Bayberry tastes sweet and sour, and its appearance is bright red. People can't help eating it when they see it. However, many fruit growers encounter pests and diseases when planting, which is a headache. In order to make bayberry early fruit, improve yield, pest control work is particularly important, the following with the parent farming network to see the common pest control methods of bayberry bar.

1. Brown spot disease

Brown spot mainly damages the leaves of Myrica rubra. After the plant is infected with brown spot, the leaves appear small purple spots. With the development of disease, the spots gradually expand, resulting in gray brown at the edge of the leaves. In the late stage, large brown spots appear in the center of the spots. There are spores in the spots, resulting in leaf withering and falling. Young trees infected with the disease can lead to death.

Control methods: strengthen fertilizer and water management, increase phosphorus and potassium fertilizer, strengthen tree vigor, improve resistance, pay attention to drainage measures, introduce concentrated collection of dead branches and leaves on the ground and plants after spring, burn or bury deeply, reduce pathogens, spray carbendazim after disease.

2. Cancer

Cancer disease listen to the name know, it is like our human body tumor, plant infection in the disease, branches have prominent milky white dots, prominent smooth surface, generally in the branch site attack. As the disease progresses, the protruding point becomes larger and larger, and finally the branches above the tumor should not get nutrients and die, while the bark of the plant will also dry and crack, often causing premature aging of the plant until death.

Prevention and control methods: do a good job of plant protection, avoid plant wounds, whether it is thought or animals, can reduce the possibility of bacterial infection, increase the application of organic fertilizer and phosphorus and potassium fertilizer, enhance tree vigor and improve resistance, after the disease is found, the tumor part will be removed, spray disinfectant on the wound, burn the removed part, prevent secondary infection.

3. Root rot

Root rot is mainly harmful to plant roots. It is caused by pathogen infection in soil. The pathogen invades the root system of the plant and hinders the normal growth of the root system. It is not easy to detect in the early stage. It is realized as leaf discoloration and shedding. The plant grows poorly. It is weak. When it is serious, it leads to root rot and plant death.

Control method: the plant will be deeply turned soil disinfection, reduce soil pathogens, planting root disinfection, so as to avoid the introduction of bacteria, strengthen management, increase phosphorus and potassium fertilizer, improve disease resistance, found sick plants, timely uproot burned, so as to avoid the spread of bacteria, and then disinfection treatment of planting holes.

4. Insect pests

Myrica rubra has many pests, such as pine caterpillar, debt-avoiding insect and leaf roller moth. They all like to eat young leaves or leaves, resulting in poor growth of plants, and serious planting will die.

Prevention and control methods: light can be used at night trap, or spray insecticide control.
