- What shape is the damage: round holes, only veins left, white trails, or a pale stippling?
- Where are the insects or droppings: under the leaves, on new shoots, or at the base?
- If nothing is visible by day, check at night or early morning for cutworms and slugs.
Most likely causes
From the pests and diseases recorded for this plant, the ones whose symptoms match, most serious first. Symptoms alone rarely confirm a cause, so use the linked page to check the signs and treatment.
Tobacco Cutworm
Many larvae gather on the leaf underside and graze the tissue away, leaving white skeletonized patches. Once they disperse they cause heavy damage to leaves, pods and fruit.
How to identify and treat: Tobacco CutwormStink Bugs
Small feeding punctures on fruit become sunken or turn spongy and discolored. On legumes the pods fail to fill, and fruit drop and deformity increase.

Emergence is uneven, and digging up seed reveals white maggots inside the seed or hypocotyl. In transplants the stem base rots and the plant wilts.

What other growers did about it
A page like this one can tell you what edamame pests and bug damage is and what to try. What it cannot tell you is what actually happened to someone who had it on the same plant, at the same point in the season, and what they did next.
Gadenin is a free garden journal built around that. You photograph the plant, tag what you are seeing, and the entries line up by date for each plant you grow.
- Tag the problem and the app tells you how many other growers have logged the same thing on the same plant.
- Growers who make their records public can be followed, so you can read what they did and how it turned out.
- Next season your own entries come back at the same point in the year, so you check the plant before it starts.
Free on iPhone. Recording, tagging and reading public records cost nothing.
