Here we share some small gardening knowledge about the introduction and control methods of Epipremnum aureum leaf disease, and we will get to know it together next.
Epipremnum aureum leaf disease is a common plant disease. In the early stage of the disease, the leaves of the plant will show chlorotic angular spots, which gradually turn into brown. In severe cases, it can cause leaf deformation, yellowing, stunted plant growth, short flower spikes, fewer and smaller flowers, or even fail to produce flower spikes. Therefore, we need to prevent the occurrence of Epipremnum aureum leaf disease. Many flower enthusiasts are not very familiar with it. Below is a comprehensive introduction to the disease and its control methods.
Distribution and Harm
It occurs to varying degrees in different Epipremnum aureum cultivation and introduction areas. When the disease is mild, yellow streaks appear on the leaf surface, and some people cultivate it as an ornamental variety. When the disease is severe, the leaves often turn brown and die from the yellow streaked edges, gradually extending to the veins, severely affecting ornamental value.
Symptoms
The disease harms the leaves of Epipremnum aureum, showing symptoms from the tender leaves, often with several wide and narrow chlorotic yellow bands along the lateral veins on one side of the main vein. As the leaves grow, the yellow bands gradually become wider and longer, the color changes from bright yellow to brown or even brown and crispy dead.
Cause
Virus, the group is yet to be determined.
Incidence Regularity
The whole plant is virus-infected, and new plants propagated by cutting or stem burial methods still get the disease.
Preventive and Control Measures for Epipremnum Aureum Leaf Disease
▲ Strengthen cultivation management, enhance growth potential, which can reduce the severity of the disease. Epipremnum aureum prefers loose, organic-rich, slightly acidic to neutral sandy loam. You can use a mixture of 7 parts of decomposed leaf soil, 2 parts of acidic loam, and 1 part of rapeseed cake and bone meal. Change pots every 3 years. Epipremnum aureum is a shade-tolerant plant that likes scattered light and avoids direct sunlight. It usually grows best with 4 hours of scattered light per day. It prefers a humid environment, and in the hot summer, you can spray the leaves and aerial roots several times a day, which not only cleans dust but also keeps the leaves green and lush. The most suitable growth temperature is 25-28°C during the day and 15-18°C at night, with the minimum winter temperature not lower than 15°C. If the temperature is below 5°C, it can cause leaf drop. Fertilization is mainly with nitrogen fertilizer, supplemented by potassium fertilizer. In spring and summer, apply ammonium sulfate or 0.3% urea solution once every 10 days, and use 0.1% urea solution as foliar fertilizer.
▲ Do not collect propagation materials from diseased plants to propagate new plants.
▲ Do not purchase or introduce diseased plants.
