Disease Management
Celosia argentea L. var. cristata is prone to several diseases that can impact its growth and productivity. The following are some common diseases that affect the plant and ways to manage them.
Anthracnose
Anthracnose is a fungal disease that causes plant tissue to die. The symptoms include small, circular lesions that can be reddish-brown or dark-brown in color. To manage anthracnose, remove and destroy infected plant debris, avoid overhead watering, and apply fungicides to protect the plant.
Powdery Mildew
Powdery mildew is a fungal disease that produces a white or grayish powdery coating on the plant's leaves. The disease can cause the leaves to curl, wilt, and eventually die. To manage powdery mildew, keep the plant in well-circulated areas with good light and air circulation. Additionally, remove infected leaves and apply fungicides to reduce the spread of the disease.
Root Rot
Root rot is a fungal disease that occurs when the soil is too wet. The disease attacks the roots and causes them to rot, leading to the plant's eventual death. To manage root rot, avoid overwatering and remove any dead or damaged roots. Additionally, apply fungicides to the soil and replant the plant in a well-drained location with fresh soil.
Pest Management

Spider Mites
Spider mites are tiny, red or yellow arachnids that feed on the plant's sap. Infested leaves will look yellow and have a dusty appearance. To manage spider mites, keep the humidity high and the air circulated around the plant. Additionally, wash the leaves with water and apply insecticidal soap or neem oil.
Thrips
Thrips are small, elongated insects that feed on plant sap, causing leaves to become curled, distorted, and discolored. To manage thrips, remove and destroy infested plant debris, use yellow or blue sticky traps, and release natural predators like predatory mites.
