Monitoring for Pest & Disease

  • Organise regular pest and disease monitoring and assess bio-control potential at 15 days intervals.
  • Observations are taken at every 5 to 10 km distance, 10 spots per ha randomly and 10 plants per spot.
  • Install pheromone traps 10 per ha to monitor moth population of Helicoverpa and Spodoptera  litura.  

Pre-sowing stage 

  • Deep summer ploughing
  • Clean cultivation
  • Seed treatment with T. harzianum of T. viride @ 4 g/kg seed for diseases.
  • Soil application of Verticillium chlonydosperium @ 2 Kg/ha along with compost followed by irrigation for nematode management.

Sowing stage

  • Use resistant varieties
  • Use certified disease free seed
  • Early sowing
  • Sow the crop in ridges at 15-20 cm height in cutworm endemic areas.
  • Use mechanical devices to scare parakeets.
  • Rogue downy mildew and sunflower necrosis disease infected plants and destroy them.

Vegetative stage 

  • Conserve biocontrol agents like Cotesia spp., spiders, anthocorids, Chrysopa, Lady bird beetles, mandits and reduvid bugs.
  • Install 15 bird perches per hectare for predatory birds.
  • Release 1-2 larva per plant of Chrysoperla carnea at early stage of crop.

Flowering stage

  • Use NPV @ 250 LE/ha against Helicoverpa and Spodoptera .
  • Use B.t. (K) 1 kg/ha against Spodoptera.
  • Release 1-2 larva per plant of Chrysoperla carnea at early stage of crop
  • Conserve bio-control agents like Cotesia spp., spiders, anthocorids, Chrysopa, Lady bird beetles, mandits and reduvid bugs.
