What medicine is used for medicination after apple flowering?

What medicine to apply after the apple flowers fall should be decided according to the specific situation of the occurrence of pests and diseases in the orchard.

If the pre-flowering prevention is timely, there are no particularly prominent pests and diseases over the years, the first medicine after flowering is generally 7-10 days after flowering, but adjustments should be made for individual pests and diseases.

The main pests and diseases of the flowering orchard are powdery mildew, red star disease, red spot disease, black spot disease, mildew disease, spot defoliation disease, brown spot, anthracnose leaf blight, ring disease, anthracnose, dry rot disease and other diseases. The main insect pests are red spiders, aphids, small leaf roller moths, cotton aphids, scale insects, goldenrod moths, golden caterpillars, beetles, green blind bugs, etc. This stage is the peak period of various pests and diseases, at this time the spraying should be both pests and diseases, spraying must be sprayed evenly and sprayed thoroughly, no leakage spraying and no re-spraying.

If there is rainfall after flowering, the spore disc of apple powdery mildew, rust, bagging black spot disease, and early defoliation will absorb water and expand, and after breaking, the spores will spread or splash on the young fruit and young leaf skin pores with air flow or natural rainfall, that is, the initial infection will be caused to the young fruit and leaf surface. If the spray is not sprayed, it will be sprayed quickly, otherwise the germs will form a primary infection after the rain, and it will not play a role in protecting before the rain. The incubation period after the invasion of apple powdery mildew and rust is very short, with 6 120 days for brown spot disease, 7 100 days for black spot disease, and 15 150 days for fruit rot disease.

At the same time, the larvae of the leaf-curling moth began to damage 7 to 10 days after the apple flowering, and the aphids that hatched from the overwintering eggs also began to damage the young shoots, shoots and leaves. It can be seen that it is very important to take medication 3 to 7 days after flowering.

1) Focus on powdery mildew: avezole difenolate (avirovololate) + ether ester (or methylthioetherphenol or phenylether methiosulfide) + emamectin benzoate (or matrine) + calcium sugar alcohol (or calcium ammonium nitrate), which can be sprayed after flowering.

2) Focus on mildew heart disease: polyantimycin (or pyrazoledesen combination) + matrine + sugar alcohol boron, 80% of the flowers can be sprayed.

3) Focus on red spider: avezole difen (aviroproxil or thiobenone or ethidazole) + pyraclostrobin (or methiopentazole or tebuconazole propyl zinc) + emamectin salt (or matrine or avermectin) + calcium sugar alcohol (or calcium ammonium nitrate), spray 7 days after flowering.

4) Focus on pear heartworm: avezole dixil + pyraclostrobin (or methioconazole or tebuconazole propyl zinc) + emamectin chlorpyramide + calcium sugar alcohol (or calcium ammonium nitrate), you can spray after flowering.

5) Normal control: avezole dixil (averofenolate or thiobenone or ethidazole) + pyraclostrobin (or methioconazole or tebuconazole propyl zinc) + emamectin salt (or matrine or avermectin) + calcium sugar alcohol (or calcium ammonium nitrate), spray 7-10 days after flowering.

I don't know much about this, but you can go to a professional place for consultation. Their method works very well.

When the apple tree is in the pre-flowering period, in order to prevent pests and diseases, you can apply some stone sulfur mixture on the plant, and then add some of the general of the tree protection solution, in the early flowering period to spray thin urea, sucrose water and melon fruit Zhuang Tiling mixture, in order to promote flowering and fruiting, after flowering to use thin Bordeaux liquid for spraying control.

1. Early flowering

Apple trees in the flowering period to play some reasonable liquid, in order to promote the flowering and fruiting of the plant, so what kind of medicine to apply in the flowering period of apple trees, in the early flowering period to spray thin urea, sucrose water and melon fruit to the plant according to the growth of the plant, in order to improve the fruit setting rate and the growth of the plant, and then according to the flowering situation appropriate to apply a best.

2. Before flowering

Apple trees are easy to suffer from red spiders, star caterpillars and other hazards before flowering, it is best to observe the growth of the plant during the growth period after the end of winter pruning, when the disease is found, it is necessary to apply some stone sulfur in time, and then add some of the general medicine of the tree guard, apply it once every half month, in order to kill the bacteria.

3. Hand grinding during the full flowering period

When the apple tree enters the full flowering period, in order to ensure the number of flowers and fruits, it is best to spray before the rainy season comes, mainly spraying thin lime multi-volume Bordeaux solution and melon fruit strong Tilling solution on the plant, and spraying an appropriate amount of carbendazim solution for prevention and control in the later stage, so as to have the best anti-disease effect.

4. After flowering

Generally, apple trees are easy to cause spotted defoliation disease after flowering, mainly in autumn, it is best to continuously spray thin promethanein wettable powder and melon fruit strong tiling solution after flowering, and at the same time add an appropriate amount of Bordeaux liquid for spraying, in addition to pruning, in order to eliminate the source of disease.

The main medicine for <> apple trees is Bordeaux sap, which can kill bacteria and insects, and is less toxic and conducive to the growth of apple trees. Apple trees in the dormant and flowering stages need to be sprayed with insecticides and herbicides to control pests and diseases. After fruiting, the apple tree needs to be sprayed with Bordeaux liquid, which can prevent anthracnose, defoliation, etc., avoid apple infection, and make the fruit grow rapidly.

