What is the effective way to prevent grape rot and cankers?

If it's rotten fruit, bagged grapes, urine pockets will appear. It has a sour taste. After the granules decay, the place where the juice flows (fruits, stems, cobs, etc.) rots.

The most fruitful grains are the dried ones, and the dry grains are just the skins and seeds of the fruit. New Year's and flies spread quickly to mountain rot. Before grape bags, it is necessary to use bag medicine, in general, choose a suspension agent, etc.

Acid rot canker disease mainly causes particle breakup infection, so timely removal of cracked and decaying particles is key. The better effect of the agent is thiamine decapyrazole resid. White rot is a soil-borne disease that should be prevented by the first effective rainfall or irrigation after flowering.

The protective agent can choose Dasanyan 10 pyrazoxystrobin, and the ** agent can choose glucozole 10 cisalazole and coolamine. It is necessary to focus on the prevention of certain diseases. Grape acid rot, white rot and canker are all common diseases in the growth period, especially acid rot can cause some grape growers to give birth, so they need daily protection, but the causes of these three diseases are different, and the prevention methods are also different.

Grape acid rot. It is now arguably one of the most harmful diseases to grape yields, with losses of up to 30 to 80 percent in many orchards, and some growers are directly saving water. Prevention of obstetrics and gynecology** The first thing is to remove the cracks in the park in time to avoid the invasion and spread of germs.

Second, avoid the use of hormones, eat fruits reasonably, maintain a reasonable distribution of ears, and avoid overcrowding and cracking of fruit trees. In the process of fertilization, it is necessary to master scientific and reasonable fertilization methods, and it is recommended to use water and fertilizer, and do not use excessive nitrogen, so as not to grow grapes vigorously. Finally, 80% is to be used with pesticides, which is currently the only way to chemically prevent acid spoilage.

It claims to start from the base of the spike, 80% Bordeaux liquid 400 times, once every 10 days or so, sprayed three times in a row.

Grape canker grape canker is a fungal disease, which causes fruit rot, branch ulcer, cracking and branch wilting and death in severe cases, and the pathogen is mainly spread through rainwater, so the prevention is timely and the method should be comprehensive. Prevention and control of canker disease, remove the disease tissue on site in a timely manner, and destroy it in a centralized manner. Strengthen planting management, strictly control yield, control reasonable fertilizer and water, improve tree strength, and strengthen plant disease resistance.

Cover the shed room with film in time to prevent the grape plants from rain. Remove dead trees and disinfect the soil around them. Leave seeds with healthy branches and leave seeds with sick paper.

Cut the sick paper, destroy it uniformly, apply it to scissors, apply adhesive to the fungicide, etc., to prevent the invasion of germs. Strengthen management, rational fertilization, improve the potential of trees, strengthen plant disease resistance, and strictly control yields.

The best way to prevent it is to turn the land deep in winter, and then expose it to the sun for about 15 days, which can effectively remove pests and diseases, and you can also add more quicklime to the soil, or you can spray it with professional pesticides in spring, which can play a good role.

At this time, it is necessary to choose to spray pesticides in time, and to choose timely fertilization, such as phosphate fertilizer, potassium fertilizer, organic fertilizer or farmhouse fertilizer, must be watered in time, and it is necessary to do a good job of ventilation in time, weeding and insecticide in time.

A good way is to ensure that the sun is exposed, you can increase the planting distance between them, ensure that every root can receive sunlight, and then spray some pesticides to prevent it.

3 allAcid rot, infected by bacteria after cracking the fruit, has a sour taste, belongs to the secondary infection disease, and the key is to prevent white rot, gray mold, and anthrax. Cut off the diseased particles and use the necessary prevention and control, or use didichlorine or prochloraz iprodione + streptomycin, white rot, gray mold, anthrax, acid rot to prevent and control together. Fruit flies were found to be controlled with Fly Amine.

Grape acid rot is a secondary infection disease. The pathogenic bacteria are acetic acid bacteria, yeasts, and a variety of fungi infected from the wound. The degree of disease occurrence has a lot to do with the level and method of management.

Grape acid rot has become an important disease of grapes in China in recent years. Serious damage to orchards.

Prevention and control measures: 1. Select and plant disease-resistant varieties in areas with serious disease, and try to avoid planting varieties with different maturity stages in the same orchard.

2. The vineyard should be inspected frequently, and the diseased particles should be removed in time and buried in a concentrated manner; increase the permeability of the orchard and reasonable dense planting; Irrigation is not possible during the ripening of the grapes.

3. Rational use or non-use of hormone drugs to avoid peel injury and fruit cracking; Reasonable granulation thinning; Avoid over-tightening the spikes; Use fertilizers wisely, especially avoid excessive use of nitrogen fertilizers.

4. Early prevention and control of powdery mildew and other diseases, reduce disease wounds, use safe pesticides in the young fruit stage, and avoid too tight peel or peel injury. 80% must be used in combination with pesticides, which is currently the only way to control acid rot chemically. Spray 400 times of 80% Bordeaux solution at the beginning of the self-sealing panicle stage, spray once in about 10 days, 3 times in a row.

Need to use pesticides on time, must be reasonable watering, fertilization, so that you can be a good control, can leak the key to use some fungal pesticides. Tricks.

Spray pesticides on time, pay attention to the specific conditions of the soil, pay attention to the cleaning of weeds, pay attention to the selection of plant varieties, and generally choose some antifungal anti-fungal infection.

