Scraped bark In the rough bark, warped bark and cracks of fruit trees, there are often many kinds of pests lurking, such as pear heartworm, apple leaf roller moth, jujube armyworm, and pear star caterpillar. Before the fruit trees sprout in early spring, thoroughly scrape off the rough bark on the branches (especially the branches) and cut the cuts and warp bark. It is advisable to scrape off the light brown skin to see green but not white; when scraping, spread a piece of plastic sheet under the tree to collect the scraped bark and debris, and bury it in a concentrated way or burn it. For fruit trees with rot disease and dry blight, after scraping their skins, they should be protected by the general tree guard.
Tree planing plate in early spring is not only an important measure to improve the soil and increase the production of fruit trees, but also an effective method to eliminate overwintering pests. After deep planing, you can choose to use Genshitong and fungicide for watering, which can promote the effective ingredients of pesticides to kill the root pests of fruit trees.
