Explanation

Bt-brinjal is a genetically modified variety of eggplant developed to provide resistance against the Brinjal Fruit and Shoot Borer (EFSB), a highly destructive pest. The technology involves inserting the cry1Ac gene from the soil bacterium Bacillus thuringiensis (Bt) into the plant's genome. This gene enables the plant to produce insecticidal crystal proteins that are toxic to lepidopteran insects like the EFSB larvae. While traditional chemical sprays are often ineffective once larvae bore into the fruit, Bt-brinjal provides built-in protection, significantly reducing the need for synthetic pesticides [3]. Although it has been commercially cultivated in Bangladesh since 2013 with success, India has maintained a moratorium on its commercial release since 2010 due to environmental and health concerns raised by civil society [2]. The primary objective remains pest resistance rather than improving nutrition, shelf-life, or drought tolerance.

What are the reasons for the people’s resistance to the introduction of Bt brinjal in India? 1. Bt brinjal has been created by inserting a gene from a soil fungus into its genome. 2. The seeds of Bt brinjal are terminator seeds and therefore, the farmers have to buy the seeds before every season from the seed companies. 3. There is an apprehension that the consumption of Bt brinjal may have adverse impact on health. 4.
