There is no doubt that cabbage can be sprayed with vinegar. When spraying vinegar, it is best to choose white vinegar and choose sunny weather to spray, which will have the best effect. Spraying cabbage with vinegar can increase yield, achieve the goal of increasing production and income, and improve the economic benefits of vegetable farmers.

Is it true that spraying vinegar on cabbage can repel insects?

real.

The pests that cabbage is particularly prone to attract generally include aphids, leaf wasps, leaf weeds, seed flies, diamondback moths, cutworms, etc., and these pests have one thing in common, that is, they all like alkaline environments and dislike acidic environments.

Therefore, spraying vinegar on the cabbage leaves is equivalent to destroying the comfortable living environment of these pests. The acidic environment itself is corrosive, and the strong stimulation is not suitable for insects to survive, which just happens to play the role of killing and preventing insects.

What is the claim that spraying vinegar on cabbage can increase yield?

Using edible vinegar to spray during the cabbage planting process can indeed increase production and income. In addition, edible vinegar has been widely used in vegetable planting in agricultural planting in recent years. However, it should be noted that you must use edible vinegar, that is, rice vinegar.

Because edible vinegar contains a lot of acetic acid, amino acids, glycerol and other substances, spraying them on cabbage leaves can promote the photosynthesis of cabbage and improve its nutrient absorption capacity, thereby stimulating better growth and development of cabbage. Generally speaking, during the planting process of cabbage, white vinegar should be diluted 300 to 400 times and sprayed. It is best to do it 2 to 3 times during the entire growth period.

Scientific research shows that spraying white vinegar during cabbage planting can effectively increase cabbage yields by about 10% to 15%. Moreover, edible vinegar is an acidic substance that can prevent cabbage soft rot and certain alkaline pathogens, and has the effect of killing pests and diseases, which also increases yields to a certain extent.

Should I use white vinegar or black vinegar when spraying vinegar on cabbage?

It also has the effect of preventing diseases and pests, and the effect is very good.
