• A group of more than 1,000 farmers gathered in a village in Akola of Maharashtra to sow seeds of an unapproved, genetically modified variety of cotton, defying government regulations. The government is now investigating what was planted.

Bt Cotton:

• Bt Cotton is developed by Bayer-Monsanto and it involves insertion of two genes viz ‘Cry1Ab’ and ‘Cry2Bc’ from the soil bacterium Bacillus thuringiensis into cotton seeds.
• This modification codes the plant to produce protein toxic to Heliothis bollworm (pink bollworm) thus making it resistant to their attack. The commercial release of this hybrid was sanctioned by the government in 2002.
• Bt cotton remains the only GM crop allowed to be cultivated in the country.

India and GM Crops:

• In India, it is the responsibility of the Genetic Engineering Appraisal Committee (GEAC) under the Environment Ministry to assess the safety of a genetically modified plant, and decide whether it is fit for cultivation. The GEAC comprises experts and government representatives, and a decision it takes has to be approved by the Environment Minister before any crop is allowed for cultivation.
• Besides Bt cotton, the GEAC has cleared two other genetically modified crops — brinjal and mustard — but these have not received the consent of the Environment Minister.

Farmers of Akola:

• The farmers in Akola planted a herbicide-tolerant variety of Bt cotton. This variety (HtBt) involves the addition of another gene, ‘Cp4-Epsps’ from another soil bacterium, Agrobacterium tumefaciens. It is not cleared by GEAC.
• The farmers claim that the HtBt variety can withstand the spray of glyphosate, a herbicide that is used to remove weeds, and thus it substantially saves them de-weeding costs.
• Farmers spend around Rs 3,000-5,000 per acre for de-weeding. Along with the uncertainty in finding labour, de-weeding threatens economic viability of their crops.

Concerns:

• Genetic changes made in a plant can make it unsafe for consumption, have adverse impacts on human or animal health, or introduce problems in the soil or neighbouring crops. There is an elaborate process of tests and field trials to be followed. Critics of GM technology argue that some traits of genes start expressing themselves only after several generations, and thus one can never be sure about their safety.
