It is now estimated that in the period from 1996,when the GMO crops were introduced,to 2011,an additional 404 million pounds of chemical pesticides were applied to US fields,amounting to a 7 per cent increase overall.
In the meantime, companies such as Syngenta and AMVAC Chemical, which produce soil insecticides for corn, have reported increases in sales of 50 to 100 per cent over the past two years.
Which is larger, 7 percent over 15 years or 50 percent over 2 years?
