To control this disease, remove and destroy infected leaves immediately. Also, avoid wetting the leaves when watering the plant, as this can create a conducive environment for fungi growth.
Rust - rust disease is caused by a fungus that causes rust-colored pustules on the leaves of the plant. The disease can cause the leaves to turn yellow and even fall off. To control this disease, remove and destroy infected leaves and use fungicides. Make sure to follow the manufacturer’s instructions on the use of the fungicide.
Root Rot - Root rot is a fungal disease that affects the roots of plants, causing them to rot. The rot can cause the plant to wilt and eventually die. To control root rot, avoid overwatering the plant and ensure that the soil has good drainage. Also, remove and destroy infected parts of the plant.
Common Pests
Aphids - Aphids are small insects that feed on the sap of the plant. They can cause stunted growth, yellowing of leaves, and distortion of shoots and leaves. To control this pest, use insecticidal soap or oil, or introduce natural predators such as ladybugs and lacewings to the plant.
Thrips - Thrips are tiny insects that suck sap from leaves, causing them to turn white or brown. They can also transmit viruses that can cause further damage to the plant. To control this pest, use insecticides or introduce natural predators such as predatory mites or insect parasitic nematodes.
Mealybugs - Mealybugs are small, white insects that often appear in clusters on leaves and stems of plants. They feed on the sap of the plant, causing stunted growth and yellowing of leaves. To control this pest, use neem oil or introduce natural predators such as ladybugs and lacewings to the plant.
