Write a short note on Bt cotton. A simple answer would help!!!!
Bt cotton is genetically modified form of cotton which is resistant to the common pests of cotton like moths, beetles, flies. Bt cotton contains the gene for Bt toxin which is a toxin produced by the bacteria Bacillus thuringiensis. Hence, Bt cotton produces this toxin which is harmful to the pest but not harmful for other organisms. On consumption of the plant parts, the insects ingest toxins which create pores in the stomach of insects resulting in death.
Therefore, Bt cotton is a plant which produces natural pesticides and helps in reduction in the use of chemical pesticides in cotton fields.
