There is something white powdery on the moon season, please tell us what is going on

It is powdery mildew.

1. Remove diseased leaves and branches

Powdery mildew will occur in the shoots or shoots, if not treated in time, it will slowly infect the branches or buds in the later stage, if not in time, the plant will die because of wilting, after this situation needs to be cut off in time to the infected leaves and branches, and it is necessary to separate the diseased plants from other plants.

2. Use fungicide to sterilize

After cleaning up the diseased leaves and branches, it is also necessary to spray fungicides in time to control them, such as carbendazim or potassium permanganate, which can be used every other week to ensure that powdery mildew is well controlled.

Causes of powdery mildew in season.

1. Air drying.

The long-term excessive dryness of the air is one of the reasons for the powdery mildew, this is because the dry air will make the leaves of the moon season slightly scorched, and it is easy to suffer from powdery mildew when the resistance to the outside world is reduced.

2. Poor ventilation.

In the process of growing in the moon, the branches and leaves will grow relatively densely, and the leaves are piled together without a good ventilation environment, and the leaves are easy to breed germs and cross-infection.

3. Lack of prevention.

No matter what the plant will inevitably encounter some pests and diseases in the process of growth, most of these problems can be prevented and avoided, if the maintenance process is not regularly sprayed with preventive drugs for the month and season, it is easy to get sick, generally in the process of growth to do this kind of prevention, the month season will not be infected with the disease.

The white powder on the leaf surface of the moon flower is due to powdery mildew on the leaves.

Strong adaptability, bright flower color, when changing seasons, easy to suffer from powdery mildew, a layer of powdery objects will appear on the surface of the leaves, if not treated in time, the powder will spread rapidly, all the leaves will appear in the same situation, resulting in the gradual yellowing of the leaves, affecting the growth of the moon.

In the early stages of powdery mildew, yesRemove the infected leaves in a timely manner。If the disease is severe, yes50% carbendazim and 70% methyl tobuzin solution were usedAfter dilution, spray on the surface of the infested leaves, and then water and cure, and the disease effect will improve after a week.

Cultivation method of moon flowers:

1. Potting soil selection.

The soil for cultivating moon flowers should ensure that the nutrients are sufficient, loose and breathable, and the garden soil, Jikang ash, garbage soil, river sand and other mixtures are generally used. Flower pots should be planted in pots with strong ventilation and drainage.

2. Fertilizer and water management.

Sufficient fertilizer supply can make the moon flowers large in size, bright in color and fragrant. Watering is done every 2 to 3 days during the growing season to avoid excessive watering and soaking and rooting.

3. Light temperature.

The moon season is light-loving, and the breeding process must ensure that there are more than 6 hours of direct sunlight every day, and the light duration is extended in winter. The appropriate temperature for development is between 18 and 22, and frost damage may occur if it is lower than 5.

4. Scientific pruning.

When the plant grows to about 15 20 cm, it is necessary to top, which causes the side buds to erupt. During the flowering period, prune the decayed flower buds to control the flowering period of the moon season, so that they open naturally and prolong the blooming time of the flowers.

The moon season grows rapidly, in the case of too dense plant growth, the air circulation is poor, and the moon season needs to be properly pruned, and some diseased and dead branches can be removed.

First of all, we have to understand, what insect pests are prone to appear in the moon season, aphids and red spiders are the most common, some friends can't distinguish these insects, we can distinguish them by appearance, aphids we also call dense insects, is the most headache for us to maintain plants, this pest is mostly green, super strong reproductive ability, the temperature exceeds 12 degrees Celsius can survive, can hide on the back of the leaves to dilute the branches and leaves of the leaves, it is simply a big bad egg. If you want to be a red spider, as the name suggests, it must be red, and it is easy to appear in the balcony maintenance season.

Secondly, how do we get rid of these pests?

1. The most trouble-free way is to wash the leaves and wash away all the pests, these insects are afraid of water, and they drown as soon as there is water. We should pay attention when using high-pressure water guns, because the water pressure is particularly high, not against the flowers, and when washing the leaves, we must hold it with one hand, otherwise the leaves will be washed away, and the amount of water must be controlled.

