Eggplant root rot and dead tree rate is high, how to prevent it?

Eggplant root rot and dead tree rate is high, how to prevent it? Bacteria can hide in plants and survive for more than two years. The routes of transmission are varied, mainly from the plant epidermis and wounds.

Under the right conditions, bacteria can spread through wind and rain through conidia and continue to invade healthy plants. This vicious circle has led to an epidemic. It is even more rampant when the humidity is high.

It spreads and is extremely harmful. Common causes of root rot are long-term immersion of the roots in water or invasion by bacteria. The rot of the roots can affect the growth of all eggplants and even die.

This is a fungal disease, a type of eggplant, which can be brown eggplant spot (also known as ring rot), which is very harmful to the normal growth of eggplant. At this point there are many diseases, such as ring rot, brown star disease, and spot disease, which are often difficult to distinguish. These scum diseases are fungal diseases that tend to occur under high temperature and humidity conditions.

If it is easy to occur after or after rain, these diseases are sudden and **, and may infect the entire shed overnight.

The eggplant may be a dead tree because of nutrient deficiencies and many diseases. I suggest you take a look at the root system of the eggplant. If the root system is not good, it will further affect the growth of the eggplant.

It can effectively reduce the occurrence of pests and diseases and root system, and strengthen seedlings. During the growth period, the amino acid boron calcium leaf fertilizer is crushed many times, which effectively replenishes nutrients, greatly reduces the possibility of eggplant death, and improves quality and performance.

Before the rainy season, clean the drainage ditch and drain it in time after the rain so as not to make the soil moisture even. In the hot summer, immediately after the rainstorm at noon, water with well water to reduce the temperature of the field; Remove diseased, yellow and old leaves from the bottom of plants in a timely manner, and improve ventilation and propagation conditions between facilities; After the rain, harvest the eggplant madura in time, pay attention to the removal of diseased fruits, rotten fruits, and diseased plants, and bury them deeply. Do not soil and compost to reduce sources of reinfection.

When the disease is severe, it must be controlled by spraying drugs. Red wave eggplants need to bloom the day before or on the same day. It is better not to bloom after the eggplant flowers are fully opened, and the concentration of the flowers should be reduced when the temperature rises, otherwise it will cause the eggplant fruit to crack.

You should choose some pesticides, or check the soil condition, and then do it according to the specific method.

Some drugs can be used to prevent and control, and at the same time, you can also understand the specific cause of decay, or use some fertilizers**.

It is necessary to choose eggplants of good varieties for planting, to ensure the humidity of the soil, to water in time, to ventilate in time, and to pay attention to the density of planting.

Crop rotation, soil disinfection, and proper fertilization.

Control methods of eggplant root rot.

1. Crop rotation suitable for rotation stubble planting can play a good role in the prevention of root rot, such as crop rotation with cruciferous and lily crops, or rotation with some field crops for 3-5 years, and then planting eggplant, the occurrence of root rot will be well controlled.

2. Soil disinfectionIf the root rot of the plot is more serious, and you do not want to rotate, when planting eggplant, disinfect the soil in advance.

3. Reasonable fertilization In addition to the nitrogen fertilizer necessary for the growth of eggplant, we should also pay attention to the use of phosphate fertilizer and potassium fertilizer.

4. Remove the diseased residues after the eggplant harvest and before the eggplant planting in the second year, the diseased and residual bodies in the field should be cleaned up in time, especially the plots where root rot occurs, when the eggplant is ripe and harvested, the diseased residues falling in the field should be cleaned out of the field in time, so as to reduce the wintering place and reduce the number of pathogens in the field.

5. Reduce woundsWhen carrying out agricultural activities in the field, it is necessary to pay attention not to cause damage to roots and stems, and avoid wounds on plants, so as to reduce the infection of root rot and play a preventive role.

6. In the early stage of the disease, the roots are irrigated with the medicinal solution, generally each plant is irrigated with a liter of medicinal solution, irrigated once every 7 10 days, and irrigated 2 or 3 times continuously. Agents available: 50% carbendazim wettable powder 500 times liquid, or 50% benmonatelim wettable powder 800 times liquid, or 50% dimethylbenbenyl wettable powder 500 800 times liquid, or copper sulfate 2000 times liquid, etc.

Eggplant root rot is a soil-borne disease, its pathogen survives in the soil for a long time, under normal circumstances, can survive for 5-10 years, it can be said to be a very stubborn soil-borne disease, after planting, the use of strong rooting agent Hao Wanjia ** to promote rooting and strong roots, it is a new type of comprehensive, broad-spectrum rapid killing of soil-borne diseases of soil disinfection preparations.

