What are the common diseases of eggplant in the process of planting?

Eggplant belongs to the Solanaceae crop, and now is the season of a large number of market, the appearance of eggplant is very special, and the purple one is very beautiful! There are also many ways to eat eggplant, you can fry it, boil it and braise it! But my favorite is the eggplant with minced meat, it's delicious!

Diseases that often occur in the growth process of eggplant include root rot, verticillium wilt, bacterial wilt, gray mold, soft rot, bacterial brown spot, fruit rot, immune disease, powdery mildew, leaf mold, sclerotinia sclerotinia disease, virus disease, nematode disease and physiological diseases, such as poor coloration, flower drop, calcium deficiency and so on.

In the process of planting eggplant, the damage of aphids is a relatively common insect pest, and the adults and larvae of aphids feed on the sap of plants, harming the growth of crops. Moreover, aphids can also spread viruses, so once we find aphids, we must control them in time. Usually when spraying or using fertilizer, it is used together with biological bacteria selenium-rich fertilizer, which not only improves the disease resistance of eggplant, but also uses biological selenium to destroy insect eggs and reduce the reproduction of insect eggs.

Eggplant is one of my favorite vegetables in season, whether it is braised or boiled, or barbecued eggplant, I love to eat, we plant a small amount of eggplant in the countryside is generally not easy to grow insects, no eggplant can be sprayed a little pesticide before the prevention. Eggplant is an important crop in our country. Compared with other vegetables, the cultivation and management process of eggplant is more complicated, and the occurrence of diseases and pests of eggplant is very frequent.

Eggplant cotton blight, eggplant cotton blight mainly occurs in the high temperature and high humidity environment, commonly known as eggplant blight, eggplant blight mainly causes eggplant fruit rot, loss of commercial value, and at the same time to the eggplant seedlings, young branches and leaves and other parts of the harm eggplant wilt disease. Eggplant wilt is also a fungal disease of the subphylum Semi-Homomycetes, which gradually develops from bottom to top, and the leaves turn yellow between the leaf margins and veins, and then develop to the edge of the leaf or the whole leaf wilts and finally falls off.

Prevention and control methods: choose varieties with good disease resistance for planting, disinfect seeds and soil before planting, select sunny and well-drained plots, and spray sterilization with pesticides when the disease occurs.

Common diseases are aphids, spider mite, sclerotinia sclerotinia sclerotinia and cotton blight, cataplexy, when this disease is found, be sure to use carbendazim for spraying, and also pay attention to keeping warm and ventilating at any time, kill the diseased plants, and do not let him infect other plants.

Cataplexy usually occurs in the seedling stage of eggplant, and the disease is characterized by water stains at the base of the seedling near the soil, and later shrinks into a linear shape. To prevent the occurrence of this disease, it is necessary to ventilate the plants, maintain proper light, and avoid overwatering. When the disease is diseased, it can be prevented and treated with 58% remycin 800 to 100 times or Priclix 600 times.

Cataplexy, cotton blight, sclerotinia sclerotiorum, these are all diseases that will occur when planting eggplant, we must carry out weed treatment in the field when planting eggplant, and we must prevent the prevention and control of pests and diseases in advance, so as to reduce the appearance of pests and diseases.

Cataplexy, cotton blight, sclerotinia sclerotinia disease, aphids, red spiders, etc., these are relatively common diseases that need to be controlled when planting.

Generally, in the process of planting eggplant in our rural areas, if the management is not done properly, there will be some physiological diseases, such as low temperature obstacles, deformed fruits, nitrogen overabundance, plant overgrowth and other physiological diseases. Most of the diseases that cause harm on eggplants are parasitic. Such as wilt cataplexy, cotton plague, brown striae verticillium wilt, etc.

At the same time, there are also a variety of physiological diseases, such as stiff seedlings and leaf rolling, burning leaves and yellow leaves, falling flowers and fruits, cracking fruits, sunburn umbilical rot, hollow fruits, poor coloring and other problems.

Brown streaks will be produced on the eggplant fruit, which will have irregular brown sunken lesions, and there will be obvious ring lines after the lesions are enlarged, and many small black spots will be produced on the spots, and some lesions can be as large as half a nightshade, which will eventually cause rotten fruits. The main diseases of eggplant are soil-borne diseases, such as root wilt, verticillium wilt, etc., which are all heavy crop diseases. It is extremely difficult to control, and grafting treatment should be considered if continuous planting is necessary.

If no grafting, the interval should be more than five years.

Soil carriers are the main source of infection of this disease, which is caused by direct invasion from root wounds or young root epidermis, and the disease will be aggravated in low-lying places, heavy soil, too much irrigation, insufficient fertility, early planting, too deep seedlings, and serious root injury. This disease is generally in the early summer rainy or rainy plum rain or autumn rainy, foggy years are more serious, its main damage to fruits, leaves, stems, flowers, will cause a large number of fruit rot.

