Honeysuckle problem for help master diagnosis, honeysuckle disease and prevention

Your honeysuckle was originally growing very well on the balcony to bloom, you suddenly changed the environment, it can not adapt to the good because it has strong vitality, did not immediately fall off the leaves, but after the flower, the leaves fell off, and put back on the balcony just to adapt, and infected with fungi, so the new leaves fell again, and the traces of disease are clearly seen at the tips of your leaves, this is what you should find! This honeysuckle was infected by a fungus and suffered from brown spot, because there is no leaf back**, it is not easy to determine whether there is powdery mildew, but no matter what disease can be determined to be infected by the fungus, it is necessary to spray fungicides, optional carbendazim, use according to the instructions, right, stems, leaves, reverse front should be sprayed, once every 7-10 days, 3-4 times in a row, the medicine mixed with water should be used up at one time, and the excess should be used to irrigate the roots. I wish you success in raising honeysuckle!

Based on my years of experience in breeding, I feel:

Your honeysuckle due to the change of environment, it can not adapt to the good because it has a strong vitality, did not fall off the leaves immediately, but after the flower, the leaves fell off, and after putting it back on the balcony, it was just about to adapt, and it was infected with fungi, so the new leaves fell off again, and the traces of disease were clearly seen at the tips of your leaves, which you should find! This honeysuckle was infected by a fungus and suffered from brown spot, because there is no leaf back**, it is not easy to determine whether there is powdery mildew, but no matter what disease can be determined to be infected by the fungus, it is necessary to spray fungicides, optional carbendazim, use according to the instructions, right, stems, leaves, reverse front should be sprayed, once every 7-10 days, 3-4 times in a row, the medicine mixed with water should be used up at one time, and the excess should be used to irrigate the roots.

Leaf blight. Main symptoms after illness: leaf spot or dead leaves. After the occurrence of leaf blight, corresponding measures should be taken in time, and drugs can be selected. Then learn Dingjin wettable powder, or cool clean wettable powder, chlorothalonil, etc. To squirt, to destroy the sick.

Cataplexy. The main symptoms after the disease: the long-leaved bearded plant suddenly lodging, and the plant appeared black-brown.

Sudden illnesses are mostly caused by bacterial invasion. Bacteria invade the roots of the seedlings through the soil, causing the seedlings to fall like the ground. This is what we call cataplexy.

In addition, lignified plants and seedlings have different disease manifestations, most of them wilt, and if the growing environment is humid, pink bacterial colonies will be produced in the diseased plants. In view of the occurrence of seedlings, it is recommended to take drug treatment, spray thiophanate-methyl wettable powder, trichlorfon and other agents, and disinfect. Due to the contagious nature of cataplexy, in order to reduce losses and control the disease better, diseased plants should be treated in time to prevent infection of healthy plants.

All diseases should be prevented from the start. Therefore, in the early stage of planting, it is recommended to disinfect the soil to kill germs. Seedling blight is caused by sheath blight in the soil.

Most of the pathogens invade the root of the seedlings from the surface soil, and the diseased parts of the plants sink and shrink, and they are dark brown. Infected seedlings often lodging from the soil surface, resulting in cataplexy. If the seedling tissue has been lignified, then the diseased seedling usually does not lodging but shows symptoms of wilting. When the soil is moist, pink mold often forms in the diseased area.

Sunburn. Sunburn is caused by external causes. The symptoms of sunburn are cracks in the bark and wood that break easily in windy weather.

The main precaution is to pay attention to the planting density and not too far. and protect the trunk from the sun. A possible solution is to wrap the trunk with a straw rope for protection.

Honeysuckle, known as the "holy medicine" of sores and poisons: can honeysuckle fight viruses? What can be done?

Brown spot, a common mosaic disease of honeysuckle.

1. Harmful symptoms.

It mainly harms the leaves, and the yellow-brown spots appear on the leaves in the early stage of the disease, and several small spots fuse together in the later stage to form brown round lesions or irregular lesions. Under rainy and humid conditions, the back of the leaf has a gray-black frosty substance, and when dry, the middle part of the lesion is easy to crack. Cause the growth of the plant to weaken, and fall off when the disease is severe, affecting the growth and flowering of the plant.

2. Pathogenesis characteristics.

The disease is caused by fungi, the fungus overwinters on the diseased leaves, produces conidia in the early summer of the following year, and the conidia spread by wind and rain, generally starting from the lower leaves, and gradually developing upward, and the pathogen is cultivated rapidly in a high-temperature environment. The disease first occurs at the end of April, and the disease is more severe from June to August, and the plants with severe damage are severely affected, and a large number of leaves are lost in the early autumn.

3. Prevention and control methods.

1) Agricultural control.

Combined with autumn and winter pruning, remove diseased branches and buds, and burn them intensively or bury them deeply to reduce pathogens**. Remove diseased leaves at the beginning of the disease to prevent the spread of the disease. Strengthen, improve ventilation and light transmission, increase organic fertilizer on fertilization, control the application of nitrogen fertilizer, and apply more phosphorus and potassium fertilizers to promote the growth of trees and improve the disease resistance of plants.

In the rainy season, timely drainage should be carried out to reduce soil moisture to help control the occurrence of diseases.

2) Chemical control.

In the early stage of the disease, spray 800 times of 70% thiophanate-methyl wettable powder or 800 times of 70% mancozeb wettable powder, spray 1 time every 7-10 days, spray 2-3 times, pay attention to alternate rotation application, have better control effect.

