During the rainy season, the eggplant grown in the greenhouse has insect infestation, what should I

<> eggplant is vulnerable to pests and diseases if it is not properly maintained during the growth period. Common insect pests include eggplant lice, aphids, etc., which can endanger the young leaves of eggplant and affect the growth of fruits. During the maintenance period, if the eggplant is infested by insects, it is necessary to prune the insect leaves, and then spray it with chemicals such as worm forest, phosphine or dimethoate oxide to remove insects.

If it is a relatively large insect, we can manually remove the insects on the eggplant leaves, and if there are eggs, you can wipe them off with a soft and moist paper towel, so that you can eliminate the insects, note that this method is only suitable for the situation that the eggplant is not serious.

If you want to avoid insects on the leaves of eggplant, then when planting eggplant, it is best to use some insecticidal and sterilizing agents to disinfect the soil, and then plant eggplant, so as to prevent eggplant from the inside of the insect infestation.

Irrigating the roots with the medicine of Fusarium wilt is effective in the early stage. Aphid mites on eggplants can be controlled by pymetrozine. Gram mites and Nisolan are both agents with better acaricidal effects.

Eggplant has mites and works well with gram mites. Eggplant mite diseases can be selected: Gram mite, mite net, Nisolan and other drugs for spray control.

After spraying, it is necessary to maintain the eggplant reasonably, fertilize and water it appropriately. After the eggplant recovers in the later stage, it can be given sufficient fertilizer, water and light, which is conducive to the growth of the eggplant. In the later stage of maintenance, you can regularly spray carbendazim or chlorothalonil and other fungicides on eggplant, which can effectively induce pests and diseases.

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!

To sum up, there are many pests and diseases of eggplant, I will briefly introduce a few here, and they are also the most common pests and diseases, do a good job of prevention and first-class methods, and improve the yield of eggplant!

According to the diseases and pests of eggplant, choose the right insecticide, pay attention to the planting density in the planting process, be sure to do a good job of loosening soil drainage, be sure to do a good job of ventilation, to ensure soil fertilizer, to fertilize in time, and to do a good job of prevention.

After this situation occurs, we must do a good job of ventilation, we should open doors and windows for ventilation, we must choose the right insecticide according to the pests that appear, we must do a good job in soil drainage, we should also loosen the soil in time, and we should water and fertilize in time to ensure soil fertility.

Be sure to spray pesticides in time, pay attention to ventilation, find the root cause of the problem, and strengthen nutrition, eat some organic fertilizer appropriately.

Prolonged rain will reduce the permeability of the soil, will affect the respiration of the roots of the plant, if the soil is waterlogged, the plant is easily waterlogged, the plant is waterlogged lightly leads to root rot, heavy leads to plant death, easy to lead to fruit rot. In the early stage of eggplant cotton blight, the surface of eggplant fruit will show water-soaked round lesions, and with the development of the disease, the lesions will gradually expand and become brown. Eggplant is caused when the humidity in the field is too high due to continuous rain or frequent rain.

<> strengthen management and choose fertile soil with high terrain and good drainage to cultivate eggplant. Ridge planting, when the rainy season comes, clean the ditch, drain the water in time after the rain, and lightly water the well water to prevent the harm of hot rain. Apply plantar fertilizer, top dressing in time, increase phosphorus and potassium fertilizer, and avoid partial application of nitrogen fertilizer.

The symptoms of eggplant brown streak disease are as follows: brown round depression spots, many small black spots on them, arranged in a ring pattern, the lesions continue to expand, up to the whole fruit, and the diseased fruit falls to soft rot in the later stage, or stays on the branches, showing dry rot and disappearing stiff fruits. Fungicide prophylaxis is sprayed every 7 10 days, and the commonly used ones are iprodione, ethylene sclerotinitum, and Dysenlian.

At the same time, according to the growth of the plant, foliar fertilizer can be sprayed to enhance plant resistance, improve low temperature tolerance, and improve fruit quality. When administering drugs to prevent disease, it should be notedNightshade blight:In the event of cotton blight, the leaves of eggplant plants will produce lesions and white mold.

