If the planted toon has a blight, can it still be remedied with medicine?

Due to the low temperature, rainy weather, and low sunlight, it is easy to develop blight. Our local early rice seedlings have to encounter several cold weather every year, the temperature plummets, every year there are several seedlings blight, the light can prevent the seedlings can be relieved, the temperature is abnormal and the temperature rises and falls sharply after the rainy day will cause mildew in the roots of the seedlings, and then cause the stems and leaves to yellow, wilt, the leaves are stretched but not expanded, this is the blight. This disease is very harmful, and if it is not treated in time, it will affect the growth of seedlings in the entire seedbed.

When the rotten seedlings often occur in the area or the seedling field, the disease field is generally sprayed before the soil or after the film is removed after the fall of the valley for prevention, the disease field should be treated with pesticides, and the disease center will be dug up and sprayed for prevention and control in a timely manner, and the agent can be used with 45% methyl frost Fumei double wettable powder 30-40 grams per seedling field.

<> rice blight mainly occurs at the seedling stage, and rarely occurs after transplanting and planting. Moreover, rice seedling raising is an important link in rice production, which determines the annual production and income of rice farmers, and it is very important to raise strong rice seedlings free of diseases and pests and diseases. Standing blight is a soil-borne disease, its pathogens are widely present in the soil, and the seedling growth is weak, the quality is poor, and the disease resistance is not strong, which is the main reason for the occurrence of blight.

The larvae eat the bark of the tree, and there are sawdust visible on the outside, burrow into the wood, and then open upwards to eat, and the hole is filled with sawdust, and there are fecal holes to discharge. In May, the adults fly out and eat the twigs and bark.

Rice blight can be infected by a variety of soil pathogens when the temperature and humidity are suitable, so the first spraying prevention in production is the most economical and effective, and it is also one of the most critical periods for the prevention and control of blight, that is, it can usually be sprayed before the soil cover after the rice falls, and whether the nutrients in the seedbed are sufficient and whether the ventilation is sufficient are the key to the occurrence of the blight. This is the period when the blight is most likely to occur. Therefore, it is necessary to carry out the prevention and control of blight at the weaning stage.

Yes, in fact, all kinds of plant conditions can be prevented in advance, and problems can be solved in time and remedied.

You can still use medicine to remedy, you can go to the farmer's market store and buy some suitable medicine to remedy.

Of course, it can be remedied, this disease is caused by a fungal infection, which can be carried out with carbendazim solution**.

Bark shedding: A large area of bark is shed, and the main trunk is damaged, causing the entire toon tree trunk to die. Poor management:

The temperature in winter is too low, and the warming protection is not in place; During the rainy season, there was a lot of rainfall, and the water was not drained in time, resulting in the drowning of the trees. Severe disease: Toon trees suffer from leaf litter, which causes root and leaf rot and eventually death.

Chemical pollution: Excessive fertilization and spraying cause serious chemical pollution of soil and plants, and then the branches and leaves dry up and die.

The bark of the toon tree is shed in a large area, and when the main trunk of the tree is damaged, the entire toon tree often dies. The bark of the toon tree is like a human coat, once it loses the protection of the outer bark, it will affect the growth and development of the plant, if the bark is missing too large, it will seriously affect the normal growth of the toon tree, and even cause the death of the plant.

Because of the poor growth environment and poor management, the roots of the toon tree die, resulting in the death of the entire trunk. In winter, the temperature is too low and there is no warming protection, and the weather is too cold, and the toon trees are damaged by low temperature frost. In the rainy season, there was a lot of precipitation, and the ditch was not dug in time to drain the water, so that the roots of the toon tree were soaked in water for a long time, and finally the toon tree drowned due to excessive rain.

The root rot of toon trees at the seedling stage is usually manifested as bud rot and branch wilting, and after the growth period, it is manifested as rhizome and leaf rot, and the damaged parts become ochre brown, and then gradually turn black-brown, and then begin to suppurate and rot. The mild ones are stunted, dry and fallen leaves, and the severe ones die directly.

Chemical contamination of the soil in which the toon tree is planted or the toon tree itself can cause the branches to dry up and die. Excessive fertilization can easily cause the soil to be contaminated with chemicals, so that toon trees planted on contaminated soil can also be affected. The toon tree itself is chemically contaminated, mainly by the overspraying of drugs.

Summary. Here's how to kill:1

You can dig a trench around the big tree, cut off the connected roots, and eat the young tree when it grows shoots, so that it can't grow. Slowly, the surrounding roots do not get nutrients and die. 2.

Can be scalded with boiling water 3Draw a circle on the main stem of the tree with a knife and peel off the bark, and within a few days the tree will slowly wither. This will kill the toon tree.

