What should I do if there are always worms on the eggplant? Is there any way to prevent it?

It can be sprayed with a pyrethroid insecticide and can be consumed a week after spraying.

There are many insects on the leaves of eggplants, and the leaves need to be cut off and burned in a concentrated manner, and the eggs do not multiply in large quantities. After pruning, the eggplant can be sprayed with chemicals such as worm forest, phosphine or dimethoate. If there are fewer insects, you can spray vinegar solution, alcohol solution and pepper water, spray regularly, do not stop using it halfway, and can get rid of the insects.

During the growth period, if the eggplant is not properly maintained, it is easy to be attacked by diseases and insects. 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.

During the curing period, it is necessary to strengthen the curing, and if it is in the initial stage, you can make your own sterilization solution to remove insects. In the early stage, there are fewer insects on the eggplant, and most of them are larvae, so you can spray them with vinegar solution, alcohol solution and pepper water, etc. After spraying the eggplant 1 time between 3 and 5 days, spraying 2 or 3 times in a row, it can get rid of pests.

In the later stage, there are many insects on the eggplant, and the leaves need to be burned intensively after pruning to cut off the source of infection. When spraying chemical agents on eggplant, it is generally sprayed once in about 7 10 days, and the agent should not be stopped halfway, otherwise it will affect the efficacy. During spraying, a variety of agents can be used alternately, and after spraying 3 or 4 times in a row, it can be used to remove insects.

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.

Hello, glad you file a difficult question.

For the insect pests you mentioned, you can consider using phosphine EC, kung fu EC, killing EC, Mengweiling, avermectin, imidacloprid, Emilor and other agents to be diluted in rotation and sprayed. Choosing the right insecticide for different pests can quickly remove pests and diseases from eggplants.

And, it needs to be pruned and burned in time.

If you don't expect the eggplant leaves to be damaged by insects, it is best to use a clean, clean and sharp pruning knife in time, and Xingchun Nian will cut them all together with the petioles, and collect them and burn them intensively. Treating the leaves in this way cuts off the source of transmission of the pest.

The ** of each eggplant disease is different, so it must be solved on a case-by-case basis. If you use it blindly, it can be counterproductive. The worst outcome is that the eggplant dies.

When using chemical pesticides for prevention and control, farmers should pay attention to two aspects. One aspect is the prevention of drugs, and the other is the prevention and treatment of drugs. Prophylaxis is mainly used in the early growth of eggplants.

Pesticide control is mainly in the late growth stage of eggplant. If eggplant needs to be controlled multiple times, it is necessary to pay attention to the rotation of different agents. Because if one agent is used all the time, it may make the eggplant resistant.

In order to be effective against eggplant disease, it is necessary to understand the common diseases of eggplant. In the production of eggplant, there are five common diseases of eggplant: brown streak, Verticillium wilt, cotton blight, gray mold and bacterial wilt. Many people may not know about these diseases.

But the people who grow eggplants must have seen it. Some of these conditions are detected at an early stage or at a later stage. Therefore, when eggplant is growing, production personnel must always pay attention to the growth dynamics of eggplant.

This is conducive to the timely prevention and control of eggplant diseases and pests. <>

In addition to knowing the common pests and diseases of eggplant, it is also important to know how to**. Although all are controlled by chemicals, the methods used for each common pest and disease are different. For these pests and diseases, the general chemical control idea is to start from the seedling stage for preventive medicine, once found eggplant has related diseases, must be used as soon as possible to prevent and control.

In the process of implementation, the commonly used methods are seed disinfection, seedling soil disinfection and pesticide root irrigation. <>

Every vegetable is ripened through arduous growth. In the process of growing, these vegetables are affected not only by the environment, but also by bugs. When the growth temperature of eggplant changes too quickly, eggplant is prone to disease.

Eggplants are also susceptible to disease when the soil of the eggplant changes. For the cultivation of eggplant, the production staff is very hard.

1.Fusarium wilt disease disease generally from the bottom to the whole plant disease, at the beginning of the disease, the leaf edge and leaf veins turn yellow, the whole leaf turns yellow in the later stage, the diseased leaves are generally wilted, until the withering falls, when it is serious, the leaves of the whole plant will fall off only the stem. Prevention and control methods:

In the early stage of plant disease, carbendazim or thiophanate-methyl suspension can be sprayed for control.

2.Cotton blight This fungal disease caused by the fungus Phytophthora nightshade. In low-lying areas, where nitrogen fertilizer is applied and over-dense planting, the spread of the disease will be exacerbated.

Prevention and control methods: To prevent and control cotton blight, it is necessary to spray 68% enoylmorpholine and 58% methalene at the peak fruit stage. Mengzinc is sprayed once a week, a total of 2-3 times.

3.Verticillium wilt Verticillium wilt generally occurs after fruit set, with symptoms appearing in the lower middle of the plant, wilting on sunny days in the early stages of the disease, recovering sooner or later, and not recovering after severe illness. The branches and leaves turn yellow, and the vascular bundles turn black-brown.