What causes rotten roots in eggplants?

Hello Kiss, eggplant root rot mainly occurs in the seedling stage, adult plant laughing cultivation stage, mainly caused by physiological diseases and soil-borne diseases. The main reasons for eggplant root rot are low temperature and high humidity. After rain or irrigation, the root system is soaked in water for a long time, and the root absorption capacity is poor; Soil-borne diseases such as root rot, soft rot, and wilt.

In this case, we can choose to pull out the eggplant seedlings directly, and we can also choose to use some antibacterial and insect removal drugs, and then water less.

It is necessary to remove diseased plants, spray pesticides in time, pay attention to control soil moisture, and ventilate in time.

You can use antibacterial and insect control drugs, water less, and you should also pay attention to the state of the eggplant at ordinary times, and you can also choose to pull out the seedlings directly.

Summary. You can only change the soil, or enter the water to disinfect the soil, and use the fungicide.

You can only change the soil, or enter the water to disinfect the soil, and use the fungicide.

It is said to work. Is there any other way?

That can only be a change of soil.

Now how to find a way to control the spread.

At the onset of the disease, 40 roots of putrid 1000 times liquid can be sprayed or watered with the diseased plants; or 8 0 of 402 EC 1500 times liquid irrigation roots.

It can be used with high-efficiency fungicides to sell 1000 times of Liangzhile Zhongmin + 300 times of Pliden fish protein to dip the root; For the eggplant that is currently suffering from root key shirt rot, the watering should be reduced and the roots should be irrigated 1 2 times in a row.

You can also buy Oxamyl Formabi.

Well, I'll try it tomorrow.

Eggplant does not require much water in the early growth stage, and appropriate drought is conducive to flower bud differentiation and fruit setting rate. After the root eggplant sits on the fruit, the water required for plant growth gradually increases, and the soil should be kept moist and properly drained and irrigated.

Eggplant has a strong growth momentum, many side branches, and leaves grow quickly, especially when the temperature is right and fertilizer is sufficient, the plant is more luxuriant. However, if the plant grows too densely, it will cause flower drop, rotten fruit, and poor fruit color. Therefore, trimming the leaves of eggplant can increase the yield.

Leaf pruning should remove weak branches and side branches at the base, as well as old leaves and diseased leaves, and appropriately remove overly dense healthy leaves to keep the leaves sparse and even, so as to facilitate ventilation and light transmission. During the whole growth period of eggplant, prune the leaves 4-5 times to prevent too many leaves from being pruned at one time and only a few leaflets on the top.

About 15 days after the eggplant seedlings were planted, shallow tillage and weeding were carried out, combined with small soil and thin application of seedling fertilizer once, and 10-20 quintals of thin human manure per mu. After the root eggplant sets fruit, remove the side branches below the root eggplant to avoid too many branches and leaves and consume nutrients. During this period, the plants have not been sealed, and deep cultivation and weeding, soil cultivation, a top dressing is applied, and 50 kg of potassium sulfate compound fertilizer is applied per mu.

When the plant grows into the middle and late stages, fertilizer should be applied once for each 2 harvests, and 15-20 kg of compound fertilizer should be applied per mu. At the same time, foliar fertilizers such as ribery, Yanwo powder, potassium dihydrogen phosphate can be sprayed.

Eggplant root rot is a soil-borne disease, some farmers react, home-grown eggplant, root rot occurs more seriously, affecting the normal growth, this content, will introduce to you in detail the symptoms, occurrence rules and prevention and control measures of eggplant root rot.

Soil-borne diseases such as root rot should be prevented, and the main preventive measures are as follows:

1. Crop rotation. Suitable crop rotation stubble planting can play a good role in the prevention of root rot, such as crop rotation with cruciferous and lily crops, or rotation with some field crops for 3-5 years, and then planting eggplant, the occurrence of root rot will be well controlled.

2. Soil disinfection.

If the root rot of the plot is more serious and you do not want to rotate, disinfect the soil in advance when planting eggplant.

3. Reasonable fertilization.

In addition to the nitrogen fertilizer necessary for the growth of eggplant, we should also pay attention to the use of phosphate fertilizer and potassium fertilizer, and at the same time, combined with well-rotted farmhouse fertilizer, comprehensive and reasonable fertilization in various aspects, can also prevent the occurrence of some root rot.

