Cultural control

  • Deep summer ploughing in 2-3 years to eliminate quiescent pupa.
  • Early sowing, short duration varieties.
  • Avoid closer plant spacing.
  • Grow tall sorghum as comparison crop to serve as biological bird perches
  • Collect and destroy larvae and adults to the extent possible
  • Install pheromone traps at a distance of 50 m @ 5 traps/ha for each insect pest.
  • Install Bird perches @ 50/ha.
  • Setting of light traps (1 light trap/5 acre) to kill moth population.
  • Control is achieved by releasing of Trichogramma chlionis at weekly intervals @1.5 lakh/ha/ week for four times.
  • Conserve green lacewing, predatory stink bugs, spider, ants
