Technical and Methodological Measures for the Control of Flower Diseases and Pests
This article provides an overview of topics related to the cultivation of flowers, focusing on techniques and measures for controlling flower diseases and pests. Please see the detailed introduction below.
Technical and Methodological Measures for the Control of Flower Diseases and Pests
Common diseases and pests in home-grown flowers include powdery mildew, grey mold, (T-J) disease, damping-off, scale insects, red spiders, aphids, leafhoppers, and moths, among others. The general approach is to spray pesticides promptly for disinfection and sterilization, or to adopt pollution-free control methods such as spreading wood ash around the pot, wiping with vinegar, and applying alcohol to disinfect.
Common Diseases in Flower Cultivation
1. Powdery Mildew: Flowers often suffer from powdery mildew during maintenance. After the onset of the disease, leaves, petioles, peduncles, or young shoots will have a white powdery substance. Leaves will turn yellow, curl, and eventually die, causing significant damage to the plant.
2. (T-J) Disease: (T-J) disease is common in many flower cultivation processes. When the disease occurs, numerous lesions and small black spots appear, and in severe cases, the plant may die. Typically, (T-J) wettable powder can be sprayed for control.
Major Pests in Flower Cultivation
1. Snails: They can be found near potted plants, especially on rainy days, particularly on evergreen ornamental foliage. They damage important parts of the plant, including leaves, young buds, and new roots, leaving the leaves incomplete and preventing young seedlings from growing healthy new roots.
2. Aphids: These are important vectors for viruses and bacteria, primarily affecting newly sprouted leaves of flowers, leading to complete defoliation. As temperatures rise, these pests multiply rapidly.
3. Red Spider Mites: Red spider mites are small and prefer to congregate on the undersides of leaves. Affected leaves turn from yellow to white, and eventually wither and fall off, mainly affecting ornamental flowers such as roses and begonias.
4. Whiteflies: These pests can be found on many types of flowers, with the poinsettia being particularly severely affected. They are small, white, and often hide on the undersides of leaves, feeding on the sap inside. Affected leaves start to turn yellow and may develop rot.
5. Scale Insects: These pests are among the most common and diverse in indoor ornamental foliage, preferring to congregate on young leaves. They have a high reproductive capacity.
