There are many borers in the main branches of fruit trees, how can these borers be eliminated?

Different methods can be taken according to the situation, the first kind, if there are more aphids or borers, you can spray some special insecticidal agents, the second kind, if the number of insects is not much, you can spray it with lime or vinegar water, which also has the effect of repelling insects.

First of all, it is necessary to spray pesticides against this kind of borer, and secondly, it is best to introduce woodpeckers, and then eliminate this kind of borer, which is the most scientific and reasonable method.

I think the best way to get rid of these borers is by spraying pesticides, which is very effective.

I think we should spray some pesticides on the fruit trees so that there are no borers, otherwise the fruit that grows later will not be safe.

The diseases that harm the apple orchard are: rot disease, powdery mildew, anthracnose, ring disease, spotted defoliation, brown spot, root disease, rust, fruit branch ulcer, etc., the main insect pests are: peach heartworm, small leaf moth, leaf mites, goldenrod moth, yellow moth, tumor moth, etc., 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 dead leaves of the plants, especially the parts that are susceptible to diseases, should be pruned and pruned, and the pruned branches should be removed in time and incinerated in other 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, turn the moisture deeply, and carry out targeted pesticide treatment, and spray the new high-fat film to enhance the efficacy, thoroughly, and control the overwintering 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 insect control and disease resistance of the plant 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.

Don't be afraid of growing insects on fruit trees, you have to know what kind of insects they are, aphids or green flesh insects. Once you've figured it out, it's okay to prescribe the right medicine. It would be good to spray the right pesticides to control insects.

The answer is to apply pesticides: take targeted measures, and directly use the corresponding pesticides according to the type of pests to apply them to the trunk of the insects, which can generally have an insecticidal effect. Wormhole Potation:

After the pesticide or insecticide is prepared, it is directly poured into the wormhole, and at the same time, a little fertilizer is applied to the fruit tree in an appropriate amount to enhance the tree's strength. Sawing off tree trunks: Cut off the trunks of trees that have insects, then find the insects to kill them, or cut them off and burn them directly.

Fruit trees should be sprayed with insecticides, as for what insecticides to use, it depends on what kind of insects, after you go to the place where pesticides are sold, the seller will recommend suitable pesticides to you.

What drugs should be used for insecticide of fruit trees should be determined according to specific pests, and the drugs targeted by different pests are different. If there is aphid damage, imidacloprid or acetamiprid can be sprayed. In the case of spider mites, avermectin or acetidazole can be used.

In the case of scale insects, mineral oil can be used. In the case of psyllids, thiamethoxam or dinotefuran can be used.

Inject an appropriate amount of 40 dimethoate EC (5-10 times liquid) or 50 methamidophos EC (3-5 times liquid) and other drugs into the wormhole with a syringe, and then seal it with yellow mud to avoid the volatilization of the liquid after injection, and its control effect can generally reach about 98. Mothballs: Cut mothballs into medium-sized pieces, then stuff them into worm holes (3-5 grains in each hole), and finally seal them with wet yellow mud to prevent air leakage.

Brush a layer of lime on it, or add a potion, and you can kill the worms.

Injection drug: Use a syringe to inject an appropriate amount of 40 dimethoate EC (5-10 times liquid) or 50 methamidophos EC (3-5 times liquid) and other drugs into the wormhole, and then seal it with yellow mud to avoid the volatilization of the liquid after injection, and its control effect can generally reach about 98.

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.

The orchard should be cleaned thoroughly. 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.

It can be smoked with medicated medicine, and tung oil can be used to kill insects. Be sure to deal with the problematic plants in a timely manner, and you can also spray some pesticides.

It can be solved by spraying pesticides, be sure to pay attention to the cleanliness and hygiene of the surroundings, and clean up the weeds in time.

Be sure to spray pesticides in time, but also pay attention to the use of fertilizers, must be targeted, can not be scattered at will, but also pay attention to the growth of plants.

How do you get rid of the borers in the trunks of fruit trees? Find out how to do it in detail.

