You can also apply fungicides or neem oil to prevent the spread of the disease.
Rust is another fungal disease that can infect Plagiobothrys tener var. subglaber, causing orange or brown spots on the leaves and stems. Rust can spread rapidly and cause defoliation if left untreated. To prevent rust, make sure the plant has good air circulation and avoid overhead watering. You can also apply fungicides or sulfur to manage the disease.
Common Pests
One of the most common pests that attack Plagiobothrys tener var. subglaber is aphids. Aphids are small, soft-bodied insects that suck sap from the plant, causing wilting, yellowing, and stunted growth.
