Leaf Spot
Leaf spot is a fungal disease that manifests as circular, brown spots on the leaves of the plant. As the disease progresses, the spots become larger and can merge together, causing the affected leaves to turn yellow and eventually fall off. To manage this disease, it is important to remove the affected leaves and treat the plant with a fungicide.
Root Rot
Root rot is a fungal disease that affects the roots of the plant and causes them to rot. This can be caused by overwatering or poor drainage. Symptoms of root rot include wilting, yellowing of leaves, and a foul odor coming from the soil. To manage this disease, it is important to remove the affected roots and repot the plant in fresh, well-draining soil.
Powdery Mildew
Powdery mildew is a fungal disease that appears as white powdery spots on the leaves of the plant. This disease is usually caused by high humidity and poor air circulation. To manage this disease, it is important to improve air circulation, reduce humidity, and treat the plant with a fungicide.
Pests
The following are some of the most common pests that can affect Streblocarpus pubescens Klotzsch:
Spider Mites
Spider mites are small pests that can be identified by the webbing they leave behind on the leaves of the plant. They suck the sap from the leaves, causing them to turn yellow and wilt. To manage spider mites, it is important to regularly mist the plant to improve humidity and wash the leaves with a gentle soap solution.
Mealybugs
Mealybugs are small, white, and fuzzy pests that can be found on the leaves and stems of the plant. They secrete a sticky substance that attracts ants and can cause the leaves to turn yellow and drop off. To manage mealybugs, it is important to remove them manually and treat the plant with a pesticide if necessary.
Fungus Gnats
Fungus gnats are small, black, flying insects that can lay their eggs in the soil of the plant. The larvae of the fungus gnats can feed on the roots of the plant, causing them to weaken.
