  • The field trials of two kinds of genetically modified (GM) maize are expected to begin in the ongoing kharif (summer) season at Punjab Agricultural University in Ludhiana.
  • The Genetically Modified (GM) maize has herbicide tolerance (HT) and insect resistance (BT).
  • Developed by Bayer, this maize variant is under biosafety trial phase BRL-I and BRL-II.
  • The trials will study weed-control efficacy in herbicide-tolerant maize hybrids with the application of the Glyphosate-K salt, and the efficacy of insect-protected maize hybrids against targeted lepidopteran pests.
  • In 2018, the Punjab government banned the sale of glyphosate, an herbicide used extensively in the State to control a wide variety of weeds in almost all crops.
  • It was a day after the Genetic Engineering Appraisal Committee (GEAC) gave the nod for the trials, after receiving consent from the Punjab government.
  • The GEAC functions in the Ministry of Environment, Forest and Climate Change (MoEF&CC) and is the country’s top regulator for the GM crops sector.
  • GEAC is the statutory committee framed under the Environment (Protection) Act, 1986.
