Diseases
Downy Mildew: This disease is caused by a fungus and is characterized by yellowing of the leaves, the presence of a grayish white mold on the undersides of leaves, and leaf drop. To manage downy mildew, plant resistant varieties, avoid overhead watering, ensure good air circulation, and remove infected leaves or plants immediately.
Cercospora Leaf Spot: A fungus causes this disease. It appears as dark brown spots with yellow halos on lower leaves. Leaves can drop prematurely, and the plant can become weak. To manage this disease, remove infected leaves, ensuring to keep the plant well watered, and avoid wetting the leaves when watering.
Phytophthora: It's a root rot disease characterized by yellowing, wilting and visible fungal growth on the stem and rot of the root system. To manage phytophthora, remove and discard infected plants immediately, avoid overwatering and ensure a well-draining soil.
Pests
Aphids: These small insects feed on the plant sap, causing yellow, stunted leaves. They are often present in colonies on shoots, buds, and leaves. To manage aphids, spray the plants with a powerful stream of water, apply insecticidal soap or neem oil, or introduce natural enemies like ladybugs or lacewings into your garden.
Spider Mites: They are tiny arachnids that feed on the plant's sap, resulting in yellow and brown leaves and poor growth. They thrive in hot, dry conditions, and infestations can happen quickly. To manage spider mites, spray plants with water or neem oil regularly. Also, ensure to keep the humidity high by placing a tray of water near the plant or by misting it regularly.
Slugs and Snails: These pests feed on the new growth, leaving behind holes in the leaves. They are often active at night and hide during the day. To manage slugs and snails, remove hiding places like debris and dense foliage around the plants. Additionally, hand-pick the pests or use traps, like beer traps or copper barriers, to ward them off.
Regular inspections and prompt action are crucial in keeping your Impatiens wittei G.M.Schulze healthy and free of pests and diseases. Remember to monitor your plants' condition regularly, and practice good sanitation to prevent diseases or pests from taking hold.
