The Latest Control Methods for Common Diseases and Pests of Bayberry
The bayberry tastes sweet and sour and is bright red on the outside, making people unable to resist eating it as soon as they see it. However, many fruit growers find the invasion of diseases and pests during cultivation a headache. In order to make bayberry bear fruit early and increase yield, disease and pest control work is especially important. Now follow Qinnong Web to take a look at the control methods for common bayberry diseases and pests.
1. Brown spot disease
Brown spot disease mainly harms the leaves of bayberry trees. After a plant is infected with brown spot disease, small purplish-red lesions appear on the leaves. As the disease develops, the lesions gradually expand, causing the leaf edges to become grayish-brown. In the later stage, large brown lesions appear in the center of the spots, and there are also spore masses in the lesions, causing the leaves to wither and fall off. When young trees are severely infected, the disease can lead to death.
Control methods: Strengthen fertilizer and water management, apply more phosphorus and potassium fertilizer, enhance tree vigor, and improve resistance. Pay attention to drainage measures. After the beginning of spring, collect dead branches and fallen leaves on the ground and on the plants, burn or bury them deeply to reduce pathogens. After the disease occurs, spray carbendazim for control.
2. Crown gall disease
As the name suggests, crown gall disease is like a tumor in the human body. After a plant is infected with this disease, there are protruding milky-white small spots on the branches, and the surface of the protrusions is smooth, generally appearing at the nodes. As the disease develops, the protruding spots become larger and larger, eventually causing the branches above the tumor to die because they cannot obtain nutrients, and the bark of the plant also dries and cracks, often causing premature aging of the plant until death.
Control methods: Do a good job in protecting plants and avoid wounds on plants, whether caused by humans or animals, to reduce the possibility of pathogen infection. Apply more organic fertilizer and phosphorus and potassium fertilizer to enhance tree vigor and improve resistance. After discovering the disease, cut off the tumor site, spray disinfectant on the wound, and burn the removed part to prevent secondary infection.
3. Root rot
Root rot mainly harms the plant root system. It is caused by infection by pathogens in the soil. The pathogens invade the plant root system and hinder the normal growth of the roots. It is not easy to notice in the early stage, and it shows as leaf discoloration and falling off, poor plant growth, and relatively weak vigor. In severe cases, it causes root rot and plant death.
Control methods: Deeply plow and disinfect the soil to reduce soil pathogens. Disinfect the roots when planting to avoid introducing pathogens. Strengthen management, apply more phosphorus and potassium fertilizer, and improve disease resistance. After discovering diseased plants, pull them out and burn them in time to prevent the spread of pathogens, then disinfect the planting holes.
4. Insect pests
Bayberry has many insect pests, such as the common pine caterpillar, bagworm, and leaf roller moth. They all like to feed on tender leaves or leaf tips, eating all the tender leaves and leaf tips, causing poor plant growth, and in severe cases the plants die.
Control methods: At night, light traps can be used to trap and kill them, or insecticides can be sprayed for control.