Pesticides should not be used when the apple tree is in bloom.

During the flowering period, it can not be sprayed, and it can be sprayed before and after flowering. Apples cannot be sprayed during the flowering period. Do not affect apple pollination. Apple trees cannot be sprayed with pesticides during the flowering period, because the insects need to be pollinated during the apple flowering period, and spraying pesticides may kill the insects.

The main drugs used by apple trees before flowering are DuPont Fuxing solution, 200 kg of water per 25 ml of liquid medicine, sprayed on 1 acre of land, which can treat early bacteria such as rot bacteria, ring pattern bacteria, moldy heart bacteria, and defoliation bacteria. And every 200 ml of liquid medicine mixed with 400 kg of water, can be sprayed on 2 acres of land to treat red spider larvae and their eggs.

Many friends who plant apple trees should want to know what medicine to take before the apple tree blooms. The first thing you need to know is that apple trees usually suffer from pests and diseases such as rot fungus, ring pattern fungus, mildew fungus, defoliation fungus, powdery mildew, anthracnose, spider mites, borrowing leaf rollers, and goldenrod moths before and during flowering.

The drugs used in these pests and diseases include DuPont Fuxing, 5% Nisolan EC, chlorpyrifos, 70% methyl tobuzin solution, 10% Polyann 1500 times solution, 50% carbendazim solution, 48% Lesben, Nongdile, 5% imidacloprid, avermectin, 20% pyridoxalin and other drug solutions.

But at this time, the focus of disease prevention and control is mainly on the elimination of rot bacteria, ring pattern bacteria, mildew fungus, defoliation bacteria and other early bacteria, ** these bacteria, you can use the more rain-resistant DuPont Fuxing solution, 200 kg of water per 25 ml of liquid medicine, can be sprayed on one acre of land.

The main insect pests are red spider larvae and their eggs, you can use a concentration of 5% Nisolan EC, 400 kg of water per 200 ml of liquid medicine, can be sprayed 2 acres of land, and when controlling effective moths such as drill-hearted leaf roller and golden-veined fine moth, you can use 250 ml of chlorpyrifos mixed with 400 kg of water to spray 2 acres of land.

In general, in general, the apple spring spraying prodrug of the lifting and infiltration cover time, choose the right choice in the apple flowers just show red to the inflorescence separation period (although the buds are red but the flowers are still tightly clustered together without blooming) The comprehensive effect of spraying is the best, on the one hand, at this time the pathogen pests have been exposed to the activity is easy to be killed by the drug, on the other hand, the flowers and buds of the fruit tree have not yet been fully exposed and opened, you can appropriately increase the concentration of pesticides when the drug is used to control pests and diseases, and it is not easy to spray the young leaves of the fruit tree, The young flowers cause pesticide damage or produce other adverse negative effects.

Hello dear ha, very happy to answer for you! Can you use sterilization medicine when apples are bloomingIs it not recommended to use sterilization drugs when apples are flowering, as this may adversely affect pollen and insects, and may even lead to deformed fruit staring or poor storage. If you need to control pests and diseases, you can choose to use low-toxicity, high-efficiency and environmentally friendly Nongchunfeng medicine, and use it in accordance with the instructions for use and safe operation procedures.

At the same time, it can also strengthen the management of apple trees, improve their immunity, and prevent the occurrence of pests and diseases.

Generally speaking, apples do not need to be pesticides before fruit setting after flowering, but in the case of rainfall during the flowering period, it is necessary to spray the apple tree, and the rain during the apple flowering period will lead to the occurrence of some diseases, mainly the mildew of apples. This disease usually causes damage mainly through the stamens of apples. This kind of harm will not show symptoms at the beginning, and in the later stage of apple growth, when it is close to ripeness, the fruit surface will turn yellow, the inside of the fruit will be moldy and rotten, and the fruit will fall off in advance, and it can rot from the inside to the surface in serious cases.

The occurrence of this change, there are certain requirements for humidity, in the case of rain in the flowering period of Qi Prefecture, it is conducive to the spread of germs, so we encounter the situation of rainfall in the flowering period after the apple flowering, we must take certain measures to prevent and control mildew heart disease, the best measure is to spray, after the rain stops, the apple tree is sprayed with fungicide, it can play a good role, but we should note that many fruit farmers now pollinate apple trees, are pollinated by quiet bees. We should pay attention when we apply pesticides. To choose some safe spike bend high powder, to avoid affecting the wall bee technique, generally speaking, we at this time generally use polyantimycin.

Now let's talk about the problem of fruit drop, there are many reasons that will cause apple drop, such as apple varieties. The ** of apple buds, the weather during the flowering period and other conditions may cause the phenomenon of apple fruit dropping.

Summary. Before the apple tree blooms, you can hit DuPont Fuxing solution, spray 1 acre of land with 200 kg of water per 25 ml of liquid medicine, which can prevent and control early pathogens such as rot germs, wheel pattern bacteria, mildew fungus, and defoliant bacteria, and every 200 ml of liquid medicine mixed with water 400 kg can be sprayed on 2 acres of land, which can control red spider larvae and their eggs, and can also use 5% Nisolan EC, chlorpyrifos, 70% methyl tobuzin solution and other medicinal solutions when controlling these pests and diseases. ”
