Disease Management
Lobelia elgonensis R.E.Fr. & T.C.E.Fr. is a hardy plant with resistance to many diseases. However, some diseases may affect the plant, such as Leaf spot and Powdery Mildew.
Leaf Spot: This disease is usually caused by the fungus Phyllosticta lobelio, and it can cause lesions on the leaves of the plant. To manage Leaf Spot, it is important to remove infected leaves and destroy them to prevent further spread of the disease. Additionally, it is important to keep the plant dry and avoid leaving the leaves wet, as this can promote fungal growth. Fungicides can also be used to manage Leaf Spot.
Powdery Mildew: A fungal disease that causes a powdery white covering on leaves, stems, and buds. It can reduce the plant's health and productivity. To manage Powdery Mildew, it is important to prune out infected areas, avoid overcrowding and provide good air circulation for the plant. Fungicides can also be used to manage Powdery Mildew.
Pest Management
Some pests may also affect Lobelia elgonensis R.E.Fr. & T.C.E.Fr. Below are some of the common pests and management techniques:
Whiteflies: These small pests can be found on the undersides of leaves, and they can cause yellowing, wilting and stunted growth in plants. To manage Whiteflies, it is important to remove any infected leaves and keep the plant well-watered. Insecticidal soap and neem oil can also be used to manage the pests.
Spider Mites: These pests are too tiny to be seen with naked eyes, but the first sign of infestation is usually the presence of webbing. They feed on the plant's sap, leaving behind yellow to white spots on leaves. To manage Spider Mites, it is important to keep the plant well-watered, prune and clean up the infected leaves and provide good air circulation. Insecticides can also be used to manage Spider Mites.
Aphids: These pests usually form colonies on the new growth of the plant, and they suck sap from the plant, causing curling, yellowing and stunted growth. To manage Aphids, it is important to remove infected leaves, prune out heavily infested areas and keep the plant well-watered. Insecticides can also be used to manage Aphids.
