Complete Guide to Pest and Disease Control for Epipremnum aureum
Chemical Control Method
When using broad-spectrum insecticides such as imidacloprid and abamectin, dilute them at a ratio of 1:1000 before spraying, focusing on the leaf undersides and the surface of the soil. It is recommended to apply the insecticides in the early morning or at dusk to avoid direct sunlight that may affect the efficacy.
Ecological Pest Repellent Solution
Soak 50g of dried tobacco leaves in 500ml of warm water for 8 hours, then filter out the residue and add 3 drops of dishwashing liquid to enhance adhesion. Crush 100g of garlic cloves with a food processor, mix with water and let it sit for 24 hours, filter the mixture, and then pour it into a spray bottle for use.
Deep Soil Treatment
Thoroughly remove the plant from the pot and rinse the roots with a high-pressure water gun, turn the soil every 2 hours while it is exposed to the sun for 3 consecutive sunny days. It is recommended to use a concentration of 1:800 for the carbendazim solution, water thoroughly, and then cover with plastic wrap to kill for 48 hours.

Environmental Control Points
In the summer, maintain an environment below 28°C, use a misting humidifier to keep the humidity at 60%, and ensure 4 hours of scattered light every day. In winter, avoid direct cold winds and keep at least 1 meter away from radiators.
Scientific Watering Plan
Use the "Two-Finger Test": Insert the index finger into the potting soil to a depth of two finger segments, and water when dry. For plants with accumulated water, tilt the pot 45 degrees to drain and use a fan to accelerate evaporation.
Root Repair Process
When pruning rotten roots, leave 1cm of healthy tissue, soak in a potassium permanganate solution for 20 minutes, and then plant in new soil containing perlite. During the acclimatization period, maintain 90% humidity with a plastic cover and gradually increase ventilation time.
Advanced Maintenance Techniques for Epipremnum aureum
When applying high-nitrogen liquid fertilizer monthly, it is recommended to dilute it to half of the standard concentration. Regularly wipe the leaves with beer diluted in water (1:20) to remove dust and replenish trace elements. By setting up yellow traps and regularly loosening the soil, you can effectively prevent pest recurrence.
Mastering these systematic solutions can not only address the current growth problems of Epipremnum aureum but also establish a scientific maintenance system. It is recommended to conduct preventive treatments every quarter to keep the plant in the best ornamental condition.
