What are the simple methods of eliminating diseases and insect pests in orchid culture?

What are the simple methods of orchid breeding in addition to pests? Please give me an introduction Orchids have many diseases and insect pests. For example, orchids raised at home are not convenient to use pesticides for prevention and control. The following is a special summary of how to prevent and control diseases and insect pests in orchids at home for reference: Common diseases of orchid include virus disease, white silk disease and leaf spot disease, which can be prevented by improving cultivation conditions and strengthening daily maintenance. At the beginning of the disease, the virus was sprayed with aspirin 1000 times solution; Chloramphenicol injection 1 to 1 kg of water, drenching diseased plants, 1 time a day, continuous watering 2 times; Leaf spot disease with penicillin 2000 times spray, 2 days 1 time, continuous spray 3-4 times, can have a better effect. Orchids are the main pests scale insects, aphids, red spiders. Scale insects on the orchid plant less, with toothpicks or toothbrushes one by one in addition to the large amount of malathion 500-700 times spray kill. Aphids sprayed with 10% aphidijing wettable powder 500 times, the effect is very good. 1. Simple pest control methods for orchids: 1, aphids: with 5 grams of washing powder, 1.2 kilograms of water, fully stirred after spraying, spray once every 3 days, for 2-3 times, the insecticidal rate can reach 100%. 2. Snail: Pour beer into a shallow dish and put it on the ground and basin soil. Snail will smell its fragrance and climb into the dish to drown itself. 3. Ants: After smashing garlic petals, dig 3-4 holes in the flowerpot and bury them in the pot soil. After 2-3 days, ants, earthworms and nematodes in the pot soil will disappear. 4. Red spider: After ignited with mosquito-repellent incense containing pyrethrum, put it in the orchid basin, and then seal it with plastic sleeve and basin, smoke for 1 hour, which can kill red spider eggs and adults. 5. Scale insects: soak 500 grams of mature neem fruit in 1 kilogram of water for more than 1 month, and take juice for later use. In late spring and early summer with 1:1000 times solution prevention; if found small scale insects, namely with 1:500 times solution to kill, 5 days once, three times in succession, can kill small scale insects. 2. Simple insect control methods for orchids: 1. Tobacco. Nicotine and nicotine in cigarettes can control aphids, red spiders, bugs, ants and other pests. Production: 40 grams of tobacco leaves or stems, add 1 kg of water, soak for 24 hours, filter and then add the same amount of water to dilute, add 2-3 grams of washing powder to dissolve (if the tobacco concentration can be higher; add washing powder is conducive to adhesion, but also has insecticidal effect). If you do not have a weighing device, you can soak several paperless cigarette butts in about 30 times the water, wait for the water to turn brown, and then add a little detergent to dissolve. filtering the medicinal liquid and using. Front and back of spray blade. When the pest is serious, the damaged part of the flower is immersed in tobacco water for 1-3 hours, and the plant material is soaked at the same time, which can effectively kill the pests on the leaves and in the soil. The rest of the smoke can be poured into the ant nest or sprinkled around the basin to kill ants. Buried unsoaked cigarette butts can prevent small flying insects. Notes: ① Contains nicotine, should not add vinegar, otherwise it will weaken the insecticidal strength. ② If washing powder is added, wash it with clean water the next day after spraying (or immediately after soaking). If it is mainly used for the control of scale insects, it is best to add washing powder, or use washing powder alone. 2. Garlic. Can control aphids, red spiders, scale insects, nematodes and other pests, but also control powdery mildew. Production: Take a few petals of purple garlic produced in the north, peel it and mash it, dilute it with 10-20 times water, and filter out the residue after 24 hours. Spraying the leaves with the prepared juice; pouring the residue and residual juice into the basin can control nematodes and scale insects. Note: Garlic juice has a certain viscosity, in order to prevent dust accumulation, you can wash the leaves after a few days. 3. Leek. Can control aphids, red spiders and other pests, aphids more effective. Production and use: 500 grams of leek mashed, added 1.25 kg of water, soaked for one day and night after filtering, take supernatant every other day for 3 consecutive spraying. 4. Onions. Can control aphids, red spiders and other pests, aphids more effective. Production and use: 20g onion scales immersed in 1kg water, soaked for 24 hours can be used, 1 week continuous spraying 2-3 times. In order to fully precipitate the active ingredients, it can be chopped or mashed and soaked. It needs to be filtered before use. 5. Sharp pepper (dried red pepper). Can control aphids, red spiders, whiteflies, bugs and other pests. Production and use: ① fully dry the pointed pepper, grind it into fine powder, add 50 grams of chili flour into 1 kilogram of water, boil for 10 minutes, cool and filter.② Take proper amount of dried chili, add 20 times water and boil for 20 minutes, cool and filter.③ Boil 250g dried chili seeds in 2.5kg water for 30 minutes, cool and filter. Spray wet leaves and powder, coarse powder can be sprinkled on the basin surface in small quantities; spray leaves and spray basin soil. 6. Plant ash. It can control aphids. Preparation and use: 1 part plant ash soaked in 5 parts water for 24 hours, filtered and sprayed. Use the above methods to prevent, generally once a month. It is best to alternate.
