A randomized controlled trial performed between 2017 and 2018 found that BT brinjal increased net yields by 51%. Bt brinjal farmers used smaller quantities of pesticides and sprayed less frequently. BT brinjal reduced the toxicity of pesticides by as much as 76%. Farmers growing BT brinjal and who had pre‐existing chronic conditions consistent with pesticide poisoning were 11.5% points less likely to report a symptom of pesticide poisoning.