The killing methods are as follows:1You can dig a trench around the big tree, cut off the connected roots, and eat the young tree when it grows shoots, so that it can't grow.

Slowly, the surrounding roots do not get nutrients and die. 2.Can be scalded with boiling water 3

Use a knife to make a circle on the main stem of the tree, peel off the skin, and within a few days the tree will slowly destroy and wither. In this way, you can answer to kill the toon tree.

Cycloazinone is a systemic selective herbicide with low toxicity to humans and animals, and is relatively safe to use. It has a strong killing effect on the stinky tree and most other plants. Herbicides refer to pesticides that can completely or selectively cause weeds to grow and die, also known as herbicides, which are used to eliminate or inhibit the growth of plants.

How to kill the toon tree completely.

The way to make the incense talk about the rapid death of the tree is to either uproot it or pour some sulfuric acid into the roots of the tree. Peel the bottom of the toon tree and tear the bark open for a week so that the tree dies if it can't absorb water.

<> rice blight is divided into two types: physiological blight and pathological blight. The main cause of physiological blight is that the seedlings are unsuitable for soil pH, water, fertilizer, gas and heat conditions, and the symptoms of the disease appear, which are manifested as dwarfing, yellowing, few or no new roots, and the occurrence of light toon tree. The toon tree is said to be an angry tree, and if the person breaks the buds frequently, the toon tree will get angry and die.

<> is actually due to gluttony, which means that it needs a lot of nutrients every year to grow strong. The old farmer said that the dead animal carcasses should be buried in the roots in order to meet the nutritional needs of the toon tree, and the nutrient soil formed after mixing the seedling agent and the sieved fine soil. The seedling enhancer contains nutrients, fungicides, acid-regulating agents, insecticides and other components, and the main function of the acid-regulating agent is to ensure that the pH value of the nutrient soil can be presented in the pH range for a period of time.

The symptoms are poor growth of seedlings, brown lesions in the leaf sheaths, and gradual decay, and the roots appear brown and diseased, and the roots can be seen to be aging, yellow, russet, and seriously black and rotten.

The internal cause of red wilight is mainly potassium deficiency in rice plants, spraying 30 40 grams per seedling field with 10 kg of water for 30 40 grams per seedling field, increasing the dosage when seriously ill, and focusing on the use of drugs in the disease center. If the seedling field is dry, irrigation should be sufficient before using medicine, which can improve the control effect. The addition of Baohefeng, Onlibang, alginic acid foliar fertilizer or rooting agent spraying can promote the seedlings to be sprayed with potassium fertilizer, and it can also occur when it is light, the seedbed seedlings turn yellow, the disease center becomes a pot bottom yellowing, and the seedlings die in pieces when it is heavy; Pathological blight is a kind of disease caused by pathogenic fungal infection in the soil, which is manifested as rot, dwarfing and yellowing at the base of the seedling plant, and the root is easy to break when the plant is pulled by hand.

color, the leaves are curled, yellowed and withered, and finally brown wilts and dies. From the section of the bed and soil infected with the pathogen, the growth of some white or light red seedling roots can be clearly seen.

After the toon was unearthed, it was relatively young and tender, the stem was not lignified, and the germs spread in the neck, destroying the neck tissue, and the toon lodging. It can be mixed with the medicated agent pentachloronitrobenzene mixture, mixed with fine sand soil to form medicinal soil, which is used in the root neck.

Toon blight will make the leaves of the toon become yellow and yellow, and one by one dry wounds, and finally let the toon dry up and die, you can choose some pesticides to spray on the leaves of the toon, which can be prevented.

Its symptoms seem to be that there are many black dots on it that are prevented by pesticides, so it should be sprayed regularly, about twice a week, so that it can be effective.

The first leaf is very sparse, the second leaf does not grow much, the third leaf withers, and the fourth whole toon tree does not look very vigorous. Pesticides are sprayed before the toon tree has sprouted.

There are many people who like to eat toon scrambled eggs, and the dish of toon is also very delicious, so many farmers will also plant toon trees in the mountains. In this way, you can also make a good pick, and then you can also use it for stir-frying. However, some toon buds will also have fallen seedlings, which also makes farmers feel very worried.

Such a situation can also be well remedied, and if the remedy is timely, then it is also very good. <>

The reason why toon buds appear to fall is also because the seeds are very bad. There are many people who do not choose good seeds when choosing toon sprout seeds, which leads to some bad conditions in the process of planting toons. Sometimes it is easy to have some difficult problems, so it makes people feel very bad.

