Can urea plus laundry detergent control aphids? Is this true?Spraying urea plus laundry detergent can control aphids, because urea has the effect of destroying the chitin of the aphid body wall, and laundry detergent contains the surfactant sodium alkylbenzene sulfonate, which can dissolve the waxy layer of the aphid body wall and attach to it to form a water-impermeable, air-impermeable film, causing the aphid's spiracles to become blocked and the aphid to suffocate to death. Used in combination, the two have the advantages of high efficiency, no pollution, convenience and a top-dressing effect. The method can refer to the following approach:
The mixing ratio of laundry detergent, urea and water is 1:3:300. When mixing, dissolve the laundry detergent in hot water, then add the urea and water, and stir thoroughly until evenly mixed.
Note: Stir thoroughly when mixing, and do not leave granules, as these granules can easily cause leaf burn. Spray evenly, and be sure to spray the solution onto the aphids, otherwise it will not work.
