Why does your Turnip Tokyo Cross F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe larvae of these flies live in the soil and feed on organic matter and fine root hairs, which can damage the developing taproot of your Tokyo Cross turnip. The presence of tiny black flies near the soil surface is a classic sign of high moisture levels attracting adults.
Certain species of small flies are attracted to the nitrogen-rich environment of decomposing organic matter used in turnip beds. While they don't feed on the turnip directly, their presence indicates a high-moisture substrate that can lead to secondary fungal issues.
While the flies themselves are the visible symptom, they often precede or accompany root maggot larvae that tunnel into the turnip bulb. This causes the characteristic swelling and eventual rot of the Tokyo Cross variety.
