Why does your Raphanus sativus 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 radish taproot. The presence of tiny black flies is a primary indicator of high moisture levels in the growing medium.
While typically attracted to decaying organic matter, these flies may congregate around radish crops if there is fermenting plant debris or overripe compost in the garden beds. They are less likely to damage the radish itself but indicate an environment prone to decay.
While the flies themselves are small, their larvae tunnel into the radish root, causing lesions that can attract secondary scavengers and small Diptera. This causes visible hollowed-out areas or soft spots in the radish bulb.
