Understanding Fungal Infections on Castor Bean Plants

Before we dive into how to get rid of fungus on castor bean plants, it’s essential to understand what causes fungal infections. Fungal infections can occur due to a variety of factors, including poor air circulation, high humidity levels, and overwatering. In addition, fungal spores can be spread by wind, water, or insects.

Common fungal infections on castor bean plants include powdery mildew, downy mildew, and rust. Powdery mildew appears as a white or grayish powder on the leaves and stems of the plant. Downy mildew appears as yellowish spots on the leaves, which eventually turn brown. Rust appears as orange or brown spots on the leaves.
