Root Rot
Pythium spp., Rhizoctonia solani

  • Leaves turn yellow and wilt
  • Plants are stunted
  • With Rhizoctonia sp., the base of the stem may turn brown and crack
  • Roots have brown sunken areas and lack root hairs
  • The outer root tissue is easily removed leaving behind thin, stringy root cores.
  • Disease favors cool, wet soil with poor drainage
  • Lab test necessary to distinguish between Rhizoctonia and Pythium Root Rot

  • Impatiens Necrotic Spot Virus 1
  • Impatiens Necrotic Spot Virus 2
  • Impatiens Necrotic Spot Virus 3

Impatiens Necrotic Spot Virus (INSV)

  • Symptoms are extremely variable
  • Stunted growth and wilting may occur
  • Leaf distortion; ringspots or black spots on leaves and stems; blackish/purplish coloration along leaf veins
  • Tip dieback and in some cases entire plant will collapse
  • Lab test needed to identify INSV since it is difficult to diagnose on symptoms alone
  • More information on INSV
