Methods for controlling scale insects on flowers
I. Odor-Promoting Vegetables (Scallions, Garlic, Leeks, Ginger, Onions, etc.) These vegetables each have their own distinctive odor, which can have insecticidal and bactericidal effects. Control methods: 1. Take 25 grams of garlic, crush it, squeeze out the juice, dilute it in 10 liters of water, and immediately spray the orchid plants. This can treat aphids, spider mites, scale insects, and gray mold. Alternatively, crush peeled garlic into small pieces and place them at equal intervals on the surface of the orchid pots. After a few days, earthworms and ants will disappear. 2. Soak chopped scallions in water at a ratio of 1:30 for 24 hours, filter, and spray the orchid plants several times a day for several days. This is effective in controlling aphids, soft-bodied pests, and powdery mildew. 3. Crush 1 pound of ginger with half a pound of water to extract the juice. Add 6 pounds of water to every pound of juice and spray the orchid plants. This can control aphids. 4. Mix leek juice and water in a 1:60 ratio, spray the orchid plant with this mixture twice a day for several days to cure black spot disease. 5. Take 15 grams of chopped onion bulbs, soak them in 2 jin (approximately 1 kg) of water for 7 hours, filter, and spray the orchid plant with the filtrate to treat spider mites and aphids.
II . Cigarette butts and tobacco leaves contain about 3% nicotine. Nicotine has a strong contact and stomach poison effect on pests. Take about 20 cigarette butts and one part quicklime, add water, stir, soak, filter, then add 30 parts water, and spray the orchid plant, potting soil, and bottom of the pot to kill ants and other pests without waxy coating.
III. Laundry detergent. Laundry detergent can dissolve the cornea of scale insects and form a layer of foam that envelops the insect, causing it to suffocate. Laundry detergent solution can prevent and control some pests and diseases. Prevention and control methods: 1. 1. Dissolve a small amount of laundry detergent in warm water, then dilute it to a 1000-fold dilution and spray the orchid plant to kill aphids, whiteflies, and spider mites. Dilute it to a 600-fold dilution and spray once every three days for three consecutive days to kill all scale insects. 2. Mix pig bile and water in a 1:100 ratio, add a small amount of laundry detergent, and spray the orchid plant with this solution to prevent anthracnose and soft rot. After spraying the orchid plant with the laundry detergent solution and the pests have died, rinse the leaves several times with clean water to allow the orchid plant to grow normally.
3. Mix white wine and water in a 1:2 ratio and spray the orchid plant once a week for three consecutive weeks to kill scale insects.
4. Place citrus peels at the bottom of the pot to prevent ants and other pests from entering the potting soil and harming the orchid. You can also chop citrus peels into small pieces and sprinkle them on the surface of the potting soil. After a few days without watering, this can treat aphids and scale insects.
VI. Brown Sugar: Mix powdered brown sugar and boiling water in a 1:100 ratio. After cooling, spray the orchid plants with the brown sugar solution every 3 days for a total of 3 times. This is effective in preventing downy mildew, powdery mildew, black spot, and leaf blight.
VII. Diesel Oil: Mix diesel oil and water in a 1:60 ratio to form an emulsion. Then dilute this emulsion with 100 times the amount of water and spray it on the orchid plants.
This can treat scale insects. VIII. Wood Ash: Soak wood ash and water in a 1:50 ratio for two days and nights, then filter. Spray the orchid plants with the filtrate. This can treat aphids and increase potassium fertilizer.
IX. Vinegar: Mix vinegar and water in a 1:8 ratio. Spray the mixture evenly on both sides of the orchid leaves to treat scale insects. If the scale insects are already adults, slightly increase the acidity of the mixture and spray every three days for a total of 3 times to kill the adult scale insects. Spraying foliar vegetables with vinegar solution can also eliminate black spot, powdery mildew, leaf spot, and chlorosis. Industrial grade vinegar should not be used.
