What are the control measures for pests and diseases during eggplant planting?

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.

Choose disease-resistant varieties, eggplant varieties are different, disease resistance is also different, according to the usual planting experience, winter greenhouse cultivation planting round eggplant is better, round eggplant low temperature tolerance is good, disease resistance is also relatively strong. If there is a more serious cotton wilt, the round eggplant should be planted. Generally, white-skinned eggplant, green-skinned eggplant, long eggplant, etc., have good resistance to dry rot and are worth planting.

Pesticide prevention and control, eggplant diseases, should be based on prevention, spraying fungicides, generally should have high efficiency, low toxicity, protection and good dual effects.

After planting eggplants, you can spray some pesticides, you should water frequently, increase the time of sunlight, and remove the leaves with insects so that you can control pests and diseases.

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

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.

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.

1.Eggplant cotton blight is seriously damaged in rainy years. Hazard characteristics:

It is mainly harmful to fruits, but also to harmful leaves, stems, and flowers. The leaf damage produces irregular round water-soaked brown lesions, with obvious wheel lines, and white mold grows on the lesions when wet. At the beginning of the fruit, there are water-soaked round lesions, slightly concave, black-brown, and then gradually expanding, causing damage to the whole fruit.

When wet, white cotton wool grows on the lesion, and the flesh is brownish-black, rotten, easy to fall off or shriveled and shrink into a stiff fruit. The stem is water-soaked and shrinking, and the upper part is wilted and easy to break. Prevention and control methods:

1) Seed treatment with nail cream. Manganese-zinc soaking is followed by germination sowing. (2) Choice of pharmacy:

Mancozeb, enoylmorpholine + chlorothalonil, pyraclostrobin, azolestrobin + chlorothalonil, etc. 2.Eggplant early blight can be diseased at the seedling stage and the adult plant stage

It mainly damages leaves and fruits. Leaf disease: nearly round or irregularly shaped lesions are produced in the early stage, the edges are brown, the middle part is gray and white, and there are concentric wheel patterns.

When the humidity is high, the diseased long is fine gray-black mold, the middle part of the lesion is brittle and cracked in the later stage, and the diseased leaves fall off early in severe cases.

1. Cataplexy.

This disease usually occurs in the seedling stage of eggplant, which is manifested by the fact that the seedlings are water-stained near the base of the soil, and then they will shrink into threads, and the leaves have fallen to the surface before the seedlings have fallen. To prevent this disease, we need to ventilate the plants, keep them in moderate light, and avoid overwatering. It can also be treated with 58% remycin 800 to 100 times or Pricr 600 times.

2. Brown striae.

This disease is also a common occurrence of eggplant, which is manifested by the change of water-stained spots on the leaves to brown wheel stripes with grayish-white and small black spots on the edges. The fruit also develops lesions and slowly develops into a sauce color. In this case, we try to choose varieties with good resistance, do a good job of ventilation, and we also need to reduce the moisture of the soil appropriately.

It can be controlled with 1500 times of promethine solution or 50% 600 times of bacterial dorin.

3. Cotton blight.

This lesion now appears as a number of water-stained round spots on the fruit, which then turn brown and sunken, with the occasional dense white mold, which eventually causes the fruit to rot or even fall off. For this reason, we need to make diligent repairs during the time period when they are growing to ensure the flow of light and air. It can also be sprayed with special drugs**, which will have a good effect.

4. Aphids. The main insect pests are aphids, which can be sprayed directly with special agents**. And there are mites, they are also more harmful, if the flowers that occur can be controlled with 1500 times the liquid of the mite.

Extended information: 1. Eggplant growing conditions.

1. Temperature: eggplant is thermophilic and heat-resistant, and its most suitable growth temperature is 20 30, and its fertilization and fruit development are stunted when it is lower than 20; When it is lower than 15 17, the growth and development are stunted, and the flower loss is serious. When it is less than 13, the growth basically stops. 0 1 when frost damage occurs; Fertility disorder occurs above 35.

