Many people don t know about mosaic disease, what is jujube mosaic disease?

The flowering of the jujube tree is due to the jujube tree suffering from jujube madness, also known as jujube tree lobble. Jujube madness is a disease of the jujube tree that is transmitted by a fungal virus. The symptoms are that when the jujube tree sprouts and blooms, the stamens will grow small leaves, and the small leaves will grow and form a ball.

Diseased jujube branches do not bear jujubes,Analyze the cause of the disease. What happened in our whole village was the jujube trees of me and my neighbors"Jujube madness"Relatively severe. After observation, there are more arborvitae planted in our schools and village committees, and the "jujube madness" of this piece of jujube trees has occurred severely.

The pathogen of jujube madness multiplies in large quantities in the sieve tube, affecting the normal transportation of nutrients in the tree, resulting in atavism of flowers, making the flower stalk become a branch, the sepals and petals become leaflets, and a small flower develops into a small branch, which is manifested as a cluster of branches and leaves, causing a large number of clumping branches to the tree body, mosaic disease is spread by leafhoppers and aphids, so it is prevented in time with insecticides before flowering, and the drugs are insecticides, imidacloprid, avermectin, etc., and the trees on the edge of the orchard should be controlled together, and insecticides and fungicides should be used alternately when the disease occurs.

Jujube mosaic disease, also known as mosaic virus disease, is a viral disease, which is caused by mottled yellowing of leaves, and is transmitted by aphids, psyllids, thrips, and planthoppers. To prevent and control jujube mosaic disease, it is necessary to kill both the virus and the pests that spread the virus. When the jujube tree blooms, the jujube tree grows new branches, and the new branches bloom again, but much later than the first stubble.

When the dates are ripe in July and August, the dates on the new branches are still green. In fact, there is no harm in new branches.

Jujube mosaic disease is a serious disease second only to jujube madness in northern jujube trees, and it has a tendency to worsen year by year. According to the research of Ma Runnian, a teacher at Shanxi Agricultural University, jujube mosaic disease is a disease caused by mycoplasmid infection. Due to the sensitivity of mycoplastids to tetracycline, the prevention and control of disease-transmitting insects, in early May, the germination and leaf development stage of jujube trees, the peak of the first generation of adult emergences of poison-carrying insects such as Chinese rhododium leafhopper, can be used to solve 3000 times of 50% Leferin emulsifiable concentrate on jujube orchards and other nearby orchards and trees.

You will find that the leaves of the jujube tree have become a lot smaller, and there will be some yellow-green spots, there will also be bulging symptoms on the surface, the leaves will be some distortions, and there will be some oily feeling, which will affect the photosynthesis of the jujube tree.

Jujube mosaic disease is a disease of jujube trees in northern China, which has gradually worsened in recent years, and is caused by a mycoplasmid infection.

This is a common condition on the jujube tree, the leaves will all fall off, and the fruit will sprout a second time, and there will be spots on it.

Treatment method of jujube tree lobular disease: spraying medicine, jujube tree lobular disease is also known as jujube madness, it mainly resists the jujube tree to absorb nutrients in the soil, usually it is caused by planthoppers, thrips.

and other pests. When the disease occurs, it is necessary to spray dichlorvos every 7 days.

Thiametoxam, clothianidin and other agents for 1 month.

Pruning branches: It is also necessary to prune the diseased branches of jujube trees in time, which can not only effectively reduce the consumption of soil nutrients, but also prevent pathogens.

Infection of other branches and leaves, making the situation more severe. When severe, it suggests that the jujube tree can gradually regain its vitality, and can also increase the yield of jujube fruit, which is conducive to the healthy growth of jujube tree.

Provide enough light: The jujube tree is a fruit tree that loves sunlight. Generally, after spraying on the jujube tree, the jujube tree should be placed in a sunny and ventilated environment for propagation. In sunlight, it can promote the rejuvenation of the jujube tree and can also make the branches and leaves of the jujube tree more lush.

Top dressing: If the jujube tree suffers from lobular disease, nitrogen, phosphorus and potassium compound fertilizer can also be applied in time. Often, top dressing potassium compound fertilizer can also be used instead of decomposed organic fertilizer. Compound fertilizer is beneficial to increase the disease resistance of jujube trees, promote the growth of jujube trees in the soil, and prevent excessive occurrence of jujube trees.

