Pacific Pests, Pathogens and Weeds


  • Worldwide distribution. In tropics. On tomato, capsicum, chilli, and eggplant. An important disease.
  • Dark fungal patches on lower leaves progressing upwards. Leaves turn yellow rapidly and die. Fruits are not infected.
  • Spores on underside of leaves spread in wind-blow rain.
  • Cultural control: avoid planting next to old crops; remove and burn leaves as infections occur; seek advice on tolerant varieties; 3-year crop rotation; collect trash and burn after harvest.
  • Chemical control: copper, chlorothalonil, or mancozeb (protectants). Begin when flowers appear, then at 10-14 day intervals until 3-4 weeks from harvest. Note that mancozeb has a 5-day withholding period.
