In the process of growing mallow flowers, the last thing we want to encounter is problems like pests and diseases. Such problems are extremely harmful to it, and if not dealt with in time, they can easily cause the plant to wither. So what should be done when mallow flowers get bugs? And how should pest and disease control for mallow flowers be done? Below, the editor takes everyone through it.
1. What to do when mallow flowers get bugs, find the cause
To know what to do when mallow flowers get bugs, we first need to know what kind of bug it is, so that we can deal with it in a targeted way, because the control methods for each pest and disease are different. The specific control methods are introduced in detail below. Let us take a look.
2. Pest and disease control for mallow flowers (pests)
1. Aphids
Aphids are a major pest that appears on many plants, and mallow flowers are no exception. They mainly threaten mallow flower seedlings, gradually sucking the sap from the seedlings, causing the seedlings to be unable to grow and to wither and die. This shows that among the pests and diseases of mallow flowers, the harm from aphids is still very great.
Control method: The peak period for aphids is when summer begins each year, and everyone must pay extra attention at this time. When dealing with this pest, we can directly use a 1500-2000 times dilution of 40% imidacloprid water-soluble concentrate for spraying and killing.
2. Scale insects
Scale insects often appear in humid environments, so when growing mallow flowers, ventilation must be maintained. This pest mainly feeds on the leaves of mallow flowers, gradually sucking the sap from the leaves, causing the leaves to turn yellow and wither.
Control method: When dealing with scale insects, a pest and disease of mallow flowers, we can use a 2000 times dilution of 10% omethoate for spraying and killing. Generally, spraying three times in succession can completely kill this pest.
3. Pest and disease control for mallow flowers (diseases)
1. Sooty mold
Sooty mold, also called sooty blotch, is a disease that exists on many flowering plants, and mallow flowers are no exception. When the disease occurs, many small black mold spots appear on the leaves and branch tips of the plant, gradually spreading over time, and finally causing the plant to gradually wither and die.
Control method: When controlling this pest and disease of mallow flowers, we can use a 1000-1500 times dilution of 50% tebuconazole? No, 50% thiram? The source says 50% Tuzet, which is 50% Tuzet, to spray the diseased plant. Generally, spraying once every 5-7 days, and after 2-3 times it can be cured.
2. Leaf spot disease
Leaf spot disease is a disease caused by fungi, and its peak period is every summer, so everyone must pay extra attention in this season. This disease mainly threatens the leaves of mallow flowers. When the disease occurs, many round lesions appear on the leaves, and over time the lesions gradually expand, finally causing the leaves to gradually fall off.
Control method: When dealing with this pest and disease of mallow flowers, we can use a 1000 times dilution of 20% silylazole · prochloraz to spray the diseased plant. Generally, once every 10-15 days, and after 1-2 times it can be cured.

Chinese parasol tree growing methods and precautions Chinese parasol tree introduction
Chinese parasol tree, "Chinese parasol," is a plant of the genus Firmiana in the family Sterculiaceae. Its English name is Phoenix Tree, and its aliases are Qingtong and Tongma. It is also a large deciduous tree, up to 15 m tall; the trunk is straight, and the bark is green and smooth. Native to China, it is cultivated in all provinces north and south, and is also a common street tree and ornamental tree for courtyard landscaping. What we call the French plane tree is actually one kind of sycamore, only because its leaves resemble those of the Chinese parasol tree, people mistakenly think it is the Chinese parasol tree. The Chinese parasol tree grows fast, its wood is suitable for making musical instruments, its bark can be used for papermaking and ropes, and its seeds can be eaten or pressed for oil. Because its trunk is smooth and its leaves are large and beautiful, it is a famous ornamental tree species. In ancient Chinese legend, the phoenix "does not perch except on the Chinese parasol tree." Many legendary guqins were made from Chinese parasol wood, and the Chinese parasol tree played an important role in Chinese culture. The writer Feng Zikai's essay of the same name, "Chinese Parasol Tree," can be called a fine piece. The Chinese parasol tree has already been introduced to many countries in Europe, the Americas and elsewhere as an ornamental tree species.
