After the pear tree spreads its leaves, a protective fungicide is sprayed before rain to effectively prevent the infection of the fungus, and it is sprayed with 200 times of 45% sulfur suspension (Qingyuan). In the early stage of pear rust infection, it is best to have lesions appear for 1-5 days, and difenoconazole can be sprayed for control.

Pear dry rot prevention and control methods:

1.Seedlings and young branches should be fertilized reasonably to control the growth of branches. In times of drought, irrigation should be carried out in time.

2.Strengthen cultivation management and enhance tree potential:

Increase fertilizer, prune reasonably, prune diseased and dead branches, irrigate in a timely manner, and pay attention to drainage in low-lying areas.

3.Pharmaceutical prevention and control:

In the seedling growth period, it can be sprayed with 160 times lime multiples Bordeaux solution, or 800 times 50% antibacterial special wettable powder. The seedlings that have been diseased should be scraped off the lesions at the early stage of the disease, and the diseased part should be smeared with Tobuzin ointment, or s-921 antibacterial agent 20 30 times liquid or 2% 401 antibacterial agent. It is also possible to scrape off the lesions without scraping, use a knife to strip the lesions longitudinally, and then apply 20 times of 401 antibacterial agent.
