What pests can be found in pepper farming? How can it be prevented?

As one of the essential vegetables on the table, chili peppers are in high demand every year. Therefore, peppers are planted in many areas, although peppers have a strong ability to adapt to the environment, but they will also encounter some pests and diseases in the process of planting, including pepper scabs, virus diseases and blight diseases. Each pest has its own unique control methods, which should be carried out differently for different situations, and the most important of them is to make a variety of medicines.

The most common and common disease of chili peppers throughout the growth period is scab disease. At the time of onset, the leaves of the pepper will appear green patches, and if not controlled, the area will gradually expand and turn brown. The control method is to rotate with non-Solanaceae vegetables when planting, and turn the soil deep to eliminate latent germs, and you can also use drugs to spray to kill germs.

Pepper charcoal maggot disease usually has water-stained lesions in the early stage, and in severe cases, black spots will appear, and when dry, it is especially easy to crack peppers. The control method is usually to select varieties with high disease resistance, and soaking the seeds in warm water before planting can effectively avoid pepper charcoal maggot disease to a certain extent. <>

There is also a very strange disease of chili pepper is chili cataplexy, when the chili pepper is sick, there will be lesions on the neck, and then it will turn yellow and dented, at this time, if you touch the leaves of the chili pepper with your hand, it will fall off on the ground. The prevention and control method is to choose a well-ventilated place for planting when planting, and must be pulled out in time for those who have become ill, and sprayed with drugs for prevention and control. In addition, peppers also have pepper bacterial leaf spot, which mainly damages the leaves of peppers.

When planting peppers, a high ridge planting method should be adopted to drain the stagnant water in time after rain, so that it can be effectively controlled. <>

Peppers, which are loved by many people, have so many pests and diseases in the process of planting. Therefore, in the process of planting, we must do a good job of protection in advance, and we must do a good job of cleaning up in time after the onset of the disease, so as to ensure the yield and quality of peppers.

Aphids will appear, and this pest will affect the yield of peppers very much, causing root rot in peppers, whiteflies, tea yellow mites, and tobacco worms, all of which can be seen when growing peppers. You can use pesticides to control it, or it can be controlled through proper management, pay attention to the requirements of control, and understand the planting skills when planting peppers.

Bladder wilt, pepper blight, powdery mildew, insect infestation, tobacco insects, these are the main insect problems. Usually, when planting, you must sprinkle some insect repellent and insecticides, and you should also pay attention to the disease prevention and control of peppers.

Aphids, cotton bollworms, taboos, cotton bollworms, tea yellow mites, Spodoptera litura,whitefly; Spraying pesticides, cleaning up bad leaves, spraying sprays, spraying chemicals, spraying insect repellents.

Spodoptera exigua, Spodoptera litura, fruit flies, whiteflies, peach aphids, thrips, these are relatively common pests that can be controlled by pesticides.

A variety of different pests and diseases often occur, which have a serious impact on the yield and quality of peppers, thus greatly reducing the economic benefits of pepper growers. What are the manifestations of pepper planting that are most afraid of pests and diseases? How to prevent it?

Let me share that answer with you. The main manifestations are dark green leaf lesions, and rapidly expand, so that part or most of the leaves are soft rot and easy to fall off, the stem or fruit infection also produces dark green spots, the stem turns black brown from the branches, the disease part shrinks, the plant withers and dies, this disease is commonly known as "death fast". The main manifestation of pepper disease is caused by frequent pathogen activity in a high temperature and high humidity environment, which is a basis, and it also occurs when there is continuous precipitation and the drainage of the whole plot is not very good.

It comes out at night and lays its eggs on the young leaves, stems and stalks of the pepper plant. After hatching, the larvae damage the young leaves and young stems, and begin to borer the fruit after the second instar, and burrow holes in the fruit stalk to bury into the pepper fruit to eat the flesh paper placenta. Pepper grows well adapted to the soil, but is not drought or waterlogging.

Planting peppers requires a loose soil with ventilation and good moisture, and it is especially necessary to grasp the planting density and drainage and irrigation facilities in the field when planting and cultivating.

Control methods: Poplar branches, sweet and sour liquid attractants, and black light can be used to trap and kill adults. It can also be sprayed with biological insecticides, such as BT emulsion and powder, when the larvae are used.

However, it is important not to use organophosphorus highly toxic pesticides to prevent poisoning after ingestion. First, before planting peppers, choose organic fertilizers suitable for pepper growth. Second, after planting pepper seedlings, strengthen field and fertilizer and water management to improve the disease and insect resistance of pepper seedlings.