2. Light: Eggplant has high requirements for light time intensity. Under the conditions of long sunshine and high intensity, eggplant has vigorous growth, flower buds, high fruit yield and good coloring.

3. Moisture: eggplant likes water and is afraid of waterlogging, because of its lush branches and leaves, large transpiration, and large water demand, the soil field water holding capacity is 80% during the growth period, and the relative humidity of the air is 70% 80%. If the humidity is too high, the disease is serious, especially the soil is waterlogged, which is easy to cause the root to die.

Eggplant has a well-developed root system, which is more resistant to drought, especially before fruit setting, and properly controlling water before fruit setting, and multiple tillage can promote root development, prevent seedlings from growing, and be conducive to flower bud differentiation and fruit set.

4. Soil: It is suitable for cultivation in soil rich in organic matter and strong water and fertilizer retention. Eggplant has a higher requirement for nitrogen fertilizer, and the flower bud differentiation is delayed when nitrogen is deficient, and the number of flowers is significantly reduced, especially in the peak flowering period, if the nitrogen is insufficient, the short column flowers become more and the plant development is not good.

Under the condition of low nitrogen fertilizer level, the effect of phosphate fertilizer was not significant, and the potassium uptake increased sharply in the later stage.

Eggplant is a vegetable that everyone often eats in daily life, but in the process of eggplant planting, there are often some pests and diseases that affect the growth of eggplant. So, how do you prevent these pests and diseases? Today, Brother Zheng is here to answer for you!

Verticillium wilt is a hypothermia disease. The pathogen infiltrates mainly from the root wound. If a long time has passed since planting, then the disease will be very early and severe.

Method: In order to improve the resistance of the seeds, the seeds must be sterilized. The seeds are mixed with more than 50% wet powder or 50% Fumei moisturizing powder, and then more than 50% wet powder is sprayed into the seedling stage for soil disinfection.

From germination to colonization, the root canal can be used evenly with more than 300-30% wet fungal liquid powder or more than 500-50% wet powder, which gives a good effect in the struggle.

Brown spot disease occurs throughout the growth process and can cause withering and temporary wilting of seedlings. In summer, it is very hot and rainy, and a series of phenomena are relatively heavy. Prevention and control methods:

The seeds are sterilized, 75% of the bacteria are washed with dry powder, soaked for 800 times for 2 hours, repeatedly rinsed with water for extraction, germination, drying or drying spare parts. Seed disinfection, home nutrition* or seedbed can be dewatered by mixing powders, injections or root grouting, depending on pre- and post-sowing treatments. Diseased leaves and fruits should be removed as soon as possible.

The control group used 600 times isoureas in a 50-fold or 2000-fold pyrimidine suspension for the moisturizing powder.

Fusarium wilt mainly affects eggplant fruits, leaves and shoots. Eggplant buds can suddenly wilt when injured. Under the conditions of high temperature and high humidity, treatment, weak growth, local application of nitrogen fertilizer and field management aggravated the disease.

Prevention method: 40% triethyl aluminum phosphate wet powder 200 times or 65% zinc wet powder 500 times. In the rainy season, fruits, etc.

After illness, spray 64% liquid, 500 times manganese-zinc moisturizing powder, 58% methyl zinc, and 500 times manganese-zinc moisturizing powder. A seven-day interval can produce great results.

This is how common pests and diseases are treated in eggplant cultivation, thank you!

To spray pesticides in a timely manner, we must prescribe the right medicine, remove insect pests regularly, and then we should also keep sufficient light, keep the temperature appropriate, do a good job of drainage and ventilation, pay attention to the spacing and density of planting, and do a good job in field management and water bill management.

Of course, it is known that spraying pesticides and paying attention to the surrounding situation can be solved by physical control methods and selecting the right varieties for planting.

When planting, we must choose the soil is relatively fertile and broad, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time. I think that if we can do these things well, we will be able to prevent pests and diseases.
