Citrus is a common fruit in life. What are the new technologies for integrated control of pollution-free citrus pests and diseases? In recent years, excessive pesticide residues in fruit and vegetable products have been a hot issue, and how to prevent and control pests and diseases is a major issue in the cultivation of fruit and vegetable products. Citrus is a very important fruit crop, and the prevention and control of diseases and pests is of great significance for improving farmers' economic benefits and promoting export trade. On this basis, the new integrated control technology of pollution-free citrus pests and diseases was analyzed, hoping to provide some reference for relevant personnel.

Citrus plays a very important role in fruit tree planting. During its growth and development, diseases and pests will occur widely, which will do great harm to the healthy growth and fruit of citrus, thus endangering the final yield and quality of citrus. Therefore, it is of great application value to carry out scientific research on the new technology of comprehensive prevention and control of pollution-free citrus pests and diseases. Let's take a look at the new technology of integrated control of pollution-free citrus pests and diseases.

1. Improve the agricultural control technology First of all, the pollution-free integrated control technology of citrus pests and diseases must improve the agricultural control technology and use some agricultural technologies to effectively control citrus pests and diseases. Agricultural control technology must strengthen the water and fertilizer management methods of citrus to enhance the ability of trunk to resist pests. For citrus plants, early watering and drainage pipes should be carried out, at the same time, enough soil water content should be maintained to prevent the plants from being flooded, and balanced fertilization should be used to promote the healthy growth of citrus plants.

In a word, it is of great significance to strengthen planting management methods for citrus pest control. Secondly, it is necessary to improve the stem structure in agricultural control technology and ensure reasonable pruning, which can reasonably reduce the occurrence of pests and diseases. Compared with traditional plant pruning, the new agricultural control technology should pay attention to maintaining a good trunk group structure, which is an important part of the new agricultural pest control technology.

2. Physical control Physical control is an important technology of new pollution-free citrus pest control technology, which refers to mixing seeds in water at 50℃ before planting to select some clean and high-quality seeds, and soaking them for 8 hours after the water is cooled, so as to reasonably eliminate microorganisms on the surface of seeds and improve their ability to resist pests and diseases. In addition, the new physical control technology also includes the application of some light bulbs or black lights to trap and kill pests, such as ground tigers and cicadas.

Moreover, cotton aphids in citrus diseases and insect pests have the characteristics of avoiding dark gray and turning yellow, so yellow board can be used to attract aphids, and silver-gray film can be used to drive aphids away to prevent diseases, which is also the core technology of new physical control technology. In addition, for some small black cutworms and other pests, sugar and wine vinegar can be used to trap and kill them, or a sunshade net can be used to prevent moth. This new physical control technology has played an important role in the new comprehensive control technology of pollution-free citrus pests and diseases.

3. Biological control The specific method of biological control is to use microbial nemesis of some pests and diseases in nature to control them. For example, ladybugs can be used to control some mites, which can reduce pests and diseases such as scale insects and Huanglongbing. In addition, bees can also be used to control insects and moths, which can reduce the harm of pests to some citrus fruits and branches.

It can be seen that biological control is a very reasonable new way to control citrus diseases and insect pests. Biological control is not easy to pollute the natural environment, and it will not endanger other safety. It is a new technology that should be developed vigorously in the comprehensive control technology of pollution-free citrus. According to beneficial microbial compounds, it has good control effect on citrus diseases and insect pests.

In addition, biological pesticides are also an important way in biological control. In biological pesticide control technology, we should adhere to the principle of "nurturing is more important than prevention, and prevention is more important than cure". Because the use cost of biological pesticides is very high, it is necessary to focus on improving the resistance of citrus plants and using drugs in advance according to biological pesticide technology, so as to implement reasonable pest control.

For example, in the case of biological pesticides to control planthoppers and budding insects, 1.8% avermectin 3000 ~ 5000 times spray and 1% matrine soluble agent 1000 times spray can be used, and good control effect will be achieved when used in infancy. Finally, there are some common problems in the application of new biological pesticide control technology.

For example, biological pesticides are generally used together, and cannot be mixed with some chemicals, alkaline and acidic pesticides. In addition, biological pesticides should be well controlled when spraying, and many biological pesticides need to be used continuously for 2 ~ 3 times to feel better control effect.

4. Ecological control Finally, in the new technology of pollution-free citrus pest control, we should look for improvements in ecological control. It can create a better ecological environment for pollution-free citrus planting and prevent pests and diseases from the source. In addition, for the relevant departments, it is necessary to improve the overall local ecological environment and appropriately tilt some manpower and financial resources.

In addition, in the new control technology, it is necessary to grasp the characteristics of pests and diseases in the process of pollution-free citrus planting according to ecological control, so as to construct the relevant training system of citrus pest and disease control technology, continuously improve the planting level of pollution-free citrus, and solve the pest and disease problems of pollution-free citrus according to ecological control.

Three. Conclusion To sum up, there are many kinds of diseases and insect pests in pollution-free citrus. In the new technology of integrated pest control, we should first improve the agricultural control technology, and then attach importance to the new physical control technology, and make more use of some new technologies to trap and kill pests to ensure the planting safety of pollution-free citrus. In addition, we should make rational use of biological control technology, especially the use of some biological pesticides. Finally, the new technology also includes ecological control, which solves problems from the source of ecological environment, thus effectively controlling pests and diseases.
