What to do if cherry infective gum disease?

Disease control: Liangguoan 400 times + silicone;

Pest control: 10% imidacloprid 600-800 times + 48% chlorpyrifos 600-800 times + pyridoxine 800 times.

Remarks: Supplement zinc and boron and prevent frost injury; Improve the fruit setting rate, prevent and control microlobular disease and yellow leaf disease.

The "flowing oil" you are talking about should be the flow gum disease that can occur in stone fruit trees such as peaches, apricots, plums, and cherries. There are two types of causes: non-infectious and infective.

Non-infectious gum disease of peach trees: mainly caused by frost damage, frost damage, pests and diseases, hail damage, excessive or insufficient water, improper fertilization, excessive pruning, excessive fruiting, soil clay weight or soil acidity. To prevent and control the disease, we should first strengthen cultivation management, increase tree potential, pay attention to orchard drainage, increase organic fertilizer, improve soil, prune reasonably, and reduce trunk wounds.

At the same time, it is necessary to prevent insect injuries in time, especially peach aphid and peach tumor aphid. In winter and spring, the branches are painted white to prevent frost damage and sunburn. In early spring, the diseased part is scraped off, and the wound can be coated with Baumé 5 degree stone sulfur mixture, and then coated with white lead oil or coal tar to protect it.

Peach Tree Infective Gum Disease: It is a disease caused by a fungus of the subphylum Phylum Phylum Phylum, which mainly damages the branches. There are two peaks in one year, from late May to late June and from early August to mid-September.

Control method: Spray 5 Baumé stone sulfur mixture or 50% antibacterial extra wettable powder 800 times before bud germination in early spring to kill the germs after wintering, spray 1 time every 10 days, and spray 3 times in a row.

From late March to early April, spray 4000-5000 times of 72% agricultural streptomycin sulfate, spray 1 time every 7 days, spray 2-3 times, and you can also use 800 times of 50% antibacterial special wettable powder or 800-1000 times of 50% carbendazim, 1000-1500 times of 50% methyl tobuzin, spray 1 time every 10 days, spray 3-4 times.

In the vigorous growth period of peach blossoms (between May and June), use 800 times of 50% antibacterial special wettable powder, 500 times of 70% mancozeb wettable powder or 80% anthrax Fumei wettable powder 800 times liquid spray, spray 1 time every 7-10 days, spray 3-4 times, the above pesticides are best used alternately. In winter, it is necessary to prune the diseased and dead branches, burn them in a centralized manner, and spray the stone sulfur mixture for tree disinfection.

Let's talk about how to deal with the cherry tree gum flow, the treatment is very simple, clean up the dead skin of the gum flow part!

<> gum disease is a comprehensive disease of cherry, which is extremely common and has complex causes, and it is difficult to completely do so. Below we will introduce to you how to prevent and treat cherry gum disease, and what drugs are used for cherry gum disease** for reference.

1. Strengthen the cultivation and management of orchards, enhance the disease resistance of the tree, increase the application of organic fertilizer, avoid partial application of nitrogen fertilizer, cultivate the potential of strong wild beard trees, and improve the stress resistance of the tree.

2. Guest soil planting.

3. Try to avoid causing wounds.

4. To protect the tree, the comprehensive control of pests and diseases should be strengthened during the growing season, and attention should be paid to minimizing the mechanical damage to the tree. Pay attention to the protection of trees after natural disasters, especially after hailstorms. In winter and spring, the branches are whitened or antifreeze is applied to prevent sunburn and frost damage.

5. Improve the soil, timely cultivate and loosen the soil, drain and prevent waterlogging, and improve soil aeration.

First, use a knife to scrape off the dry glue and old warped skin of the diseased part, and use a knife to make a few cuts, and squeeze out the glue, and then use ulcer + penetrant such as: silicone, etc., and apply it (note that the smearing area should be greater than 1 2 times the area of the terminal disease), and apply it again at a serious interval of 7 to 10 days.

The most suitable period for coating is when the sap begins to flow, which is the starting period of the flowing gum, and the number of plants is small, which is convenient for prevention and control and reduces the nutrient consumption of the tree. In the future, it will be found and launched with manpower smear prevention and control.

It can be combined with the prevention and control of other diseases, spraying 600 800 times liquid + penetrant for prevention. In the early stage of the peak of the outbreak of gelatinous disease, spray 600 800 times of Liangguoan (add penetrant if necessary) in combination with the local disease situation, spray 1 time every 7 10 days, and spray 2 3 times in a row.

1. When the condition is severe, an appropriate amount of quantitative penetrant can be added for better effect.

2. The rain within four hours after spraying needs to be re-sprayed.

3. If there is a slight precipitation, it is a normal phenomenon, which does not affect the efficacy of the drug.

4. This product should be placed in a cool and dry place in its original packaging, avoid direct sunlight, and handle it gently during handling and transportation. Before the onset of the disease, it can be diluted and sprayed with 800 1000 times of Liangguoan, and the drug is used once every 15 20 days.

