3. Root Rot: This is a fungal disease that affects the roots of the plant, causing them to rot. It is caused by overwatering and poor drainage. To manage this disease, reduce the amount of water the plant receives and improve drainage.
Pests
1. Cactus Moth: This is a pest that lays its eggs on the cactus pads, and the larvae bore into the pads, causing damage. To manage this pest, remove the infected pads and dispose of them, and use insecticides to kill the larvae.
2. Spider Mites: These are tiny insects that suck the sap of the cactus pads, causing them to turn yellow and eventually die. To manage this pest, use a strong jet of water to dislodge them, and use insecticidal soap to kill any remaining insects.
3. Scale Insects: These are insects that produce a waxy coating on the cactus pads, causing them to turn yellow and die. To manage this pest, use a cotton swab dipped in alcohol to remove the scales, and use insecticidal soap to kill any remaining insects.
By following these disease and pest management practices, you can ensure the healthy growth of Opuntia juniperina Britt. & Rose plant.