4. Remove the sick and disabled.

After the eggplant harvest and before the second year of eggplant planting, the disease and residue in the field should be cleaned up in time, especially the plot where root rot occurs, when the eggplant is mature and harvested, the disease and residue falling from the field should be cleaned out of the field in time, so as to reduce the wintering place and reduce the number of pathogens in the field.

5. Reduce wounds.

When carrying out agricultural activities in the field, it is necessary to be careful not to cause damage to the roots and stems, and avoid wounds on the plants, so as to reduce the infection of root rot and play a preventive role.

6. If root rot has occurred, it is necessary to spray pesticides in time to prevent and control (root irrigation can also be used), and common pesticides can be used to irrigate roots with dry agricultural roots.

Eggplant root rotten causes:

Eggplant has high requirements for temperature and light, and eggplant will grow quickly in a high temperature environment, but with high temperature, eggplant must keep the soil moist, and not let the surface water too much, otherwise there will be root rot in the reaction of vegetable farmers.

In fact, root rot is not entirely caused by water flooding the rhizome of the eggplant, and there are many comprehensive reasons. For example, there are a lot of bacteria in the soil, and many farmers grow vegetables in small vegetable gardens, so there will be some soft rot bacteria in the soil. The bacterium may not be particularly noticeable in normal times, but it can break out in the fall.

The cause of soft rot is also caused by the humid air and unclean soil, especially when planting eggplant in greenhouses, the temperature difference between inside and outside will make the dew in the shed condense more and more, and the air in the shed is too humid to cause the problem of eggplant rotten roots and leaves.

Analysis of the causes of root rot and control and management methods of eggplant.

Eggplant root rot control method:

Faced with the problem of rotten roots of eggplant, first of all, vegetable farmers must control the temperature in the greenhouse, because the dew is because after the humidity reaches a certain temperature, the moisture in the air will condense and become dew. That is, the temperature difference between noon and night is too different, so at night, we should also pay attention to adding a warm device to the surface of the greenhouse, so that the cold air outside and the temperature in the greenhouse are not too different.

The effective method can be to cover the outside of the greenhouse with cotton cloth and quilt and heat absorbing plate, and it can also be properly ventilated at night so that the moisture content in the air is not too high.

Root rot is usually caused by excessive water accumulation and infection with germs. Or fertilize too thick and burn the roots. If there is too much water, as long as you drain the water in time and spray pesticides, it will get better quickly. If it is too thick to fertilize the roots. It's not easy to do.

If the eggplant is rotten, you can bury it in the ground and let it grow new buds, or you can throw it away.

<> eggplant suffers from Verticillium wilt: irrigate the roots with amino-oligosaccharide aqueous agent (200-300 times the solution) and other drugs, and each plant can be irrigated with 100-150 ml of medicinal solution. Eggplant suffers from stem base rot:

Spray with 64% alum wettable powder (600-800 times liquid % oxafen wettable powder (800 times liquid) and other drugs. Eggplant suffers from root rot: root irrigation is carried out with drugs such as 50% carbendazim wettable powder.

1. Died due to Verticillium wilt

1. Symptoms: The edges and veins of the leaves of the eggplant begin to fade green and turn yellow, and then gradually spread to the whole leaf, and the diffusion trend is generally from bottom to top, and finally lead to the death of the whole tree.

2. Treatment method: In the early stage of the disease, use amino-oligosaccharides aqueous agent (200-300 times liquid) to irrigate the roots, 100-150 ml of medicine per plant, 1 time every 7-10 days, and 3 times in a row.

2. Dead trees due to stem base rot

1. Symptoms: There is no obvious lesion on the outside of the stem base at first, and after a period of time, the cortex at the base of the stem will gradually turn dark brown, and the diseased part will lose moisture and become dry after about 1 week.

2. Treatment method: spray with 30% oxazine wettable powder (800 times liquid) or 64% alum wettable powder (600-800 times liquid % methyl tobuzin wettable powder (1000 times liquid) + 50% carbendazim wettable powder (800 times liquid) and other drugs.

3. Dead trees due to root rot

1. Symptoms: The epidermis of the roots and stem bases of the plant is brown, and the epidermis of the primary roots or branches of the roots also begins to brown, and after a period of time, the cortex of the root system is destroyed or begins to rot, and the capillary roots also begin to rot.

2. Treatment method: In the early stage of the disease, use 50% carbendazim wettable powder and other drugs to irrigate the roots, 250-300 grams of medicine per plant, 1 time every 7-10 days, and 2-3 times with cluster irrigation.
