Green Bell Disease and Control Methods
Green Bell, as a pendant star in the succulent plant world, is deeply loved by flower enthusiasts for its unique bead-like leaves. However, during the maintenance process, it often encounters the invasion of pests and diseases, which can affect the ornamental value and even lead to the death of the plant. This article deeply analyzes the identification characteristics and systematic control methods of cottony cushion scale, sooty mold, and stem rot through three sets of real-shot comparison pictures.
Green Bell's Three Major Disease Diagnosis Atlas
Cottony Cushion Scale: The Vampire of the Plant World
This orange-colored pest often聚集 in leaf axils, and the honeydew it secretes can cause secondary infections. Affected plants will show typical symptoms such as yellowing leaves and withered branches, and the white wax powder on the back of the pest is a distinctive identification feature.
Sooty Mold: The Killer of Photosynthesis
It initially presents as brown mold spots on the leaves and forms a soot-like covering layer as the condition progresses. This disease can reduce the photosynthetic efficiency of the plant by 70%, and it often occurs during the plum rain season or in environments with poor ventilation.
Stem Rot: A Hidden Fatal Crisis
The dark brown rot starting from the base of the stem is often mistaken for a symptom of water deficiency. Diseased plants will show progressive yellowing and withering of leaves, and soil-borne bacteria are the main route of transmission.
The Golden Four-Step Method for Disease Control
Environmental Control: Prevention is Better Than Cure
Maintain 50-60% environmental humidity, ensure at least 4 hours of direct sunlight (not through a window) daily, and use ceramsite mulch to enhance the breathability of the growing medium.
Physical Control: Three-Step Cleaning Technique
1. Remove虫卵 with bamboo sticks 2. Clean soot stains with a soft bristle brush 3. Irradiate with UV light twice a week (15 minutes each time)
Biological Control: Natural Guardians
Chemical Control: Precision Medication Guide
Cottony Cushion Scale: 50% flonicamid 2000x solution (focus on spraying the back of the leaves), Sooty Mold: 25% pyraclostrobin 1500x + organic silicon additive, Stem Rot: Metalaxyl + Metalaxyl-M mixed drench (every 7 days, for 3 consecutive times)
Advanced Maintenance: Building Disease Resistance
Apply seaweed extract monthly to improve stress resistance, and increase the application of potassium silicate in spring and autumn to strengthen the cell walls. Establish a disease monitoring log to record temperature, humidity, and disease correlation data. When the environmental temperature exceeds 30°C, activate the forced ventilation system.
By establishing a complete prevention-identification-intervention control system, the incidence of Green Bell plant diseases and pests can be reduced by 80%. It is recommended to save this article's illustration-based visual diagnostic library, conduct regular plant health inspections, and keep your Green Bell always maintaining its jade-like healthy luster.
