Organic Cotton is an alternative to Bt Cotton. What is Bt Cotton? Bt cotton is a genetically modified variety of cotton producing an insecticide. It is produced by Monsanto. It is supplied in India's Maharashtra state by the agri-biotechnology company, Mahyco, as the distributor. The bacterium Bacillus thuringiensis (Bt) is a family of over 200 different proteins which naturally produce chemicals harmful to selective insects, most notably the larvae of moths and butterflies, beetles, cotton bollworms and flies. IT IS HARMFUL (Deadly) to Butterflies. The gene coding for Bt toxin has been inserted into cotton, causing cotton to produce this natural insecticide in its tissues. In many regions, the main pests in commercial cotton are lepidopteran larvae, which are killed by the Bt protein in the transgenic cotton they eat. This eliminates the need to use large amounts of broad-spectrum insecticides to kill lepidopteran pests (some of which have developed pyrethroid resistance). ...A 2006 study done by Cornell researchers, the Center for Chinese Agricultural Policy and the Chinese Academy of Science on Bt cotton farming in China found that after seven years these secondary pests that were normally controlled by pesticide had increased, necessitating the use of pesticides at similar levels to non-Bt cotton and causing less profit for farmers because of the extra expense of GM seeds...
