What is Bollgard 1 and Bollgard 2?
Bollgard I Bt cotton (single-gene technology) is India’s first biotech crop technology approved for commercialization in India in 2002, followed by Bollgard II – double-gene technology in mid-2006, by the Genetic Engineering Approval Committee (GEAC), the Indian regulatory body for biotech crops.
How does Bollgard 3 work?
Bollgard 3 contains three proteins, Cry1Ac, Cry2AB and Vip3A, each ‘killing’ larvae in a different way. Having three different active proteins increases the sustainability of the technology as it is difficult for helicoverpa to develop resistance to more than one of the Bt Proteins.
What is Bollgard II?
Bollgard® & Bollgard®II Bollgard® II technology contains a superior double-gene technology – Cry1Ac and Cry 2Ab which provides protection against bollworms and Spodoptera caterpillar, leading to better boll retention, maximum yield, lower pesticides costs, and protection against insect resistance.

What is Bt cotton and Bt brinjal?
Bt Brinjal is a transgenic brinjal created by inserting a gene cry1Ac from the soil bacterium Bacillus thuringiensis into Brinjal. This genetically modified brinjal gives resistance against insects such as the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis).
What is BT Brinjal Upsc?
Which type of cotton seed is best?
