The roots of the infected plant turn brown or black and become mushy, leading to the death of the plant.
To prevent root rot, it is essential to ensure that the soil is well-draining and the plant is not overwatered. Water the plant only when the soil has dried out completely. Avoid getting water on the foliage as it can lead to the development of other fungal diseases.
Another common disease that affects Euphorbia multiformis Hook. & Arn. var. manoana Sherff is powdery mildew. Powdery mildew appears as a white, powdery coating on the foliage of the plant. It can weaken the plant over time and affect its overall health.

Spider mites are small insects that feed on the sap of the plant and can cause yellowing and drooping of leaves. Mealybugs are small, white, fluffy insects that also feed on the sap of the plant and can cause stunted growth and yellowing of foliage. Scale insects are small, oval-shaped insects that feed on the plant's sap and can cause yellowing and wilting of the leaves.
To manage pest infestations, you can wash the plant with a solution of water and mild soap. You can also use a systemic insecticide to control the pests. Regularly inspect the plant to identify any infestations early and take necessary action to prevent the spread of the pests.
By following these disease and pest management strategies, you can ensure that your Euphorbia multiformis Hook. & Arn. var. manoana Sherff remains healthy and thrives in your garden.
