Non-pollution vegetable pest control technology
Due to the high residual pesticides in traditional control methods, it does not meet the requirements of green vegetables. Now introduce several comprehensive prevention and control of new technologies: 1, the natural enemy pests use the licorice wasp control white powder wind, the use of Trichogramma beetle control fruitworm, corn borer, cotton bollworm. The use of seven-spot ladybugs and grasshoppers to control aphids and mites and the use of frogs to control butterflies and moth pests. 2, plant pest control can use garlic, onion, loofah leaves, tomato leaves, leaching solution made of pesticides, control of aphids, spider mites; the use of Sophora flavescens, Skunk, onion leaves leachate control aphids, cabbage caterpillars, vegetable aphids. 3. High-tech uses the virus-free technology of garlic, strawberries, and potatoes to effectively reduce the incidence of viral diseases. The use of grafting technology of vegetables, such as watermelon, eggplant, cucumber, tomato grafting, effectively prevent the occurrence of soil-borne diseases. 4. Manually kill and kill the insects using pseudo-dead and phototaxis, and kill them with black light. Tendency potato ladybugs harm eggplants and plant potato traps around eggplants. The underground pests gather under the leaves of sycamore and can trap and kill sycamore leaves. 5. Biopesticides Bio-pesticides include Bacillus thuringiensis (BT) and Pieris granulosus virus preparations. BT bio-pesticides use 150-200 ml/mu and spray once every 7 days, effectively killing 1-2 instar larvae of cabbage caterpillar, diamondback moth and soybean meal. Each mu of antibiotics with antibiotics 120 and Wuyimycin 500 ml spray, with avermectin 2500 ~ 3000 times liquid control of spider mites, aphids. Use agricultural streptomycin 4000-5000 times to control bacterial diseases of vegetables.