Morphological characteristics and appearance of the Chinese parasol tree
The Chinese parasol tree is a deciduous tree, up to 15 m tall; the leaves are green and smooth.
Leaves
The leaves of the Chinese parasol tree are heart-shaped, palmately 3-5 lobed, 15-30 cm in diameter, with triangular lobes, acuminate tips, heart-shaped bases, hairless or slightly covered with short soft hairs on both sides, 7 basal veins, and petioles as long as the leaf blades.
Flowers
The Chinese parasol tree has terminal panicles, about 20-50 cm long, with lower branches up to 14 cm long, and pale purple flowers; the calyx is deeply 5-parted almost to the base, the sepals are linear and curled outward, 7-9 mm long, covered with pale yellow short soft hairs outside and only at the base inside; the pedicel is almost as long as the flower; in male flowers, the androgynophore is as long as the calyx, thicker in the lower half, hairless, with 15 anthers irregularly clustered at the top of the androgynophore, and the rudimentary ovary is pear-shaped and very small; in female flowers, the ovary is spherical and covered with hairs.
The flowering period of the Chinese parasol tree is around June.
Fruit
The Chinese parasol tree has membranous follicles, stalked, splitting open into a leaf-like form before maturity, 6-11 cm long and 1.5-2.5 cm wide, with short down outside or nearly hairless, each follicle having 2-4 seeds; the seeds are spherical, wrinkled on the surface, about 6-7 mm in diameter.
Ecological habits of the Chinese parasol tree
The Chinese parasol tree is a light-loving plant. It likes a warm climate and is not cold-tolerant. It is suitable for growing in fertile, moist sandy loam and likes alkaline soil. The roots are fleshy and not tolerant of waterlogging; it is deep-rooted, and the roots are thick and strong; its sprouting ability is weak, and it is generally not suitable for pruning. It grows fairly fast and has a long lifespan, able to live more than a hundred years. During the growing season, 3-5 days of waterlogging will rot the roots and kill it. It leafs out relatively late and sheds its leaves early in autumn. The leaves, flowers, roots and seeds can all be used as medicine, and the seeds can also be stir-fried for food and pressed for oil. It has strong resistance to many toxic gases. It is afraid of viral diseases, afraid of the large bagworm moth, and afraid of strong winds. It is suitable for planting beside village roads, near homes, on hillsides, on limestone hillsides and other places. A sun-loving tree species, it thrives in warm, humid environments; it tolerates severe cold, drought and barren soil. In summer, the bark is not tolerant of blazing sun. It grows better on sandy soil.
Cultivation techniques for the Chinese parasol tree
The Chinese parasol tree is commonly propagated by sowing, and cuttings and root division are also possible. Harvest when the fruit ripens in autumn, dry and thresh, then sow in autumn of the same year, or store in sand until spring sowing the following year. Drill sowing with 25 cm row spacing, covering with about 1.5 cm of soil. The sowing rate is about 15 kg per mu. Seeds stored in sand germinate more uniformly, sprouting 4 to 5 weeks after sowing. Dry-stored seeds often germinate unevenly, so they can first be soaked in warm water before sowing to promote germination. Under normal management, seedlings can reach more than 50 cm in height in the same year, and are transplanted and grown the following year. Three-year-old seedlings can be sent out from the nursery. The planting site should be chosen in high, dry terrain, with base fertilizer applied in the hole, and after trunk determination, the saw cut should be sealed well with wax. Pay attention to pests such as the Chinese parasol psyllid, the frost hawkmoth and the slug moth, which can be controlled with petroleum emulsion, dichlorvos, dimethoate, methamidophos and so on. In the north, young trees must be wrapped with straw rope in winter to protect against the cold. Fertilize once each in early winter and early spring.
Disease and pest control for the Chinese parasol tree
The main diseases and pests of Qingtong are the Qingtong psyllid, the cotton leaf roller and so on.
