Reasons for White Fungi at the Roots of Epipremnum aureum
As a common indoor ornamental plant, Epipremnum aureum often experiences root white fungi problems due to improper care. This abnormal phenomenon not only affects the plant's growth but can also lead to the death of the entire plant in severe cases. This article provides detailed illustrations of the symptoms, systematically analyzes the causes of the disease, and offers targeted solutions.
Three Main Causes of White Fungi at the Roots of Epipremnum aureum
Fungal Infection Leading to Root Rot
If the cut is not disinfected during cutting propagation, soil-borne pathogens such as Fusarium fungi can easily infect through the wound. Under a microscope, white mycelium can be seen attached to the roots, which can cause browning and rot within 48 hours.
Humid and Warm Environment Inducing Fungi
When the maintenance temperature remains below 18°C and the air humidity is above 80%, combined with waterlogged soil, it creates the best environment for fungal reproduction. Experimental data shows that under these conditions, the reproduction rate of pathogens triples.
Poor Drainage of Substrate
When using heavy and compacted garden soil for cultivation, the roots are immersed in a moist environment with less than 5% oxygen for a long time, leading to root cell asphyxiation and death, which provides a substratum for fungal decay.
Comprehensive Management Plan for White Fungi in Epipremnum aureum
Three-Step Environmental Control Method
1.立体通风 (Three-dimensional ventilation): Maintain a plant spacing of >20cm, and open windows for ventilation for 2 hours daily. 2. 温控养护 (Temperature-controlled care): Maintain a growth temperature of 25-30°C, and use heating pads in winter. 3. 光照管理 (Light management): Provide 2000-3000lux scattered light to inhibit mycelium growth.
Scientific Water Management
Use the "wet and dry" watering method, combined with a mixed substrate of expanded clay aggregate layer + perlite accounting for 30%. When the topsoil is dry to a depth of 2cm, water thoroughly with slightly acidic water with a pH of 6.0.
Medication Treatment Process
Early Stage: Apply a solution of 1000 times the concentration of Metalaxyl, once every 7 days for 3 weeks. Severe Treatment: After pruning the roots, soak in a solution of 500 times the concentration of carbendazim for 30 minutes, then plant in new soil. Preventive Medication: Apply a biological preparation of Bacillus subtilis once a month to enhance resistance.
Through regular inspections, scientific care, and timely intervention, the white fungi problem at the roots of Epipremnum aureum can be effectively controlled. It is recommended to conduct root health checks every quarter, gently scrape the root surface with a bamboo skewer, and normal roots should appear milky white and plump. Establishing a preventive care system is essential to ensure the long-term healthy growth of Epipremnum aureum.
