Washing powder is a common commodity, but most people may not know that it can be linked to agricultural production. Washing powder is transformed into an insecticide, which is effective and saves money.
Washing powder can kill pests
Washing powder is a kind of contact insecticide and acaricide, which has a good control effect on pests (aphids, red spiders, whitefly, scale insects, etc.) that are prone to occur in vegetable cultivation.
Spraying 300-500 times of neutral detergent powder spray can prevent whitefly adults, nymphs and scale insects;
Spray 500-700 times liquid spray of neutral detergent to prevent scale insects, green peach aphid and other pests. Spray once every 3 days for 3 times, and the insecticidal rate can reach 94% to 99.4%;
Spraying 500-800 times liquid spray of neutral detergent powder can control adult aphids, nymphs, adult mites, nymphs and young mites, and inhibit the hatching of mite eggs;
Irrigating roots with 800-1000 times solution of neutral detergent can prevent and control nematodes in roots and tubers. In addition, washing powder also has a certain control effect on some Lepidoptera larvae and Pieris larvae;
Use 900-1000 times of neutral detergent to spray leaf backs and twigs to control aphids, whiteflies, red spiders, cabbage caterpillars, loopers, spiny moths and other pests. After about 1 to 2 hours, the mortality rate will reach 100% .