Qingtong psyllid
The Qingtong psyllid, also called the Chinese parasol psyllid, is the main pest of Qingtong. The psyllid uses nymphs and adults to suck sap on the underside of Chinese parasol leaves or on young twigs and trunks, damaging the conductive tissues. Young trees are especially vulnerable. In severe cases, the leaves of the whole plant turn yellow and the top shoots wither. The white cottony waxy substance secreted by the nymphs clogs the leaf stomata, affecting normal leaf respiration and photosynthesis, making the leaf surface appear pale and shriveled. When the wind blows, the white waxy threads flutter in the wind like flying mist, and the flocculent material drifts down. If people accidentally touch it, it feels sticky and has a foul smell, and it is very difficult to clean. It seriously pollutes the surrounding environment and affects the city's appearance.
Control methods
Chemical control: in mid-to-late May, spray 2000-2500 times dilution of 10% aphid-leafhopper net powder, 1000 times dilution of 2.5% imidacloprid, or 2500-3000 times dilution of 1.8% abamectin.
During the damage period, spraying clear water to wash off the flocculent material can kill many nymphs and adults. In early spring, spray 8 times dilution of 65% soap petroleum emulsion to control overwintering eggs.
The boil bat moth harms Chinese parasol, magnolia and other trees. A veterinary syringe can be used to inject 400 times dilution of 40% fenitrothion emulsifiable concentrate into the tunnels at the damaged areas to poison the larvae. Petroleum emulsion, dichlorvos, dimethoate, methamidophos and so on can also be used for control.
Pay attention to protecting and using natural enemy insects such as parasitic wasps, ladybugs and lacewings.
Cotton leaf roller
The larvae of the cotton leaf roller roll leaves into a cylindrical shape and hide inside while eating the leaves into notches or holes. In severe cases, they eat all the cotton leaves and continue to damage the bracts in cotton bolls or tender buds, affecting the growth and development of the cotton plant.
In addition to damaging cotton, its hosts also include amaranth, hollyhock, Abelmoschus manihot, velvetleaf, hibiscus, kapok and so on.
Control methods
Use your hands to crush the larvae and pupae inside the rolled leaves.
During the larval occurrence period, spray 1500 times dilution of 40% dimethoate emulsifiable concentrate, or 2000-3000 times dilution of 5% imidacloprid emulsifiable concentrate, or 3000-4000 times dilution of 25% chlorbenzuron No. 3, once every 7-10 days.
Variety classification of the Chinese parasol tree
1. American sycamore (Platanus occidentalis)
2. London plane (Platanus acerifolia)
3. Oriental plane (Platanus orientalis)
They belong to Rosales and so on, and are not recommended to be placed under Chinese parasol tree.
Distribution range of the Chinese parasol tree
The Chinese parasol tree is mainly produced in Zhejiang, Fujian, Jiangsu, Anhui, Jiangxi, Guangdong, Nanjing, Hubei and other provinces and regions, and is distributed from Hainan Island in Guangdong to Shandong, Beijing and Hebei in North China. It is also distributed in Japan, Korea and South Korea. It is mostly artificially cultivated.
The Chinese parasol tree is also more common in the Yangtze and Pearl River basins.
Landscape uses of the Chinese parasol tree, horticultural landscape
The Chinese parasol tree has a tall and sturdy trunk, luxuriant branches and leaves, an oval crown, a straight trunk, and smooth green bark, with sturdy side branches in emerald green. It grows rapidly, is easy to establish, and tolerates pruning, so it is widely planted as a street greening tree species and is also a fast-growing timber tree species; it has strong resistance to toxic gases such as sulfur dioxide and chlorine. The leaves, flowers, roots and seeds can all be used as medicine. It is often used for garden viewing, in communities, gardens, schools, institutions, factories, hillsides, courtyards, roadsides and in front of buildings.
