There are three tricks to eliminate pests in orchards.
Scrape bark in the rough skin, cracks and cracks in fruit trees, often hidden in the pit apple borer, apple leaf roller moth, date tapeworm, pear caterpillar and other pests. Before the budding of the fruit trees in spring, the rough skin on the branches (especially in the tree branches) and the scalp kerfs are completely scraped off, and a large number of overwintering pests can be eliminated. It is advisable to scrape off the light-brown skin and see the green is not white. When scraping the skin, lay a plastic sheet under the tree to collect the scraped bark and debris and concentrate it deeply or burn it. For fruit trees with rot and blight, apply lime sulfur after scraping.
Shaving the tree tray The spring shaving tree tray is not only an important measure to improve the soil and promote the production of fruit trees, but also an effective method to eliminate overwintering pests. Through deep plowing, pests (such as peach borer, peach aphid, etc.) and pathogens that overwinter in the soil can be turned to the surface and frozen to death, dried or eaten by natural enemies, causing some litter on the ground and weeds. The bacteria and pests in the middle of winter were suffocated when they were buried underground.
Before the overwintering larvae are unearthed, the overlying mulch film is glued into a piece according to the size of the crown projection. Cut a seam from the side to the midpoint, pull the shearing seam from the trunk and place it under the crown, and the rim of the mulching film is buried underground. About 20 centimeters, with the trunk contact with string tight, filming time lasted until early September, to reduce the red spider, peach borer pests and other harmful effects of tree damage significantly.
