Air humidity >80% and excessive nitrogen fertilizer are the main causes. It is recommended to spray preventively with Mancozeb solution every quarter, and when the disease occurs,配合修剪 to maintain a well-ventilated plant shape.
Black Rot: Hidden Killer in Summer
When water-stained black spots appear on the stems, it is often a sign of black rot infection. In addition to high temperature and humidity, root hypoxia caused by compacted planting soil is also an important cause.

White Powder Scale: Wax-Coated Pest
This pest with a white waxy shell often forms cotton-like nests in the leaf axils. In addition to chemical control, you can regularly wipe the stems with a 75% alcohol cotton swab, especially paying attention to the key control window period of the larval hatching in spring. For severely infected plants, it is recommended to perform a full plant root washing.
By establishing a monthly pest and disease inspection system, combined with environmental regulation (maintaining a day-night temperature difference >8°C, humidity <65%), more than 90% of pests and diseases can be effectively prevented. Remember that prevention is better than cure, and regularly rotating the use of biological pesticides and mineral oil preparations can not only ensure control effectiveness but also avoid the development of resistance.