In the early stage of eggplant cotton blight, the lesions are water-stained and round, rapidly expanding and extending to the whole fruit, the lesions are brown or dark brown, gradually shrinking and softening, when the humidity is high, the disease is full of hairy white hyphae, and finally the diseased fruit rots or becomes a zombie fruit. After transplanting at the seedling stage, the eggplant seedlings were frost damaged. Due to the lack of timely protection, or the protection is not in place, if it is not too serious frost damage, from the leaf point of view, there are no particularly obvious symptoms, but it is easy to cause the phenomenon of stiff seedlings, to avoid the deformity of the fruit, the fruit shape after tomato treatment can be better.

Eggplant diseases mainly include cataplexy, brown streak, wilt, cotton blight, bacterial wilt, verticillium wilt, etc. Cataplexy occurs at the seedling stage, the seedlings are water-stained near the base of the soil surface, and then shrink into a line, the cotyledons are not withered, and the seedlings have fallen on the surface.

Solana cataplexy.

Cataplexy, also known as microfoot plague, is an important disease in the nursery stage caused by fungi. The germs are spread by rainwater, irrigation water, and can also be spread by seed carriers. It is easy to develop the disease under the conditions of soil temperature below 15C, high water content, and insufficient light.

It is also susceptible to low-lying, poorly drained and clayey soils, as well as in areas where unrotted compost is applied. The pathogen invades the plant through the wound, and after the seedlings are unearthed, they begin to appear yellow-brown water-stained lesions at the base of the embryon, and then gradually develop to a week around the young stem, and the diseased tissues decay and dry up or are concave and shrinking, so that the seedlings fall and die.

Aphids mainly eat stems and leaves, and they are not very harmful at first, but there are more aphids that are very harmful to plants. Sclerotinia sclerotinia is one of the common diseases of vegetables. The white cotton-like hyphae will grow with the release time. In severe cases, the stems and leaves will die, and eventually the whole plant will die, affecting the yield.

1. Cataplexy.

Cataplexy occurs mainly at the seedling stage of eggplant. At the onset of the disease, the stalk will change color and die, and gradually begin to shrink. The seedlings will cling to the ground until the whole plant begins to rot and die.

It is necessary to pay attention to the prevention and control methods and choose varieties with strong disease resistance. Seeds and soil should be disinfected before planting. It is also necessary to choose plots with good sunlight and easy drainage to reduce the incidence of disease.

In addition, when a disease is found, it is necessary to spray and treat it in time.

2. Cotton blight.

Cotton blight refers to rotten eggplant and is one of the more common diseases. The incidence of this disease is high, especially during the rainy season. The whole fruit will rot if the disease is severe, severely reducing the overall yield.

In the prevention and control, it is also necessary to select varieties with the ability to resist diseases, and disinfect the seeds and soil. During the growth period, it should be pruned in time to ensure good ventilation and light transmittance, so as to promote its better growth. When the disease occurs, it is also necessary to spray and treat it to avoid aggravation of the disease.

3. Sclerotinia sclerotinia disease.

Sclerotinia sclerotinia is a common disease of vegetables, which can harm not only eggplants but also other vegetables. At the time of the disease, white cotton wool-like hyphae will grow at the base of the stem, and in severe cases, the entire stem and leaf will die. This disease is best mainly in the soil, and the sterilization treatment of the soil is more strict.

It is recommended to spray carbendazim wettable powder. When a diseased plant is found, it should be pulled out and burned in time to avoid infection to other plants.

First of all, some pesticides should be sprayed, and then the right medicine should be prescribed, pay attention to the proportion and dosage of pesticides, keep sufficient light, and do a good job of drainage and ventilation.

Ecological control: After the stubble vegetables are pulled into the seedlings, remove the dead branches and fallen leaves and burn them or bury them deeply to reduce the source of mites. Strengthening fertilizer and water management, with a focus on preventing drought, can reduce mite infestation.

To use pesticides and fertilizers in a timely manner, we must do a good job of loosening the soil, we should prune the branches and leaves regularly, we should also do a good job of watering and fertilizing, and we should choose the right agents according to pests and diseases.

Aphids, cataplexy, blight, brown streaks, cotton blight, these are all very good, and they all need to be controlled.

In the early stage of blight, irregular dark brown lesions appeared at the base of the seedling stem. In the middle stage of the disease, the cortex of seedlings changes color and rots, the stems shrink and become thinner, and the stems and leaves wilt during the day and recover in the morning and evening. After a few days, the whole plant dies and does not lodging. This is the most obvious difference from cataplexy.

Symptoms: eggplant may occur throughout the growth period, will harm the eggplant leaves, the impact on the fruit is not too great, the leaves appear small white spots in the early stage of the disease, with the aggravation of the disease, the spots will continue to expand, and finally in severe cases, the leaves will curl up and become smaller, and become deformed.

