Symptoms

  • Pustules appear first on the lower surface and in highly susceptible cultivars the original pustules may be surrounded by colonies of secondary pustules
  • Pustules may also appear on the upper surface of the leaflet
  • They may be formed on all aerial plant parts apart from flower and pegs. Severely infected leaves turn necrotic and desiccate but are attached to the plant

Management

  • Deep ploughing to bury surface litter, cultivation of groundnut in flat or lightly raised beds
  • Seed treatment with Trichoderma viride @ 4 g/kg seed and soil application of Trichoderma viride @2.5 kg/ha, mixed with 50 kg FYM or in conjunction with organic amendments such as castor cake or neem cake or mustard cake @ 500 kg/ ha