Uses and purposes of the Chinese parasol tree, Chinese parasol seeds
Chinese parasol seeds are the dried mature seeds of the plant Chinese parasol of the family Sterculiaceae. They are harvested from late autumn to early winter, impurities removed, and sun-dried. The dried seeds are spherical or nearly round, 6-8 mm in diameter, yellow-brown to dark brown, with the surface shrunken into a net-like pattern. The outer seed coat is relatively brittle and easy to break, while the inner seed coat is tough. After removal, inside there is thick pale yellow endosperm; the two cotyledons are thin and large, pressed closely against the endosperm, and the radicle is located at the narrower end. Both odor and taste are slight. Those that are large, plump, brown and free of impurities are considered best. Tao Yinju said: "There are four kinds of tong trees. The Qingtong has green leaves and bark like the wutong but no seeds. The wutong is white in color, its leaves resemble those of Qingtong and it has seeds, and the seeds are plump and can also be eaten." Li Shizhen said: "The wutong is found everywhere. The tree resembles the tong but its bark is green and not cracked, its wood has no knots and grows straight, and its grain is fine and its nature is tight. Its leaves resemble those of the tong but are slightly smaller, smooth and pointed. Its flowers have fine stamens, which fall down like mold. Its pods are about three cun long, formed of five pieces, and when old they split open like a winnowing basket, called gaoe. Its seeds are attached to the gaoe, as many as five or six, or as few as two or three. The seeds are as large as peppercorns, and their coats are wrinkled. The seeds are sweet, neutral and nontoxic." Examining the wutong recorded in the Zhenghe Bencao and the Bencao Gangmu, it is the wutong of the family Sterculiaceae.
Main uses
The Chinese parasol tree is an ornamental tree cultivated in courtyards. Its wood is light and soft, a good material for making wooden boxes and musical instruments. The seeds can be eaten after being stir-fried or pressed for oil, and the oil is a non-drying oil. The root bark, stems, leaves, flowers, fruits and seeds can all be used medicinally, treating diarrhea, hernia and premature graying of beard and hair, and having the effect of clearing heat and detoxifying. The fibers of the bark are white and can be used for papermaking and rope weaving and so on. Wood shavings can soak out a mucilage, called planing shavings, which is used to smooth the hair.
Cultural background of the Chinese parasol tree, ancient poems praising the wutong
Because the Chinese parasol tree is tall and upright, it is outstanding among trees. It has been valued since ancient times. Moreover, the Chinese parasol tree is often linked with the phoenix. The phoenix is the king of birds, and the phoenix most likes to perch on the Chinese parasol tree, which shows how noble the Chinese parasol tree is. In China's Classic of Poetry there are records about the Chinese parasol tree. In the Classic of Poetry, in the "Juan A" of the Major Court Hymns, a poem says:
"The phoenix sings, on that high ridge. The Chinese parasol tree grows, in that morning sun. Luxuriant and lush, harmonious and melodious."
This poem says that the luxuriant growth of the Chinese parasol tree attracted the phoenix to cry out. "Luxuriant and lush" is the abundance of the Chinese parasol tree; "harmonious and melodious" is the sound of the phoenix's cry.
In Zhuangzi's Autumn Floods chapter, the Chinese parasol tree is also mentioned. Speaking of Zhuangzi meeting Huizi, it says: "In the south there is a bird, its name is yuanchu. Do you know it? The yuanchu starts from the South Sea and flies to the North Sea, and it does not rest except on the Chinese parasol tree..."
In this chapter, the Chinese parasol tree is also linked with the phoenix. The "yuanchu" here is a kind of phoenix. He says the phoenix flew from the South Sea to the North Sea, and only when it met the Chinese parasol tree did it descend onto it. This shows the nobility of the Chinese parasol tree.
In Chapter 37 of Romance of the Three Kingdoms, there is this description: "The phoenix soars among a thousand fathoms, and does not perch except on the wutong; a scholar lies hidden in one place, and does not serve except a true lord."
Because the ancients often linked the Chinese parasol tree with the phoenix, people today often say: "Plant a Chinese parasol tree, and the phoenix will come of itself." Therefore, in formerly well-off households, Chinese parasol trees were often planted in the courtyard, not only because the Chinese parasol tree has presence, but also because the Chinese parasol tree is a symbol of good fortune.
There is even a Hakka nursery rhyme: "A child beats the tong seeds, the tong seeds fall and the child is happy."
