What is the name of the flower with white hairs on the leaves?

Is there a **? Isn't it? It's a goat's milk flower, but I don't know what its scientific name is.

There are thousands of creatures, too many, so let**, or more detailed, better.

1. White hairs on the leaves of roses may be suffering from powdery mildew.

The white stuff on the leaves of the rose is a white patch.

This condition is mostly caused by the discomfort of the growing environment provided. For example, if the plant is kept in a humid environment for a long time, coupled with poor ventilation and stuffiness, such an environment is easy to breed germs, which will infect the plant and lead to diseases. In the later stage, leaf spot, powdery mildew, etc. will gradually form, and there will be powdery powder and white spots on the leaves.

Second, how to treat.

1. Timely pruning: This phenomenon should be treated in time. Cut off all the leaves that have white powder on them. If some branches have become dry, they should be cut off and the diseased leaves and dead branches should be removed to avoid infection.

2. Replanting: After pruning, the plant should be taken out of the pot, and the root system should also be pruned, and the rotten roots and blackened roots should be cut off, and they should be disinfected. After that, prepare a new potting soil, which should be loose and breathable. The treated plants are then replanted in the soil.

3. Later maintenance: After planting, the plants should be placed in a well-ventilated environment, temperature control and moisturizing, do not rush to direct light, and then manage normally after resuming growth. Pay attention to the maintenance environment in the later stage, usually ventilate more, bask in the sun more, replenish nutrients in time, and choose Bika anti-stress and water-soluble fertilizer to avoid re-infection.

Why do potted roses grow white hairs on their leaves?

Many flower friends think that the leaves of the plants raised at home have white hairs on their backs, which are moldy and look like hairy fluff, and as soon as they let them go, the leaves will wither and wither.

Cotton bollworm. When the larvae develop, they secrete a white cotton wool-like wax substance, which is more common in April and July, and spreads quickly, hindering plant photosynthesis and causing leaf wilting.

Treatment: Prune the branches and leaves or sprinkle water to wash to increase the humidity of the plants, which can reduce the number.

Flower Friend Question: There are potted plants in the flowers raised at home.

The petiole produces a mass of white fluff the size of a grain of rice, which is not a cocoon that bears insects, and this white is not a fluffy caterpillar.

Is it? Does it affect other plants without affecting plant growth?

The plum insect is a very nasty pest that feeds on plant sap and is an east-winged insect, you know. Aphids.

It is the white fluff of one eye that contains wax that can be secreted to protect itself from rain. The excrement of the plum worm contains a lot of sugar, which is often sprayed on the leaves, causing the fungus to grow, and is a very nasty insect.

You can pinch them to death with your hands at first, but stick to it every day. Because bugs are small, they reproduce and grow quickly. Because if the killing speed is insufficient, it will be restored quickly.

Flower friends ask: There are white fluff on the branches and leaves of plant bonsai, white cotton balls or something, what is that?

If the plant or soil is not moldy, there is a high chance that the cotton scale insect will be blown.

Cotton bollworm is a very small, white, hairy parasite.

Plant sap can be absorbed, so that early deciduous leaves or branches do not grow well. Cotton bollworms usually hide in plant crevices or interlaced places, such as the back of leaves, under leaves, and even in the roots of plants.

Since puffs multiply very quickly, if they start to multiply, they should be chosen immediately (bamboo sticks or toothbrushes can be used). When tidying up the pots, keep them ventilated and pay attention to the presence of ants. (Ants are the drivers of powdery shellworms, carrying them to plants.) ）

It is very likely that the plant has pests and diseases, and the plant-specific insecticide should be used in time, evenly sprayed on the plant leaves, and can not be watered during the medication, otherwise the efficacy will be reduced, and it can be sprayed several times to consolidate it.

Mainly because there is no sunlight for a long time, and it may also be that there is too much moisture, and the drainage work is not carried out in time, so it will cause white hairs on the leaves, and it should be moved to a sunny place at this time.

Excessive evaporation of water, watering, not too much, put it in a place with cool air circulation for a few days, and breed it in a sunny place. Choose the right soil, which is loose, drainable, and aerating. Give it more than 4 hours of light every day.

It shows that the potted plant of this rose has some bacterial interference, and you can buy some chemicals to prevent and control it, which can play a certain role.

Summary. A: This plant may be a daffodil.

