How to deal with clivia macular disease
As a deeply loved indoor ornamental plant, the yellow spot problem of Clivia leaves often troubles conservators. Macula not only affects ornamental value, but also serves as a warning signal for plant health. This article systematically analyzes the causes of macular spots and provides scientific prevention and control plans. 1. The pathogenesis of Clivia mpolopathy 1.1 External environmental damage and direct exposure to strong light are the primary cause of leaf surface burns. Especially at noon in summer, sunlight can cause scorched yellow patches on leaves. Direct cold wind blowing in winter will cause frostbite and form stripe spots. 1.2 Insect-induced infection Wounds formed by slugs and snails are susceptible to infection by Fusarium. The periphery of the bite mark visible to the naked eye will gradually expand to form an irregular yellow-brown lesion of 3- 5 cm. 1.3 When the root system is improperly maintained, the pot soil is hardened or long-term water accumulation causes rotten roots, the plant sends a distress signal through yellowing of the leaf tips. If not treated in time at this time, the yellowed parts will spread downward. 2. Systematic prevention and control of clivia maculopathy 2.1 Light and temperature regulation Ensure that light is scattered for 4 hours a day in spring and autumn, and 70% of light is blocked in summer. Maintain the ambient temperature of 15-20 ° C in winter to avoid drastic changes in hot and cold. 2.2 In the early stage of the disease, the scientific medication plan used a mixture of 50% carbendazim 800 times solution and 72% agricultural streptomycin 4000 times solution, and sprayed once every 10 days. In severe cases, cooperate with root irrigation and use 1000 times thiophanate-methyl solution. 2.3 Tips for root maintenance When changing pots every spring, use pine needle soil: leaf soil: river sand =4:4:2 to prepare the substrate. Daily watering adheres to the principle of "seeing wet when it is dry", and the bottom of the basin is padded with 3cm ceramite to enhance ventilation.
Through a three-pronged approach of environmental regulation, pest control, and scientific maintenance, the development of maculopathy can be effectively controlled. It is recommended to wipe the leaves with beer diluent every month, which can not only remove dust but also replenish amino acids. Coordinate with regular pot rotation to ensure symmetrical growth of the leaves, so that Clivia can regain its green and straight appearance.
