Carrots · Symptom guide
Bugs on carrot plants
Bugs on carrot plants in a garden bed are a look-and-compare job. Cited sheets list six-spotted leafhopper as observations, not a ranked or confirmed cause. This page does not diagnose, name a spray, or sell a treatment.
Cited observations are comparisons—not a confirmed diagnosis. Check the cited sources and local requirements before taking action.
Save this bed. See it coming next year.
Your checks stay in the Field Book so next season is not a guess.

Look
Compare the plant in front of you with the cited notes after Other causes. Leaf marks alone do not name a cause on this page.
Other causes
Growing notes live on how to grow carrots. Garden-wide looks live on garden pests. Tomato hornworm is a separate species page — not this crop-pest list.
