What are the little black flies in the soil
The editor will answer your questions about the knowledge of the floral clinic, what are the little black flies in the soil, and the specific details are as follows:
For newcomers to gardening, what the little black flies in the soil might be can be a somewhat difficult question. Academically speaking, the scientific name for the little black fly is Scirtetomyia, and it is not only common near potted plants but also very common in moist, decayed organic matter in the suburbs or countryside.
Knowing what the little black fly is, flower enthusiasts may want to know how to kill it. I won't mention some unconventional methods here, just the relatively effective practical ones.
1) Physical extermination: The reason why there are little black flies in the pot is that the soil contains decayed organic matter, such as nutrient soil, which is more likely to breed little black flies. Flower enthusiasts can cover the soil surface with sand, which has worked well for the author; 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 plants that have already been potted, 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 little 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 little black fly and root mealybug. Once absorbed by the plant, it can also prevent: mealybugs, caterpillars, aphids, mites, red spiders, thrips, caterpillars, leaf miners, plant hopper, etc. 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 little black flies due to resistance...
Actually, the main reason why little black flies are泛滥 is that the medium has not been completely pest-exterminated before use. More meticulous flower enthusiasts should consider sterilizing and pest-exterminating organic media before using them in the future.
