How to treat insects in peach trees? What medicine is used to kill insects in peach trees?

After the peach tree falls flower, when it grows to the time of lush branches and leaves, or when it has already borne fruit, it is particularly easy to grow aphids, and spraying imidacloprid can effectively control aphids.

First of all, you can spray the peach tree with pesticides at regular intervals in the middle of each month, but you should not spray too much at one time.

How to prevent and control peach tree scale insects and how to kill scale insects.

Common insect pests of peach trees are: peach aphid, flat ball scale, mulberry white scale, peach borer, peach moth, and a little leafhopper.

There are 11 insect pests such as heartworms, and the insecticides for the control of peach tree pests correspond to the following:

Pesticides to control peach aphids. There are mainly mineral oils.

Emulsion, diesel emulsion, stone sulfur mixture, melt scale, quick culling, phosphorus, imidacloprid.

Aphidlice, Kangfudo, Emilor, Jin Haonian, Haonian, Anti-Aphid, Prothiocarbofuran, Acetamiprid, Mobile, Actet, Thiametoxam, Endosulfan, Saidan, Atoli, Alfat, Azerin, Worm Saidie, Green Pepsi.

annihilation, etc. Pesticides for the control of flat bulb scales. There are mainly mineral oil emulsions, coafen, diesel emulsions, stone sulfur mixtures, cocoon melting, rapid culling, phosphorus killing, Youled, etc.

Pesticides for the control of mulberry white scales. The main ones are mineral oil emulsion, cocarin, diesel emulsion, stone sulfur mixture, fused scale, phosphine, rapid culling, prochlorine, eulot, thiazinone, etc.

Peach tree disease control methods.

1. Dormancy period to before germination: in autumn and winter, remove dead branches and leaves, bury them deeply or burn them; Combined with winter pruning, prune the branches of diseased insects and dead fruits; Turn over the tree tray and scrape off the old rough warped bark, diseased tumors, disease spots, etc. Before winter, spray the branches of the tree with 100 times of 5% bacterial poison water agent, and then paint the trunk and large branches white.

Before budding in spring, the whole tree is sprayed with a baume 5 degree stone sulfur mixture.

2. Germination to flowering period: when the flower buds are white, control aphids and scale insects.

10 imidacloprid wettable powder 2500 times liquid and 25% chlormethalin wettable powder 1500 times liquid spray can be used; To control leaf mites, spray with 2500 times of 20% mite dead suspension; For disease control, 50% carbendazim wettable powder 600 times liquid can be used for tree spraying; Manually scrape the rot disease, and apply the scar with 843** agent 10 times liquid.

3. Fruit expansion period: 15 days after leaf development, for disease control, you can choose 70% mancozeb wettable powder 800 times liquid or 70 methyl tobuzin.

600 times the liquid wettable powder for spraying; After flowering, control aphids and leaf mites, with matrine.

300 times liquid liquid or 20% 2000 times liquid spray of emulsifiable concentrate.

To control heartworms and peach borers, spray with 20% fenvalerate emulsifiable concentrate 2000 times; To control leaf curling moths, spray with 1500 times of 25% chlorpyramide No. 3 suspension. Artificial excavation of red-necked longhorn larvae;

1. Peach bacterial perforation disease.

Spray 4-5 degrees of stone sulfur mixture or 1:1:100 times Bordeaux liquid before germination, and spray 800 times of Cobo solution once after flowering.

From May to August, spray agricultural streptomycin (10,000-20,000 times) or zinc ash solution (1 part of zinc sulfate, 4 parts of lime, 240 parts of water) or 600 times of 65% zeb zeb wettable powder.

2. Peach scab.

Also known as scab disease: it mainly harms fruits, but also affects new shoots and leaves. The disease is mostly found in the shoulder.

The lesions on the fruit are green and watery at first, and then turn black-green and nearly round after enlargement. When the fruit is ripe, the lesions turn purple or dark brown, the lesions are confined to the peel and do not penetrate deep into the pulp, and the later lesions become corked and cracked.

