Do peppers need pest control during cultivation?

Peppers, whether old or young, may be infected by germs under the impetus of the wind. Powdery mildew is more likely to be prevalent in slightly drier conditions. At the onset of the disease, the small yellow spots on the front of the diseased leaves gradually expand into yellow spots with inconspicuous edges, and there are more pests and diseases of pepper in planting.

Pepper diseases include anthracnose, blight, virus disease, white silk disease, cataplexy disease, and blight. Only insect pests include small ground tigers, tobacco insects, aphids, tea yellow mites, etc.

Prevention and control methods:The selection of disease-resistant varieties, early control of aphids, strengthening management, controlling environmental conditions, and promoting the healthy growth of plants can reduce the occurrence of diseases to a certain extent. If the central disease is found, it will be uprooted in time to prevent the spread.

Prevention and control methods: seedbed disinfection, 30 grams of Fujia frost powder mixed with 18 kg of fine soil spreading, 30% seedbed, 70% covering. The seeds should be mixed with fludioxonil, and the proportion should be 500; 1。

Planting found is to remove seedlings in time, in sprinkling a small amount of plant ash, when planting peppers, scabs are more common, generally this kind of pests and diseases, peppers will fall a lot of leaves, and even peppers will fall to the ground, and during the growth period, will also fall flowers. In this way, if the assumption is not resolved, the scab cannot be **.

Before planting peppers, clean up all the remaining branches and leaves in the ground, and burn or remove the dead grass and new grass on the dam to eliminate the eggs and adults that overwinter. Chili scab This disease is also called bacterial spot disease, commonly known as defoliant blast. In addition to harming peppers, it also harms tomatoes.

1.Symptoms: Seedling leaves are diseased along the leaf veins, deformed, and demented.

There are many varieties of peppers, and there are some differences in size, appearance, color and spiciness. From the overall situation, most varieties of peppers are more warm and light-loving, and the amount of fertilizer required is also large; Pepper grows well adapted to the soil, but is not drought or waterlogging.

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.

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.

I think it needs to be protected, if the pepper is not properly maintained, then it may develop bacterial wilt, when the disease occurs, the top leaves of the pepper will wilt during the day, but on cloudy days or in the morning and evening it will return to normal, after 2-3 days, the leaves will remain normal, but the stem will wilt. The light case causes the seedlings to lodging in pieces, and the heavy ones cause the failure of seedling raising, which should be detected early and early.

After unearthing, the true leaves were infected by pathogens, and the incidence in production showed an upward trend in recent years, which had a great impact on the yield. The disease is characterized by rapid onset, rapid spread, short course of disease, difficult prevention and control, and great devastation.

Prevention first, comprehensive control" is the basic principle of pepper pest control. Under the premise of strengthening the selection of high-quality disease-resistant varieties, the implementation of crop rotation, deep ploughing of roasted soil, application of decomposed manure and other agricultural control measures, the coordinated application of physical, biological and chemical control measures. When using chemical control measures, scientific and reasonable selection of chemical pesticides with high efficiency, low toxicity, low residue and low lethality to natural enemies, and reasonable control of the safety interval of pesticides, combined with all aspects of the pepper production process, targeted comprehensive control.

The main disease of pepper is pepper blight, which may breed during the whole growth period of the plant, when the disease occurs, the base of the stem of the pepper is dark green water-soaked soft rot or cataplexy, sometimes black-brown, if the leaf is infected, there will be 2-3 cm round or nearly round dark brown lesions. The main disease of pepper is powdery mildew, which is caused by the fungus Lacecula sinensis in the subphylum Cysticosis, when the disease occurs, there will be a greenish yellow mottled edge on the leaves of the plant, and there will be a powdery substance on the back of the leaves, and the plant will have a leaf loss rod in severe cases.

In early spring, we need to remove weeds and leaf litter in the field in time, and do intensive treatment to reduce the population density of overwintering. Frequent weeding can reduce the damage. Pharmaceutical control: 80% dichlorvos emulsifiable concentrate 1500 times liquid spray heart leaf and leaf dorsal part.

