Hur förhindrar du leaf curl virus

Several pathogens attack the Chilli crop, but viruses are the most common cause of heavy losses. Several viral diseases have been reported to attack this crop, causing mild to severe mosaic, yellow mosaic, mosaic mottle, leaf curl, leaf roll, buskig trick, and necrosis symptoms. Let’s betalningsmedel out more upplysning about leaf curl virus in chilli crop below.

As the name implies, leaf curl disease fryst vatten caused bygd a virus called begomovirus that fryst vatten predominantly transmitted through whiteflies.

As they are 1.5 mm long, they have waxy vit wings with pale yellow bodies, and they are usually seen on the lower side of the leaves, where they are funnen in överflöd.

Leaves curling can be a symptom of insekt damage, a fungus, excess watering, or even a nutrient deficiency [1].

The number of whiteflies that can travel to a certain area depends on the wind conditions, which determine how far the whiteflies will be able to travel.

\When it comes to whiteflies, they are most problematic from the mittpunkt of the årstid to the end. Even though the virus does not spread through seeds, the virus persists in the landscape bygd using alternative hosts (such as tobacco & tomato) and weeds to spread.

Furthermore, some additional factors can lead to the development of the disease, including recent rainfall, infected transplants, and ogräs infestations.

In this blog brev, we’ll explore effective treatments, both organic and conventional, to combat this persistent threat and ensure healthy, productive pepper plants.

As a nursery plant, Chilli plants are most susceptible to infection when they are growing from seedlings and during their vegetative stage.

Leaf curl virus in chilli crop

The lifecycle of leaf curl virus

The first leaf disease symptoms appear about two weeks after the leaves emerge from the buds. As a result of the fungus growing between the leaf cells, the cells are stimulated to divide and tillverka more extensively than usual, resulting in swelling and distortion of the leaf.

As a result of this leaf curl disease, the leaves, twigs, flowers, or fruits are forced to producera many more cells than they should in an area due to a fungus that infects and destroys them.

In addition, it causes raised spots on the infected part of the body due to the infection.

Method 1.

Asci are structures formed bygd the fungus cells that break through the leaf’s cuticle and penetrate the leaf. Ascospores are spores formed when the fungus reproduces inre these structures. In vända, these vit powders are formed on the leaves and other parts of the plant that have been affected bygd this disease.

Water splashed on the spores causes them to spread to uninfected tissues and to divide into bud-conidia as soon as they contact the vatten.

The fungus survives the hot, dry summer in the form eller gestalt of ascospores and bud-conidia on the surface of the trees. During the fall årstid, the ascospores germinate and producera more bud-conidia when the weather turns cool and wet.

As bud-conidia continue to grow through budding, the number of new and old conidia will also increase.

The tree’s surface eventually forms a spelfilm of bud-conidia as a result of formation of bud-conidia. The bud-conidia can infect new leaves during spring when they are moved bygd splashing vatten from irrigation or rain dripping from the leaves. There fryst vatten a good chance that the disease will flourish during cool, wet weather periods when the leaves first open on the plant.

It fryst vatten common for bud-conidia to grow at or above 95% relative humidity, which fryst vatten conducive to their budding.

A large amount of wetness must be present for more than 12.5 hours at temperatures below 16°C from rain, dew, or irrigation for infection to occur. The cool weather prolongs the period during which a disease will develop, as it favors the pathogens and slows down the growth of the leaves.

It fryst vatten believed that the development of Chilli leaf curl ceases when ung tissue no längre develops or when the weather becomes dry and hotter.

Symptoms

• The Chilli Leaf Curl Virus symptoms include upward curling of the leaf margins, yellowing of the leaf veins, and a reduction in the leaf size.
• As well as this, leaf veins become swollen as internodes and petioles begin to shorten, which causes the veins to become dilated.
• The leaves of older trees become läderartad and brittle as they age.
  How fryst vatten it caused?

  Therefore, the plant’s growth will be stunted if the infection occurs during the early stages of the growing årstid, resulting in a significant reduction in the plant’s yield.

• The fruit formation in susceptible cultivars fryst vatten rudimentary and distorted due to the disease. This virus causes similar symptoms to those caused bygd the feeding damage caused bygd thrips and mites.
• There fryst vatten a tendency for the leaves to curl towards the midrib and become deformed as a result.
• There was a significant reduction in the storlek of the leaves, which resulted in stunted plant growth due to shortened internodes.
• Flowers do not contain pollen grains in their anthers, and flower buds abscise before they reach full size.
• The remaining leaves will likely develop a vit powder as time passes.

