Core content of this article: Knowledge of the flower clinic, what are the small black flies in the soil, if there are any mistakes, please correct them!
For newcomers to flower cultivation, what are the small black flies in the soil may be a relatively difficult question. Academically, the scientific name of the small black fly is Sciaridae, and they are not only common near flowerpots, but also very common in damp, decomposed organic matter in the suburbs or countryside.
After knowing what the small black flies are, flower enthusiasts may want to know how to kill them. I won't mention some obscure methods, but mainly talk about relatively effective practical methods.
1) Physical extermination: The reason why there are small black flies in flowerpots is that the soil contains decomposed organic matter, such as nutrient soil, which is prone to breeding small black flies. Flower enthusiasts can cover the potting soil with a layer of material, and the author has used sand with good results; another method is to buy sticky insect boards and hang them near the potted plants, which also works well.
2) Chemical extermination: Mix furadan into the soil when mixing; for already potted plants, sprinkle furadan on the soil surface, and when sowing, you must sprinkle some furadan, otherwise, once the seedlings emerge, 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 the small black fly and root mealybug. After being absorbed by the plant, it can also prevent: mealybugs, caterpillars, aphids, mites, red spiders, thrips, caterpillars, leaf miners, flying虱, and others. After absorption, these insects will die after eating a few bites of 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, they have developed resistance……
Actually, the main reason why small black flies are泛滥 is that the medium was not completely disinfected before use. More particular flower enthusiasts should consider disinfecting and exterminating pests before using organic media in the future.
The above is [] an introduction to methods about what the small black flies in the soil are, for everyone's reference.
