What s going on with the white frost of the moon flowers?

Seasonal flowers. Whitefrost may be infected with powdery mildew.

If the moon flower is infected with powdery mildew, it is necessary to cut off the diseased branches and leaves in time to avoid the spread of the disease, and then spray 200 times of the high-lipid film for prevention and control, and then put the moon flower in a cool and ventilated environment, and spray carbendazim around the plant.

Powdery mildew can cause leaf wilting and scorching of the plant's leaves, and the plant will not be able to bloom properly.

Treatment method of powdery mildew in the moon season:

1. Prune as soon as possible: once the rose is infected with a disease, it should be pruned as soon as possible. It is necessary to cut off all the leaves with white powder, and some dry branches should also be cut off to reduce the pathogen and avoid the aggravation of the disease and the transmission to the healthy branches and leaves.

2. Spraying drugs: After pruning treatment, drugs should be sprayed, and Bordeaux liquid can be sprayed in the initial stage.

or stone sulfur mixture.

Take precautions. Once infected, powdery mildew should be sprayed to control powdery mildew and avoid the spread of the disease and hinder growth. In addition, management should be strengthened in the later stage.

3. Later maintenance: the plants should be planted in a place with good ventilation environment, and the humidity should be well kept warm and moisturized, and the humidity should be controlled. During the growing season, fertilizers should be applied frequently to promote vigorous growth and improve disease resistance.

In addition, it should be exposed to the sun more often, and it must not be placed in a cool and damp place to avoid reinfection.

Powdery mildew, powdery mildew is a fungal disease that harms flowers such as roses and roses, and spreads in mid-to-late May when the first infection spreads. After the damage, a layer of white powder grows on the leaf surface and tender shoots, and the leaves turn yellow and fall off when it is severe, which seriously affects the growth and flowering of the plant.

The prevention and control methods should strengthen cultivation management, pay attention to soil moisture and timely watering; Reasonable fertilization, nitrogen fertilizer should not be too much, potassium and calcium fertilizer should be appropriately increased to enhance plant growth and maintain a robust plant, which itself resists the invasion of miscellaneous bacteria in natural cultivation technology.

Prune and shape in a timely manner, remove diseased shoots and leaves, and improve ventilation and light transmission conditions between plants. Indoor potted plants should be placed in a well-ventilated and well-lit place. In winter, the indoor temperature and humidity should be controlled, and ventilation should be paid attention to at night.

Habits of the moon flower.

1. The moon flower has strong adaptability, cold and drought resistance, and the soil requirements are not strict, but the micro-acid sandy loam soil rich in organic matter and good drainage is the best.

2. Prefer the environment with sufficient sunshine, air circulation, good drainage and shelter from the wind, and proper shade is required in midsummer. The optimum temperature for most varieties is 15 26 during the day and 10 15 at night. It is more cold-tolerant, and enters dormancy when the temperature is below 5 in winter.

If the high temperature lasts for more than 30 in summer, most varieties will have less flowering, lower quality, and enter a half-rest state.

3. Some varieties can withstand low temperature of 15 and high temperature of 35; When the temperature lasts above 30 in summer, it enters semi-dormancy, and the plant grows poorly, although it can also give birth to buds, but the flowers have few small petals, the color is dull and dull, and it loses its ornamental value.

Don't ignore the long "hoarfrost" of the moon season, if you don't deal with it in time, you will be left with flower pots.

Frost on the leaves of the flowers is powdery mildew, and after the flowers are diseased, they need to be sprayed with potassium permanganate solution on the leaves**. The hoarfrost on the moon flowers may be caused by the environment being too closed, so when cultivating the moon flowers, it is necessary to open the windows frequently to ensure air circulation, in addition, it is also necessary to give appropriate astigmatism irradiation, and every sufficient amount of nitrogen fertilizer can be applied to make the moon flowers grow vigorously.

Frost on the mosaic leaves is powdery mildew, which is a fungal disease with a higher incidence in May and July every year. After the moon flower is diseased, it is necessary to spray the diluted potassium permanganate solution on the leaves**, and the effect can be achieved by applying it once every 1 week.

If the moon flower grows in a dense and impermeable environment for a long time, it is easy to breed germs, so it is necessary to place the moon flower in a ventilated environment for maintenance, and often open the window to ensure air circulation, in addition to the rainy season, it is necessary to reduce the amount of watering to avoid water accumulation in the soil, resulting in wilting of the branches and leaves of the moon flower.

The moon flowers are suitable for growing in a sunny environment, and in a sunny environment, the moon flowers will bloom more vigorously and the colors will be more vivid. Therefore, it is necessary to place the moon flowers in a bright place for maintenance, and give more than 6 hours of light every day to make the moon flowers grow vigorously.

