Pears in winter to prevent pests

Answer: Pyrospharus sinensis should be controlled to scrape the old rough skins on the trunks and stems before germination in early spring, and collect and burn the scurfs. Pear borers, which can be combined with winter cuts of fruit trees, cut off shoots with buds, or examine tree buds in early spring for early removal. The pear caterpillars, in the early spring, scrape off the rough skin and cracks on the branches and collect and burn them. The young garden can exterminate the insects around the dry base.