Prevention and control methods: In the early stage of the disease, you can choose to irrigate the roots with 50% carbendazim 500 times, once every 10 days, 2-3 times in a row.

From the seedling to the fruit stage, there are many diseases and insect pests that often occur in eggplant, including blight, cataplexy, virus disease, tomato wilt, late blight, early blight, gray mold, leaf mold, and umbilical rot; eggplant brown streak, cotton blight, root rot, verticillium wilt; Pepper blight, anthracnose, scab, sun burn, cotton bollworm, tobacco worm, aphid, whitefly, etc.

First of all, when planting eggplant, it is necessary to select disease-resistant varieties, and implement ploughing, crop rotation, stubble, and strengthen the work of cultivating and weeding, so as to reduce the source of infection, find latent pathogenic bacteria and hidden insect pests, and do a good job of shading treatment, improve plant stress resistance, and reduce the occurrence of viral diseases.

Secondly, the seeds of eggplant are directly related to the yield in the later stage, generally speaking, 10% trisodium phosphate should be used to soak the seeds, and seed dressing agents can also be used to dress the seeds to ensure the resistance of eggplant seeds, so as to reduce the probability of pests and diseases in the planting process.

Spray pesticides on time, pay attention to watering and fertilization, pay attention to the selection of varieties, and clean up weeds, so as to effectively prevent diseases.

For the prevention and control of eggplant diseases and pests, prevention and control measures should be taken in advance to avoid pests and diseases affecting the cultivation efficiency of eggplant. It is necessary to accurately grasp the key points of eggplant cultivation technology, reasonably arrange planting activities, summarize the types and occurrence rules of common pests and diseases in the area, and carry out targeted prevention and control.

1.Prevention and treatment of Verticillium wilt.

Verticillium wilt usually invades the vascular tissues of eggplants during fruit set. After infection, the leaves turn yellow, gradually wither at noon, and slowly recover at night. If not, it can lead to a large number of leaves falling off or even the complete death of the plant.

When the stems of the dead plant are removed, the vascular tissue is brown. Bacteria can survive in the soil for many years. Climate and management are the main causes of this disease.

Low temperature and high humidity can aggravate the condition. Rotation or unscientific fertilization of nightshade vegetables will increase the occurrence of Verticillium wilt. To prevent Verticillium wilt, seeds can be soaked in carbendazim wettable powder for about 2 hours.

The rotation of eggplant and fruits and vegetables should be maintained for more than 2 years. Cultivate strong seedlings and enhance the disease resistance of seedlings. Soak the roots in zinc toluene wettable powder for about an hour.

2.Brown lesion control.

When the eggplant turns brown, it forms dark brown spots. After invading the leaf stem, the center of the spot gradually changes from dark brown to grayish-white with small swirling black spots. Infected seedlings will form lesions at the base of the stem, resulting in an increase in the seedling quenching rate.

Brown streaks are found in the seed epidermis, diseased bodies, and soil, and are spread in a variety of ways. A job rotation system should be reasonably established to improve the level of on-site management. Sterilize the seeds inside the seedlings and soak them in warm water and medicine.

Or use carbendazim wettable powder and filler for seed dressing. After transplantation, lime powder and plant ash are used to reduce stem morbidity.

Pest control requires the flexible use of biological, physical and other prevention and control technologies to improve the prevention and control effect. In order to effectively control whitefly, yellow plate can be used to kill whitefly. Generally, 35 pieces can be set per mu.

The natural enemies of whiteflies, such as aphids and sandflies, can also be introduced for control. For more severe cases, imidacloprid emulsion should be used. To control aphids, you can reasonably set up insect nets, or hang yellow boards between the eggplant rows.

The difference between the height of the yellow plate and the plant is about that.

Common diseases of eggplant include cataplexy, brown streak, blight, etc., and common pests mainly include aphids and eggplant, which need to be prevented in advance and prescribed the right medicine.

It should be noted that in the process of eggplant growth, it is necessary to spray pesticides twice, and it is also necessary to pay attention to watering and fertilizing during the growth process, which are very important, and must pay attention to a control of time.

First, we should take scientific and effective measures to accurately grasp the relevant technical points. Second, we should adopt targeted technologies to solve various problems. Third, we need to control the amount of fertilizer and watering, and we can use more biological or physical prevention and control technologies.

Fourth, we must clean up the surrounding weeds and pests and diseases, and we can properly spray some beneficial medicines.

Selection of varieties, time of seedling rearing, etc. Selection of varieties, choosing early-maturing and cold-tolerant varieties will reduce the occurrence of pests and diseases; The seedling raising time is generally sown in late December and planted in March of the following year, and the pests and diseases will be relatively reduced.

Before planting eggplant, the soil needs to be thoroughly ploughed, weeds and plant residues in the field should be removed, and they should be harmlessly treated to reduce the probability of aphids. Use the natural enemies of aphids to control their organisms, such as ladybugs, spiders and other animals that can eat aphids can be placed in the field; After the eggplant is harvested, the plants need to be cleaned and the soil disinfected.

