Economic thresholds – Mirids in mungbeans

This threshold assumes all green, brown and crop mirids and broken backed bugs produce equivalent damage, and that third instar (wing buds are present) nymphs onwards are as damaging as adults.

See the Beatsheet’s mirid image gallery for pictures of different species and life stages.

Enter your estimated:

  • control cost per hectare (include both product and application)
  • crop value per tonne

to receive a break even threshold (where the benefit in saved yield is equal to the cost of the control measure) expressed in number of mirids/m2.
