Management

  • Tip of immature fruit and spreads upward.
  • Ashy conidia and conidiophores cover the rotted portion.
  • Imparting burnt ashy cigar-end appearance with a dark border.
  • Decay may extend up to one-third of the fruit but internal tissues develop a dry rot.
  • Conidia are hyaline, oblong to cylindrical, borne at the ends of tapering phialides, aggregated into rounded, mucilaginous transluscent heads.
  • The fungus – plant debris – microsclerotia.
  • Infected plant parts – irrigation water – implements.
  • The principal method of control is frequent manual removal and burning of dead flower parts and infected fruits.
  • Use of fungicide to control the disease is also recommended.
  • In the packhouse, care should be taken to cull infected fruits to avoid contaminating the washing water with spores.
  • Cigar-end rot is effectively controlled by covering the flower (immediately after emergence) with a polyethylene bag before the hands emerge.
