What is the reason why huanghuali trees have worms?

With the gradual development of artificial cultivation of Huanghua pear in Hainan, it is necessary to control the corresponding diseases and insect pests. Huang Huali tree grows slowly, just like a person's life, it will be more or less morbid. If you are ill, you should see a doctor. The same is true for Huang Huali trees, which will encounter some pests and diseases.

It was found that the most common diseases of Huanghua pear in Hainan were nevus and anthracnose. Mole disease is the main disease of Huanghua pear from seedling stage to late growth stage, which usually occurs in high temperature and high humidity environment. At the beginning of the disease, the leaves of Huanghua pear will produce small spots, and then gradually become larger. In severe cases, even the whole leaf will turn black and die.

However, anthracnose usually occurs on tender branches and leaves, and pests such as marmots and inchworms can also harm larger trunks or branches and can be killed manually. In view of the first two diseases, we should focus on prevention and control, strengthen fertilizer and water management and improve plant stress resistance.

Trimming, shaping and weeding at the same time. Keep the woodland ventilated and transparent, and reduce pathogens. At the onset, 70% mancozeb wettable powder or 50% thiophanate-methyl wettable powder is sprayed with 800- 1000 times solution every 5-7 days and continuously for 2-3 times.

In the case of insect pests, it should be noted that longicorn beetles linger in the heart, and small trees that are bitten to death often cause wind break or death. The control method can use 300-400 times solution of 90% trichlorfon or phoxim in the larval stage, inject it from the wormhole with an animal syringe, and seal the orifice with a cotton ball to suffocate it. Other general pests can be controlled by conventional methods.