Therefore, when people plant toon buds, they should also choose fresh seeds, and cannot choose those seeds with pathogens, which is not conducive to the better development of toon buds. <>

If people find that the toon buds have fallen down, then they should be remedied in time. If the remediation is timely, then it is also a good way to reverse this phenomenon. Otherwise, it will also make the toon age very quickly, which is also very bad, and if it is serious, it will also cause a negative impact on the toon.

This is not conducive to its better growth, so people should also pay great attention to it, so that the toon can have a better growth process. <>

Toon is more delicious and deliciousNo matter what, everyone should also take a reasonable view of the development of toon. After all, toons are still very delicious, and many farmers are also very hard in the process of planting toons. If the situation of falling seedlings is found, then it is also necessary to find a solution according to the corresponding cause, so as to avoid some bad phenomena.

Otherwise, it will also make the toon seedlings appear in a bad state, which is also easy to lead to some negative effects on the toons planted by themselves.

This situation can be remedied. It is necessary to find out the cause of the phenomenon of toon buds falling in time, whether it is related to the amount of water and fertilizer watered or the temperature and light, and pay attention to preventing insect pests.

The main reason is that the soil is too wet, and if you add that the air humidity is also very high, this problem is easy to occur. If the air humidity is too high, you can strengthen ventilation to reduce air humidity, and if the soil moisture is too high, it is recommended to control watering to increase the exposure to light. Carry out the mulching of the seedbed or roots, sprinkle some fine dry soil, and reduce the surface humidity of the seedbed.

Then you can use some root promoters to promote the growth and development of the root system.

1.Disinfection of nursery sites. The seedling site is disinfected once a month with 84 disinfectant solution and potassium permanganate solution.

First close the doors and windows, spray the disinfectant on the ground or wall, and after 2 hours, open the doors and windows for ventilation. 2.Disinfection of seedling trays.

Each used seedling tray should be cleaned first, then soaked in potassium permanganate for 20 minutes, and then rinsed with clean water and dried. 3.Scientific species.

It is necessary to choose fresh seeds that are free of mildew, moth-eaten, full of particles, uniform in size, and have a germination rate of more than 95%. The seeds were rubbed to remove the wing membrane by hand, remove impurities, soaked in 1% formaldehyde solution for 20 minutes to sterilize and disinfect, and then soaked with 300 times the dilution solution of the sprout ecological treasure for 8-12 hours to inhibit the germs and miscellaneous bacteria in preparation for germination.

There are mainly beetle insect pests, moth insect pests, scale shell insect pests, etc. Dimethoate oxide emulsion can be used to kill longhorn larvae; In autumn and winter, the branches can be coated with lime, and in summer, emamectin benzoate can be sprayed on the branches; Scale-insect insect pests can be diluted with pyrethyl emulsifiable concentrate and sprayed.

Toon powdery mildew, toon cloud-spotted longhorn disease, mulberry yellow firefly leaf beetle; For powdery mildew, the use of chemical fertilizer should be increased, the ventilation and light transmission conditions should be improved, the diseased branches and leaves should be cleaned up in time, and the phosphorus fertilizer should be increased for the bottom fertilizer, and the excessive use of nitrogen fertilizer should be avoided during the growth period.

Avoid pickpocketing and avoid frost, and when there is a frosty climate, it is necessary to take corresponding precautions. When we plant papaya in our hometown, we will basically put some straw on the top of the papaya to avoid frost, because there is straw can play a good role in heat preservation, even if there is frost, it will condense on the straw, and will not condense on the papaya, after the frost weather, the papaya can still survive, but if the corresponding insulation measures are not done, the papaya will die, and the same is true for the dry blight of toon. <>

After loosening, it is easy to appear that the branches of some seedlings wither, in the case of relatively few, about 10%, if it is serious, then 80% will appear to disturb a dead branch on the imitation, which directly affects our planting efficiency.

Avoid planting, planting in the past, the past will also affect the occurrence of this disease. There is a pattern in its growth, if it is done late, for some numbers do not grow into full terminal buds, the temperature is low, then it is easy to frost damage, which will cause this disease. When we plant, we should choose to plant according to the local climate, not too late.

This disease is actually related to insufficient fertilizer and water management, and it is also prone to this situation. No matter what crops are planted, they need to be fertilized and managed, if the water is insufficient and the nutrients are insufficient, then it will be easy to yellow, the plant will be relatively small, and the disease resistance will be relatively poor, and it is easy to cause this disease.

Improper management is not done well, and ventilation and lighting are also easy to cause the disease. When they grow more lush, we need to prune them in time, and the planting can not be too dense, too dense will affect the ventilation and light, this problem is to pay attention to. <>

Finally, some pesticides can be used to control it. Of course, when using pesticides for control, if you find that some of them have dried up, then you should prune them in time, and then spray them with pesticides.
