Potted flowers not only help to beautify the environment but also regulate the air. Most homes are planted with potted plants. What are the pests of potted flowers? How to prevent it? Presumably, many people are not too clear. Next, Xiaobian will summarize the pests and diseases of potted flowers and how to prevent them?
1 disease
Common diseases of indoor flowers include leaf spot and powdery mildew.
1.1 Powdery mildew
1.1.1 Characteristics of occurrence. Powdery mildew is the most common fungal disease, mainly affecting the leaves and twigs of various flowers such as rose, peony, cineraria, primrose, peony, chrysanthemum, flat bamboo carp, and inverted golden bell. When the temperature reaches 18 °C to 30 °C, if the ventilation is very easy to occur, the damaged plant first appears yellow spots on the leaves and grows a layer of white powder. When it happens seriously, the flowers are small and small, and the leaves are dry and even the whole plant is dead.
1.1.2 Control measures. 1 pay attention to ventilation, control humidity, enhance light, can prevent powdery mildew. 2 Strengthen daily management, use root irrigation when watering, and minimize leaf surface watering to reduce air humidity. 3 found diseased leaves, diseased buds and early removal and deep burial. 4 Pharmacy protection, spraying 25% powder rusting 1 000-2 000 times liquid at the beginning of the disease, or 50% carbendazim 500 times solution.
1.2 Leaf spot disease
1.2.1 Occurrence characteristics. Leaf spot disease is a common fungal disease. Including black spot, brown spot and other types, it is a variety of flower leaves such as rose, rose, peony, chrysanthemum, Clivia, etc., there are black or brown round or irregular shaped spots and wheel spots on the damaged leaves. Black mold, black dots, etc. appear in the damp, reducing the ornamental value of flowers.
1.2.2 Control measures. 1 Combine daily maintenance management to remove dead branches, fallen leaves, diseased branches, burned or buried deeply in time to reduce the source of the bacteria. 2 indoor attention to ventilation, reduce the temperature, the basin distance should not be too dense, in order to facilitate ventilation and light. 3 Pharmacy protection. Spray 200 times 0.5% equivalent Bordeaux solution or 70~, 4 methyl thiophanate 1000 times solution.
2 pests
Insect pests are mainly aphids, scale insects, spider mites, and whitefly.
2.1 Locust
2.1.1 Characteristics of occurrence. Aphids, commonly known as worms and honey worms, are harmful to a variety of flowers. They mainly accumulate in the young shoots, flower buds and leaf backs to suck the plant juice, making the leaves curl and yellow, and the plants grow slowly, affecting normal flowering. At the same time, a large amount of honeydew excreted by mites can induce coal pollution and seriously affect photosynthesis.
2.1.2 Control measures. 1 Check in time, find a small amount of mites can be brushed off with a brush to avoid brushing the young shoots, young leaves, the mites under the brush should be cleaned in time to prevent spread. 2 Take 2-3 pieces of skunk leaves and cut them, add water l0 to l5 times to boil for 1 h, and spray the filtrate with a sprayer to kill the mites. 3 Take an egg or duck egg and pour it into a bottle. Add 1-2ml of cooking oil, add 200ml of cold water, cover the bottle cap, shake up and down several times, pause for a while, and spray until the liquid surface is free of oil. It also has a certain effect on aphids and spider mites. 4 Take 20 g of dried chili, add 1 kg of water to boil, use its clear liquid to spray insects such as aphids and mites.
2.2 Leafhoppers
2.2.1 Occurrence characteristics. Ye Wei, also known as the fire dragon, is small in shape, red, and can be seen by the naked eye. It occurs most under high temperature conditions, and often gathers a large amount of leaf back to suck juice. Some have netting habits, which can harm many Chinese flowers, such as rose, peony, hollyhock, spring, camellia, geranium and so on. Yellow spots appear on the front of the damaged leaves, and the yellow leaves fall off when heavy, which is the most harmful to flower growth.
2.2.2 Control measures. 1 Increase the humidity and proper ventilation to reduce the growth of leafhoppers. 2 spray tobacco water, formula: 40 g of tobacco, add water l kg, soak for 48 h, then filter, add 1 kg of water to the stock solution, add 2-3 g of washing powder, stir and spray. 3 Take 4 g of flour, put it into a porcelain bottle, add a little water to make a paste, add 200 ml of boiling water, cool and filter and spray. 4 Take the general laundry soap and cut into thin slices, dissolve with boiling water (add water according to the ratio of 1:60-70), spray and spray to prevent leafhoppers and mites. If soaking the cigarette butts with soapy water, it can improve the control effect and cure the whitefly. , Ye Hao and so on.
2-3 whitefly
2.3.1 Occurrence characteristics. Whitefly, also known as the white moth, is a common pest in the greenhouse or in the living room. It can damage a variety of flowers, such as fuchsia, hibiscus, rose, cineraria, orchid, peony, fig and so on. It often gathers the back of the leaf, sucks the juice, especially the young leaves suffer the most serious. In severe cases, the leaves die and fall off, and the excrement of the adult often causes the occurrence of coal pollution.
2-3.2 Control measures. 1 Chop the leaves of oleander, add water and boil for half an hour, filter to kill whitefly and aphids, scales. 2 Take a small wooden stick, bundle a small cotton ball with a dichlorvos solution at one end, and insert the other end into the pot of the affected plant. The whitefly, aphids and other pests will be killed soon. If the pest is serious, use one more. The plastic bag is put on the flower pot, and the insect will be smoked after 4-5 h. 3 Dilute the washing powder by 400 times with water, spray on the insect body, spray once every 5 to 6 days, and even spray 2-3 times to kill the whitefly, eggs and nymphs. At the same time, it can also control aphids and scale insects. Soap water and washing powder water should not be used for a long time, otherwise it is easy to cause alkaline to potted soil, which is not conducive to flower growth.
2.4 snails
2.4.1 Occurrence characteristics. Commonly known as tree scorpion, a wide variety, a variety of flowers, such as figs, rose, peony, thorn rose, hydrangea, camellia, mulberry, etc., the plant grows slowly, the leaves are yellow, and the large amount of honeydew released by the scale insects can be induced The occurrence of coal pollution.
2.4.2 Control measures. 1 timely inspection, early prevention, when the amount of insects is small, you can use a brush or bamboo to manually brush or cut off the damaged branches and leaves, burned intensively. 2 Take 1 part of the cigarette butts and soot in the ashtray, add 40-50 parts of water, soak for l day and night, spray and spray after spraying, which has certain effect on the newly hatched scale insect. 3 can refer to the control measures of whitefly.
Disperse dye Printing Thickener as the main additive in the chemical printing industry, because of its excellent thickening, has already appeared in people's field of vision early, its true face is a rheological additive, can be no exaggeration It is said that it only needs to add a small amount of thickener to make it play a big role. Is its advantage only reflected in this amount? No, let me introduce you to the specific advantages of disperse dye printing thickeners.
1. After the consistency of the raw liquid product is increased, the raw liquid is better penetrated into the textile and uniformly sizing.
2. Provide good rheological properties for dyes or pigments, so that they are evenly distributed during printing without splashing and sagging.
3. Better penetration of the dye into the textile, combined with the fibers to form a well-defined, well-defined textile print.
4. The consistency is increased, so that the dye in the printing is fixed, and the reaction product and the residue are more conveniently and easily washed away.
Disperse dye printing thickeners are widely used in the thickening of textile printing and dyeing, coatings, printing and dyeing, sanding cloth, cotton cloth, chemical fiber cloth and other systems.