Essay
Feng Zikai, "Chinese Parasol Tree"
In front of the window of my apartment there are several Chinese parasol trees. These are all things in the neighbor's yard, but in form they are mine. Because they are at a suitable distance from me, it is as if they were planted especially for me to look at. Their owner perhaps sees their partial states more clearly than I do; but as for their overall appearance, that requires a considerable distance to be seen. A Tang poem says, "Only from afar does a mountain begin to show its face." I think the same is true of trees. From early summer to now, these several Chinese parasol trees have shown all kinds of appearances before me, now heavily made up, now lightly touched.
When spring ends and summer begins, I saw with my own eyes the scene of the new Chinese parasol trees first budding. Those tender yellow little leaves clustered atop the bare branch tips, like a hall of tree lanterns, and also like the cut-and-paste designs of schoolchildren, arranged evenly and with a childish air. The leafing of plants also has all kinds of techniques. Some replace the old with the new, deceiving people's eyes and secretly swapping green for yellow in the dark. Some are so slight and gradual that people do not notice them changing from bare branches into green leaves. Only the Chinese parasol tree's leafing technique is the clumsiest, but its attitude is the most frank. Their branch tips are sparse and thick, and their leaves are flat and large. Once the leaves are born, the whole tree clearly changes appearance.
In summer, I again saw with my own eyes the scene of green leaves forming shade. Those round-fan-like leaves grew layer upon layer densely. Looking at them, not a thread of gap remained, like a great green screen, and also like a green mountain in a pattern painting. Among the courtyard plants I commonly see, as for the size of leaves, apart from the banana, I am afraid none surpasses the Chinese parasol tree. Although banana leaves are large in shape, their number is not great; the clove-like roll takes several days to unfold one leaf, and the leaves of the whole tree are few and countable. Although Chinese parasol leaves are not as large as those, their number is greater. Those pig's-ear-like things hang in overlapping layers, from the low branches all the way to the top of the tree. With several branches of Chinese parasol placed before the window, I feel there is really too much greenness. The ancients said, "The banana shares its green up to the window gauze," but their vision was too low, only what was seen before the steps and under the window. If one climbs the tower and looks out, the banana falls below the eye, and one should see "the Chinese parasol shares its green up to the window gauze."
For a month now, I have again seen with my own eyes the scene of Chinese parasol leaves falling. The appearance is truly miserable! At first the green darkened and became ink-green; later it turned from ink-green to scorched yellow; when the north wind rose, they made a great fuss, and the large yellow leaves began to leave the branches - at first one or two suddenly dropped off, and later a large batch flew down in groups, like something thrown down from a tall building by someone. The branch tips gradually became empty, revealing the houses behind the trees, until finally only a few branch tips remained, returning to their early-spring appearance. These days they stand empty-handed before my window, like a bachelor who once married and had children but whose family is now broken and people gone, looking quite pitiful! I recall the ancients' poem: "High on the mountain stands a tree, the wind blows its leaves away. Once gone several thousand li, when can they return to their old place?" If one were to gather all their fallen leaves and make them all turn green together, return to the old branches, and restore the summer scene, even with the power of all the rulers in the world and all the mechanical efficiency in the world, it would be impossible. In the world there are many returns from yellow to green, but none symbolizes sorrow like fallen leaves, especially the fallen leaves of the Chinese parasol tree. Falling flowers have also made people sorrowful. But the lifespan of flowers is short, like an infant dying as soon as it is born. Though we pity it, because our connection with it has not been long and our memories are few, our sorrow is therefore not deep. The lifespan of leaves is much longer than that of flowers, especially Chinese parasol leaves. From first birth to falling completely, they occupy more than half a year, and moreover they are so luxuriant, so grand! The tall, thick, dense piles of great green before the eyes, in one morning turned into nothing! There is no greater symbol of "impermanence" than this!
But their owner, I am afraid, has not felt this sorrow. Because although they planted them and owned them, they have not seen the various scenes described above. They merely sit under the window and glance at their roots and trunks, stand before the steps and look up at their branches and leaves, and sweep their fallen leaves for them. How could they see their appearance? How could they feel their symbolism? Thus it can be known that nature cannot be possessed. It can also be known that art cannot be possessed.

