Tiger Jasmine Diseases and Control
As a unique member of the succulent family, Tiger Jasmine is favored by horticulture enthusiasts for its hard thorns and colorful bracts. Although this plant, native to Africa, has strong resistance to adversity, disease and pest control is still necessary under special climatic conditions. This article systematically analyzes the common diseases and pests of Tiger Jasmine and provides a highly operational control plan.
Tiger Jasmine Disease Control System
Root Rot Control Plan
During the rainy season, be vigilant about soil compaction causing root rot. Initially, the plant's leaves turn yellow and fall off, and brown water-stained spots can be seen at the base of the stem. It is recommended to use a 50% carbendazim wettable powder 800 times solution to water the roots, combined with loosening the soil to increase aeration. It is suggested to use Bacillus subtilis biological preparations monthly for soil improvement.
Stem Rot Emergency Treatment
When soft rot lesions appear on the stem, immediately cut off the infected part to healthy tissue and apply sulfur powder to disinfect the incision. Use a 72% agricultural streptomycin 4000 times solution to spray the entire plant, repeating the application every 5 days. Focus on improving the cultivation environment, maintaining a daytime ventilation of >3 hours/day.
Tiger Jasmine Pest Control Strategies
Scale Insect Comprehensive Eradication
For the hidden scale insects between the thorns, a dual physical and chemical treatment is recommended. First, accurately kill the visible insects with a 75% alcohol cotton swab, then alternate the use of a 25% pymetrozine 2000 times solution and a 22% flonicamid suspension 1500 times solution, ensuring the back of the leaves is completely wet during application.
Whitefly Prevention System
Establish a yellow sticky board monitoring and warning system. When the insect count exceeds 50 on a single board, immediately use a 10% pyridaben wettable powder 1000 times solution to spray. It is recommended to plant insect-repelling plants such as mint and basil around the pot to form an ecological barrier.
Through scientific environmental regulation and standardized pesticide use, the disease resistance of Tiger Jasmine can be significantly improved. In daily maintenance, pay attention to controlling the watering frequency (7-10 days/week in spring and autumn, 15-20 days/week in winter), maintaining a day-night temperature difference of >8°C, and regularly pruning dense branches to enhance ventilation and light, these measures can fundamentally reduce the probability of diseases and pests.
