Drumstick Diseases

Damping off

Disease symptoms:

Disease of nursery beds and young seedlings resulting in reduced seed germination and poor stand of seedlings. Very high seedling mortality of 25-75%.

  • Pre-emergence damping off: Seedlings disintegrate before theyDrumstick Damping off come out of soil surface leading to poor seed germination
  • Post-emergence damping off is characterised by development of disease after seedlings have emerged out of soil but before the stems are lignified
  • Water soaked lesion formation at collar region
  • Infected areas turn brown and rot
  • Plants shrivel and collapse as a result of softening of tissues
  • In Rhizoctonia solani attack infected stems become hard, thin (wire stem symptoms) and infected seedlings topple Disease appear in patches both in nursery and field beds.

For Rhizoctonia

  • High soil moisture with temp around 30–35°C

Twig canker

Disease symptoms:
  • The first symptom of the disease is clearing of the veinlets and chlorosis of the leaves.
  • The younger leaves may die in succession and the entire may wilt and die in a course of few days.
  • Soon the petiole and the leaves droop and wilt.
  • In young plants, symptom consists of clearing of veinlet and dropping of petioles.
  • The symptoms continue in subsequent leaves.
  • At later stage, browning of vascular system occurs.
  • Plants become stunted and die.
Survival and spread:
  • Soil and implements
Favourable conditions:
  • Relatively high soil moisture and soil temperature