Spray 80% sodium pentachlorophenol 200 times plus 3-5 Baumé stone sulfur mixture before germination; Half a month after flowering to July, about every 15 days, spray 50% carbendazim wettable powder 800 times or zeb wettable powder 500 times, or Fuxing 8000-10000 times, all of which are effective for this disease.

If you want to have a better insecticidal effect on peach trees, you can add an organic fluorine anti-anti-synergist when you apply pesticides to peach trees, which can effectively improve the effect of pesticides, eliminate insect pest resistance, and have a better control effect!

1. Imidacloprid.

Imidacloprid has a strong multiple drug effects such as contact killing, systemic absorption, and stomach toxicity to kill aphids, and also has a certain insecticidal effect on leaf curling moths. In general use, 10% imidacloprid wettable powder 3000 times solution is selected, which can be used in the autumn and winter insect egg hatching period and adult stage, and is used once every 7-10 or so, and 2-3 times in a row.

2. Scallop full of spirits.

Cocole, also known as engine oil emulsion, can be used as a contact killer to control mulberry white scale nymphs and aphid eggs, overwintering mites, etc. The use time is generally after the peach buds germinate in spring, and the concentration of 95% cocoon is 100-150 times the solution.

3. Tachycarmonone.

Tachycarone has a good insecticidal effect on red spiders, aphids, and thrips, and the use of 20% tachycarone wettable powder 3000 times liquid spray at the location where the insect infestation occurs, the general effect can last for about 30 days.

What are the pests of extended peach trees.

1. Aphids. Aphids are more harmful to peach trees and are a very common pest of peach trees. The cause of insect infestation is generally that the temperature and humidity change drastically in spring, which is easy to cause aphids to multiply, and the aphid infestation is generally most serious in May.

2. Mulberry white scale.

The female adults and nymphs of the white scale eat the new shoots and fruits of the peach tree, causing a significant decrease in yield.

3. Red spider.

Spider mites mainly damage the leaves of peach trees, causing defoliation and loss of peach fruit quality.

Peach tree pests and diseases: prevent aphid resistance, rotate pesticides to prevent aphids!

The prevention and control of peach tree perforation disease and preventive measures are as follows: 1. Pay attention to drainage in peach orchards, increase the application of organic fertilizer, avoid partial application of nitrogen fertilizer, and prune reasonably to ventilate and transmit light to the peach orchard, so as to enhance the tree potential and improve the disease resistance of the tree.

2. After germination, spray 500 700 times of 20% thiazole copper suspension and spray evenly, or spray 600 1000 times of 40% thiazole zinc suspension, or spray 600 800 times of 20% thiazole wettable powder and 200 times of 4% chunleimycin wettable powder. Fruit farmers should pay attention to the choice of pesticides to use alternately, do not always use the same formula, so as not to develop resistance and reduce the control effect.

Pesticides commonly used on peach trees.

Bacillus thuringiensis: Bacillus thuringiensis is a microbial pesticide with stomach toxicity. With 8000IU mg of Bacillus thuringiensis suspension 200 times liquid, used in the evening or cloudy day on a sunny day, evenly spray the crop leaves, the application period is the peak hatching period of pest eggs to the young larval stage, which can effectively control peach tree inchworms and heart-eating insect pests.

The agent can not be mixed with fungicides, alkaline pesticides, organophosphorus insecticides, etc., and needs to be re-sprayed in case of rain within 6 hours after application.

Peach trees are planted all over China because of their strong ability to grow. Compared with other regional fruits, the yield is also relatively large. However, sweet and delicious peaches are threatened by pests and diseases, and eliminating pests and diseases from peach trees has become one of the major tasks.

Next, let's introduce how to get rid of pests and diseases in peach trees.

Agricultural control techniques for peach tree pests and diseases

1. Reasonable layout to prevent mixed planting of peaches and pears and avoid rampant harm of small solid pear insects. The larvae of the pear small solid insect generation mainly harm the peach tree generation mainly harms the fruit of the pear, and if two kinds of fruit trees are planted in one orchard at the same time, it will cause serious harm. Therefore, separation zones should be set up whenever possible.

