[0031] The preparation method of the natural fungicide for peach gum disease in the Examples and Comparative Examples includes the following steps in sequence:

[0032] (1) The raw materials are crushed, sieved, and mixed to obtain a mixture;

[0033] (2) Add 7 times the amount of water to the mixture, heat to 100°C and cook for 3 hours;

[0034] (3) Filter, collect the filtrate, add 7 times the amount of 95% ethanol aqueous solution to the filter residue, heat to 60°C and cook for 2-4 hours;

[0035] (4) Filter, combine the filtrate, and concentrate the filtrate until there is no alcohol, which is a natural fungicide for peach gum disease.

[0036] Mix the above-mentioned natural fungicide for peach gum disease with 500 times the weight of water to form the fungicide. Put it into the sprayer, and spray it once a week from the beginning of spring to one month before picking the peaches. The spray amount is 1.5L, sprayed at 5 o'clock in the afternoon every day.

[0037] Test (1):

[0038] The natural fungicides for peach gum disease obtained in Examples 1-10 and Comparative Examples 1-2 were tested on the same peach orchard. 130 adult cherry trees were randomly selected, and all of them had one fruit, and they were randomly divided into 13 Group, the test group was treated with the methods of Examples 1-10 and Comparative Examples 1-2, the control group was not sprayed with fungicides, and the rest of the planting conditions were the same as the test group. The test results are shown in Table 3.
