Pests, Diseases & DisordersHow can potato pieces help investigate fungus gnat larvae in mango containers?
Fresh potato pieces placed against the medium can attract larvae for inspection beneath them. Tag the sampled pots, use a consistent brief observation period, and remove the pieces afterward. Look for translucent larvae with dark head capsules and obtain identification if uncertain. This is a monitoring aid, not a reason to leave decomposing food permanently around the roots.
