Anthurium (Anthurium spp.)

Bacterial blight (Xanthomonas campestris pv. dieffenbachiae)

Symptoms

  • Rapid and complete chlorosis, browning, and then death of plant tissues.
  • Blackening of the stem, decay of leaf axils and leaf blight.
  • In the humid tropics, high rainfall coupled with year-round high temperatures increases the severity and spread of bacterial blight disease.

Management

  • The most effective control measure for bacterial blight disease is the use of resistant cultivars.
  • Spray a mixture of turmeric powder and sodium bi-carbonate in the proportion 10:1 (2 gram/litre of water) at weekly interval from the initiation of the disease.
  • In severe cases spray Streptocycline (0.5 gram/litre of water).