**: Gum-flowing disease is an important disease of cherry copy, and its symptoms are divided into two types: dry rot type and ulcer type gum flow. The dry rot type mostly occurs on the main trunk and main branches, the initial lesions are irregular, dark brown, the surface is hard, often causing gelatin, and the later lesions are elongated, dry and constricted, sometimes cracked around, and the surface is densely populated with small black spots.

In ulcerative gum disease, the diseased part of the tree is resinous but does not flow out immediately, but remains between the xylem and the phloem, and the diseased part is slightly raised, flowing with the sap, and flowing out of the skin hole or wound of the diseased part. At first, the disease is colorless, slightly transparent or dark brown, and hard. Dry rot gum disease is caused by the subphylum Ascomycetes, Staphylococcus sinensis, conidia and ascospores are transmitted by wind and rain, and can be infected from April to October, mostly by wound invasion, and the disease is severe in the early stage.

The fungus is a weak parasitic fungus, which can only invade weak trees and weak branches, and the weaker the tree, the more serious the disease.

Solution: Cherry trees avoid waterlogging, apply more organic fertilizer and spray at the same time, spray 3-5 degrees of stone sulfur mixture before germination, the effect is very good, and spray perforated flow gum net and methyl tobuzin in the growing season.

Gum disease is an important branch disease that occurs in cherries, due to the complex causes of the disease, it is not easy to completely prevent and control, the light tree is weak, and the heavy branch is dead.

Symptom. Diseased trees begin to excrete gum in the wounds of the branches and dead tissues in the branches. After the gum flow, the diseased part is slightly swollen, the cortex and xylem become brown and rotten, and other miscellaneous fungi are saprophytical, resulting in the weakening of the tree, and the branches die in severe cases.

Symptoms of cherry gum flow.

Prevention and control methods. Strengthen management. Choose sandy loam soil or loam soil with good air permeability and fertile soil to plant cherry trees. Increase the application of organic fertilizers to prevent drought and waterlogging disasters and improve the resistance of trees.

It is necessary to avoid frostbite and sunburn, thoroughly control branch pests, and avoid mechanical damage. When pruning, large wounds should be reduced, and large shearing saws should be applied with scar healing agent to protect the wound from infection.

Manual curettage. For the branches that have been diseased, they should be scraped and treated thoroughly in a timely manner, and 5 Baumé stone sulfur mixture should be applied.

Pharmaceutical prevention and control. 10 days before germination, spray the whole tree with 60 times the liquid of Baiming 98 Ling, focusing on the main stem and diseased spots; In mid-July, during the ** period of high-temperature pathogens after the rain, the whole tree was sprayed with 150 times of Baiming 98 Ling; 10 20 days after harvesting, the main stem was sprayed with 60 times of Baiming 98 Ling. If you usually find gum disease, you can use Baiming 98 Ling 2 3 times liquid to smear the lesion at any time, or spray the lesion directly with a small pot.

Prevention and control of large cherry gum disease: First, when pruning in winter and spring, use Picon smear to apply the saw edge and wound in time to prevent bacterial infection. The second is to spray the branches with 300 times Piconoctamine acetate after fruit picking and before germination to kill overwintering bacteria.

The third is the branch flow gum disease, do not scrape the rubber block, use Piccomoctamine acetate to apply the rubber block and one centimeter around it, apply it 2-3 times at a time, with an interval of 7-10 days, apply it twice, the glue flow stops immediately, and the rubber block dries up and falls off by itself. Fourth, when applying basal fertilizer in autumn, it should be mainly based on well-rotted farmhouse fertilizer, apply more compound microbial fertilizer, pay attention to the application of soil conditioner (wotianjia is also called), reduce the amount of chemical fertilizer, and water after application, which is conducive to fertilizer decomposition and root absorption, improve soil, fertilize soil fertility, inhibit pathogens, and improve plant stress resistance.

How to deal with gum disease in cherry trees.

Dry gum flow is a phenomenon that often occurs in cherry trees, when the gum flow is severe, it can cause yellowing of leaves, death of twigs, weakening of the tree, and even the death of the whole plant. There are many causes of gel disease, such as frost damage, insect pests, diseases, hail disasters, mechanical damage, etc.

To prevent and control the gum flow of cherry trees, we should start from avoiding wounds and injuries caused by the tree, prevent and control dry boring pests in time, minimize the wound of the tree body in the process of cultivation and management, apply white to the branches to prevent frost damage and sunburn, strengthen the drainage of the orchard, and reduce the degree of gum flow. For the branches that have flowed gum, they should be scraped in time, scraped clean, and the holes should be coated with fungicide.

