"The revolutionary Bacillus thuringiensis (Bt) cotton crop in India has started losing steam steadily due to lack of innovation and diversified pest attacks emerging from frequent changes in climatic conditions.
As is evident from the data collated by the Cotton Advisory Board (CAB) under the Union Ministry of Textiles, cotton yield has started falling gradually after the four years of revolution between 2002 and 2006 when bollworm-resistant Bt cotton seed changed farmers’ economy. After that, however, farmers have witnessed a sustained decline in yield from a peak level of 554.39 kg per hectare (ha) in the cotton year 2006-07 (October – September) to an estimated 488.89 kg per ha in 2012-13."