<> aphids, very annoying, commonly known as greasy insects, but the eggplant aphids that harm greenhouses and solar greenhouses are mainly cotton aphids. Cotton aphid more than ten generations a year, especially able to reproduce a family, warm climate and dry air is conducive to reproduction, overwintering, reproduction and damage on greenhouse vegetables, eggplant root knot nematode disease is caused by plant parasitic nematode - guava root nematode. Nematodes overwinter in diseased tissues as adults or eggs or as larvae in the soil.

Soils and fertilizers with insects are the main causes of the disease. In the following year, the larvae that overwinter or the larval mites hatched from the overwintering eggs generally prefer a high temperature and arid environment, so the temperature of the greenhouse is first lowered and the air humidity is increased. Prevention is generally used avermectin, pyridoxalin, etc., and insect pests that have appeared can be sprayed with spirodifen, ethoxazole, acetazole and mitenitrile, etc., to strictly eliminate the source of overwintering insects in plant residues and weeds.

In the early stage of insect infestation, 500-2000 times of 25% deltamethrin EC or 1000-2000 times of 20% deltamethrin EC should be used to spray water.

Taking advantage of the phototaxis of insects, pests are trapped through insect traps. When in the seedlings, the height of the hanging should be 10-15 cm higher than the seedlings, and when the height of the plant grows close to the insect trap board, it should be increased by 10-15 cm with the increase in plant height. In just a few minutes, when the insect trap board is combined with tillage or stubble preparation, the insect pupa is drowned by large water irrigation.

When insect pests are found, they should be sprayed immediately with 3000 3500 times of cypermethrin or 2000 times of 40% chrysanthemum emulsifiable concentrate.

Eggplant diseases mainly include: wilt, blight, anthracnose, leaf spot, fruit rot, etc., and insect pests include thrips, bugs, Spodoptera litura, and underground pests. It should be based on agricultural control, supplemented by physical control and chemical control.

Scientific prevention and control. Eggplant should pay attention to mites and red spiders. The main diseases of eggplant are:

blight, blight, anthrax, leaf spot, fruit rot; The main insect pests are: thrips, bugs, Spodoptera litura, and underground pests. Blight, blight, anthrax, thrips, bugs, etc.

Eggplant mainly has early blight, cataplexy, blight, brown streak, cotton blight, aphids and other pests and diseases. A combination of physical prevention and drug prevention and treatment. The main diseases of eggplant are wilt, blight, and anthracnose, which are mainly controlled by biological and use pesticides as little as possible.

The first point is that this green virus will cause the leaves to become all holes, the second point is that the black pest will cause the eggplant to die instantly, the third point is that the disease of rotten seedlings will melt away the whole eggplant, and the fourth point is that if you want to prevent it well, you should cultivate and fertilize it in time

Eggplant is mainly bacterial wilt, sclerotinia sclerotinia and other diseases, and the most common are aphids and red spiders. The main pests and diseases of eggplant are sclerotinia sclerotinia disease, cataplexy, cotton blight, aphids, and red spiders. Common diseases of eggplant planting include cataplexy, cotton blight, sclerotinia sclerotinia and brown streak; Common insect pests include aphids, red spiders, etc.

Eggplant mainly has thrips, planthoppers, diamondback moths and other pests and diseases. Eggplant diseases and insect pests mainly include Verticillium wilt, cotton blight, red spiders, aphids, etc.

The common diseases of nightshade crops at the seedling stage include cataplexy, anthrax, leaf spot and other diseases. In the middle and late stages of its growth, it is more harmful to have bacterial wilt, verticillium wilt, wilt and other diseases. These diseases, except for anthrax and leaf spots, are all soil-borne diseases.

If the soil has not been disinfected before transplanting. The above diseases are more likely to occur.

It is recommended to alternately use 500 times of 70% metylthiophanate-a-methyl or 77% copper hydroxide wettable powder, or 800 times of downy mildew aqueous agent to spray stems, leaves and root irrigation, and use about liters of diluted solution for each root irrigation, once every 7-10 days, and about 2-3 times in a row to prevent cataplexy disease. After slowing the seedlings and in the middle of growth, irrigate the roots with 1000 times of 50% chlorobromoisocyanuric acid soluble powder, or 4000 times of 72% agricultural streptomycin sulfate soluble powder, or 300 times of 50% copper succinate wettable powder, and the plant irrigation dilution solution is about liters, and the medicine is filled once every 7 days, and the medicine is used 2-3 times in a row to prevent diseases such as wilt and blight.

In the meantime, use 25 grams of prochloraz EC 1000 times, or 10% difenoconazole water dispersant 1000 times, spray stems and leaves once every about 7 days, and spray 2-3 times continuously to prevent anthrax and leaf spot.
