Now that the peach blossoms have just fallen, there are small fruits and aphids, what medicine is go

Before the budding of peach trees in spring, before and after the flowering period are the times when pests and diseases often occur, especially the control before germination is the most critical. When to spray the peach tree. In March and April, the temperature slowly rises, germs and pests begin to move, at this time, it is necessary to seize the time to spray and control, which can reduce the incidence of pests throughout the year.

Because peach tree flowers are particularly sensitive to pesticides, spraying fungicides is very prone to pesticide damage, so it must be used before or after flowering.

After the peach tree falls flower, it can be sprayed with 10% imidacloprid 3000 times + 25% carbendazim 600 times, which can control aphids, heartworms, etc., and for apple leaf curl moth, 25% chlorpyramide No. 3 1500 times can be sprayed 7-10 days after flowering, the two agents can be used in rotation, and the peach trees with more serious conditions can be sprayed 2 times.

Before the peach tree sprouts, the orchard is sprayed with a new high-fat film to prevent virus replication, infection, and rot.

Before the peach tree blooms, timely prevention and control of pests and diseases. In the event of glue flow, the glue stain should be scraped off in time, and then the mother liquor of the tree protector should be brushed, which can destroy the pectin synthesis in the tree, inhibit the production of glue stain and make the glue molecules hydrolyzed rapidly, which can lead to the flow of gum in fruit trees.

After the peach tree is gone, in addition to removing diseased leaves, dead leaves, hunting overwintering pests such as red-necked longhorn beetles, or plugging the wormholes with cotton soaked with dichlorvos. Then use some insecticides to thoroughly control pests, improve the resistance of fruit trees to diseases and pests, and improve the efficiency of photosynthesis.

There are many types of peach tree pests, but the main pests can achieve good results by using corresponding pesticides. Peach aphid: mineral oil emulsion, diesel emulsion, stone sulfur mixture, rapid culling, chlorphosphine, Compto, carbofuran, etc.

Peach Moth: Insect race to death, enemy killing, Saidan, Green Pepsi, A Killing, An Green Treasure, etc. Mulberry white scale:

Mineral oil emulsion, diesel emulsion, cometrein, phosphine, prochlorfen, eule, etc. A little leafhopper: quick culling, chlorphos, malathion, thiophos, insectoprid, afarin, etc.

Peach borer: kill thiophos, good labor, An Minle, An Lubao, insect race death, A killing spirit, enemy killing and so on.

Imidacloprid or emamectin benzoate (emamectin benzoate).

Therefore, the second medication is generally after the flowers have fallen, and the second medication is generally carried out after the peach blossoms have fallen to 80% at the end of the flowering period. It can be sprayed with 46% acetamidos, 2000 times of imidacloprid water dispersible granules, and 1500 times of Bacillus thuringiensis.

The peach tree has just had flower buds, and there are a lot of tooth worms found on the small flower buds, can pesticides be applied?

Hello, the answer is excellent for you: can be jujube banquet town to say, the temperature rises in spring, the eggs of the peach aphid wintering stool Luyin will germinate and hatch with the peach tree flower buds and leaf buds, and come out to harm the flower buds, and the best time for the first time to use the drug is carried out before the peach tree flower buds are red to 20%-30% of the flowers. The agent is 1000-1200 times of 70% imidacloprid and 1500 times of wild prick for spraying.

The second time of application: After the flowering period, the young leaves grow and develop, and generally after the leaves and branches are holed, the hatched peach aphid will be transferred to the leaves for feeding. Therefore, the second medication is generally after the flowers have fallen, and the second medication is generally carried out after the peach blossoms have fallen to 80% at the end of the flowering period.

It can be sprayed with 46% acetamidosis water dispersible granules, imidacloprid water dispersible granules 2000 times, and Sumeng large dry cloud imitation source Bacillus aureus 1500 times.

Generally, two doses are sufficient, but serious ones require three doses.

Summary. Pro, can be sprayed with imidacloprid, difenoconazole, avermectin and other chemical agents.

Pro, can be sprayed with imidacloprid, difenoconazole, avermectin and other chemical agents.

Peach trees are prone to peach buds, peach leaf miners, peach borers and other insect pests after fruiting, and should be sprayed with drugs in time for prevention and control. It can be sprayed with imidacloprid, difenoconazole, avermectin and other chemical agents. Not only that, but it is also susceptible to diseases, common diseases such as brown rot and anthracnose.

It is necessary to spray alumina in time to spray chlorothalonil or carbendazim to sterilize and disinfect, otherwise the deficiency will hinder the healthy growth of the fruit, reduce the yield, and affect the fruit beam cultivation and destruction of the product.

If there are aphids in the peach tree flowering, the following methods can be taken to control it:

1.Manual deworming: Use manual or cotton swabs to remove aphids from peach blossoms and directly eliminate aphids.

2.Pesticide spraying: You can use organic pesticides or chemical pesticides, dilute them according to the instructions and spray them on the peach blossoms to kill aphids.

3.Encourage parasitic natural enemies: introduce host natural enemies for breeding and establish the natural ecological balance of bed bug populations, so as to achieve the purpose of saving control costs and protecting the bright environment of the ecological ring.