The demand for nutrients is high during the growth process, and sufficient nitrogen fertilizer needs to be applied to it to make the branches and leaves grow vigorously. In the flowering period, it is necessary to change the application of phosphorus and potassium fertilizer to ensure that the fertilizer is sufficient, so that the rhizomes of the moon flowers can grow vigorously and have stronger disease resistance.

It is powdery mildew. Powdery mildew is a worldwide disease that harms plants such as roses, roses, and roses. The fungus infects the leaves, flowers, and shoots of the moon.

In early spring, the leaves of the diseased buds are covered with white powder on both sides. The leaves shrink and roll back, thicken, and gradually dry up and die, becoming the source of primary infection.

During the growing season, the leaves are infected, and small white pink spots appear first, which gradually expand into round or irregular white powder spots, and in severe cases, the white powder spots are connected to each other. At the onset of young shoots and petioles, the lesions are slightly enlarged and the internodes are shortened. The flower thunder is covered with a layer of white powder, shrunken and withered.

Mild buds produce misshapen flowers.

Because: infected with powdery mildew.

Cause: Caused by poor ventilation, and the infection is severe.

Prevention and control: 1. Ventilation.

The ventilation of the environment is the key element, and there needs to be enough light every day of growth, and keeping it in a place with full sunlight can help sterilize the flowers, and also promote the release of moisture, reducing the humidity of the environment and the accumulation of water in the pot.

2. Watering. The fungus is in a high humidity environment to harm the flowers, to water the flowers to choose a brighter time period, and watering should try to avoid watering directly on the leaves, if the morning has been watered, then do not water again at night, strictly according to the condition of the soil to adjust the number of watering.

It's a bug! Hurry up and get some medicine back! At the Flower, Bird and Fish Market, there are medicines that specialize in killing them! Don't wait any longer, it's too much more expensive, and it's going to pose a threat to the life of the flower.

White frost grows on the leaves in the moon season, and powdery mildew is prone to occur in spring, which cannot be ignored.

Disease, can it be opened**?

The appearance of hoarfrost on the leaves of the moon flower is usually caused by powdery mildew infection. Powdery mildew is a fungal disease, the incidence is relatively high in May and July, the first symptom of the disease is that there is a layer of white powder on the leaves, whether it is an old leaf or a new leaf, it will be eroded by the disease.

If it is not treated, it will soon affect the photosynthesis of the leaves, resulting in yellowing and falling of the leaves. Therefore, in the early stage of the disease, it is necessary to spray carbendazim or potassium permanganate solution for sterilization.

Powdery mildew prevention:

Enhanced ventilation: Powdery mildew is more likely to spread in poorly ventilated environments, especially at night, so it is best to place it outdoors in a well-ventilated location. If the plant is maintained indoors in winter, it is necessary to remove all the diseased leaves that are not in good condition before entering the room to avoid infecting other healthy leaves.

Timely isolation: After the detection of infected plants, it is necessary to isolate them in time, because the rate of fungal multiplication and spread is very fast. If you don't treat it in time, there is a high chance that one tree will be cured and the disease will be contracted again.

There is hoarfrost on the leaves of the moon flowers, it is likely to be infected with powdery mildew, the disease has the highest incidence in May and July, you can spray carbendazim solution as soon as possible to treat, and enhance the ventilation of the maintenance environment, isolate it from other plants, appropriately increase the time of seeing the light, and pay attention to the humidity in the environment is not too high.

1. The cause of white frost in the moon season.

The appearance of hoarfrost on the leaves of the moon flower is generally caused by the infection of powdery mildew, powdery mildew is a fungal disease, the incidence is relatively high in May-July, the initial symptom of the disease is another layer of white powder, whether it is an old leaf or a new leaf, will be eroded by the disease.

If it is not treated, it will soon affect the photosynthesis of the leaves, resulting in yellowing and falling of the leaves, so it is necessary to spray carbendazim or potassium permanganate solution for sterilization in the early stage of the disease.

2. Measures to prevent powdery mildew.

1. Strengthen ventilation.

Powdery mildew spreads more easily in poorly ventilated environments, especially at night, and it is best to store it outdoors in a well-ventilated location. If it is winter, it is best to remove all the diseased leaves that are not in good condition before entering the room to avoid other plants being affected.

2. Maintain the environment.

The humid environment is easy to cause diseases, especially after the rainy season, a long time warm and humid environment will be more conducive to the occurrence of diseases, usually in the maintenance of the maintenance should pay attention to the maintenance of it in a slightly moist position, at the same time pay attention to water and fertilizer management, during the flowering can be sprayed Yanwo potassium dihydrogen phosphate can make the flower color more pure, beautiful, while improving the resistance of the plant.