Honeysuckle, also known as honeysuckle (scientific name: lonicera japonica). The name "honeysuckle" comes from the "Compendium of Materia Medica", because the honeysuckle flowers are white at the beginning and then turn yellow, so it is named honeysuckle.

The medicinal honeysuckle is a dried flower bud or flower with the first bloom of the honeysuckle family honeysuckle and the same genus. [1]

Honeysuckle, blooming in March, five out, slightly fragrant, pedicle with red, the color of the flower is white at the beginning of the flower, warp.

On the first and second days, the color is yellow, so it is called honeysuckle. And because of one pedicle and two flowers, two stamens poke out, in pairs, inseparable, like male and female accompaniment, and like mandarin ducks dancing together, so there is the mandarin duck vine called.

The most distinctive feature of this species is the large leaf-like bracts. It resembles honeysuckle in appearance, but the bracts of that species are narrow rather than leaf-shaped, the sepals are densely pubescent, and the twigs are densely curly pubescent, which is markedly different from this species. The morphology of this species varies greatly, both in terms of the hair perianth of the branches and leaves, the shape and size of the leaves, the length of the corolla, and the ratio of the length of the hair perianth and lip lobes to the tube.

However, all these changes appear to be more related to the ecological environment and do not show a correlation with geographical distribution.

Honeysuckle has been known as a good medicine for clearing heat and detoxifying since ancient times. It is sweet and cold and fragrant, sweet and cold and clear heat without hurting the stomach, and the aroma is thorough and can dispel evil. Honeysuckle can not only dissipate wind and heat, but also be good at clearing blood toxins, and is used for various heat diseases, such as body heat, rash, spots, heat poison sores and carbuncles, sore throat and other symptoms, all of which have significant effects.

It is recommended to ask where you bought flowers.

Honeysuckle is a medicine to remove fire, and if you feel uncomfortable in your throat, you can drink some honeysuckle to try.

Anemone yellow leaves can be caused by five reasons: if the temperature is too high, it needs to be moved to a ventilated and cool semi-shaded place for maintenance. If it is caused by insufficient light, it needs to be moved to a cool and ventilated place with sufficient astigmatism indoors to allow it to receive sufficient light.

If it is caused by too little watering, it is necessary to replenish water in time to ensure that the soil is moist. Due to insufficient fertilization, nutrients need to be replenished in time. If it is caused by insect infestation, it is necessary to use the drug according to the **.

Field management. Top dressing: In the first 1 to 2 years after planting, it is the development and finalization period of honeysuckle plants, and more fertilizers such as human and animal manure, plant ash, urea, and potassium sulfate are applied. After planting for 2 or 3 years, at the beginning of spring each year, more fertilizers such as animal offal fertilizer, manure, cake fertilizer, and superphosphate should be applied.

After the first stubble flowers are harvested, an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer should be chased to provide sufficient nutrients for the next stubble flowers. Every year after budding in early spring and when the first flowers are harvested, the ring ditch is watered with human manure and urine, chemical fertilizer, etc. 250g of each fertilizer was applied, and the order of the promotion of the vegetative growth of honeysuckle by fertilization treatment was as follows

Urea + Trim potassium dihydrogen phosphate can significantly increase the yield of honeysuckle, combined with vegetative growth and reproductive growth and fertilization costs, top dressing with urea + compound fertilizer is better.

Honeysuckle, also known as honeysuckle. Winter is sweet and cold, the smell is fragrant, sweet and cold and clear heat without hurting the stomach, and the aroma can be dispelled through evil. It has many effects and functions, mainly including clearing heat and detoxifying, relieving itching, antibacterial, anti-inflammatory and detoxifying, cooling blood and stopping dysentery, etc.

Drinking honeysuckle in water can clear fire and detoxify, reduce inflammation, enhance immunity, comfort and relieve annoyance, beauty and other effects, help improve the body's immunity, and enhance the body's resistance to germs. It can often be used to boil water and drink, and it can also be used to soak feet.

If the leaves are yellow, it is generally considered that the chlorophyll deficiency caused by the iron deficiency of the plant is considered to be the deficiency of chlorophyll, but the lack of nitrogen and water is not excluded.

Honeysuckle wilts.

First of all, do not over-shade, when cultivating honeysuckle, because its growth is relatively fast, the plant is more dense, if it is planted with other plants, excessive shade, will affect its growth.

The second is to replenish nutrients in a timely manner, especially after flowering.

In addition, it is necessary to pay attention to reasonable pruning, and cut off those branches that affect normal growth in time, so that they have good ventilation and light transmission, so that flowering will be better.

Finally, it is necessary to pay attention to winter, and be sure to protect the old branches of honeysuckle in cold areas.

Hello! Usually honeysuckle is very adaptable, sun-loving, shade-tolerant, cold-tolerant, also resistant to drought and moisture, the soil requirements are not strict, the root system is developed, the rooting force is strong, it is a good soil and water retention plant, hillsides, river embankments and other places can be planted. In shade, growth is stunted.

**On the surface, the stem skin of the plant is separated, and the internal color is black, which may be caused by poor overwintering management in the early stage, such as too dry in winter, damaged roots, etc., resulting in weak plant growth and attack by pathogens.

If the root system is normal, the damaged stem needs to be cut off and wait for new shoots to germinate after normal management. Disease prevention can be used with 65% zebsen 500 times dilution or tobuzin 1000 1500 times dilution, spray once every 7 days, 2 3 times in a row. From April to June, attention should also be paid to aphid damage.

FYI.