Daffodils are a perennial herbaceous plant with white hairs on the leaves and some small bubbles, and the flowers come in a variety of colors such as white, pink, and lavender. To grow daffodils, you must first choose a well-ventilated, well-drained place, where the soil is fertile, moist, loose, and with a pH in between. When sowing, you can sprinkle seeds on the surface of the soil, then gently press it with your hands, and finally water it with warm water to keep the soil moist, after the seeds germinate, keep the soil moist and avoid the soil being too dry, so as not to affect the germination of seeds.

In addition, daffodils prefer a warm and moist environment, so be careful to keep the soil moist and water regularly, but not in excess, so as not to cause too much water and affect the growth of the plant. In addition, daffodils like sunlight but not direct sunlight, so choose a semi-shaded environment to ensure the normal growth of the plant.

In addition, macro daffodils like sunlight but cannot be exposed to direct sunlight, so it is necessary to choose a semi-shaded environment to ensure the normal growth of the plant.

Can you elaborate on that a little bit more?

This plant may be a daffodil. Daffodils are perennial herbaceous plants with white hairs on their leaves, small bubbles on their flowers, white, pink, purple and other flowers, and they bloom from March to May and are extremely showy, making them a very popular ornamental plant. The flower language of daffodils is "love", and its flowers are small and colorful, symbolizing the beauty of love, and it is a very romantic flower.

Daffodils are also very easy to cultivate, they prefer a warm and moist environment, they can be cultivated indoors and outdoors, as long as they provide enough moisture and plenty of sunlight, they can make it thrive and bring people a beautiful visual enjoyment.

White hairs that resemble fish scales on flower stems are scale insects.

Scale insects are insects of the order Homoptera, the family Shield Scale, the female is wingless, and the feet and antennae are degenerated; The male has a pair of soft wings, well-developed feet and antennae, and stinging and sucking mouthparts. Most insects have wax paper secretions, known as shells, on their bodies. There are more than 6,000 kinds of scale insects known in the world, and there are more than 650 kinds of scale insects in 14 families recorded in China, of which more than 160 species are considered agricultural pests, which are commonly found on flower and fruit trees, often clustered on branches, leaves and fruits, and absorb plant sap for life, which will cause branch wilting or the death of the whole plant in severe cases.

There are 6 common species, including Blowing Cotton Scale, Camphor Camphor Round Shield Scale, Bran Scale, Korean Ball Scale, Mulberry White Scale, and Kang's Mealybug.

It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times. Spray once every 7-10 days, 2-3 times in a row.

Probably a scale worm.

Scale insects have wax glands and can therefore secrete waxy shells, and females have no eyes, no feet, and no antennae. Males have well-developed feet, antennae and wings, and are parthenogenetic or hermaphroditic, and some species are important pests. It usually sucks sap on the leaves or stems of plants, and in severe cases, it can cause the branches to wither or the whole plant to die.

It is a blown cotton scale insect. Scale insects tend to be winged males who can fly, but their ability to fly and crawl is weak. Once the females and larvae emerge, they live on the branches, leaves or fruits for life, causing the leaves to turn yellow, the branches to wither, and the tree to decline.

They generally like to live in damp and uncirculated places or where direct sunlight cannot be reached, and are mostly parasitic on the leaves and branches of various trees, usually hiding in plant crevices or overlapping places (such as leaf backs, under leaves, and even hiding in plant roots), parasitic on the calyx junction near the pedicle of the fruit or the depression of the fruit surface, and live by sucking the sap of plants.

Usually there is little activity on the plant, or even completely fixed on the plant. They can crawl in a small area, but the crawling distance is limited, so scale insects generally only move in different parts of the plant or in close proximity to the plant.

The leaves of the plant have white hairs, like cotton wool, which are blown cotton scale insects;

Blowing cotton scale insects, a very nasty pest, live by sucking the juice of plants, is a homoptera insect, and knows, aphids of the same order. The white cotton wool contains wax, which it secretes to protect itself from rainwater. The excrement of the scale insect contains a lot of sugar, which is often sprayed on the leaves, causing mold growth.

When the larvae of the scale insect develop, it will secrete waxy substances like white cotton wool, which is more common in April and July, and spreads rapidly, which will hinder the photosynthesis of plants and cause leaf wilting.

This should be a pest or disease.

Such as the wax mealybug, belonging to the order Homoptera, mealybug family.

This is a gall ** caused by sucking pests.

It can be sprayed with propiconazole tebuconazole 1000 times diluted.
