  • 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
