What medicine should be used to treat insects on the lucky tree? How to eradicate scale insects on the lucky tree?

1. Scale insects

Scale insects are a very common pest that mainly harms the stems and leaves of the lucky tree. They are prone to occur in seasons of high temperature and high humidity, especially in poorly ventilated environments. If you want to get rid of this pest, it is difficult to use pesticides alone. You need to use a wet rag or transparent tape to capture the adult insects. In addition, if you want to prevent the larvae from hatching, you can spray 1000 times the solution of cypermethrin.

2. Red spider

Red spider mites are not spiders but a type of mite. This pest can cause the new leaves of the lucky tree to become wrinkled and curled, and the surface to be uneven. They usually appear in large numbers from June to September, especially when the temperature is high and the air is dry. If the environment is humid, they will be much less. This type of pest is usually killed by spraying with special mite-killing agents such as cypermethrin and nisolan.

3. Aphids

There are many types of aphids, which usually feed on plant sap. For the lucky tree, the most common one is the green peach aphid. This pest causes the leaves of the plant to become wrinkled and deformed, as well as to have honeydew spots. This pest is relatively large and easy to find, and is usually eliminated using drugs such as chlorpyrifos, omethoate, and diazinon.

4. Whitefly

Whitefly is also a very common pest. In addition to directly harming plants, it may also transmit diseases. In addition, its excrement will affect the plant's respiration and hinder its photosynthesis. Usually in the early stages of the disease, you should use pyridoxal or cypermethrin to spray, usually once every 5-7 days, and 2-3 sprays are enough.
