Main reason behind B.t Brinjal controversy

To know the main reasons why the B.t brinjal is a controversy we should first know about B.t cotton.
Bt cotton was approved for release in India by the Ministry of Environment and Forest, Government of India, on March 26, 2002. Over the last seven years, it has revolutionized cotton production in the country, doubling it from 13.6 million bales in 2002-03 to 31.5 million bales in 2007-08. The yield per hectare, which was hovering around 300 kg per hectare for more than a decade until 2002, touched an all time high figure of 560 kg per hectare in 2007-08. In fact, India emerged as the world’s second largest cotton producer in 2006-07, edging past the US, which held the second rank until then.
But recently a new report published by scientists at the Central Institute for Cotton Research (CICR), Nagpur, in the 25 July issue of Current Science, validates many of the observations made by Gene Campaign during three years of field studies on Bt cotton cultivation. The study conducted at India’s premier cotton research institution gives the scientific reasons for the failure of the Monsanto Bt cotton varieties and shows that India’s Bt cotton technology itself is faulty and will fail to protect cotton farmers from the bollworm. The study recommends additional pesticide sprays since the Bt technology fails to provide adequate protection.
The study also showed that farmers who adopted Bt cotton had a net lower income than non-Bt cotton farmers. Seed dealers had promised farmers that they would get 12–15 quintals per acre when the actual yields were 3–5 quintals.

This is the reason why all the analysts are concerned about. If India imports this this technology it may be a success for a period of 4 to 5 years till the insects gain the resistance. But believe that it will be a disaster in future.