Causes of lobular disease in jujube trees: Jujube trees are affected by lobular disease, usually caused by planthoppers, thrips and other pests, and may also be deficient in nutrients. Lobular disease is one of the serious diseases of jujube trees in China.

If the disease occurs, the results will be few in the second year. Diseased trees are also known as "gong jujube trees". 3-4 years after the onset of the disease, the whole plant will die, which poses a greater threat to production, and it spreads throughout different jujube fields in the north and south of our country.

Among them, Guangxi, Yunnan, Sichuan, Chongqing and other cities have been more seriously affected. In recent years, Meishan, Sichuan and Guanyang in Guangxi.

The jujube area has been outbreaks one after another, and it is becoming more and more severe. It spreads through the roots, and the incubation period of the disease ranges from 25 days to more than 1 year.

Overall, golden silk dates are more susceptible to disease, and the disease is more severe in arid, barren land and widely managed date orchards. If diseased trees are found, they should be removed in time to avoid the spread of the disease and serious illness. Diseased trees can be controlled by digging up diseased trees in the area every year.

The lobular disease of jujube trees is mainly transmitted by diseases and insects such as planthoppers and jujube gall mosquitoes, and loblet disease may also occur due to lack of nutrients. Lobular disease can be prevented by spraying, pruning branches and leaves, etc.

It may be due to the lack of timely hydration and fertilization, the failure to spray pest removal drugs, or the change in temperature, which can cause leaf disease.

The cause of this is infection with a virus, which is usually caused by poor nutrient delivery due to excessive rain or improper fertilizer application. For example, the application of raw chicken manure accelerates the weakening of the tree, and the yellow leaves shrink and the root system is aging.

Jujube madness is severe in jujube orchards where the soil is arid and barren, the management is extensive, and the trees are weak. At the same time, the occurrence of the disease is also related to the variety of jujube trees, the altitude and slope of the jujube orchard.

In the main producing areas, we should promote intercropping of jujube grains as much as possible to prevent the contact between diseased plants and healthy roots, so as to prevent the spread of pests and diseases, and carry out effective ring stripping, which has the effect of blocking the operation of the source of disease in the body of the tree. Before the jujube tree blooms and after flowering, spray the trunk with 1000 times of 40% dimethoate pesticide acetamiprid, and 500 times of 25% West Paris wettable powder to kill the propagating leafhopper.

Jujube leaf disease is also known as jujube madness, which will inhibit the digestion and absorption of nutrients in the soil by jujube trees, which is usually caused by whiteflies, planthoppers, jujube gall mosquitoes and other pests. It is also necessary to cut off the diseased branches of the jujube tree immediately, which can reduce the consumption of nutrients in the soil layer, and also prevent pathogenic bacteria from spreading to other branches, making its condition more serious, promoting the gradual restoration of the vitality of the jujube tree, and increasing the fruit production of the jujube tree, which is beneficial to the growth and development of the jujube tree.

Jujube trees with lobular disease should be prevented and treated according to the disease status. The small leaf disease of the jujube tree is actually jujube madness, which is also a viral disease spread by whiteflies, planthoppers, jujube gall mosquitoes and other stinging and sucking insect pests. If some branches are diseased, you can cut off the diseased long branches; If the disease is caused by the whole plant, there is no need to prevent and control it, and it is recommended to cut it off as soon as possible to prevent and infect other plants.

Use a hand saw horizontal ring to see the tree pole up to 1 mm deep into the phloem one circumference, with a spacing of 30 50 cm, and saw 4 or 5 times to prevent the source of disease from spreading downward. If the disease plant is mild, after cutting off the arbuscular branches, antibacterial drugs such as tetracycline and oxytetracycline are introduced into the phloem, which is curative, but it cannot be **, and it needs to be injected again when attacking.

For the small leaf disease of the jujube tree, it can be carried out by pruning the branches and adding fertilizer**, pruning off the bad branches and leaves on the jujube tree, and supplementing the corresponding materials.

It is best to choose chemical agents**, and also control the concentration of chemicals, pay attention to the spraying time, and also remove the problematic branches and leaves.

It is necessary to prune the branches and leaves in time, and also disinfect and sterilize in time, kill pests and diseases in time, and use fertilizer reasonably.

To deal with the selection of chemical agents, it is necessary to control the concentration of chemicals, pay attention to the spraying time, and drop the branches and leaves.

You can look for this.

