Effective fruit tree pest control

The problem of fruit tree pests and diseases is now becoming more and more serious. One of the reasons is that there are many kinds of pests and diseases, and the number of pests and diseases is fast, which leads to the rapid increase in the number. In the spring and summer, when the fruit growers began to plant fruit trees, the weather was warm and appropriate, and it was just a good time for pests to appear. Therefore, the prevention and control of fruit trees and pests at this time is particularly important. However, in actual production, fruit farmers lack knowledge of pest control, and they do not know enough, and there is no professional prevention mechanism and corresponding rescue measures. They miss the best time for prevention, and pests and diseases spread more rapidly. Let's summarize the prevention and control measures of fruit trees and pests. Let's take a look!

1, the trunk package cures aphids

Select a smooth belt with a width of 15cm from the ground 30cm to tie the absorbent material such as cotton and newspaper, and spray the diluted pesticide on the absorbent. Then use the film to tighten it for 100 days. The treatment of the fruit tree aphid is very Effective.

2. Bagging the fruit to prevent the pests of the fruitworm from spawning

When the fruit grows to a certain extent, the fruit is bagged with a relatively transparent bag, which can well prevent the pests and diseases, and at the same time, it can avoid pesticide residues due to physical control methods, and is a green pest control. law.

3. Apply glue or white on the trunk

It can effectively prevent pests and diseases from spreading and spreading. On the one hand, it can prevent the pests from the ground from climbing to the fruit trees to cause harm; on the other hand, for the fruit trees that have caused pests and diseases, the painting can Effectively stop the spread of pests on fruit trees and pests to other fruit trees without pests and diseases, which is a kind of protection for other fruit trees.

4, light traps pests

Using the phototaxis of pests, a 20w black light fitting inducer was used in the night to trap the pests in the orchard. If necessary, you can add a power grid near the lights, which can improve the killing effect.

5, using physical color to attract insects or deworming

Use pests' color tropism to trap or drive off pests. The yellow armyworm board can be used to trap the aphids, and the aphids are driven away from the aphids to achieve the purpose of pest control.

6. Chemical methods to control fruit tree pests and diseases

When using chemical pesticides for pest control, special attention should be paid to resolutely eliminate the use of “three high, three high” (high toxicity, high residue, high pollution, carcinogenic, teratogenic, mutagenic) pesticides, based on forecasting and forecasting. Use chemical pollution-free pesticides for chemical control. Traditional fine pesticides such as stone sulphur mixture and Bordeaux mixture should be retained, and some plant extracts should be promoted to control pests and diseases. Also pay attention to timely medication, reasonable preparation, minimize the pollution of pesticides on the environment and fruits, and ensure the safety of fruit consumption.

7, natural enemy method to control fruit trees and pests

The introduction of natural enemies of pests to control pests is an effective method of prevention and control. Some birds are specialized in eating pests and will not cause damage to the orchard, but it should be noted that the ecological balance between the two cannot be broken. In the prevention and control of natural enemies, China has carried out a lot of scientific research, for example, in the application of Trichogramma to control pine caterpillars, and the control of American white moths. When using natural enemies to prevent and cure, one must pay attention to reducing the number of chemical prevention and control. Second, it is necessary to apply low-toxic and pollution-free pesticides, otherwise it is difficult to achieve good results.

8. Microbial control of pests and diseases

Microbial control has also been gradually applied to all major fruit forest areas. The use of biological agents to control pests and diseases can reduce the pollution of pesticides on fruits and the environment, as well as reduce phytotoxicity and human and animal damage. For example, Bacillus thuringiensis is the most widely used microbial insecticide in the world , and it has a good effect on the control of apple leaf curler and fruit tree pests. For example, it is effective to control lepidopteran pests by using the chlorpyrifos which reduces the molting, the chlorpyrifos and the rice bran which increases the speed of the rind. Spraying sterilization hormone, azadirachtin, nicotine, rotenone, etc. can effectively control many pests and pests. Agricultural anti-120, agricultural streptomycin, polyoxomycin, etc. produced during microbial fermentation can effectively control certain pathogens. It should be noted that it cannot be mixed with chemical fungicides.