Third, the rational use of residue-free pesticides and biological pesticides to prevent and control pepper from pests.

Generally, the use of copper noble (other organic copper, inorganic copper preparations), dimetallin, carbendazim, methyl tobuzin and other agents of the solution for root irrigation, combined with root water when transplanting, watered once after the live tree, watered again before the flowering period, can basically prevent this disease, of course, except for the plots that have been stubble for many years.

If the pepper grows insects, you can spray the insect. If it is a home farm, it can be caught with disposable gloves or tweezers, and if there are more of them, it can be sprayed with pepper water to kill insects. You can choose plots with good light conditions, high and dry terrain, and good drainage.

Reasonable dense planting, high-lying wide and narrow row cultivation, and application of rotting organic fertilizer. Timely pruning, reasonable thinning, reasonable fertilization.

In the prevention of pests and diseases, pepper needs to keep the rhizome developed, and the focus should be on the allocation of nutrients, seedling hoarding, water control, and deep rooting before planting, so as to facilitate the cultivation of strong seedlings and reduce the incidence of diseases.

When controlling pests and diseases, peppers should keep their root system well developed. Before planting, we should focus on nutrient allocation, seedling storage, water control, and deep rooting to cultivate strong seedlings and reduce morbidity.

Pepper is the most common vegetable and condiment in our lives. Although it originated in Mexico, it has been cultivated more and more in China since its introduction. In recent years, there has been an increasing demand for chili peppers in the market due to more and more people liking to eat spicy food, but many vegetable farmers are often worried about chili pepper pests and diseases, because chili pepper pests and diseases are more serious than diseases, which have a great impact on the quality and yield of chili peppers.

What are the common pepper pests? How can it be prevented? 1.

Cotton bollworm. Cotton bollworm is one of the most common pests in the growth process of peppers, affecting not only the growth of peppers, but also other nightshade vegetables.

Cotton bollworm mainly eats the buds, flowers and fruits of peppers, and also harms the leaves, young stems and buds of peppers. After eating, the buds will appear yellow-green and fall off naturally 2-3 days after eating. The larvae of the cotton bollworm also eat the fruit of the pepper.

Although it will not cause the fruit to fall off immediately, it will cause rain or germs to enter the fruit, causing the fruit to rot or fall off, which will seriously affect the quality and yield of peppers. Control method: Cotton bollworm eggs will be latent in the soil for overwintering, and when the temperature rises in the second year, the larvae will crawl out of the soil and invade vegetables.

Therefore, when planting peppers, you should avoid rotating with other nightshade vegetables, dig deep in the soil and dry it for 2-3 days before planting, and you can eliminate some cotton bollworm eggs.

During the pepper growth season, according to the insect forecast, the branches of the cotton bollworm that lay more eggs are cut off during pruning, and the eggs are taken out of the garden and burned. During the peak oviposition period of cotton bollworm adults, drugs such as karyotype polyhedrovirus and BT emulsion can be sprayed to kill cotton bollworm adults. The enlargement period of pepper fruit is the most serious period of cotton bollworm.

In addition to the effective control of cotton bollworm with chemical drugs, the phototaxis of cotton bollworm can also be used to trap and kill adult worms with black light. Aphids. Aphids are not only the most common pests during the growing season of peppers, but they are also the pests that have the greatest impact on most vegetables.

Under the influence of aphids, the internodes of pepper leaves and branches become shorter and bent, the leaves are deformed and curled, and the whole plant becomes weaker and shorter, which not only leads to the decline of pepper yield.

It can also spread other viruses that cause pepper disease. Control methods: Aphids can not only infect peppers, but also affect the growth of other weeds.

In order to reduce the number of aphids, the weeds in and around the pepper vegetable patch should be removed in time to reduce the number of aphids. Since aphids mainly attack the folds of the heart leaf or the back of the leaf of the pepper, when spraying the drug with aphids, it is necessary to spray the drug accurately on the heart leaf and the folds on the back of the leaf to achieve the desired effect. In order to prevent the occurrence of aphids, silver-gray mulch can also be used when planting peppers to prevent winged aphids from sneaking into the pepper fields and causing peppers to be infected with aphids.

If you want to control pepper aphids, you can only control them by spraying pesticides, and there is no other way to buy this insecticide at agricultural supply pharmacies.

Remove the surrounding weeds, burn them, prepare some insecticides, properly clean up the areas with many insect pests, enhance ventilation, and meet the needs of light.

Clean the countryside. Remove weeds in and around the field to reduce the source of insects.