The leaves will appear yellow-green mottled and sometimes black spots, which will cause the leaves and stems to wither and the fruits to fall off, which will seriously affect the yield of the plant.

The leaves become smaller, the leaves become deformed, the mesophyll begins to yellow, the texture of the whole leaf is uneven, and it is easier to grow on the young leaves.

After the leaf is infected, it will begin to become smaller, with obvious twisting and deformity, and at the same time, there will be some spots on the leaf, causing the leaf to turn yellow-green, especially on some delicate leaves. Even grafting can be infected with mosaic disease, and the greater the number of pests, the more severe the disease.

Many people don't know about mosaic disease, what is jujube mosaic disease?

Good afternoon, I am happy to answer for you, the way of infection is mainly through insects to absorb the sap of the diseased tree and then fly to the good jujube tree to absorb the sap infection. When the insects absorb the sap of the arborvitae tree and then absorb it on the jujube tree, they will infect each other. Jujube tree sedan chair ride should be jujube mad branch bending disease, it is the same disease as the "phoenix nest" closed (leaf cluster branches) on the sycamore tree, the leaf cluster branches on the wattle strip, etc., jujube madness mainly occurs after flowering, the main manifestation is that the flower changes leaves, the peduncle is extended, the main bud germinates abnormally, mosaic disease is spread by leafhoppers and aphids, etc., so it is prevented in time with insecticides before flowering, and the drugs have piercing, imidacloprid, avermectin, etc., the trees on the edge of the orchard should be prevented together, and insecticides are used when the disease occurs, Fungicides alternate.

It seems that it is because of the temperature that has caused a certain mosaic infection, so many jujube trees have such a disease.

There was no protection against viruses, and at the same time there was no selection of disease-resistant varieties, and there was a lack of management skills, regular watering, and no good fertilization management.

Jujube mosaic disease** is caused by the extremely high temperature outside, or there are some parasites or fungi, which can cause jujube mosaic disease.

Even when the weather is still relatively cool and windy, because at this stage, it is easy to cause some germs to be blown to other jujube trees.

If the surrounding environment is relatively humid and there is no simple treatment in the field for a long time, then such diseases are prone to occur in this case and will affect the yield.

It is easy to occur in a cold and damp environment, and it is also easy to occur when encountering some pests and diseases, and it is also related to the management of water and fertilizer.

In warm conditions, it is especially easy to appear, and at this time the virus multiplies very quickly, so it is particularly easy to occur.

Jujube mosaic disease is also known as jujube mosaic virus disease, what are the hazards of jujube mosaic disease? What is the cause of jujube mosaic disease? How to prevent and control jujube mosaic disease?

The following farming gang will be introduced in detail for the reference of netizens. 1. Symptoms and hazards of jujube mosaic disease After jujube trees are harmed by mosaic disease, the leaves of jujube trees become smaller, and the leaf surface appears yellow and green with fine fragments, which first appear at the tip of the leaves, and then expand to the whole leaves. The surface of the diseased leaves of the affected jujube tree is uneven, wrinkled, distorted, translucent, yellow and green flowers and leaves, and the photosynthetic ability is affected, and generally does not cause defoliation.

2. Transmission routes and causes of mosaic disease in jujube trees Mosaic disease is mainly caused by dry weather, leafhoppers and aphids, and the spread of mosaic disease is mainly through leafhoppers and aphids. Grafting can also spread mosaic disease. 3. Prevention and control methods of jujube mosaic disease 1. Strengthen orchard management, increase organic fertilizer and potassium fertilizer to jujube trees, avoid partial application of nitrogen fertilizer, and irrigate or drain jujube orchards in a timely manner.

2. Prune the jujube trees scientifically to improve the ventilation and light transmittance in the garden, which can reduce the breeding of pests. 3. When purchasing jujube seedlings, avoid using diseased plants. 4. Impose the prevention and control of orchard pests to prevent the spread of diseases.

From the germination period of jujube trees in late April, spraying pests to control pests, leafhoppers can be used 50 phosphine emulsion 1000-1500 times, or 80 dichlorvos emulsifiable concentrate 8 ()0-1000 times, or 50 thiophos emulsifiable concentrate 1000-2000 times, etc., with 10 imidacloprid wettable powder 2000-3000 times or 50 aphid anti-aphid wettable powder 1500-2500 times liquid. Generally, the interval between spraying is 10 to 15 days. If you have a better way to prevent and control it, please leave a message below to tell us, and thank you for your support.