2. Scrape off diseased tissues and warped skin. Peach trees often have branch diseases such as gum disease and rot disease, which can be effectively controlled by manually scraping the diseased tissue and then applying pesticides such as 843**.

3. Reasonable pruning and pruning of diseased and insect branches. Pruning of peach trees is divided into winter and summer pruning. When pruning in winter, you can cut off the branches harmed by the bulb scale and the mulberry scale, the branches where the grasshopper lays eggs and the diseased fruits and stiff fruits left on the tree.

One of the most effective ways to prevent and control the disease is to prune the disease, burn it intensively or bury it deeply.

4. Reasonable fertilization and irrigation. More application of organic fertilizer, reasonable application of chemical fertilizer, and timely irrigation can promote the growth of peach trees, make the tree healthy, and the damage of diseases and insects is light; On the contrary, the damage of pests and diseases is serious. In addition, peach trees are extremely waterlogging tolerant fruit trees, so they must be drained in time during the rainy season.

5. Remove dead branches and leaves, and pay attention to the hygiene of the peach orchard field. After the peach tree has fallen leaves, combined with winter pruning, it can remove the dead branches, fallen leaves, weeds, etc. in the peach orchard in time, and bury them deeply or burn them intensively, which can eliminate the source of overwintering insects. In addition, it is necessary to pay attention to the hygiene of peach orchards during the growing season.

6. Sweet and sour liquid traps adult insects. Use sweet and sour liquid into a bowl or small jar to act as a trap. Sweet and sour liquid recipe:

Brown sugar, 1 part vinegar, 10 parts water, and a small amount of liquor are ready. When using, hang the trap on the tree with wire or rope, remove the dead insects every day, and replenish the sweet and sour solution to the original water line.

7. Wrap the trunk around the straw. Using the habit of laying eggs on the trunk of the tree or overwintering under the warped skin and in the crevices of the skin, the peach-necked beetle, the pear heartworm and the hawthorn leaf mite are used to entangle the grass on the trunk to attract these pests.

8. Black light traps and kills adult insects. The installation of black light in the peach orchard can trap and kill a large number of peach borers, leaf rollers, peach leafhoppers and other adults.

Hello, happy with your question.

About: When is the best time to treat insects in peach trees.

Spring is the key time for the prevention and control of scale insects, the beginning of March to the beginning of April in Luxi area is the incubation period of peach tree scale insects, as long as this period of time to spray pesticides for control, you can achieve a good control effect, spray once every 6 8 days, until the elimination. The effective agents are: 50% chlorpyrifos 1500 times, 10% imidacloprid wettable powder 2000 times, avermectin EC 2500 times, rapid culling EC 1000 times and so on.

When spraying, focus on the back of the branch, because the scale insect is mainly attached to the back of the branch.

Peaches are a delicious fruit, but what if the peach tree has worms?

Hawthorn red spider.

The hawthorn spider is also a common pest, it likes to breed in the area after June, and it is a pile of eggs for life, so how to kill it?

First of all, you need to apply more organic fertilizer to the tree, but avoid applying nitrogen fertilizer to improve the tolerance of the tree.

There is also the need to clean the orchard and scrape off the coarse bark on the main trunk and main branches, mainly to eliminate the overwintering female adult mites, otherwise they will lay eggs after the winter, and it will be difficult to kill at that time.

Peach aphid.

To kill peach aphids, you can choose natural enemy control, booby-trapping, and spraying insecticides.

Natural enemy control is to kill it with its natural enemies, the natural enemies of the peach aphid include but are not limited to: spiders, ladybugs, aphid flies, lacewings and so on. If you want to use natural enemies to prevent and control, you can put more natural enemies, this method is the simplest and most practical method.

Insecticides can also be used to kill peach aphids, but in the process of prevention and control, it is necessary to treat them and avoid the abuse of pesticides to protect natural enemies and give full play to the role of natural enemies in controlling aphids.

End tea winged bugs.

The methods of eradicating the tea-winged bug are: manual killing, fumigation, and egg removal.

