Research conducted the study funded by Agricultural Extension Division of Indian Council of Agricultural Research under extramural project “Impact evaluation of integrated pest management technologies”. Study found that, since the commercialization of BT cotton,

  1. Insecticide use by volume & applications, environmental & human health impact associated with insecticide use and use of highly hazardous & riskiest insecticides has reduced over time.
  2. Expenses associated with insecticide use has also reduced.
  3. Cotton yields in the past 13 years have been stable, except in 2015.
