After scraping, apply medicine to disinfect the pear trees that have been scraped for 10 seconds. After 15 days, smear the trunk with 50 times bacteriophen or cubiqing solution, disinfect and sterilize. Should pay attention not to scrape bark along with the application of medicine, so as not to cause drug poisoning, resulting in the bad phenomenon of dead branches and dead trees.
