Why does your Onion Takmark F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The larvae of these flies live in the moist organic matter surrounding onion roots, where they feed on decaying matter and can damage fine root hairs of the Takmar hybrid. The adults emerge to lay eggs in the top layer of soil, often attracted by the high moisture levels required for onion cultivation.
While primarily known for larvae, certain fly species target the succulent tissues of Allium species. If the 'tiny black flies' are hovering near the leaves rather than the soil, they may be looking for oviposition sites on the tender onion foliage.
Though much smaller and often more slender than flies, thrips can be mistaken for tiny black insects. They feed on the onion epidermis, causing silvery scarring and potentially transmitting viruses to the Takmar hybrid.
