Yes, avocado can generally be eaten by Jains.

• Avocado is a tree fruit, not a root (kand-mool), so plucking it does not kill the whole plant.
• On this basis, it is normally permitted in a Jain diet, especially for householders, as long as:

- It is fresh (not overripe or fermented), - Carefully checked and cleaned, - Free from insects or infestation. ( jainknowledge.com)
