Management of stem fly in the mungbean

  • Damage in yield by the stem fly in the mungbean crop has been reported to be  24-37%.
  • In India Stem fly infestation during the germination stage is predominant affecting crop produce posing a serious concern.
  • As this pest attacks during the initial stage of germination which is generally 4 weeks after sowing, this infestation results in wilting of leaves leading to crop loss.
  • Foliar spray of imidacloprid 17.8% SL @ 100 ml/acre OR Bifenthrin 10% EC @ 300 ml per acre may be sprayed to control stem fly.
