Control methods of Peach Brown Rot

Teacher Cai has planted more than 100 mu of peach trees in my family. Tens of thousands of jin of peach fruits are lost every year, which has not been able to solve this problem. I have checked a lot of information, but those methods are not effective. Please help me solve them.

A: comrade Zou long: Hello, according to the Jiangsu Agricultural Science and Technology Daily, in order to find an effective fungicide for the disease (peach brown rot), Chen Xiuhui, Fruit Tea Technical Center of Linyi City, Shandong Province, and others selected Haolek (43% tebuconazole suspension) and Antaisheng (70% Bingsen zinc wettable powder) of Germany Bayer crop Science Company in 2007. The results showed that both Haolike and Antaisheng had good control effect on peach brown rot. The control effect of Antaisheng liquid was more than 91% and lasted for about 15 days. The control effect of 5000 times solution was stable at about 90%. Both of these two pesticides can be widely used in the control of peach brown rot. In addition, the zinc supplement effect of Antaisheng was more obvious, the leaves were dark and thick, and the fruit glossiness was good. Compared with mancozeb, Antaisheng has a higher content of zinc, and its complex zinc is easier to be absorbed and utilized by fruit trees. at the same time, it can avoid manganism caused by long-term use of mancozeb fungicides, such as coarse bark, black spots, premature senility and so on. Promethazine is a protective fungicide, and its mechanism is to inhibit the oxidation of pyruvate in bacteria. Tebuconazole mainly inhibits the demethylation of sterols in fungi, which hinders the formation of biofilm and leads to volatilization and bactericidal activity. Tebuconazole can be permeated and absorbed through leaves and transmitted and evenly distributed in the body. Tebuconazole has the effect of protection, treatment and eradication. It is a broad-spectrum internal absorption fungicide. In the experiment, it was found that the mixed use of Antaisheng and Halik with internal absorption could significantly improve the control effect of peach brown rot without increasing the cost of medication. The average control effect of the mixture of Halik (10000 times solution) and Antaisheng (1000 times solution) was 94.26%, 3.3% higher than that of Antaisheng solution alone and 5% higher than that of 5000 times solution alone. Antaisheng and Haolike can be mixed in peach tree disease control. The above is for reference only.