The world-famous street tree, the French plane tree, can often be seen in Chinese parks and along both sides of roads. Today in China it is cultivated from Dalian, Beijing and Hebei in the north, to Shaanxi and Gansu in the west, to Sichuan and Yunnan in the southwest, and to Guangdong and the eastern coastal provinces in the south. In Nanjing, ordinary people all abbreviate it as "Fatong" or "Fawu," yet it is neither the Chinese parasol tree nor native to France, and what we often call the Chinese parasol tree actually refers to the "Chinese parasol."
What people habitually call the "French plane tree" is only one kind of sycamore. Originally, the genus Platanus has 8 species, native to North America, Mexico, the Mediterranean and India. Three species have been introduced and planted in our country. As for the fruits on the fruit stalk of the sycamore, some have 1 fruit ball, some have 2 fruit balls, and some have more than 3 fruit balls, so the names differ, and they are respectively called American sycamore, London plane and oriental plane. These are three different species. Lishi Wuyu summarizes them as follows:
American sycamore (Platanus occidentalis, native to North America, commonly called "American sycamore" or "Meitong")
London plane (Platanus acerifolia, commonly called "London plane" or "Yingtong")
Oriental plane (Platanus orientalis, native to southeastern Europe and India, commonly called "French plane tree" or "Fatong")
Why is the sycamore called the "French plane tree"? Originally, this tree's leaves resemble those of the Chinese parasol tree, so everyone mistook it for the Chinese parasol tree. In the 17th century, in Oxford, England, people used the American sycamore (also called American sycamore) and the oriental plane (also called French plane tree) as parents and crossed them to produce the London plane, naming it "London plane." Because it is a hybrid, it has no place of origin. After it was widely cultivated in Europe, the French brought it to Shanghai and planted it along Avenue Joffre (today's Middle Huaihai Road area) as street trees. People called it the "French plane tree," and following one another, they treated it as the Chinese parasol tree.
I believe many children who grew up or played in Nanjing would take the fruits of the French plane tree to play with. (In 1925, to commemorate Mr. Sun Yat-sen, the Sun Yat-sen Mausoleum was planned and built, and street trees, namely French plane trees, were planted along both sides of Zhongshan Avenue and Lingyuan Road. Later, under the planning of the Nationalist Government, Nanjing once had as many as 200,000 French plane trees. The French plane tree is Nanjing's mother tree, and the French plane tree has already become part of Nanjing. First, one breaks off the hairs on the fruit and blows them; second, there is a net-like substance on the seeds, and children all take it off and call it a little fishing net. Under French plane trees in summer, one can often see "hanged ghosts," called "bagworms" or "case moths" in entomology. These insects use small twigs and leaves to spin silk into a bag to protect themselves, and they spin silk to hang down from the trees. Ordinary farming households, if they raise chickens at home, catch them and cut open the bag, take out the insect body and feed it to the chickens.)
Botanically, the French plane tree (oriental plane) belongs to the large deciduous trees, and can reach 35 m in height. The branches spread out, the crown is broad, and it is oblong-elliptical. The bark is gray-green or gray-white, falling off in flakes. Buds are beneath the leaf scar, leaves are alternate, large, palmately 5-9 lobed, densely covered with stellate soft hairs when young, later falling off. The flowering period is April-May, with spherical heads. The cones hang down, usually 2 in a string. The fruit ripens in September-October, and the base of the nut has long hairs. Deciduous tree, up to 35 m tall; branches spread out, crown broad; bark gray-green, irregularly flaking off, after falling off appearing powdery green and smooth. Leaf blades triangular, 9-15 cm long, 9-17 cm wide, 3-5 palmately divided, with irregular sharp teeth and wavy teeth along the margin, crown broad; bark gray-green, irregularly flaking off, after falling off appearing powdery green and smooth. Leaf blades triangular, 9-15 cm long, 9-17 cm wide, 3-5 palmately divided
Base truncate or nearly heart-shaped, with stellate hairs when young, later nearly hairless. Spherical inflorescences 2.5-3.5 cm in diameter, usually 2 in a string, shaped like hanging bells; flowers about 4 mm long; sepals 4; petals 4; male flowers; male flowers have 4-8 stamens; female flowers have 6 separate carpels. Flowering period May, fruit ripening period September-October.
