What is the best medicine for peach tree blossoms?

After the peach tree falls into flowering, it mainly controls peach aphids, including beecloprid, pyrimetrozine, and other aphid killers with pyrethroid pesticides, and carbendazim and other sterilization.

Anthelmintic medicine will do. Generally, peach trees have this situation, and if you put some insect repellent medicine on the tree, it will slowly get better.

The peach tree is a small deciduous tree with ornamental flowers and juicy fruits, which can be eaten raw or made into preserved peaches, canned food, etc., and kernels can also be eaten. The flesh is white and yellow, there are many varieties of peaches, the general peel is hairy, and the skin of "nectarine" is smooth; The fruit of the "peach" is flat-disced; "Peach" is a peach tree for ornamental flowers, and there are various forms of petals. The gum secreted on the trunk, commonly known as peach gum, can be used as a binder, etc., as a kind of glycan, hydrolysis can produce arabinose, galactose, xylose, rhamnose, glucuronic acid, etc., edible, also for medicinal purposes, has the effect of breaking blood, and blood, and invigorating qi.

It is produced in China and widely cultivated in various provinces and regions. It is cultivated all over the world.

After the peach flowers have long leaves, the more serious ones are aphids, green blind bugs, leafhoppers, apple leaf moths and other hazards.

The time of spraying the peach tree should be accurate, the peach tree has 80% of the flowers, and the first time the medicine is used after the flowers are curled before the leaves are curled. Peach tree medicine should also be done "sterilization, aphid, insecticide, acaricide, fertilizer" five-in-one, after flowering to maturity 30 days, spray once every 15 days, must be sprayed carefully when using medicine, the condition or the machine is better.

There are many kinds of insect pests of peach trees, and the main ones are as follows: pesticides for the control of peach aphids: mainly mineral oil emulsions, diesel emulsions, stone sulfur mixtures, scale melters, etc.; Pesticides for the control of peach moth:

There are mainly insect race death, enemy killing, Saidan, green Pepsi, Azerin, etc.; Pesticides for the prevention and control of mulberry white scales: mainly mineral oil emulsion, cocofen, diesel emulsion, stone sulfur mixture, scale melting, phosphorus, rapid culling, chloride, Youlede, thiazinone, etc.; Pesticides for the prevention and control of peach leafhoppers: mainly rapid culling, killing phosphorus, malathion, etc.; Pesticides for the control of peach borer:

There are mainly thiophos, good labor, etc.

After the peach tree bears fruit, it is susceptible to pests and diseases, and if you want to prevent diseases such as brown rot, anthracnose and scab, you can spray fungicides such as carbendazim or chlorothalonil to prevent it. If you want to prevent insect pests such as peach leaf miner, peach aphid, tea wing bug and peach borer, you can spray imidacloprid, avermectin and difenoconazole and other agents for prevention.

The fruiting period of peach trees is between August and September, and peach trees need to be sprayed to prevent pests during the fruiting period, which can improve the yield of fruits. The pests that need to be prevented in peach trees are peach leaf miner moth, peach aphid, tea wing bug and peach borer, etc., and during the fruiting period, peach trees can be sprayed with chemical agents such as imidacloprid, avermectin and difenoconazole for prevention.

During the fruiting period, peach trees can be infected with brown rot, anthracnose and scabs. Brown rot can make peach trees stiff, anthracnose can make the fruit soft and rotten, and scabs will make the fruit black and rotten. During the fruiting period, peach trees can be sprayed with fungicides such as carbendazim or chlorothalonil for prevention, which is conducive to the healthy growth of fruits.

Before spraying peach trees, the agent can be diluted with water according to the instructions, and the concentration should not be too high. Spray the diluted agent on the branches and leaves of the peach tree, generally spray the peach tree once between 10 and 20 days, which can effectively prevent pests and diseases. If the peach tree has been diseased or infestation, the leaves of the peach tree need to be cut off and burned.