4.Strengthen the disease resistance of peach trees: through reasonable fertilization, moderate watering, and maintaining soil air permeability, etc., so as to improve the resistance of peach trees and defend against aphids.

It should be noted that before carrying out any control measures, it is necessary to understand the varieties of peach trees, the types of pests and diseases, the growth season and other factors, and take reasonable and effective control measures in combination with the actual situation. In addition, when spraying pesticides, it is necessary to pay attention to dilution according to the concentration specified in the instructions, wear anti-baby protective clothing, and apply pesticides in the morning and evening when the wind is low and the temperature is low to prevent accidental injury.

Summary. Hello, the aphids on the peach tree are serious, the two insecticides of imidacloprid plus spiromethane ethyl ester<> these two should be used together, which can produce immediate effects, and spiromethane ethyl ester can also prolong the duration of the <> consultation record · on 2022-05-03

Hello, the aphids on the peach tree are serious, the two insecticides of imidacloprid and spiracil ethyl ester<> these two insecticides should be used together, which can produce immediate effects, spirafen ethyl ester can also extend the duration of effect<> imidacloprid can be sprayed with water about 2000 times <>

The common special drugs for fighting aphids are imidacloprid, acetamiprid, resveratrol, kung fu, bitter pine, thiamethoxam, clothianidin, endinotefurin, anti-aphid, pymetrozine, etc., pay attention to alternate use when using them to avoid resistance <>

Summary. Peach trees can be sprayed with gibberellin for flower and fruit set, and 1000 mg l should be sprayed once 15 to 20 days after flowering. It can also be sprayed with 15-20 mg l of p-chlorophenoxyacetic acid during flowering, and 25-40 mg l of p-chlorophenoxyacetic acid can be sprayed at a higher concentration during physiological fruit drop.

It can also be sprayed once after the full flowering period of 20mg l of naphthalene acetic acid solution, sprayed 5-10mg l before fruit coloring, and sprayed again after half a month.

Hello dear to you, I am very happy to answer the question of Bi state, the prevention and control of peach aphid stupid pesticides: mainly mineral oil emulsion, diesel emulsion, stone sulfur mixture, melt scale, rapid culling, chloride phosphorus, imidacloprid, aphid lice net, Kangfudo, Emele, Jin Haonian, good winter, anti-aphid, prothiocarbofuran, acetamiprid, Mobilang, etc.

After the peach tree is flowered, it can also be used to protect the flower and fruit, and boron can be applied, and the application method is: 1. Timely fertilization outside the root (foliar) during the flowering period and 15 days after flowering, borax 300 times. 2. Increase the application of organic fertilizer (after late August every year).

3. Combined with organic fertilizer, apply 2 kg of borax per mu of soil. After the peach tree is flowered, spray 1500-2000 times of the liquid of imidacloprid or acetamiprid to control aphids.

Peach trees can be sprayed with gibberellin for flower and fruit set, and 1000mg l should be sprayed once 15 to 20 days after flowering. It can also be sprayed with 15-20mg L of Tanling p-chlorophenoxyacetic acid during flowering, and 25-40mg L can be sprayed during the physiological fruit drop period to increase the concentration. It can also be sprayed once after the full flowering period of 20mg l of naphthalene acetic acid solution, sprayed 5-10mg l before fruit coloring, and sprayed again after half a month.

Prevent a large amount of fruit drop from peach sap trees. When planting, you can spray gibberellin on peach trees, and pesticides such as phenoxyacetic acid and naphthalene acetic acid are very good for fruit preservation.

The rough time of spraying pesticides on peach trees must be blind and reasonable, and we build a rock to spray gibberellin for it to prevent it when the peach tree enters the flowering period for about half a month, so that the effect of preventing and controlling fruit loss is better. Chlorophenoxyacetic acid should generally be used before flowering or after the peach tree has physiological fruit drop, so that the effect of fruit preservation is also very good. Naphthalene acetic acid is best used after the veraison period of peach tree fruits, which can also play a role in avoiding fruit falling.

I wish you a happy life and a happy <> every day

Don't hit when the flowers are at their peak, and play with phenylene ether when you're two-thirds of the way through.

Pest and disease control during peach tree flowering period.

When the buds are red, spray 1000 times of 20% wellgangmycin (1 sprayer to 15 ml).

After flowering, spray 1500 times of dichloride (1 sprayer to 10 ml), or 10% imidacloprid 1500 times (1 sprayer to 1 packet), or 48% Lesben 1000 times liquid (1 sprayer to 15 ml) + 70% methyl tobuzine 1000 times (1 sprayer to 1 small soil scoop), or 80% zebsen 600 times liquid (1 sprayer to 2 small soil scoops) + potassium dihydrogen phosphate solution (1 sprayer to 1 small soil scoop) +Urea (1 sprayer to 1 small soil scoop) to control aphids and other pests and diseases.

If there are aphids on the flowers, don't use pesticides, the non-toxic and environmental protection effect made by yourself is good, and it is worth learning.
