Embodiment 1

[0020] In the first ten days of April, choose coconut bran as the water-absorbing material, plastic film (commonly used in agriculture, commercially available) (width 1m) and some rubber strips (commonly used in construction, commercially available), fold the plastic film in half horizontally, and loosely wind Huolinan (commercially available) Michelia macclurei Dandy var.sublanea Dandy) The base of the trunk of Michelia macclurei Dandy var.sublanea Dandy) was bandaged 2 to 3 times, the lower end of the plastic film was fastened, and the space between the plastic film and the trunk skin was filled with coconut bran. The thickness of the last coconut bran layer was about 3cm, and the height was about 30cm; then pour omethoate diluted 80 times into coconut peat until the adsorption is saturated, and finally tie the upper port of the film tightly to reduce the rainwater from the tree trunk flowing into it during rainfall, and at the same time avoid the loss of medicinal liquid and ...

Embodiment 2

[0022] The present embodiment is basically the same as Embodiment 1, except that the object of treatment is Manglietia megaphyll a Huet Cheng, and the omethoate poured into coconut bran is diluted with water by 120 times.

[0023] After one year of continuous control, it was found that the above-mentioned trees that had been sprayed grew well, indicating that the application of pesticides had no adverse effects on their growth. After inspection, the crown of the tree did not have the Pythias aegyptus, and the population reduction rate of the Pyramids aegyptis reached 100%. The control rate is 100%, and the control effect is very good.

Abstract

The invention discloses a method for controlling tall tree Icerya aegyptiaca. The method comprises the following steps: a container around a tree trunk is arranged at the bottom of the trunk of a tall tree, a water absorbing material is filled in the container to ensure that the water absorbing material contacts with the epidermis of the tree trunk, then diluted omethoate (the dilution multiple is 80-120) is injected in the water absorbing material until the water absorbing material is saturated, and the container is sealed. The method for controlling tall tree Icerya aegyptiaca is simple and effective for tall trees, particularly the crown part is effectively controlled; and the labor intensity is greatly reduced, and the risk that liquid medicine falls on the operator can be avoided. By adopting the method for controlling Icerya aegyptiaca, the effect is good, the normal growth and ornamental value of the tree can be ensured, and the popularization and application of tall trees of the Magnoliaceae and Moraceae in landscaping can be ensured.

Description

Technical field: [0001] The invention belongs to the scientific and technical field of disease and insect pest control, and in particular relates to a method for preventing and controlling the cotton scale of tall trees. Background technique: [0002] With the acceleration of urbanization, the concept of urban greening is getting more and more attention. The government garden management department and urban construction planning department choose more and better tree species to beautify the city and optimize the environment. Among them, many plants such as Magnoliaceae and Moraceae Category already plays an important role in this. In addition, some parks, schools, living quarters, etc. value the advantages of magnolia plants such as beautiful plant shape and bright colors, which makes magnolia plants more and more widely used. However, these plants have been severely damaged by Icerya aegyptiaca in southern China in recent years. [0003] In our country, the cotton cicada ...
