at 4 ° C.

Embodiment 3

[0040]The 20g of corn straw 80g livestock excrement and 100 ml of water were placed in a 1 L high-temperature high-pressure reactor in a ratio of 1: 4: 5, heated to 250 ° C, the pressure was 6.8 MPa, and the heated was 20 h, and naturally cooled naturally after stopping heating. After cooling to room temperature, the solid-liquid mixture was removed, filtered with vacuum pump, and the pressure was 0.1 MPa, and the filtration liquid was collected, and the fungicide was obtained, and the spare was stored at 4 ° C.

Abstract

The invention provides a method for preparing a bactericide for inhibiting botrytis cinerea and application, and belongs to the technical field of plant disease control. The method comprises the following steps: carrying out high-temperature and high-pressure liquefaction on agricultural and / or animal husbandry wastes in a high-temperature and high-pressure reaction kettle, carrying out solid-liquid separation after cooling and composting, and collecting a liquid component to obtain the bactericide. The method provided by the invention is simple to operate, does not need any chemical reagent except water, can quickly treat a large amount of agricultural and / or animal husbandry wastes, realizes resource recycling, conforms to the environmental protection concept, solves the pollution problem of the existing agricultural and / or animal husbandry waste resources, and also solves the problems of high toxicity and low cost of a bactericide. And more residues are generated. The botrytis cinerea inhibiting bactericide prepared by the method can effectively inhibit botrytis cinerea.

Description

Technical field [0001] The present invention belongs to the field of plant disease prevention and treatment, and in particular, the present invention relates to a method and application of the preparation of fungicides inhibiting gray. Background technique [0002] The botrytis cinerea is slender, which has a gray black, a irregular tree branch, which grows on the top of the spherical branch. There are many stems, and the stem grows with spores, spores. Colorless, elliptical or oval, aggregation growth is grayed, exterior like spiker berries, and thus also referred to as gray grapes. The host of Gray Mill is very wide, which can infringe on the tomato and other eggtes of fruits and vegetables, grapes, strawberries and other berry fruits, as well as plant varieties such as flowers, crops. my country's gray mold prevention and treatment is the main means of chemical prevention and treatment, and chemical control is the simplest way to prevent plants from infertility and inhibit the...