<> eggplant seedlings have insects, it is necessary to distinguish which pest it is, and then use the corresponding insecticide to spray the eggplant seedlings, so that the pests can be removed.

1. Spraying**.

If the eggplant seedlings have insects, it is necessary to spray the eggplant seedlings with insecticides, first distinguish which pest it is, and then use the corresponding drugs to spray the eggplant seedlings, so as to completely kill the pests, otherwise the insect infestation is serious, and the eggplant seedlings will have poor growth and wilting.

2. Suitable light temperature.

When breeding eggplant seedlings, it is necessary to let them have sufficient light exposure, so as to facilitate its leakage photosynthesis, so that eggplant seedlings can grow vigorously, the temperature is about 25 is the best, if the temperature is too high, it is necessary to take ventilation measures for eggplant seedlings in time, so as not to be in a stuffy environment.

3. Reasonable watering.

The growth of eggplant seedlings needs sufficient water, but if there is water in the soil, it will appear to be rooted, so in dry weather, it is necessary to water eggplant seedlings more to keep the soil slightly moist is the best, but in rainy weather, it is necessary to drain eggplant seedlings in time.

4. Apply thin fertilizer frequently.

Eggplant seedlings during the growth period, but also need to return to the empty mu to apply thin fertilizer frequently, generally planting, need to apply basal fertilizer in the soil first, in order to improve the fertility of the soil, after planting, to apply a seedling fertilizer in time, so that the ruler can promote the vigorous growth of eggplant seedlings, pay attention to not apply fertilizer or thick fertilizer to it.

Eggplant belongs to a kind of vegetable with large market demand and good planting prospects, especially the eggplant listed in early spring** is expensive, eggplant is nutritious, there are many ways to eat, frying, stir-frying, cooking, frying, stewing, etc., which are very popular with people. Eggplant is highly resistant to disease, has a long harvest time and high yield in one planting, from spring planting until frost falls. Eggplant can grow for a long time, subject to many external disturbances, many of which have diseases, eggplant common pests and diseases generally include eggplant cotton blight, eggplant gray disease, eggplant verticillium wilt, eggplant brown streak, red spider, 28-star ladybug, etc.

What do we need to pay attention to in terms of prevention and control?

1. Eggplant cotton blight, eggplant cotton blight mainly occurs in the environment of high temperature and humidity, commonly known as eggplant blight, eggplant blight will mainly cause eggplant fruit to rot, lose commodity value, and at the same time cause harm to eggplant seedlings, young branches and leaves, etc., eggplant cotton blight is one of the eggplant diseases, the harm is relatively serious, and the occurrence of eggplant blight is heavier, which will cause the economic benefits of eggplant to shrink significantly. Eggplant in the seedling stage of low temperature, high humidity, prone to blight, eggplant seedlings and cataplexy disease, fall to the ground, in the roots of eggplant seedlings have a white flocculent layer, eggplant leaves appear disease, first from the tip of the leaf to infect the disease, the lesion part seems to have been soaked in water, the edge is irregular, and then die, when the humidity is high, there is a white fungus. Most of the fruits are diseased from the ground nearby, and there are near-round lesions on the surface of the eggplant fruit, with water stains and rot.

Eggplant cotton blight is easy to occur, too much nitrogen fertilizer is used, eggplant plants grow too vigorously, not strong, the field is shady, easy to accumulate water after rain, and the plots that have been planted after successive years are the most prone to disease.

2. Eggplant dry rot, eggplant dry rot is also called eggplant brown streak. It can be harmful to all parts of the eggplant plant. Eggplant ash disease is also important.

3. The choice of planting place, in the process of planting eggplant, it is better to choose loam soil that is slightly higher in terrain, not waterlogged after heavy rain, half silt and half sand, and the planted eggplant can not be too dense, which affects the ventilation and light transmission ability of eggplant, and the eggplant is tall, and generally not more than 2,000 plants per mu of land are planted as well, so as to prevent a variety of diseases of eggplant.

4, the choice of disease-resistant varieties, eggplant varieties are different, disease resistance is also different, according to the usual planting experience, the greenhouse cultivation and planting of round eggplant is better, the round eggplant has good low temperature resistance, and the disease resistance is relatively strong. If the incidence of cotton blight is more severe, it is more important to choose round eggplant for planting. Generally, white-skinned eggplant, green-skinned eggplant, long eggplant, etc., have better resistance to dry rot, and it is worth choosing to plant.

5. Pesticide prevention and control, eggplant diseases, mainly to prevent, sprayed fungicides, generally should have high efficiency and low toxicity, with the dual role of protection and ** as well, for example, ethylphospho aluminum manganese zinc, mancozeb, chlorothalonil wettable powder, manganese zinc, manganese zinc, amicida, iprodione, take the enemy and so on. Spider mites can be sprayed with 2000 times liquid avida digen. The 28-star ladybug is a pest, and it can be controlled by spraying 1000 times of high-efficiency permethrin.
