How to prevent and control peach brown rot? Introduction to practical methods
Control methods for peach brown rot
Teacher Cai, my family grows about a hundred mu of peach trees, and every year we lose tens of thousands of jin because of rotten peaches. We have never been able to solve this problem. I have looked up quite a lot of information, but those methods were not effective. Please help me solve it.

Answer: Comrade Zou Long:
Hello. According to a report in the Jiangsu Agricultural Science and Technology News, in order to find effective fungicides for this disease (peach brown rot), Chen Xiuhui and others from the Fruit and Tea Technology Center of Linyi City, Shandong Province, conducted field trials in 2007 using Bayer CropScience Germany's Horizon (43% tebuconazole suspension concentrate) and Antracol (70% propineb wettable powder).
The trial results showed that both Horizon and Antracol have good control efficacy against peach brown rot. The control efficacy of Antracol at 600 times dilution exceeded 91%, with a residual effect period of about 15 days; the control efficacy of Horizon at 5000 times dilution was stable at about 90%. Both of these agents can be promoted for use in the control of peach brown rot. In addition, Antracol's zinc supplementation effect is relatively obvious. After application, the leaves are darker in color and thicker, and the fruit has good gloss. Compared with mancozeb, Antracol has a higher zinc content, and the complexed zinc it contains is more easily absorbed and utilized by fruit trees. At the same time, it can avoid the "manganese toxicity" such as rough bark, black spots, and premature aging in fruit trees induced by long-term use of mancozeb-type fungicides.
Propineb is a protective fungicide, and its mechanism of action is to inhibit the oxidation of pyruvic acid in the pathogen. Tebuconazole mainly exerts fungicidal activity by inhibiting the demethylation of sterols in fungi, which blocks the formation of biological membranes. It can be absorbed through leaf penetration and conducted and evenly distributed within the plant. It has protective, therapeutic, and eradicative effects and is a broad-spectrum systemic fungicide. In the trials, it was found that reducing the dosage and mixing the protective Antracol with the systemic Horizon has strong complementarity, can significantly improve the control efficacy against peach brown rot, and does not increase the cost of medication. The mixed combination of Horizon (10000 times dilution) plus Antracol (1000 times dilution) had an average control efficacy of 94.26%, which was 3.3% higher than the average control efficacy of Antracol alone at 600 times dilution and 5% higher than the average control efficacy of Horizon alone at 5000 times dilution. In the control of peach tree diseases, Antracol and Horizon can be reasonably mixed for use.