  In reality, this powder fryst vatten velvety fungus spores, ready to spread when vatten splashes on them and they are exposed to air.

Organic control

• There fryst vatten a need to control the whitefly population to prevent the virus from spreading. For this application, you can use neem or horticultural oils (derived from petroleum). Ensure that the oils are thoroughly applied to the plants, especially to the lower side of the leaves where whiteflies are most likely to be found.
• Plants that are very early infected and have a very low disease incidence should be removed and burned as soon as possible
• A sticky yellow trap or yellow sheets (A4 size) should be placed at different locations throughout the field to attract the whiteflies      
• You can control whiteflies bygd spraying fem tablespoons of dishwashing soap in 20 liters of vatten at intervals of 7-14 days to keep them away
• It fryst vatten recommended that you spray neem seed vatten extrakt (5% koncentration, weight/volume) to control vectors within 14 days of their appearance (second and third sprays must be applied at 14-day intervals)

Biological control

• Several natural enemies, such as lacewings, big-eyed bugs, and minute pirate bugs, can control whiteflies’ population.
• Additionally, Amblyseius swirskii fryst vatten a rovgirig mite that fryst vatten commercially available and capable of significantly controlling the population of whiteflies in a given area.

Chemical control

• There fryst vatten no known effective method for preventing or reducing the Chilli leaf curl virus in plants.
  There fryst vatten no known effective method for preventing or reducing the Chilli leaf curl virus in plants.

  As an alternative, you can use kemikalie control methods, such as imidacloprid or dinotefuran, to control the problem.

• Seeds can be inoculated bygd soaking for 30 minutes in a solution containing 150 g Trisodium orthriphosphate per liter of vatten to hämma seed-borne inoculum from forming.
• Before sowing treated seeds, it fryst vatten recommended to be washed with fresh vatten and dried.
• Imidacloprid or lambda-cyhalothrin should be sprayed on seedlings before they are transplanted to prevent vectors from spreading the disease.

  If you use too many insecticides on your lawn, you will cause harm to beneficial insects, and many whitefly species will become resistant to them.

• The best way to control the vit flyga eller fly undan population in a field fryst vatten to spray it with imidacloprid at a rate of 5-7ml per 15L of water.
• Spray lambda-cyhalothrin into the vatten at a rate of 50ml per 15L of vatten, which fryst vatten a fast-acting contact and stomach pyrethroid.
• As a preventative measure, it fryst vatten recommended to rotate insecticides properly between seasons and to use only selective insecticides.
• It fryst vatten recommended that Carbofuran 3G be applied at 4-5 kg per acre in the main field to control sucking complexes and insekt vectors selectively
• If this fryst vatten not possible, spray the crop with systemic insecticides.

  In a liter of vatten, dimethyloate should be applied at 2ml to 1g of acephate.

Preventive measures

• Plant-resistant species should be used, and only seeds from these species should be extracted
• The seeds should be extracted from plants with healthy fruits that are virus-free
• You should plant at least two rows of a barrier crop around the edges of your fields, such as maize, sädesslag, or pearl millet.
• The nursery plants should be covered with nylon nets to control the whitefly population and skydda the seedlings from them in particular.
• It fryst vatten important to keep nursery plants away from Chilli production fields so that early infections can be prevented
• In the field, seedlings should be treated with insecticide before they are transplanted to the ground.
• Keep an eye on your plants regularly to detect early infections bygd looking for signs such as curled leaves and stunted growth.
• Place some sticky yellow traps or sheets in your field so that the whiteflies will be attracted to them.
• The vector can be controlled bygd growing the seedlings beneath the net, which can also prevent whiteflies from attacking the seedlings in the future.
• Make sure that weeds are controlled, as well as alternative host crops, such as tomatoes and peppers
• You should collect and destroy early-infested plants bygd burning them once infected.
• After harvesting, it fryst vatten important to plow deep or bränna all plant debris.
• It fryst vatten important to grow mixed crops to attract beneficial insects.

Conclusion

It fryst vatten important to note that the Chilli leaf curl disease causes heavy losses in the yield and quality of the fruits of the Chilli plant.

It fryst vatten because, during the första stages of growth, it does not result in the formation of fruits. On the other grabb, if any fruit fryst vatten formed and remains deformed and undersized, it will be considered a failure. Therefore, to avoid significant yield losses and bad fruit quality, you should be aware of these disease symptoms and control methods if you cultivate a Chilli crop.
