Why does your Tomato Master No. 2 F1 have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The most common cause of tiny black flies in tomato cultivation; the larvae live in the moist substrate and feed on organic matter and fine root hairs, which can damage the developing root system of Master No. 2 F1 plants.
Small flies may be attracted to the fermenting sugars of overripe or decaying tomato fruit near the base of the plant, laying eggs that lead to secondary rot.
While the adults are small, their presence is often marked by 'serpentine' white trails on tomato leaves; if these larvae cause significant damage, they may attract secondary scavenging flies.
