Symptoms

• Stump or brown root-rots: affected bushes show a gradual yellowing of leaves and defoliation and death. Affected roots are brittle and show dark brown wavy lines of the fungus.
  
• Fusarial root rot or wilt: a sudded wilting and yellowing of leaves leading to defoliation and death of aerial parts. Roots turn brown to pinkish.

Management

• Burn the plants at site, isolate affected patches by digging deep trenches, ring the bark and poison the shade trees while thinning.
• Remove the affected plants and treat the soil at 1kg lime per plant to raise the soil pH.
• Treat the soil around the affected area with PDCB or brassicol at 0.4%. Maintain the vigour of plants.