In particular, the fruit was the most damaged, with water-stained round spots and slight depressions, and the flesh of the eggplant was black-brown and white.

Find a way to reduce humidity. Most diseases are prone to occur in the case of high humidity, in the rainy season we need to dig drainage ditches in advance, to ensure that there is no water accumulation in the field, if the soil is too wet we can sprinkle grass ash on the soil. The ash of plants and trees can not absorb the excess, and it is mostly rotten, and there is a foul smell, but the fruit does not grow hair, and the fruit is muddy, and the fruit will fall from the eggplant in serious cases, commonly known as "falling eggs".

This is the bacterial soft rot of eggplant, which is the most commonly known disease on eggplant.

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.

Verticillium wilt is a vascular disease in which we cut the rhizome and find that the internal vascular bundles are brown or black. The main symptoms are: at the beginning of the disease, the lower leaves of the plant are atrophied and the leaves are rolled up; After a period of time, the leaves turn yellow, which can be used to prevent small pests such as ants, crickets, grasshoppers, and leads.

This method is also the most used method by farmers in Ah Xiang's hometown, and it is also very effective. Tip: Don't sprinkle lime everywhere, and when planting eggplant, don't go near lime, because lime is alkaline and can cause damage to eggplant.

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 cotton blight is the eggplant disease in the early stage of susceptible plants, leaves and side branches wither for a long time at noon, the wilted parts or leaves gradually expand and increase, and gradually spread to the whole plant, resulting in the whole plant wilting, When the stem is high humid, there is vascular browning and white mildew before graying.

Xinke plant protection rotten roots and dead seedlings 120 can be used for spraying or irrigation, which can play a role in sterilization of soil and crops. In the planting process, attention should be paid to reasonable control of water and fertilizer, intensive cultivation to ensure the permeability and activity of the soil, and provide a high-quality soil environment for crops. Before the leaves have fallen, they have fallen to the surface.

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.

Due to the failure of fertilizer**, it is necessary to spray foliar fertilizer** in the evening to grow. The insect insect eggplant lice damages the leaves, makes the eggplant sick, and even makes the eggplant harvest. Root maggots harm eggplant fruits, so that the quality of eggplant Shifan declines, and is not favored by consumers.

In the morning and evening, spray the ground of the field with inulinolin medicine. Its plots are cultivated in sandy loam soil with flat terrain, fertile soil, slightly acidic to slightly alkaline, moisture retention and good drainage. It is required to turn over in autumn and harrow in autumn, apply foot fertilizer on the basis of fine land preparation, apply high quality per mu, and 23 cubic meters of agricultural fertilizer to improve crop disease resistance.

When choosing eggplant, Nasun must choose some healthy ones, and then spray the land with Dongbi chain pesticides when planting eggplants, and then spray pesticides after good planting, and spray pesticides on time according to the growth cycle of eggplants.

In early spring, the first thing to pay attention to is the temperature control and timely watering, and the appropriate application of organic forest fertilizer. It is also necessary to spray pesticides that can prevent some pests and diseases, and remove the eggplants that have been affected to prevent the infection of other eggplants.

First of all, it is necessary to ventilate in time, and then use some chemical ingredients to remove insects, do not let the room temperature be too humid, and make the temperature a little higher.

Pesticides must be sprayed in a timely manner, and ventilation management must be strengthened to remove stagnant water in a timely manner.

Eggplant diseases are usually caused by fungal infection, and carbendazim can be sprayed several times in advance to prevent and control.

The specific diseases of eggplant growth links include cotton blight, brown streak, bacterial wilt, aphids, red spiders, etc., which should be moderately sprayed with purposeful drugs (such as 0 5 Bordeaux liquid, 65 zeb wettable powder 500 times, 75 chlorothalonil wettable powder 600 800 times liquid) according to plant protection requirements to carry out prevention, and add 800 times of new high-lipid film liquid spraying at the same time, which can improve the control effect.