2. Kill insects with bare hands, this method is more suitable for men, you can hold the toilet paper in your hand, and grab it directly with your hands after you see it, and then press them to death These little villains. But be careful not to pinch the blade, this method is more patient, you have to carefully check the back of the blade.

3. We can use pepper water or garlic water to water the flowers every time we water, this method is a more effective way to prevent it, but we should pay attention to the watering time, do not get the leaves, if you accidentally get the leaves, you should clean it with water in time. When we use it, we should dilute it first, and it should not be too thick.

4. Some friends like to spray laundry detergent solution directly on the leaves, this method is also good, but it should be noted that we must first water the moon flowers to prevent and absorb the laundry detergent solution. When using, you must pay attention to dilution, and the effect of some vinegar in the laundry detergent is simply excellent.

Although the moon flower is beautiful, but in the maintenance of the infestation will often receive small insect infestation, the so-called beautiful things everyone likes is a truth, we need to pay attention to prevention in advance, so is the fundamental way to solve the pest.

The flower buds and new leaves of the moon season have a layer of white powder, which can also prevent dark spots in one move.

It seems that it is the initial stage, and it will be laid first.

This is powdery mildew, which is easy to occur under damp and unventilated conditions, and there are medicines sold in flower and bird markets and pesticide stores that can be cured, and can also be purchased.

Powdery mildew, harmfulIf there is a white powder on the branches of the moon, it is infected with powdery mildew, which is usually found in soils with poor ventilation and high nitrogen content. If the breeding environment is too warm, there will also be such a disease, after the disease must be early, powdery mildew is a disease that spreads very quickly, with potassium permanganate.

Can. Powdery mildew is a plant-strong infectious disease, although it is not the most contagious among all the common diseases of the moon season, but after the onset of the disease, if we do not do a good job of effective isolation and put in place the best measures, the infection in a small area is very rapid.

If there is a white powder on the branches of the moon, it is likely that you are infected with powdery mildew, which is usually found in soils with poor ventilation and high nitrogen content.

If the breeding environment is too warm, there will also be such a disease, after the disease must be early, powdery mildew is a disease that spreads very quickly, with potassium permanganate.

The white flocculent material on the moon flowers may be catkins, and in the spring some catkins will fall onto the plants.

There are white flocculents on the flowers, and it is possible that there are red spiders on the leaves, which should be prevented as soon as possible after being found, spraying with water, or mixing water with vinegar to clean the leaves of the plants. There is also the possibility of powdery mildew, which should be sprayed with a professional agent. In addition, during the maintenance period, it is necessary to pay attention to ventilation and water control.

Precautions for monthly and seasonal maintenance:

1. Light: The growth of the moon season needs full light, and it should be as sunny as possible, and the shady environment will grow weak and not conducive to flowering.

2. Temperature: It likes a cool temperature environment, and is resistant to cold and heat. The suitable temperature for growth is between 5 degrees and 25 degrees, and the high temperature above 30 degrees for a long time will seriously affect its growth and even enter a dormant state.

3. Moisture: It requires the soil to be moist and the air humidity is also high, and the water should be replenished in time during maintenance, and the short-term drought environment can be tolerated, and if it is dry for a long time, it will affect the growth.

4. Soil: It has strict requirements for soil, which should be loose and fertile, slightly acidic and rich in organic matter, so the clayey calcareous soil is not conducive to the growth of the moon season. If it is a potted plant for 1-2 years, the potting soil should be renewed to meet its soil requirements.

5. Fertilization: more fertilizer is needed for flowering in the month, and sufficient base fertilizer should be applied in the early stage of cultivation, and thin liquid fertilizer should be applied every 10-15 in addition to the high temperature dormancy period.

。Solution: We should do a good job of prevention in the monthly season, choose varieties with strong disease resistance for planting, strengthen cultivation during maintenance, maintain a good ventilation environment, apply fertilizer reasonably, ensure the balance of nitrogen, phosphorus and potassium, enhance the resistance of plants, regularly remove dead branches and rotten leaves, and reduce the possibility of breeding bacteria.

When the infected leaves are discovered, the infected leaves are cut off in time and destroyed together. In the early stage of powdery mildew, you can spray 25 times of 1500 times of powdery rust solution, after the condition is serious, you can use 300 times dilution spraying with fast net, spray 2-3 times in a row, spray once every seven days or so, and completely remove it.

