What pesticides does Waxberry use?

When it comes to bayberry, everyone must be familiar with it. It not only has high nutritional value, but also tastes sweet and is very popular with people. At present, it is grown in most areas. What kind of pesticide does Waxberry use?

1. Brown spot

Damage symptoms: needle-sized purplish red dots appear on the surface of the leaves infected with brown spot. With the deepening of the disease, the edges of the leaves gradually show brown or grayish brown. In the later stage of the disease, the center of the spot becomes light reddish brown or grayish white, and there are sporangium spores scattered above. The diseased leaves finally dried up and fell off.

Prevention and control methods: apply more organic fertilizer and potash fertilizer to enhance the resistance of trees and eliminate stagnant water in tree plates in time; remove withered branches and leaves in the garden in early spring to reduce pathogenic branches; if you have been infected with bacteria, you can spray 1000 times diluted carbendazim.

2. Cancer disease

Damage symptoms: the branches infected with bayberry cancer will produce milky protuberances with smooth surface, which usually occur in the branches, which will cause the parts above the tumor to die; the bark is rough and cracked, convex and uneven, which will cause premature senescence of the trees. in severe cases, it will cause the death of the whole plant.

Prevention and control methods: pay attention to protect the tree, reduce the wound on the tree as much as possible, try to avoid causing mechanical damage to the tree, prevent bacteria from invading and infection; increase the application of organic fertilizer and potash fertilizer to enhance the resistance of the tree.

3. Root rot

Symptoms of damage: bacteria generally invade from the wound, hyphae invade the vascular bundle, resulting in browning and necrosis, and in serious cases, lead to the growth and decay of the whole tree. The leaves are light green (withered), gradually turn reddish brown and fall off, leaving a few branches and leaves, but can not sprout and grow the following year.

Control methods: deep ploughing to improve soil, increase the application of organic fertilizer and potassium fertilizer, can improve disease resistance; timely dig and burn diseased plants to avoid further spread; pay attention to red bayberry should not be mixed with peaches, pears, plums and other trees.

4. Pine caterpillar

Damage symptoms: pine caterpillar can harm a variety of trees, newly hatched larvae like to gather on the new shoots and tender leaves, but the ability to spread is very strong, easy to cause scattered food damage, serious leaves only leaves veins.

Control methods: the newly hatched larvae should be killed in time and sprayed with 100 times diluted trichlorfon solution; the adults have strong phototaxis and can be trapped and killed by light.

5. Debt evaders

Damage symptoms: debt avoidance insects mainly harm the new shoots and twigs of red bayberry, which will crush the leaves and lead to the death of buds and twigs.

Control methods: the newly hatched larvae should be killed in time and sprayed with 100 times diluted trichlorfon solution.

6. Leaf roll moth

Damage symptoms: leaf roll moth larvae like to spin silk and wrap leaves on the new shoots and tender leaves of red bayberry, causing the leaves to curl and wrap their larvae in the leaves, and then the larvae eat the mesophyll in the rolled leaves and pupate through the winter.

Control methods: after the larvae are found, they can be sprayed with fenitrothion diluted 1000 times or fenvalerate diluted 4000 times.