Dip 5-10 times of 80% dichlorvos EC or 40% dimethoate EC with cloth strips or waste paper, and stuff them tightly into the cavity; Or use a veterinary syringe to inject the liquid. 2.It is also possible to use 56% aluminum phosphide tablets (about 3 grams per tablet), divide them into 10-15 small grains (each serving of York), stuff one small grain into each cavity, and then seal the hole with soil.

3.Use a poison swab to insert a cavity to poison the larvae (the poison swab can be made with zinc phosphide, peach gum, oxalic acid and bamboo skewers). 4.

Hook larvae: When the larvae are still eating under the cortex of the root neck, or when they are not deep in the xylem, they should be hooked in time. 5.

Simple prevention and control: the use of woven bags for packaging fertilizers, etc., after washing, cut into a long strip with a width of 20-30 cm, before the star cattle lay eggs, in the main part of the easy to lay eggs, with the cut braided strip wound 2-3 times, each circle between the connection does not leave a gap, and then with hemp rope binding, the prevention and control effect is very good. Through bandaging and barrier, the longhorn beetle can only put the eggs on the braiding bag, and then the eggs will lose water and die.

6.**Damaged tree: During the peak period of root growth from Qingming to Lixia, choose a sunny day, dig up the root neck soil clod of the tree infested by Xingtianniu, scrape off the wound residue with a sharp knife, make the wound appear fresh color, apply rooting powder at the wound (it can also be coated without coating), and then pile the manure around the wound, and cover the film block, the upper end of the film block is tightly tied with hemp rope against the trunk, the lower end is spread on the fertile soil, and finally covered with the excavated soil and pressed.

Soon, the wound produces a callus, re-sprouts new roots, and the plant regains its vitality.

You can use plant ash water to pour into the trees, so that the fruit trees can recover better, there will be no problems, in the winter spray the grass ash water on the surface of the trees, so that you can prevent pests, or you can spray pesticides on the surface of the fruit trees, so that you can also prevent borers, you can use this method, so that you can make the fruit trees healthier.

You can sprinkle some insect repellent on the fruit trees, and you can also raise some woodpeckers in the orchard, so that you can prevent insect borers. You can raise woodpeckers, you can also sprinkle some pesticides, you can also sprinkle some insect repellents, and you can also sprinkle some insecticides.

At this time, you need to spray some insecticides to repel insects. Insecticides should be used when the plant is just growing, and it is necessary to maintain a good planting environment and regularly check for insect pests, so as to prevent pests.

Use a knife to cut open a part of the tree to remove the moth, or you can spray insecticide into the hole of the tree. Clean up weeds regularly, apply pesticides regularly, and apply pesticides that are resistant to insects.

Moths, the individual is relatively small, most of the annual generation to the larvae overwinter, the next spring pupa month pupa into an adult, the adult mating after the egg lay, the egg period of about 15 days to hatch the larvae will burrow into the wood or fur harm, is an important pest of agriculture and forestry, wood decoration and furniture and wood carving Buddha handicrafts, fur clothing. Paint treatment, for some corners that have not yet been damaged by moths, use raw tung oil, shellac paint or varnish and other coatings to brush to the surface of the wooden cabinet, which can isolate the moths from the air and achieve the purpose of moth-proofing. It should be noted that when painting, the front and back sides and the inner wall of the wooden cabinet should be painted evenly in place.

Pesticide treatment, when the wooden cabinet is moth-eaten, you can use a sprayer to fully spray the net welling borer medicine, so that the liquid medicine can penetrate into the wooden cabinet, to spray 3 5 times in a row, after 8 hours, can kill all the moths. After that, wash the wooden cabinet with clean water and dry it. Wipe with diesel, put the wooden cabinet that has been eaten by insects in the morning sun on a sunny day, and paint all the wooden cabinets with a brush or cotton yarn dipped in diesel fuel once.

Dry for two or three hours and then apply it once, and then dry it again, until you see the moth dead at the mouth of the hole. Then wash it with laundry detergent and dry it.
