What are the small black flies in the soil
For many girls, the experience related to the flower clinic, what are the small black flies in the soil, the following editor will give you a detailed answer
For newcomers to raising flowers, what the small black flies in the soil are might be a relatively difficult question. Academically, the scientific name of the small black fly is Sciaridae. They are actually not only common around potted plants but also in damp and decaying organic matter in the suburbs or rural areas.
After knowing what the small black flies are, flower friends might want to know how to kill them. I won't mention some obscure methods, but mainly talk about relatively effective and practical ones.
1) Physical extermination: The reason why there are small black flies in the flowerpots is that the soil contains decomposed organic matter, such as nutritious soil, which is prone to breeding small black flies. Flower friends can cover the potting soil surface, and the author has used sand, which works well; another method is to buy sticky insect boards and hang them near the potted plants, which is also effective.
2) Chemical extermination: Mix furadan into the soil when preparing it; for already potted plants, sprinkle furadan on the soil surface, and when sowing, you must sprinkle some furadan, otherwise, once the seedlings sprout, they are easily eaten by the larvae of the small black fly. After sprinkling, spray water to dissolve it, and after being absorbed by the soil and plants for a few days, it can directly kill the larvae of small black flies and root mealybugs. After being absorbed into the plant, it can also prevent: mealybugs, caterpillars, aphids, mites, red spiders, thrips, caterpillars, leaf miners, flying虱, etc. After absorption, these insects will die after eating a few bites of the leaves. (Don't ask me if it's toxic, it is! But furadan does not volatilize, as long as you don't eat it directly or chew on succulents, you are safe.) PS: Earthworm丹, chlorpyrifos granules have become less effective in killing small black flies due to resistance...
In fact, the main reason why small black flies are泛滥 is that the medium has not been completely insecticidal before use. More fastidious flower friends should consider disinfecting and insecticidal treatment first when using organic medium in the future.
The above sharing of the specific introduction of what the small black flies in the soil are, I hope you will like it!