The pruning technology when planting eggplant is how to select the time period, and many eggplant growers should also understand that the pruning of eggplant must watch its development and time to achieve selection.

At this time, the eggplant is mainly manifested as some branches of the branch, and there are signs of withering, and some of them even gradually terminate the fruit, generally to this period of time in the process of the most important pruning, in the normal season most of the eggplant can be pruned around the end of July, if it is out of season, you can judge the actual time according to their growth status.

The pruning technique when planting eggplant is how to carry out accurate search for the pruning part, generally in the case of pruning, the second pruning part is the non-type eggplant cherry is often diversified, some are pruned at that time to prune some withered branches, and some in the process will be immediately detected from some development, according to the species of eggplant planted to achieve the method of selection and pruning if the growth rate of the plant is faster.

And if the yield is high, it is generally mainly to prune the withered branches, and that can ensure the high yield of eggplant, if it is dominated by greenhouse farming, you can try to gradually prune from his neat 10 to 15 cm or so.

How to carry out pruning of planting eggplant, after the end of pruning in the past, it is for the solution after pruning, after the pruning, a series of solutions should be carried out for the wound of the pruning part, and scissors must be used to carry out pruning, such as the fruit is broken, it will cause secondary damage to the branches of the eggplant.

First of all, some pesticides should be sprayed, and at the same time, we should also prescribe the right medicine, choose some herbicides and insecticides with better effects, and then we should also pay attention to the temperature control, the temperature should be set at about 13 to 25, and then we should also do the work of dismantling the ruler and answering the drainage and ventilation.

It is necessary to water and cover in time, and it is necessary to ensure the fertility of the soil, and it is necessary to pay attention to the spacing of planting and the density of planting.

To prevent damage in advance, spray some pesticides in advance, and do a good job of management measures to pay attention to the situation of germs.

First of all, let's talk about low temperature barrier, this physiological disease in the growth process of eggplant, if you encounter a slight low temperature, there will be a decrease in chlorophyll, yellow spots near the petioles, the growth of diseased plants is slow, the plant stops growing, and most of the diseases that cause harm to eggplants at lower temperatures above freezing point are parasitic. Such as wilt cataplexy, cotton plague, brown striae verticillium wilt, etc. At the same time, there are also various physiological diseases.

Such as stiff seedlings and leaf rolling, burning leaves and yellow leaves, falling flowers and falling fruits, cracking fruits, sunburn umbilical rot, hollow fruits, poor coloring and other problems.

It is an important fungal disease of eggplant that occurs all year round, causing fruit rot after the onset of the disease. Brown streaks will be produced on the eggplant fruit, irregular brown sunken lesions, the lesions will have obvious ring streaks after enlargement, many small black spots will be produced on the spots, and there will be gray-brown mildew at the calyx of the young fruit stage, and then the rot will become larger and larger until it falls off. Cotton blight is water-stained mildew.

There is no difficulty in dealing with the symptoms**. The insect infestation is dominated by red and white spiders (mites). Powdery mildew in the later stages should also be a concern.

Pharmaceutical defense: the prevention and control should be early, focusing on the protection of the eggplant at the lower part of the plant, and the pesticides that can be selected are chlorothalonil, mancozeb, ethylphosphine aluminum, manganese-zinc fine methyl frost, downy mildew, manganese-zinc frost, etc. : At the beginning of eggplant cotton blight, the lesions are water-stained and round, and rapidly expand to the whole fruit.

The lesions are brown or dark brown, gradually shrinking and softening, and when the humidity is high, the diseased fruit is covered with hairy white hyphae, and finally the diseased fruit rots or becomes a stiff fruit.

The main reasons for the occurrence of Gemini eggplant are that eggplant encounters low temperatures below 5 degrees Celsius during the flower bud differentiation stage, and excessive use of fertilizer and overwatering leads to excessive nutrients. There are also vegetable farmers who use growth regulators in excessive concentrations, and they are also prone to Gemini eggplant. 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 relatively easy to cause the phenomenon of stiff seedlings.
