Biological or chemical control is carried out. The so-called biological control is the introduction of natural enemies of their pests and the like. Chemical control is the use of pesticides. For orchards, direct pesticides are best!

The incidence of beetles, aphids, planthoppers, leafhoppers, thrips, mealybugs, mites and leaf miners in orchards is faintly on the rise. But now don't worry, now in the major orchards, traps, insect traps, detection lights, insecticidal lamps, spore traps and other professional insect control and insect control equipment applications are commonplace, and the application effect is good, especially the emergence and application of Yunfei Technology orchard solar insecticidal lamp is to achieve a win-win situation of orchard ecological and economic benefits, and play a miraculous effect in the development of the fruit industry.

What if there are too many pests in the orchard? First of all, see the pests in the orchard, and then choose to buy pesticides according to the pests and come back to kill them, so that the fruit trees can grow densely.

Fruit trees are often attacked by pests and diseases in the process of growth, which can lead to a decrease in yield and fruit quality, and will cause fruit trees to be out of production and die, so the problem of pest control can never be ignored. In addition to emphasizing prevention first and comprehensive prevention and control, prevention and control work should also focus on reducing pollution and reducing costs.
How to prevent and control orchard pests and diseases effectively with pesticides?
When pests and diseases are found in orchards, farmers generally choose pesticides to deal with them, but the use of pesticides in large quantities will not only pollute the environment, but also endanger human health with residual pesticides. In addition, if a pesticide is used for a long time, pests and diseases will develop resistance, so pesticides should be used scientifically and rationally.
1. The application time should be appropriate. That is, to grasp the occurrence law of pests and diseases, and to control them in the critical period. It has been proven that if the application time is appropriate, it can not only effectively control pests and diseases, but also greatly reduce costs.
2. The selection of pesticide varieties should be correct. In order to achieve the effect of rapid insect extermination, some fruit farmers will use large doses of pesticides, which on the one hand increases the cost and on the other hand, it also destroys the agricultural production environment. Therefore, the selection of pesticide varieties and pesticide dosages should be carried out according to the types of pests, the scope of prevention and control, and the harmfulness, and must not be blind.
3. The use of pesticides should be scientific. If a pesticide is used for long-term control, it will make the pests and diseases develop a certain resistance, and the effect of the pesticide will be greatly reduced. In practice, several pesticides can be used alternately or in combination.
At the same time, it is also necessary to use green pesticides that are less polluting to the environment and harmless to the human body as much as possible. In addition, the concentration of pesticides used should be reasonable and the application should be thorough.
The number of pests and diseases in fruit trees is actually accumulated over the years, the longer it is not cleaned, the more the number of pests and diseases will be, and when it reaches a certain number, it will cause direct damage to fruit trees, so it is necessary to control the reproduction of pests and diseases from the source. At the time of the autumn and winter season, fruit trees have more fallen leaves and fruits, so it is necessary to clean up these fallen leaves, fallen fruits, weeds and other garbage in time to prevent diseases and insects from hiding in them for winter. At the same time, it is necessary to remove the bark of the trunk and the rot spots on the trunk to remove the germs and eggs that are hiding in the cracks in the trunk to control the number of pests and diseases.
Garbage can be disposed of by centralized burning. In addition, it is necessary to pay attention to the timing of pest control. Rain can promote the growth of fruit trees, but it can also spread diseases.
Therefore, when the rainfall is abundant, attention should be paid to strengthening the control of pests and diseases; In drought, pests and diseases have a strong reproductive ability, so we should focus on insect control at this time.

If you want to prevent it, you must spray pesticides in time, and when the fruit has not grown, you should first sprinkle it once, and then after the fruit grows, you also need to actively spray pesticides, and when spraying pesticides, you must find a weather that does not rain. In this way, it can effectively prevent pests and diseases.
-
First of all, this is according to the crops planted, and then to choose their own pesticides, should pay attention to the appropriate concentration, should also pay attention to the appropriate use time, but also need to grasp the best time, do not choose the temperature is relatively high, pay attention to protect the individual**.
-
Be sure to proportion, spray pesticides in a timely manner, choose the right pesticides for spraying, and can also be sprayed with other drugs, so that you can better solve the problem, you must pay attention to the weather.

Insect exterminants can be applied, so that pests will be destroyed.

There are too many pests in the orchard to spray pesticides.

The types of natural enemy insects can be divided into predatory natural enemies and parasitic natural enemies mainly according to their insecticidal methods. 1.There are many types of predatory natural enemies, the most common are dragonflies, praying mantises, hunting bugs, spiny bugs, flower bugs, lacewings, ladybugs, walking bugs, insectivorous flies, aphid-eating flies, wasps, mud wasps, spiders, and predatory mites.
2.Parasitic natural enemy insects: red-eyed wasps, tasseled bees, cocoon wasps, parasitic flies (one of the parasitic natural enemies of agricultural, forestry, fruit and vegetable pests), wasps.

The diseases that harm the apple orchard are: rot disease, powdery mildew, anthracnose, ring pattern disease, spotted defoliation, brown spot, root disease, rust, fruit branch ulcer, etc., and the main insect pests are: peach heartworm, small leaf curl moth, leaf mites, goldenrod moth, yellow moth, tumor moth, etc., and the annual loss to fruit farmers can reach 20% of this income.
Prevention and control methods: 1. Prevention and control of diseases. Before the onset of the disease, it is necessary to carry out pesticide killing treatment according to the requirements of plant protection, and add a new high-fat film to improve the control effect.
Before winter, the plants should be pruned and pruned, especially the parts that are susceptible to disease, and the pruned branches should be cleaned and transported in time and incinerated in different places to remove the virus**. The pruning mouth should be coated with callus antiseptic film to promote wound healing as soon as possible, and all plants in the garden should be sprayed with tree protectors to improve their ability to prevent cortical pests and diseases and inhibit virus replication, and resist various bacterial infections. 2. Pest control:
Before winter, we should completely remove the weeds between the surface bushes, and turn the moisture deeply, and carry out targeted pesticide treatment, and at the same time spray a new high-fat film to enhance the efficacy, thoroughly, and control the wintering environment of pests. The pest control of different growth periods should be targeted according to the requirements of plant protection, and new high-lipid film should be applied to enhance the control effect. It is also necessary to spray the tree protector regularly to enhance the plant's ability to prevent branches and insects and resist diseases, and ensure its healthy and strong growth.
3. In the bud stage, young fruit stage and fruit expansion stage, it is necessary to apply a strong fruit to strengthen the flower and fruit, and enhance its ability to resist diseases and pests.
