Disease and Pest Management for Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. typicus Cronq.
Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. typicus Cronq., commonly known as the native fleabane, is a beautiful perennial plant that requires low maintenance. However, it can still be affected by various diseases and pests that can cause significant damage. Below are some common diseases and pests that might affect the plant and suggestions on how to manage them.
Common Pests
Aphids: These tiny insects typically feed on young shoots and buds causing them to wilt and distort. They also produce a sticky substance called honeydew which attracts other pests like ants. To manage aphids, you can use a strong jet of water to wash them off the plant or apply insecticidal soap or neem oil.
Spider Mites: Spider mites are hard to spot with the naked eye, but they can cause extensive damage by sucking the sap from the leaves, causing them to turn yellow and die. To manage spider mites, you can spray the plant with neem oil or insecticidal soap and make sure to keep the plant well-watered.
Snails and Slugs: These pests are often active at night and feed on the leaves of the plant, creating holes and notches. To manage them, you can handpick them off the plant or use bait such as beer traps or copper tape around the base of the plant.
Common Diseases
Powdery Mildew: Powdery mildew is a fungal disease that can affect the leaves, stems, and flowers of the plant. It appears as a white powdery substance on the surface of the leaves, causing them to curl and become distorted. To manage powdery mildew, you can remove affected leaves and spray the plant with a fungicide containing potassium bicarbonate or neem oil.
Rust: Rust is another fungal disease that affects the leaves and stems of the plant, causing orange or yellow spots to appear. These spots eventually turn black, causing the leaves to drop off the plant. To manage rust, you can remove the affected leaves and destroy them, then spray the plant with a copper-based fungicide.
Root Rot: Root rot is a fungal disease that affects the roots of the plant, causing them to rot and decay. This is often caused by overwatering or poorly draining soil. To manage root rot, you can remove the affected plant and replace the soil, ensuring that the new soil is well-draining.
In conclusion, Erigeron subtrinervis Rydb. ex Porter & Britt. ssp. typicus Cronq. is a stunning plant that requires minimal maintenance. However, it can be challenged by various pests and diseases.
