Where do Fungus Gnats cause the most damage?

Young cuttings
1st transplant
Flowers

Correct Answer

A. Young cuttings

Explanation

Fungus gnats cause the most damage to young cuttings. This is because the larvae of fungus gnats feed on the roots of plants, which can lead to stunted growth, root rot, and even death. Young cuttings have delicate and vulnerable root systems, making them an ideal target for these pests. Additionally, the presence of fungus gnats can also attract other harmful insects and diseases, further exacerbating the damage caused to the young cuttings.
