Many people are prone to diseases and insect pests when growing vegetables due to improper management, but many people do not want to use pesticides for prevention and control. Here is a recipe for homemade vegetable insecticide . 1. Pepper water Sichuan pepper has a certain insect repellent effect, and can also be used to prevent and control insect pests on vegetables. Add 100 grams of peppercorns and 1 pound of water, put it in a pot and boil it. Then filter out the juice and add 5 pounds of water. Spray it evenly to prevent and control aphids, whiteflies , scale insects, etc. 2. Onion water Onion water has a strong pungent taste and can prevent and control a variety of pests.

It can prevent and control pests such as aphids, leaf miners, and red spiders. 3. Pepper water Look for hot peppers that are strong in flavor; the hotter the better. Use 100 grams of chili pepper, chop it into small pieces, the smaller the better, add 2 kilograms of water, put it in a pot and boil it, let it soak for a while, wait until it is completely cool, filter it, and then dilute it with 3-5 times the water and spray it to prevent and control red spider mites, aphids, leaf heartworms, etc. 4.
