How to control Bacterial leaf spot disease in chilli crops

  • The leaves exhibit small, circular or irregular, dark brown or black greasy spots. As the spots enlarge in size, the centre becomes lighter, surrounded by a dark band of tissue.

  • The spots coalesce to form irregular lesions, Severely affected leaves become chlorotic and fall off. Petioles and stems are also affected.

  • Stem infection leads to the formation of cancerous growth and wilting of branches. On the fruits, round, raised water-soaked spots with a pale yellow border are produced.

  • The spots turn brown, developing depression in the centre where shiny droplets of bacterial ooze may be observed.

  • Control- The residues of the old crop should be removed from the field. Also, seeds should be obtained from disease-free plants.

  • The nursery should be raised on the soil where chillies were not grown for several years.

  • For its chemical control, spray Kasugamycin 5% + Copper Oxychloride 45% WP @ 300 g/acre or Streptomycin Sulphate 90% + Tetracycline Hydrochloride 10% W/W @ 24 g/acre or spray.