If there is a peach leaf miner moth on the peach tree, the peach tree can be sprayed with pyrethrin or pyrethrin for insect control, and if there are peach aphids on the branches and leaves, the peach tree can be sprayed with methamidophos or imidacloprid for insect control. If it is a tea-winged bug, it can be sprayed on the peach tree to kill the insects or Wanling, and if it is a peach borer, the peach trees can be sprayed with trichlorfon or quick killing to remove insects.

Peach trees should not be sprayed during the flowering period. It can be properly watered. It should not be watered, use flood irrigation. Because the flowering period involves the fruit setting of peach trees, if spraying or watering will affect the fruit yield, and in severe cases, it may be extinct. So you have to be cautious. In early spring, it is advisable to spray before the sap flows.

First, the peach tree spraying schedule.

When the flower buds of the peach tree are expanded, the stone sulfur mixture is sprayed; Before the peach tree flowering, spray cypermethrin + imidacloprid + carbendazim + active calcium + antifreeze + silicone; Potassium dihydrogen phosphate and true boron are sprayed once at the early flowering stage and the full flowering stage; After flowering, spray pymetrozine + cypermethrin + zeczeb + active calcium + active potassium + amino acid + organic silicon, spray 2-3 times; From June to August, at the beginning of the month, cypermethrin + dcaryl + avermectin + silicone, at the end of the month cypermethrin + zeb zinc + chlorpyrifos + silicone.

Extended information: 1. Tips for pollination of peach trees during flowering: The best effect is when the flowering period is concentrated and the pollination time is short.

1. Prepare coarse powder. Select the budding bell stall flowers in advance, beat the flowers with a simple powder machine, sieve them, put them in a humid absorbent place to dry them (more than 20 catties of fruit flowers can produce 1 kg of dry powder), wrap them in newspaper, and then wrap them tightly with a food bag, and put them in the refrigerator for later use.

2. Preparation of nutrient solution: 20 kg of water (the best in the sun), 1 kg of sugar, 25 grams of borax, a little urea.

3. When pollinating, take out about 250 grams of coarse dry powder, wrap it tightly with sand towels or silk stockings, put it in the nutrient solution and knead it repeatedly, and wait until the yellow powder is basically exhausted and the pollination solution is prepared.

4. Use a back sprayer, pay attention to the spray piece must be fine, and the fine mist should be out (if necessary, the spray piece should be self-made), and the spray should be dried from a high place to the point down. Each spraying pollination solution is not more than 2 hours, within 1 hour is the best, the prepared nutrient solution can be about 8 acres, generally pollinated for about 3 days, the time is after 10 o'clock in the morning and before 4 o'clock in the afternoon.

After five consecutive years of testing, it is particularly good for pollination of apple and peach trees, due to the strong vitality of flower pollen, the large amount of pollen used, and the concentration of time points, but the details of the operation must be strictly controlled.

2. What is the best medicine for peach tree flowers?

During the period after the peach tree falls into flower, some overwintering pests emerge one after another and begin to cause damage, such as pears, beetles, leafhoppers, leaf miners, caterpillars, etc. Some overwintering eggs have also begun to hatch, such as scale insects, pests, etc., and some germs have also begun to spread, such as peach brown rot, perforation, etc. There are also some peach aphids and peach powder aphids that have not been killed before flowering.

According to these pests and diseases that may occur after the peach tree flowering, it is necessary to consider that it is the peach tree fruit setting period, and the drug should be selected for insecticidal and sterilization broad-spectrum, efficient and safe, and will not cause pesticide damage to young fruits and do not affect the fruit.

Insecticides can choose some pyrethrins, such as deltamethrin, which can kill insects and aphids, and can also kill scales; Aphidicides can be used with imidacloprid, aphid mite, etc., acaricides can be used avermectin, pyridafen, etc., and fungicides can be mancozeb, metropia, chlorothalonil, etc. These drugs are all broad-spectrum drugs, one medicine is multi-purpose, and it is very good to take these drugs after the peach tree has fallen into flower.

In March and April, as the temperature gradually rises, germs and pests begin to move, so that the pest control of peach trees plays an important role in reducing the annual pest and disease base. Because peach trees are particularly sensitive to pesticides during the flowering period, spraying pesticides is very prone to pesticide damage, so spraying must be cautious.

