Alcohol kills scale insects on succulent plants, and it kills bacteria to keep pests away.

Recently, the weather has warmed up, and the scale insects on succulent plants are ready to move again. For those who do not want to use medicine, alcohol can come in handy again. You can use syringes to extract 75% alcohol, and use syringes to spray where there are scale insects. The advantage is that they are sprayed accurately, and generally scale insects will hang when they are sprayed. Alcohol can also absorb the water of bacterial protein and make it dehydrated, denatured and solidified, so as to achieve the purpose of killing bacteria.

What are scale insects? Scale insects are insects, of course, so it doesn't matter. The important thing is that the insects of scale insects are wrapped in a layer of horniness, so it is not easy to be sprayed with drugs directly, but scale insects will absorb plant sap, so they will cause great harm to flowers and trees. In general, plants favored by scale insects will grow poorly, yellowing leaves, early defoliation and other phenomena, and when serious, it will lead to the whole plant withering.

The germicidal efficacy of alcohol is far less effective than killing scale insects. Some branches, transplants, wounds and roots can usually survive well without disinfection, and disinfection with alcohol may have more psychological effects. The principle of alcohol sterilization is to denature proteins. The shell of bacteria is peptidoglycan (similar to proteins, but there is no spatial structure), while the shell of fungi is chitin, and alcohol has little killing effect on it.

Because alcohol is volatile, there will be no residue, and there is almost no harm to the powder on succulent leaves (thin powder can be sprayed, thick powder can be sprayed carefully, it may not be easy to dry due to excessive spraying, don't try things like snow lotus, usually there is no need to kill insects, spray everything to drop powder). The use of high concentration alcohol is not recommended. If high concentration alcohol is used, the bacterial protein is dehydrated too quickly, so that the bacterial surface protein is denatured and solidified at first, forming a strong envelope, but alcohol can not infiltrate well into the bacteria. So as to affect its germicidal ability.

Alcohol is both insecticidal and bactericidal, so it has a better control effect on succulent insects and fungus diseases in the early and middle stages. Do not use in the case of direct sunlight, it is recommended not to root, I have not tried this, because it can not be volatilized directly, it may burn roots, if the plant disease is serious, it is recommended to pull out.

Spray the wound after succulent black rot, and you can also spray it after root washing, sunburn prevention, succulent beheading, and mildew of the wound can be sprayed. This spray is to dry, spray point, and then dry. Don't use small leaves and small rods, they will basically hurt the plants. Such as succulent plant Buddha bead, Ji Xing beauty and other basin protection grass. Some flower friends say not to spray the wound, it will melt, but I don't have it. I cut my head and spray it and then dry it.
