Complete Analysis of African Jasmine Disease Control
(T-J) Disease: The Culprit of Sunken Leaf Spots
The disease is most prevalent at the end of spring and beginning of summer, with light brown circular spots appearing on the leaves at the initial stage, which develop into sunken lesions with concentric rings as the condition progresses. Under a microscope, black conidial plates can be seen, which are the carriers of the pathogen spread by wind and rain.
Effective Control Plan: 1. Prune and burn diseased leaves in time. 2. Alternate spraying of benz醚甲环唑 and pyraclostrobin suspension. 3. Increase application of phosphorus and potassium fertilizers to enhance disease resistance.
Sunscald Disease: Essential Lesson in Light Management
When the intensity of ultraviolet light exceeds 2000μW/cm² in summer, young leaves are prone to gray-white burn spots. Special attention should be paid to newly transplanted plants, as their leaves have a thinner cuticle and are more easily damaged.
Environmental Regulation Techniques: - Use a sunshade net with 40% light blocking rate. - Spray the leaves with water to cool down during high temperatures. - Apply seaweed acid repair agent to the damaged plants.

Short-frons Grasshopper: Leaf Eater
This pest occurs 3-4 generations a year, with adult body length of 20-25mm, causing irregular notches after eating. The peak activity period is from 5-7 am, which is the best time for control.
Biological Control Strategies: • Hang yellow sticky traps to monitor pest density. • Release natural enemies such as Anthocoris spp. • Spray plant-derived pesticides such as matrine.
Golden Rules for Comprehensive Maintenance
Prevention is better than cure. It is recommended to conduct a comprehensive check once a month: 1. Check the back of the leaves for egg clusters. 2. Measure and maintain soil pH between 5.5-6.5. 3. Maintain environmental humidity at 60%-70%. 4. Rotate the pot regularly to ensure even lighting.
