Smart Use of Vegetables for the Prevention and Control of Flower Diseases and Pests
An article that provides a detailed introduction to the knowledge of flower clinics, focusing on the smart use of vegetables for the prevention and control of flower diseases and pests. The specific content is as follows:
Common pests affecting houseplants include aphids, red spiders, borers, caterpillars, ladybugs, and scale insects. These pests can cause rot, powdery mildew, soot mold, and rust diseases in flowers and plants, thus affecting their ornamental value. Flower cultivation at home, usually in rooms or on balconies, is limited in space with poor ventilation. The use or storage of highly toxic chemical pesticides is too polluting and unsafe. Given these circumstances, the author has summarized others' experiences and, through practice, believes that using vegetables commonly found in households to make pesticides for flowers is convenient, easy to use, and very effective.
Scallion: When a large bundle of scallions can be bought for one yuan in the market, it is also the season when aphids cause significant damage to flowers. Take 4 kilograms of scallions, mash them, add 25 kilograms of water, stir well, and filter to obtain 25 kilograms of juice. This can be used for gardens over 200 square meters or 100 to 150 potted flowers to eliminate aphids and also prevent rust diseases.
Onion: When eating large onions, take the parts that are not edible, such as the outer skin and decaying leaves (not dry ones), mash 2 kilograms into a paste, add 15 kilograms of water, filter, and spray. This can be used for 60 potted flowers or 100 square meters of flower fields to control aphids, soft-bodied pests, and prevent the spread of powdery mildew.
Ginger: Mash and juice, store in a small bottle, dilute with 20 times water when using, spray 150g per pot of flowers or 1 to 2 square meters of flower beds, which can inhibit the germination of rot, soot mold, and other pathogen spores.
Leek: When frying leeks, collect the outer skin layers, tips, and leaves that are discarded, chop them into a paste, extract the juice, and store it in a bottle. Dilute with half water when using and spray, which can eliminate the most persistent red spiders. Spray every 3 to 5 days, and continue for three times to completely eradicate red spiders.
Chili Pepper: Both green and red chilies can be used. When cooking, do not discard the leftover chili seeds. Mix them with half lime powder, grind into a fine powder, and spray, or mash the chili seeds, add 10 times water, and spray. About 100 grams per pot can prevent aphids and stink bugs. If mixed with half cinnamon and one-fifth nitrate of potash and ground into powder, it can be made into a fumigant that can kill small leaf caterpillars and indoor mosquitoes and flies.
Sichuan Pepper: Boil with 3 times water to make a concentrate, dilute with 10 times water when applying to make a sprayable solution. Each kilogram of the solution can be used for 6 to 10 potted flowers or 2 to 3 square meters of flower beds, controlling borers, whiteflies, and scale insects.
