Pepper pest control is very important, what are the pepper pest control methods?

Chili pepper is a very common vegetable in China, and for many people, chili pepper is an indispensable food in life. Not only can it be eaten as a vegetable, but it can also be used as a seasoning for dishes. Compared with ordinary vegetables, chili peppers are also more expensive, and chili peppers are very nutritious, so there are many farmers who grow chili peppers.

However, when peppers are planted, there will also be many pepper bugs that harm the growth of peppers. Peppers can develop the disease at the seedling stage and after maturity, peppers will appear oval brown patches in the early stage of the disease, and ring-shaped black-brown patches will gradually appear at the rhizome of peppers, and then they will slowly shrank and wilt. Therefore, in the period of pepper seedlings, it is necessary to spray with potassium dihydrogen phosphate to prevent pepper insects from using 36% thiophanate-methyl suspension for deworming in the early stage of the disease.

Moreover, in the seedling period of peppers, cataplexy and other posts often occur in the seedlings, after the pepper is sick, there will be some yellow water stains on the rhizome of the pepper, and then it will slowly dry out, and the pepper will also become atrophied, and the pepper will produce a large amount of lodging at this time. Peppers are also prone to anthrax, which occurs very frequently in summer and autumn, and if the surrounding environment is hot and humid and poorly ventilated when growing peppers, it will definitely lead to spots on the pepper fruits.

Pepper insects are very harmful to peppers, although peppers may taste spicy, but they will still grow worms. Pepper insects absorb nutrients from the pepper fruit, causing the pepper to wilt quickly. So when planting peppers, insect repellent is also very important.

If the rhizome of the pepper is damaged by insects, it will definitely cause a large number of peppers to wilt. If you want to spend healthy and delicious chili peppers, you must attach great importance to the prevention and control of chili pepper insects, and master scientific pest control methods. <

Chili pepper is a very delicious food, not for some people who like to eat spicy, it is true that basically every day is indispensable for chili peppers, so there are many farmers who grow chili peppers in these areas.

You can choose some pesticides mixed in the pepper land, you can also use pesticides to spray directly on the leaves of the pepper, you can also turn the soil frequently, water frequently, you can also rotate water and drought, do not use organic fertilizer that is not rotten, you can also use sugar trees to trap adults, put sweet and sour wine in a box according to a certain proportion, and you can also install black lights to trap and kill insects, these are very good control methods.

The most effective way to grow insects in pepper is to spray drugs to kill insects, and the more commonly used drug is imidacloprid. If it is a family farm, it can be solved in a more environmentally friendly way, and if there are a small number of pests, you can wear disposable gloves or use tweezers to catch them. If there are more of them, you can spray them with chili water to kill insects.

It can be controlled by pesticides, we must pay attention to the condition of the land, try to remove the weeds, keep the land clean and hygienic, pay attention to the amount of fertilizer used, and choose the right varieties for planting.

We must pay attention to the density of planting, we must pay attention to ventilation, we must also water in time, we must work in time for top dressing, and control the light intensity.

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.

The common diseases of peppers, the blight disease is widely distributed, and carbendazim solution needs to be sprayed in time. In the case of gray mold, it is necessary to remove the damaged leaves in time and spray the soil mold solution. Peppers suffer from anthrax, which can cause fruit to fall and require spraying with a multi-cleaning solution.

Root rot can cause rot of pepper roots, so water thoroughly every time to avoid stagnant water.

Blight can occur in the stems, leaves, and fruits of peppers, and will quickly erode the plants, and the damaged parts will turn black and rot. It is necessary to do a good job of soil drainage in the rainy season to ensure that the soil is dry and wet. Spray carbendazim solution once every 1 week, and the leaves will gradually recover after continuous spraying.

Botrytis occurs in the petal part of the pepper, causing the petals to rot and rapidly erode the fruit and leaves of the pepper. Peppers are infected with gray mold, which will appear as water-stained lesions with a layer of mold on the surface. It is necessary to remove the damaged leaves and fruits in time, and spray the soil mold solution in time for effective control.

Anthrax mainly eats away at the fruit of peppers, and during the rainy season, it causes small black spots on the fruit to gradually rot. When planting peppers, the seeds need to be sterilized and disinfected, the density needs to be controlled, and the air circulation needs to be paid attention to. At the initial stage of the disease, spray a multi-preservation solution once a week for effective prevention and treatment.

Peppers suffer from root rot, which causes root rot and fruit and leaves to fall off gradually. When growing peppers, the soil needs to be disinfected. Water the peppers thoroughly every time to avoid stagnant water.

After the onset of the disease, carbendazim solution should be sprayed in time for prevention.

What are the common pests and diseases when planting peppers <>? How can it be prevented? It takes a long time for peppers to be planted in the garden for several months, during which many diseases will occur, and the main diseases encountered in pepper cultivation and the prevention and control methods are now shared with you.

Dump disease and blight: pepper seedlings are prone to fall disease and blight due to high air humidity and other reasons, and the control effect is obvious with pyric (downy mildew hydrochloride) or chlormycolin. Viral Diseases:

Peppers cultivated in summer and autumn are highly susceptible to viral diseases due to high temperatures and low soil moisture content, so soaking seeds in 10% trisodium phosphate solution for 10 minutes can prevent viral diseases. High temperature and drought induce the occurrence and spread of viral diseases, and high temperature and rain often have the epidemic of viral diseases. If the diseased plants are found, they should be set aside outside the park and treated alternately with drugs such as hydrochloric acid-maringua, bacterium poison clearing, and photosynthetic virus.

