Washing powder can still be used like this

Nowadays, every household has washing powder, but washing powder has always been used to wash clothes, but do you know that it can also be used to kill insects? Does it sound a bit ridiculous, but it is true, and interested farmer friends may wish to try it. Let's let the washing powder processing introduce how washing powder can be used in agriculture to kill insects! Let’s talk about the principle first! First, the sodium alkyl benzene sulfonate in the washing powder has a function, which can enter the insect body through the respiratory tract and cause the death of the pest; Second, the washing powder solution is moist and spreadable, and after contact with the insect body, it will quickly appear on its surface. A layer of airtight film is formed to suffocate the insects to death. To put it simply, the insects can be suffocated to death. The third is that the washing powder solution is sticky, and the adult insects will be sticky after contact and cannot take off, and will die naturally after a long time. Is this trick like sticking mouse glue, don't try to run if it sticks, starve you to death, or starve to death, this bug is so miserable, it will starve to death. How to use it? Let's talk about it in detail below. Application technology: 1. Single application: when aphids, whiteflies, red spiders, cabbage worms, inchworms, worms and other pests, use washing powder 900-1000 times to spray the back of leaves and twigs, about 11-2 hours, death The rate is 99.9: Scale insects, green peach aphid and other pests, spray 500-700 times of liquid, spray once every 3 days, spray 3 times in a row, the insecticidal rate can reach 94%-99.4%. It is clear that it can not cure all kinds of insects, farmers and friends should see the specific objects when using it! 2. Mixing with urea: The liquid prepared by this method is commonly known as 'washing urine mixture', which not only has good insecticidal effect, but also can play the role of top dressing outside the root. The preparation method is: use 0.5 kg of washing powder, 2 kg of urea, and 200 kg of water, and dissolve it after mixing; when using, generally spray 50-100 kg per mu. This method is mostly used for aphids, cabbage worms, red spiders, etc. on cotton, vegetables and flowers; because urea has the effect of destroying insect chitin, it is better than washing powder alone. After reading it, are you impressed by the washing powder again? What is the effect, farmers friends can test it! Remember, don't forget to show the effect to everyone, so that more people can see it!
