Abstract

The invention discloses a method for preparing and using a medicament for treating apple tree rot. The preparation raw materials of the medicament include wood tar stock solution, Tween or ethanol, and distilled water, wherein the wood tar stock solution, Tween and distilled water are according to a:b:(a+ The volume ratio of b) is used to prepare pharmaceuticals, where a and b must meet a≤b≤4a; or the volume ratio of ethanol, distilled water and wood tar stock solution is 15c:c:d to prepare pharmaceuticals, where c and d must meet 16c ≤d≤64c. Use the prepared medicine according to the following method. First, scrape off the branches and trunks that are guilty of rot, and then use a sterilized knife to continue scraping the branches around the disease spots. Finally, from January to February every year, From March to April and July, use a brush to apply the medicine to the scraped lesions. The medicament is simple to prepare, convenient to use, low in cost, and less polluting to the environment. In addition, after a large number of tests, the prepared medicament has a better effect of treating apple tree rot disease according to the prescribed use method.

Description

technical field [0001] The invention relates to a preparation method and a use method of a medicament for treating fungal parasitic diseases of fruit trees, in particular to a preparation method and a use method of a medicament for treating apple tree rot. Background technique [0002] Apple trees are deciduous trees, and the branches of wild apple trees can be as high as 15 meters. In order to facilitate the agronomic management of apple trees, artificially cultivated apple trees are generally only 3 to 5 meters high. degree of shedding. Its fruit is generally red, and the fruit is rich in minerals and vitamins, and is one of the most commonly eaten fruits for people. [0003] Apple trees are mainly distributed in Liaoning, Hebei, Shanxi, Shandong, Shaanxi, Gansu, Sichuan, Yunnan, Tibet and other places in China. According to the data released by the National Bureau of Statistics in 2012, my country's apple tree planting area is as high as 2.231 million hectares, accounti...