Root rot and wilt: After the pepper is planted, it is very easy to produce root rot and wilt due to soil-borne pathogens. Prevent root irrigation with methyl tobuzin, dimetallin and other agents.

Blight: Blight is a common disease in pepper cultivation, and the diseased parts generally occur from the stems or branches. The drug is 64% alum, DuPont colo, etc., once every 7 days, twice in a row.

Physiological diseases: Pepper flower drop, fruit drop, and leaf drop (three drops) are very easy to occur in pepper production, and have a great impact on yield. The main cause of flower drop is the effect of low temperature on pollination and the elongation of pollen tubes, and the drought of soil and air can also cause flower drop.

High temperature, drought and high temperature rain and waterlogging make the root absorption capacity weak, which is easy to cause fruit drop and leaf drop. Prevent and keep the soil moisture not too large or too small, and keep the pepper temperature 25-30 degrees during the day and 12-16 degrees at night. Botrytis cinerea:

It is a common disease in the production of peppers, and it is used with Pythium, Sukelin or Kaiser. Clean up the sick body before administering medicine. In production, it is necessary to prevent excessive humidity and high planting density.

When planting peppers, the common pests and diseases during pepper planting are mainly cotton bollworm, aphids and beet armyworm. The main methods of prevention and control are spraying drugs, during the planting of peppers, the proportion of pesticides is adjusted, and the right time is selected to spray, so that the harm of pests and diseases can be minimized.

Wilt, powdery mildew, virus disease, blight, Verticillium wilt, these are the most common, we must use targeted pesticides, but also pay attention to the use of organic fertilizer, ensure the composition of organic fertilizer, do not let the nutrients too single.

Anthracnose, root rot, blight, powdery mildew, blight, silk. It is necessary to understand the law of disease, and at the same time, it is necessary to prevent and control it in advance, spray chemicals in advance, and choose varieties with strong disease resistance for planting.

1. Bacterial wilt: Before transplanting, apply 100-150 kg of lime or plant ash per mu to adjust the pH of the soil and inhibit the reproduction of pathogens. At the beginning of the disease, 300 times of 14% copper ammonia aqueous agent, 500 times of 77% wettable powder or 4000 times of agricultural streptomycin sulfate were used, once every 7-10 days, 3-4 times in a row.

If the diseased plant is found, it should be pulled out in time and disinfected with lime to prevent infection.

2. Anthranose: 50% mancozeb 800 times solution, 1000-1500 times of Shigao liquid or 3000-4000 times of Ai Miao liquid spray, spray once every 7 days, spray 2-3 times.

3. Aphids and viral diseases: 3000-4000 times of aphid lice net or 4-6 grams of Aksulji Xiaotai per mu mixed with 50-60 kg of water for aphid control is better.

Chili pepper is a common vegetable on our table, but it also has many diseases.

So, what are the pests and diseases of pepper? What are the symptoms and control methods of pepper diseases and pests? Let's find out together.

What are the pests and diseases of pepper and symptoms 1, bacterial wilt There are many diseases of pepper, such as bacterial wilt is one of them, when the disease occurs, the top leaves of the plant will wither during the day, cloudy days and sooner or later will recover, 2-3 days later, the leaves are green, but the stem is dry and wilted, and pepper is most likely to produce this disease in a hot and humid environment.

2. Pepper blight pepper is also prone to pepper blight, when the disease occurs, the stem base of the plant is dark green water-soaked soft rot or cataplexy, and the leaves may also be infected, with round or nearly round, yellow-green edges, dark brown lesions, if the fruit is infected, it will rot and wither.

3. Powdery mildew is also a disease produced by peppers, when the disease occurs, small yellow spots will appear on the front of the pepper leaves, and then it will gradually spread into green-yellow mottled edges, and the back of the leaves will have powdery substances, and when it is serious, the leaves of the pepper will all turn yellow and fall off.

4. There are many insect pests of peppers, such as tobacco insects, whiteflies and tea yellow mites, etc., these pests will absorb the juice of peppers and eat the leaves, resulting in the leaves of peppers withering and falling off, thickening and twisting and other undesirable phenomena.

Pepper pest control method 1, agricultural measures to select disease-resistant varieties and 2 3 years have not been planted with Solanaceae crops; Deep ploughing of frozen soil before winter, ploughing and raking in spring, cleaning the field for weeds, hidden dangers of diseases and insects; Seed treatment, cultivation of strong seedlings, full application of well-rotted organic fertilizer, formula use of chemical fertilizer; Implement ridge formation, intercropping, plastic film mulching, reasonable dense planting, planting in large and small rows, cultivating and weeding, and harvesting at the appropriate time.

2. Chemical measures for virus diseases: early prevention of aphids, spraying 500 times of 20% virus A wettable powder or 1000 times of plant disease emulsion, or zinc sulfate plus potassium permanganate plus potassium dihydrogen phosphate plus urea, once every 7 10 days, and 2 3 times depending on the condition.

Anthrax: Spray 500 times of 50% mixed sulfur suspension or 600 800 times of 70% thiophanate-methyl wettable powder, or 1400 1500 times of 50% benmonyl wettable powder, or 80% anthrax Fumei wettable powder 800 times at the beginning of the disease, once for 7 10 days, 2 3 times in a row.

Blight: spray and irrigate the roots with 50% methyl copper wettable powder 800 times or 70% ethylphosphomanganese zinc wettable powder 500 times, or 600 800 times of Galik water agent, and sprinkle more than 96% copper sulfate 3 kg mu before watering in the high temperature rainy season, and then water.

Underground insects: When preparing the land, 90% trichlorfon crystals should be mixed with soil or fried corn grits, wheat bran and green cabbage leaves should be sprinkled on the surface to trap and kill.