Causes: In addition to the possibility of powdery mildew infection in the monthly season, it may also be infected with insect infestations, which can also cause white powder to appear on the leaves.

Extended Information: Rosa chinensis jacq）：

Known as the queen of flowers, also known as "moon and moon red", it is an evergreen, semi-evergreen low shrub that blooms in all seasons Generally red or pink, occasionally white and yellow It can be used as an ornamental plant, but also as a medicinal plant, also known as the moon season. There are three natural varieties, and the modern moon season flower types are diverse, with single petals and double petals, as well as beautiful flower patterns such as high heart curls; Its colors are bright and rich, not only red, pink, yellow, white and other monochrome, but also mixed color, silver edge and other varieties; Most varieties are aromatic. There are many varieties of Yueji, there are nearly 10,000 species in the world, and there are more than 1,000 species in China.

The natural flowering period is from April to September [18], and the flowers are large, from the inside to the outside, showing a divergent type, with a strong aroma, which can be widely used in horticultural cultivation and cut flowers. The adaptability of the moon season is strong, cold hardy, drought resistance, regardless of ground planting, potted plants can be, suitable for beautifying the courtyard, decorating the garden, arranging flower beds, with planting hedges, flower stands, easy to cultivate in the moon season, can be used as cut flowers, used to make bouquets and various flower baskets, the flowers of the moon season can extract essence, and can be used in medicine. It also has good antifungal and synergistic anti-drug-resistant fungal activity.

Red cut flowers have become one of the must-have gifts for lovers and have become the subject of love poems.

If there is powdery mildew on the moon, you have powdery mildew.

1. How to treat powdery mildew.

Powdery mildew is mainly manifested in the whitening of the front and back sides of the leaves, and there are powdery spots, and when the disease is serious, there will be a large area of white spots on the leaves of the moon. Once you get powdery mildew, you can use baking soda to control it when the disease is mild. Baking soda is sodium bicarbonate, you can dig a spoon of baking soda when using, mix it with 50cm of water, and spray it every 2 days after mixing it thoroughly.

When spraying, pay attention to the amount of baking soda, rather light than thick, and spray water again an hour after spraying to avoid fat damage on the leaves in the moon season.

If you get powdery mildew in the month, in the case of serious disease, cut off the stems and leaves that are seriously damaged, and spray the plant with powdery rust for control. Because different brands of powdered rust may have different concentrations when used, it is recommended that you dilute and dispense according to the instructions for use of the purchased agent. When spraying powder rust on the moon season, it is also necessary to pay attention to the maintenance of environmental ventilation to avoid water droplets staying on the leaves for too long.

2. How to prevent powdery mildew in the moon season.

Powdery mildew usually occurs in the maintenance environment is stuffy and not ventilated, so if you want to prevent the occurrence of powdery mildew in the monthly season, you should usually pay attention to the ventilation of the maintenance environment. Usually you can cut some chopped onions, soak the chopped onions in clean water overnight, and then take the supernatant and spray them every half a month, which can also prevent the occurrence of various pests and diseases. Spray some pica foliar fertilizer to improve resistance to pests and diseases.

Although Yueji is a relatively easy plant to raise, there will still be various problems in the usual breeding, such as powdery mildew is more common, so how should it be, come and see Huahua.

1. Remove diseased leaves and branches

Powdery mildew will occur in the shoots or shoots, if not treated in time, it will slowly infect the branches or buds in the later stage, if not in time, the plant will die because of wilting, then after this situation, we need to cut off the infected leaves and branches in time, and we also need to separate the diseased plants from other plants, so as to ensure that other plants will not be affected by it.

2. Use fungicide to sterilize

After cleaning up the diseased leaves and branches, don't think that there is no problem, you also need to spray fungicides in time to control, such as carbendazim or potassium permanganate, you can use it, use it every other week, you can ensure that powdery mildew is well controlled.

3. Pre-occurrence prevention.

Generally, powdery mildew occurs in the summer when the temperature is high, and since we know the season of the disease, we can spray Tobuzin before the summer comes, and we can prevent the occurrence of powdery mildew in advance. Usual maintenance is followed by the application of potassium dihydrogen phosphate of fertile leaves, and prevention is carried out.