The ** insect source base, in the winter seedling raising, need to remove the residual weeds, and fumigation of the residual adults, to cultivate "insect-free seedlings".

Attention should be paid to the growth of peppers, as well as regular watering, the production of germs in the soil, and the use of pest-control drugs.

It should be topdressed in time, organic fertilizer should be applied in time, ventilation should be ensured, and the density of control should also be paid attention to, and some pesticides to prevent insect pests should be sprayed in advance.

In the process of planting, it should be ensured that the first light of the yang boy who is full of mountain relatives can be irradiated, and a lot of insects can be killed through the irradiation of the sun, and more insecticides should be sprayed, so that a lot of small insects can be killed, and there will be no insect pests.

First of all, when planting, we must choose the soil is relatively fertile and wide land, and in the process of fertilization, we must choose farmhouse fertilizer, do not use the fertilizer bought outside, but also often water the plants, to prevent the occurrence of diseases and pests, if there is a small insect file silver situation, then we must spray insecticides in time.

Cotton bollworm , which is relatively common, must pay attention to the watering situation when planting, and need to use pesticides on time.

Pests such as toothworms, cotton bollworms, etc., may be encountered. When planting, pay attention to pests, pay attention to temperature, and pay attention to the salinity of the soil.

The first point will encounter black insects, this insect pest is very terrible, the second point will also encounter the green pest, and then it will bite, the third point planting must pay attention to this water not to water too much, otherwise it will not be good.

There are many pests and diseases that need to be prevented when growing peppers in greenhouses, such as virus diseases, blight diseases and gray mold, etc., such as cotton bollworm, tobacco goose, red spider and aphid. For these pests and diseases, different situations require different control measures. Disease prevention and control methods:

Beaceae vegetables can be rotated for 2-3 years to cultivate disease-free seedlings; Reasonable irrigation, drainage after rain, reduce field humidity; If the disease is found, clean it up in time, and apply decomposed organic fertilizer to reduce the spread of the disease. There is also the prevention and treatment of pharmaceuticals.

<> pepper likes warm temperatures, likes water and fertilizer, but high temperature is easy to get sick, too much water is easy to shih seedlings, fertilizer is easy to burn roots, so there are different management requirements at different stages of the whole growth period. Prevention method: Soak and disinfect the seeds respectively, and disinfect the seedbed soil.

**Method: If the disease still occurs after disinfection, then spray pesticides immediately, you can use 75% chlorothalonil wettable powder 400 times, once every 7 days, spray 2 3 times in a row.

Symptoms of pepper blight are brown to brown spots on the base of the stem and branches of the pepper. If the relative humidity in the field is high, the affected area indicates the appearance of white mildew and round spots on the leaves. Pepper virus disease is caused by cucumber leaf virus and tobacco leaf virus infection, which is carried by some aphids attached to the leaf surface of pepper, and in severe cases, it will lead to leaf necrosis, leaf loss, and fruit drop, and the virus has a high transmission rate and is relatively harmful.

It must be planted scientifically and fertilized reasonably. select excellent varieties that are resistant to viruses and disinfect seeds when sowing; Try not to rotate with nightshade vegetables and re-recommend planting. Do a good job in field management, remove the peppers and diseased leaves with pests and diseases in a timely manner, take them out for centralized destruction or deep burial, drug prevention and control

We can use 25% methamanine wettable powder and fine soil to mix well, sow in nutrient soil or spray 72% Prixic water solution 400 times after emergence, or 15% chlormephine water solution 700 times, spray 2-3 times, once every 7-10 days.

Some pesticides can be sprayed because pesticides can kill pests as well as their eggs.

This requires reasonable irrigation and spraying of corresponding pesticides, but it is necessary to pay attention to spraying every 7 days, and the frequency should not be too high.

If you want to grow peppers in a greenhouse, we need to control pests, we need to spray them with some insecticides, so that there will be fewer pests.