Manual killing is mainly to kill the overwintering adults to prevent successful overwintering.

Smoking is to smoke them to death with the smoke released by burning wood chips, which is the simplest. The last type is egg removal, which is mainly to remove the eggs of the tea-winged bugs to prevent the birth of more tea-winged bugs.

The main insect pests of peach trees are peach buds, scale insects and red spiders, peach buds will cause curls in the leaves of the plant, and can be controlled with 1500 times of 80% dichlorvos emulsifiable concentrate; Scale insects will cause stunted plant development, and can be sprayed with 1000 times of scale bizhi solution for control; Spider mites can cause plant defoliation, which can be controlled by spraying 1000 times of 10% phenylpyridoxin emulsifiable concentrate.

Answer manual control: in the spring to start preparation, in the peach flowering season, in the orchard to place a yellow board in the orchard to trap fruit flies, is a good choice, in this season to get rid of a fruit fly, you can save a considerable number of peaches. After killing fruit flies, it is necessary to carry out bagging treatment, and after the pollination of peach blossoms is completed, it is necessary to set up for treatment, which is the most effective means of preventing and controlling fruit flies, but not only the larvae of fruit flies can harm peaches, and the adults of fruit flies can also cause great harm to peaches, so they should be carried out with pesticide control.

In the fruit expansion period of peaches, you can spray fly amine plus avermectin plus chlorantraniliprole for control, this method can not only effectively kill fruit flies, but also have a good effect on common heartworms. If it has been harmed by fruit flies and heartworms, the infested fruit should be removed in time, patrolled in the peach orchard before the larvae are removed, and the insects and fruits should be removed in time, and the larvae should be killed, and the control group will continue to expand, and the pest population will be controlled at the density of the diseased group, so that it will not be able to cause harm to the peach.

There are white bugs in the stems of the peach tree, which are the larvae of the red-necked longhorn beetle. Peach tree red-necked longhorn beetle control method:

1.Adult worms are caught manually. During the period of 6 and July, the adults are at their peak and can be captured manually.

Hook a long bamboo pole with an iron hook to the branch and shake it vigorously, and the pests will fall to the ground one by one and catch them one by one. Manual capture is fast, effective, labor-saving, drug-saving, and does not pollute the environment. After the pupa of the pupa is feathered, during the adult activity in June and July, the habit of the adult having resting branches from noon to 3 p.m. can be used to organize personnel to capture in the orchard, which can achieve better control results.

2.Whiten the main branches. 4 During May, i.e. before the adult emerges, the trunk and main branches can be coated with a "white coat".

Crack and void in the bark to prevent the adult from laying eggs. Taking advantage of the habit of being afraid of white, the main trunk and main branches of the peach tree were painted white before the occurrence of adults, so that the adults did not dare to stay on the main trunk and main branches to lay eggs. Whitening agent can be used quicklime, sulfur, water, press 10:

1:40 ratio for preparation; It is also possible to coat the branches with the sediment of the stone sulfur mixture of the year.

3.Kill S. in advanceLarvae.

The larvae hatched before September are eaten under the bark, and at this time, they can look for fine reddish-brown insect droppings on the main trunk and main branches, and once they find insect droppings, they use a sharp knife to cut the bark to kill the larvae. Branches can also be inspected in the spring of the following year, and once reddish-brown sawdust-like droppings are found on the branches, the larvae in the xylem can be dug out with a sharp knife to kill S.

4.Methods of drug prevention and control. Depending on the growth period of the pest, different methods are taken.

During the peak stage of adult occurrence and the larvae just hatching in 6 July, spray 1000 times of 50% borer pine emulsifiable concentrate or 10% imidacloprid 2000 times on the tree body, 7 10 days 1 time, spray several times. or wormhole application. Older larvae have bored into the xylem, and spraying has no effect on them, and can be treated by wormhole application.

Clean the fecal hole on the trunk, fill the hole with dichlorvos tampon, use a disposable medical syringe, and pour 50% dichlorvos 800 times or 10% imidacloprid 2000 times into the cavity, and then seal the orifice with mud.
