The tree body sprays and sprays 3~5 Baume degree lime sulfur before the budding of fruit trees to kill most overwintering eggs and pathogens, such as aphids, red spiders, mulberry white pests and powdery mildew, perforation, round Spot, leaf diseases and other pathogens. The bactericides such as carbendazim, thiophanate-methyl, mancozeb, pike, cobo, essential and other bactericides and phoxim, trichlorfon, imidacloprid, annihilation, avermectin can be selected according to the actual conditions after the exhibition. Insecticides such as peony are used alone or in combination. Trunk Use Medicine Control Apply 10 cm wide glue on the base of the trunk or use waste oil or plastic tape to prevent grass worms from harming the insects on the tree. You can also use some of the systemic medicaments to coat the trunk at the base of the trunk or use the trunk automatically. Injection machine for quantitative injection to prevent diseases and insect pests, the drug can be used with buprofezin, thiophanate-methyl, carbendazim and other short-term efficacy, low toxicity, low-residue to the fruit and fruit delivery of low-residue pesticides. Soil medicine control can be used to spray 50% phoxim at the beginning of the larvae excavation, then loosen the soil and loosen the soil, or sprinkle some medicine particles, such as phoxim granules, on the surface soil during the larval incubation period.

To Prevent Fruit Pests and Diseases Early in the Spring
With the gradual increase of temperature, eggs of some pests in spring will be hatched and unearthed in succession, such as locusts, beetles, red spiders, scale insects, etc. will form a peak period of harm, and some diseases will also be harmed in succession, such as rot disease and gum disease. Anthrax, anthracnose, early defoliation, etc. will seriously damage the tree body, causing serious loss to fruit farmers. In order to avoid losses and gain fruit, we must seize the key opportunity in the spring to prevent premature fruit disease.