After the onset of the disease, you should go to buy medicine, quincitine is good to solve the problem, it is recommended to spray it 3-7 days after the bulking treatment

Hello, grape black rot prevention and control measures 1, seedling quarantine testing. Grape black rot fungus has an incubation period of up to 8-22 days on the leaves, so it can fully meet the conditions for long-distance transmission with seedlings. 2. Clear the garden in winter.

Grape black rot pathogens mainly overwinter on diseased fruits, diseased vines and diseased leaves, so we need to clean the garden in winter by cutting off diseased fruits, diseased shoots and leaves, and at the same time cleaning the ground diseased fruits and leaves, so as to reduce the existence of overwintering bacteria and reduce the incidence of disease in the next year. 3. Variety selection. In areas with high temperatures and humidity, such as those south of the Yangtze River, we need to choose some grape varieties from the Americas system to reduce the losses caused by the disease.

Among them, varieties such as Combar, Bei Alcohol, and Kabai are good choices. 4. Field management. We can bag the grapes after the fruit set is stable, the whole panicle and the thinning is completed, so as to reduce the damage of diseases to the fruit and reduce the value of the commodity.

In addition, it is also necessary to combine pruning to create good ventilation and light transmission conditions for the tree body, and improve the microenvironment in the orchard, so as to reduce the temperature and humidity in the orchard and create an environment that is not conducive to the germination of germs. 5. Chemical agents. Typically, 1:

1:200 Bordeaux liquid or 50% antibacterial special wettable powder 800-1000 times liquid for control, the specific spraying period is mostly concentrated in the three periods of grape flowering, flowering and fruit growth period. However, it should be noted that these agents should be stopped 15 days before the fruit ripening period to reduce the amount of pesticide residue in the fruit.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a happy mood in the morning!

There are many causes of grape rot, so it is necessary to eliminate grape rot, and then treat the symptoms, the more common is grape rot caused by excessive water and stagnant water. For this reason, it is generally necessary to reduce the humidity of the ground and drain the water in time after the rain, so as to reduce the incidence of this disease. Because there is stagnant water, it is easy to cause bacteria, and it is easy to breed mosquitoes, so it is naturally easy to cause grape rot, so for some low-lying terrain, it is indeed necessary to drain it in time.

Once the grapes are fruitful, they will choose to cover them in bags, so as to avoid the entry of many germs and mosquitoes, and can reduce the occurrence of grape rot。This practice is more commonly used, and now many growers will bag the grapes when planting grapes, so that the grapes can grow better, and there are no spots and can avoid some bacterial and insect invasion, which is a worthy choice and a good way to prevent the grapes from rotting. <>

The more grapes are not as fruit-bearing as possible, and too much load will lead to weak disease resistance, which will also affect the ventilation zone and light transmission, which will naturally lead to grape rot. Grape rot is indeed a very troublesome thing, so we must prune in time, for some grape trellis is not stable, we must choose to find some brackets to support, to prevent the vine from excessive load, and at the same time to expand a certain gap, to have a lighting and ventilation, so that it will be better. <>

The grapes must be at least 50 cm above the ground, if the grapes are too close to the ground, then it is easy to cause the grapes to rot, because it is easy for bacteria to invade. Planting is a technical work, you need to use more fresh food also need to pay more attention, if you can spread the mulch film that is the best, you should not pave the mulch film should raise the grapes to a judgment of caution, not too close to the ground, close to the ground is easy to have bacterial invasion.

Of course, it is also necessary to apply fertilizer reasonably to increase the disease resistance of the grapes in order to reduce the occurrence of this rot.

You should use the corresponding pesticides, then reduce the amount of water, lower the temperature, increase air circulation, and prune the rotten parts, so that you can **.

It can be ventilated frequently, or fertilized, or it can be written in a wide draft to carry out skillful use of pesticides, state filial piety or sufficient sunlight, so that it can be effective.

The roots should be cleaned up to a certain extent, and all the rotten parts should be pruned and excavated, and then the re-judgment should be given for planting, and the soil should have loose and good air permeability, and remember to control the environment every time.

<> the whole bunch of grapes rotted, it is likely that the grape is caused by gray mold or anthracnose. Botrytis cineris is susceptible to the disease during the flowering period and when the grapes are close to ripeness, especially in the environment of strong winds and rains, high temperatures, and high humidity in the field. At the beginning of the disease, the fruit has sunken lesions, which soon spread to the whole fruit and rot, and a gray mold layer grows on it.

Preventive measures: strengthen orchard management, avoid partial application of nitrogen fertilizer, prevent branches and vines from growing, clear ditch drainage to reduce orchard humidity, and timely prune diseased flower spikes to prevent the spread of viruses. In terms of prevention and control, it can be sprayed with 3o% Scarlett glue suspension LOOO times or 5o% Nongli Ling wettable powder 6oo-75o times or 48% gray lik wettable powder 8oo-looo times.

Grape anthracnose is mainly harmful to fruits, but also to the leaves, new shoots, inflorescences, etc., and is prone to high incidence after mid to late July. At the beginning of the disease, there are pinhead-sized water-stained russet round spots on the fruit surface, and the lesions are enlarged and concave, and the small black spots arranged in a dense wheel shape are densely formed, and the diseased fruit is easy to fall off after shrinking. The fruit is easy to crack in rainy days, and the fruit stalk is sunken and diseased.

Precautionary measures: Carry out grass cultivation or ground mulching, and bag after fruit thinning. In terms of prevention and control, you can use 5o% Cuibei 35oo times liquid or 45% charcoal withered net wettable powder looo times or lo% Shigao water dispersible looo times or 25% 100 grams of emulsifiable concentrate l5oo times liquid and other sprays.
