In this article, we will explore the possible reasons why your cantaloupe plant might have brown spots and what you can do to remedy the situation.

Reasons for Brown Spots on Cantaloupe Plants

1. Fungal Infections

Fungal infections are a common reason why cantaloupe plants develop brown spots. These infections can be caused by various fungi, including Alternaria cucumerina and Colletotrichum orbiculare. Fungal infections can occur due to high humidity levels or wet conditions.
