Why do cucumbers and peppers spray vinegar?
Vinegar is not only used in vegetables now, as early as many years ago someone has begun to use, vinegar has a function that everyone knows, that is, it has a bactericidal effect, and another, vinegar is acidic, but also contains some substances that can be directly absorbed by crops, such as: acetic acid, grape acid, amino acids, calcium, etc. These substances can promote the growth of crops to a certain extent, and can make crops grow better while killing bacteria. Moreover, vinegar is something that people eat, so there is no need to worry about residues and harm.
What are the benefits and effects of spraying vinegar?
1. It can sterilize, and the bactericidal effect of vinegar is well recognized, which has a certain killing effect on some fungal and bacterial diseases on the leaves, and reduces the occurrence of various diseases. But first of all, it should be clear that vinegar is not a pesticide in general, its role only plays an auxiliary role, if a disease really occurs, it is far from enough to use vinegar alone, and it also needs to be used with drugs. For example: to prevent and control cucumber downy mildew, you can use enoylmorpholine to mix it with water according to the instructions, and then add 20 grams of vinegar to 30 kg of solution.
2. It can promote growth and increase yield
Vinegar can not only kill bacteria and prevent diseases, but also increase the photosynthesis and chlorophyll of the leaves after the substances in it are absorbed by the branches and leaves, promote the growth of the plant, and increase the stress resistance and disease resistance of the plant. According to the effect of previous use, cucumber and pepper can increase the yield by more than 15%, and the quality of cucumber and pepper has also improved, and the effect will be more obvious if used in combination with other acidic foliar fertilizers. But there is one point, vinegar can only be used as a leaf spray, not for watering.

After the cucumber and pepper seedlings are set and the seedlings are slowed, you can start spraying, generally every 10 days or so, do not spray at the beginning of the flowering period, and then spray after the melon. When there is no disease, it can be sprayed with foliar fertilizer, and when the disease first appears, it can be sprayed with the corresponding fungicide. Again, like: vinegar with glucose, with potassium dihydrogen phosphate, etc., these are all good methods. But there is a point. It should be noted that vinegar can only be used with neutral or acidic fertilizers and medicines, not alkaline fertilizers and medicines.
What is the concentration of water?
Vinegar is an acidic substance, although it is said to be an edible item, but it can not be used casually, it will corrode the leaves when used alone, it must be diluted with water, generally 300-500 times with water, if it is matched with fertilizers and medicines, it needs to be mixed with water more than 500 times. There is another one, blended vinegar and acetic acid can not be used, it is best to choose good quality brewed vinegar, the one without salt is better, rice vinegar is preferred, followed by white vinegar.