Silver-gray film mulching cultivation. The characteristics of aphids with negative tropism to silver-gray are used to achieve the purpose of avoiding aphids and preventing diseases.

Need. Because my family grows chili peppers, if you don't prevent insect pests, then chili peppers will suffer a lot of insect infestations, and the yield will be seriously reduced, so you need to control insect pests.

Peppers also need to be protected from pests and diseases during the planting process, because pests and diseases will also occur during the planting process of peppers, affecting the final yield and quality.

Yes, this is also very prone to diseases, very easy to suffer from insect attacks, this must be prevented in advance.

Symptoms: Roots, stems, leaves, and fruits can be damaged. The seedlings are infected and the base of the stem is water-soaked and rots, and they die quickly.

Adult plants are also mostly infested from the base of the stem, and the lesions are water-soaked and dark green, and then become brown and slightly concave, and the cortex under the epidermis becomes dark brown. Any part of the stem can be infected, the lesions often spread around the stem, and the upper tissues wilt and die rapidly. The leaves are paper-thin, light brown, cracked and detached; When the humidity is high, the surface of the lesion is white.

The stem pathogen can enter the fruit through the fruit stalk, forming dark green, water-soaked lesions, white on the top, and the diseased fruit turns brown and shrunk after soft rot and hangs on the branches.

Control methods: select disease-resistant varieties; Implement crop rotation; Pepper is rotated with cruciferous, leguminous or onion and garlic vegetables for more than 3 years; Strengthen management. Use disease-free soil to raise seedlings, cultivate high ridges, cover with plastic film, prevent water accumulation in the field, and remove weeds and diseased plants in time; Chemical control.

In the early stage of the disease, you can choose to use Fengqia Genbao 10g+ partner to irrigate the roots.

Control method: seed treatment. Pre-soak with cold water for 1 2 hours, then soak in 55 warm water for 10 minutes, and then put it in cold water to cool and then germinate and sow seeds.

The seeds can also be soaked in cold water for 10 12 hours, then soaked in 1% copper sulfate for 5 minutes, or soaked in 500 times of 50% carbendazim wettable powder for 1 hour, and then neutralized the acidity with plant ash or a small amount of lime after fishing, and then sowed. Strengthen field management. Reasonable dense planting, formula fertilization, timely ventilation of the shed, avoid high temperature and high humidity, pay attention to drainage, timely remove diseased leaves, fruits and residues, and implement 2 3 years rotation with non-homogeneous vegetables.

At the beginning, the base of the seedling stem appeared water-soaked lesions, soon developed upward, and turned yellow-brown, the young stem shrunk after the diseased part lost water, or became linear, causing the seedling cataplexy, the cotyledons at the time of lodging have not yet withered, and the furrow surface of cataplexy disease develops rapidly from point to piece, often causing dead seedlings. Control measures: choose disease-resistant varieties.

You can choose five-leaf eggplant, seven-leaf eggplant, purple round eggplant, bulb red, purple eggplant and bamboo silk, etc.; Seedbed soil treatment: when sowing, the seedbed is watered once permeable, 9-10 grams of 40% pentachloronitrobenzene per square meter, 40 kg of fine dry soil is added, and 1 3 is taken to lay the bottom, and 2 3 is sown to cover the seeds; Pesticide control: the temperature and humidity of the nursery shed and room are easy to develop when the temperature and humidity are suitable, until the true leaves grow and the young stems are plugged.

You can choose to use Fengqia root confirmation water spray.

Blight, powdery mildew, gray mold, downy mildew, sclerotinia sclerotiorum, umbilical rot, aphids, thrips, etc.; Regular sterilization, regular disinfection, good protection and pest control, use special tools and potions.

The first point is that black insects will appear when planting, which is very terrible, and must be paid attention to, the second point will appear white pests and diseases, which is very terrible, and the third point will also appear that the black hole is all rotten, and the fourth point should be protected accordingly, and some corresponding drugs can be sprayed for soil renovation.

Common diseases of eating pepper are blight, blight, powdery mildew, etc., and powdery mildew can be sprayed with more than 1000 times of the solution. Aphids are controlled with 40% fenvalerate.

will appear. Improve the structure of pepper planting. For example, in an area, intercropping is used to plant peppers, which can prevent the spread of pests in a large area; For example, if peppers are not planted in a plot for several consecutive years, this method can effectively control the eggs of pests, such as aphids and leaf mites, and reduce the anti-growth of insect pests.

Another example is to replace the variety of peppers in time. Grasp the dynamics of the agricultural market and choose pepper varieties that are resistant to pests and diseases.