Hello! The pathogenesis of large cherry gum disease is complex, with both fungi and bacteria, which are intertwined, which makes it more difficult to prevent and control, which is also the main reason why the disease is difficult at present.

Prevention and control measures: 1It is not advisable to choose acidic soil, sandy soil, waterlogged and drought and water-deficient plots to build large cherry orchards.

2.Choose disease-resistant varieties.

3.Take care to remove weeds. Minimize wounds, and do not cut large saws when pruning to avoid pulling branches to form cracks.

4.Timely control of red-necked beetle and silverfish to reduce insect damage.

5.To prevent frost damage and sunburn, the diseased branches should be scraped and treated thoroughly, and the wound should be smeared with 10 parts of quicklime, 2 parts of stone sulfur mixture, 1 part of salt, and a little vegetable oil, mixed with water.

Whitening of tree trunks is carried out in late autumn and early winter to prevent the occurrence of winter frost damage. Production method and use method of whitening agent: 10 parts of quicklime, 2 parts of stone sulfur mixture, 1 part of salt, a little oil (animal and vegetable oil), 2 parts of clay, 40 parts of water, stir evenly and then paint the trunk white.

The whitening part is mainly the base of the trunk (the height is appropriate in m) and the middle and lower part of the main branch of the fruit tree. Whitening is done twice a year. They are carried out after defoliation and in early spring, respectively.

The condition for determining the whitening time in early spring is that the earlier the better, and the newly planted trees should be coated immediately after planting.

6.Pesticide control: Before germination, spray 3 5 degrees of stone sulfur mixture, and you can continue to scrape off the lesions during the growing season, and apply the stone sulfur mixture.

Combined with the prevention and control of peach brown rot and other diseases in the growing season, spraying began 7 10 days after flowering, spraying the tree body with 75 chlorothalonil wettable powder 800 times, spraying once every 10 15 days, spraying 2 3 times. Agricultural streptomycin was selected for bacterial pathogens, and agricultural streptomycin was sprayed 3 times during the defoliation period in autumn and early spring.

How to deal with gum disease in cherry trees.

1. The reason for the gum flow of cherry trees.

1. Weak growth: The gum flow of cherry trees may be due to the poor growth, the tree is relatively weak, and the nutrient cycle of the tree body is poor, which leads to insufficient nutrient distribution.

2. Root diseases: It may also be caused by root diseases. Its root system has root rot, root cancer, root rot and other diseases, causing the root system to become weakened, and it will also lead to the phenomenon of gel flow.

3. Bacterial diseases: When cherry trees are infected with bacterial diseases, they will also cause gum flow. Because once infected, the branch part will be infected, and the necrotic part will gradually increase, and the phenomenon of flowing gum will occur.

Second, the best method of cherry tree gelatin.

1. Strengthen management: When managing cherry trees, we should pay attention to strengthening fertilizer and soil management, especially to apply more organic fertilizer, phosphorus and potassium fertilizer, and control the amount of nitrogen fertilizer in the middle and late stages, so as to enhance the tree potential, thereby improving the disease resistance of trees.

2. Reasonable pruning: During the management period, reasonable pruning should be carried out according to the growth of the tree to ensure a stable tree potential. After pruning, the cut should be coated with a bactericidal agent to promote wound healing, prevent glue flow, and reduce infection.

3. Clear the garden in time: clear the garden in time after picking fruits every year. If the tree is not managed after harvesting, it cannot be well maintained. Nutrition should be supplemented in time to ensure that there is enough nutrient reflux and reduce gel flow.

There are two types of gum flow diseases: physiological gum flow and infectious gum flow, and physiological gum flow mainly occurs on the main trunk and main branches. After the rain, the gum becomes a brown hard amber gum block in contact with the air, and the diseased part becomes brown and rots after being infected by saprophytes, resulting in the tree becoming weaker and weaker, and in severe cases, it causes dead trees, and the rainy season is seriously ill, the older trees are seriously ill, and the young trees are lightly ill. Infectious Flow:

It is mainly harmful to the branches. The pathogen infects the branches of the year, mostly from the wound and side buds, and there is a nodulous protrusion centered on the skin hole, which does not flow gum in that year, and has the characteristics of latent infection, and the tumor skin cracks and overflows the glue in the following year, and a large number of fusiform or round small black spots are born on the surface of the diseased part in the later stage of the disease.

Control measures: 1 Enhance tree potential, increase the application of organic fertilizer and biological fertilizer, spray phosphorus and potassium fertilizer, control nitrogen fertilizer 2, scrape the diseased part at the early stage of the disease, and then apply octybactalin or copper preparation or medium biomycin.