Peach trees need to be sprayed with potassium dihydrogen phosphate and boron once at the beginning and full flowering stage, and pymetrozine, cypermethrin, zecze, vitality calcium, vitality potassium, etc. It should be noted that you must be careful with spraying during the flowering period, as improper use of pesticides can easily lead to flower drop, which will also affect the yield and quality of fruits. Therefore, it is more safe to use medicine before and after flowering, which is safer and safer.

Because peach trees have no leaves before flowering, many people generally manage them during the flowering period or after flowering, although many peach trees are not a problem with fruit set, but if there are more deformed fruits before flowering because of boron deficiency and calcium deficiency, then how do we manage it before flowering?

Although peaches do not have leaves before flowering, but the flower buds are present before flowering, at this time the flower buds are basically in a germination state, in addition to the root system, through foliar spraying to supplement nutrients, it can also promote the nutrition of flower buds**.

Of course, it is not just a foliar fertilizer, here it is recommended to use organic acid boron calcium foliar fertilizer, because this kind of foliar fertilizer can be absorbed through the phloem of the trunk and the flower bud plant, and then through the enzyme power promotion technology, to solve the problem of boron and calcium supplementation in flower buds, so as to promote the formation and pollination of flower organs, and improve fruit quality.

Hello, at present, in the production technology to improve the fruit setting rate of peach trees, the main use of gibberellin 920 and so on. It is generally used after flowering. To prevent low temperatures, you can use anti-pestifier to prevent frost damage. Plant webs.

Dear, hello, according to your question what medicine is best answered before peach tree flowering: it is best to use compound fertilizer before peach tree flowering, such as compound nitrogen fertilizer, compound phosphate fertilizer, compound potassium fertilizer, etc., as well as an appropriate amount of organic fertilizer, such as pig manure, sheep manure, etc., which can improve the nutrition of peach trees and promote the flowering of peach trees. The main diseases of peach trees are:

Sores, brown rot, anthracnose, perforation, branch rot, etc. The main insect pests of peach trees are: scale worm, walnut rot peach aphid, pear small, leaf roller insect, Tsubaki elephant, peach borer wax leakage, longhorn beetle, red spider and so on.

The choice of agent and spraying time is very important for the peach tree before and after flowering. 1. The pre-flower spraying is sporadic and a few flowers are the time to clear the garden! 2. The time of spraying after flowers is 80 to 90%, which is a good time for the first time after spraying.

chlorothalonil, stone sulfur mixture and other agents.

Peach trees can use paclobutrazol before flowering to inhibit the growth of new branches. Promote the differentiation of flower buds of the holding trip, so as to play the role of flower preservation. A stone sulfur mixture is also sprayed to kill pests that hibernate on the trunk of the tree, as well as aphids.

What medicine should be applied before the peach tree blooms, this should be determined according to the need. Disease prevention can be sprayed with stone sulfur mixture and chlorothalonil; Insect treatment can be sprayed with imidacloprid, thiamethoxam, etc.

After the peach blossoms in the spring, they will begin to grow young peaches, and the peach trees that grow well will also grow the entire branches, and the source of this belt needs to be pruned off at the time is the branches that do not hang the young peaches, as well as some branches that grow very densely, because this can better supply the nutrients of the whole tree to the young peaches and avoid being occupied by idle branches.

Precautions for peach tree planting:

If it is sown in autumn, it is best to use wet soil for ploughing, and can bury new shoots strictly, which is conducive to overwintering safety, fast growth of seedlings, and high survival rate. After spring sowing, it takes 7 to 10 days to pour two cups of water evenly.

When planting peach trees, consider whether there is frost during the flowering period, and plant peach trees in places where there is no frost hazard or where the frost risk is low. Frost is caused by radiative cooling or advection cooling. China's people have long had the experience of "snow under the high mountains and frost in the depressions".

In other words, low-lying areas are most affected by frost. Therefore, it is necessary to plant peach trees in places with smooth air, which is conducive to blocking the north wind, and the terrain is high.
