Common Jasmine Plant Damaging Diseases

Important Points for Beginners to Identify and Manage Common Jasmine Plant Damaging Diseases

  • Identifying the disease: The first step is identifying the disease infesting your jasmine plant so that you can approach it with the most effective control method.
  • Regular Monitoring: Monitor your Jasmine plants regularly for signs of diseases. This will help you to identify an infestation early when it is easier to control.
  • Sanitation: Remove the infected plant debris and burn them.
  • Natural Control: Several natural control methods can help to manage diseases. These include plant extracts, essential oils, composting, and organic fungicides.
  • Chemical Control: If natural controls are ineffective, use fungicides as a last resort, and follow the label instructions and dosage carefully.

Phyllody Disease in Jasmine Plant

Disease Symptoms by Phytoplasma: Phytoplasma are bacteria-like microorganisms that infect plant phloem tissue. Infected plants show abnormal floral development, where petals, stamens, and pistils are transformed into leaf-like structures, greenish flower clusters, excessive branching, bushy appearance, discoloration, and stunted growth.

Survival and Spread: Phytoplasma prefers a warm environment of 20-30°C for dispersal. They are primarily transmitted by insect vectors, mainly leafhoppers, and planthoppers. Weeds act as reservoirs allowing them to survive and multiply.

Treatment, maintenance, and Control Measures: Spray carbaryl, methomyl, imidacloprid, thiamethoxam, malathion, and chlorpyrifos.

Collar Rot Disease in Jasmine Plant

  • Disease Symptoms by Sclerotium rolfsii: The lower stem develops lesions or cankers at the collar region, causing decay, rotting, and girdling of the collar region. Infected plants often show signs of wilting, chlorosis, stunted growth, and death.
  • Survival and Spread: Sclerotium rolfsii prefer warm temperatures and moist conditions of 25-30°C and 80% humidity for their growth and reproduction. Plant stress, overwatering, poor drainage, poor structure, acidic to neutral soil (pH 5.5 to 7), or plant debris can contribute to the disease.
  • Treatment, Maintenance, and Control Measures: Spray carbendazim, metalaxyl, propiconazole, tebuconazole, copper oxychloride, azoxystrobin, and thiophanate-methyl.

Rust Disease in Jasmine Plant

  • Disease Symptoms by Puccinia spp.: The first noticeable symptom is the appearance of rusty or reddish-brown bumps on the stem, leaves, and flowers. The infected leaves show chlorosis, wilting, premature defoliation, and spore dispersal.
  • Survival and Spread: Puccinia spp prefers a mildly warm and humid climate of 15-25°C and >75% humidity. Prolonged leaf wetness, dense canopy, overhead irrigation, and poor airflow contribute to the disease.
  • Treatment, Maintenance, and Control Measures: Spray copper hydroxide, copper oxychloride, copper sulfate, azoxystrobin, thiophanate-methyl, propiconazole, tebuconazole, chlorothalonil, sulfur, and mancozeb.

Powdery Mildew Disease in Jasmine Plant

  • Disease Symptoms by Erysiphe cichoracearum: The characteristic symptom of the disease is the white or grayish powdery fungal growth on the leaves, stems, and flowers. Infected leaves show a powdery or dusty appearance, distortion, stunted growth, chlorosis, curling, and drop prematurely. Infected flowers will fail to open properly.
  • Survival and Spread: Erysiphe cichoracearum prefers moderate
