What are the small black flies in the soil?
Do you know these? Content about flower clinics, what are the small black flies in the soil, let's find out together below.
For newcomers to flower cultivation, what the small black flies in the soil might be can be a relatively difficult question. Academically, the scientific name of the small black fly is Sciaridae. They are not only common near potted plants but can also be found in damp, decayed organic matter in the suburbs or countryside.
After knowing what the small black flies are, flower enthusiasts might want to know how to kill them. I won't mention some unusual methods; instead, I'll focus on relatively effective practical methods.
1) Physical extermination: The reason there are small black flies in the potted soil is that the soil contains decayed organic matter, such as nutrient-rich soil, which is prone to breeding small black flies. Flower enthusiasts can cover the soil surface with sand, which has proven effective; another method is to buy sticky insect boards and hang them near the potted plants, which also works well.
2) Chemical extermination: When mixing soil, add furadan; for already potted plants, sprinkle furadan on the soil surface, and when sowing, it is necessary to sprinkle some furadan, or else once the seedlings sprout, they are easily eaten by the larvae of the small black flies. 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 by the plant, it can also prevent: mealybugs, caterpillars, aphids, mites, red spiders, thrips, caterpillars, leaf miners, plant hoppers, etc. After absorption, these insects will die after eating a few bites of the leaves. (Don't ask me if it's poisonous, 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 rampant is that the medium has not been completely disinfected before use. More particular flower enthusiasts should consider disinfecting and exterminating before using organic media in the future.
