Farmers in the USA are undiminished in their reliance on green gene technology. In the case of maize, soybean and cotton, 88 per cent of seeds planted in the USA in 2009 were genetically modified and represent an increase of three per cent in comparison to the previous year. The proportion of GM varieties for maize and cotton has risen once more but for soybean has sunken slightly to 91 per cent. The field area for GM sugar beet has increased approximately by a third in one year. In total field area with respect to the previous year, change may hardly be found, although fields sown with soybean rose to a record level of 31.4 million hectare, a slight rise in comparison with 2008 (30.1 million hectare). Conversely, the field area of 35.2 million hectare for maize remained almost unchanged in comparison with that of 2008 and still lies 7 per cent under that of 2007. In the case of cotton, changes hardly could be found in comparison with the previous year and, with 3.66 million hectare, the total field area for this variety lies slightly under that of 2008 (3.7 million hectare). In the USA in 2009, maize, soybean and cotton were cultivated on a total of 70 million hectare – 61.7 million hectare of these with GM varieties.
GM cotton: fewer fields In the case of cotton, the proportion of GM varieties increased slightly from 86 to 88 per cent. In this case, farmers also bought primarily varieties with combined insect resistance and herbicide tolerance (‘stacked genes’, from 45 to 48 per cent). The field area of GM cotton remained unchanged in 2009 at 3.2 million hectare. On a smaller scale, GM rapeseed and GM squash are grown on the continental USA and GM papaya on Hawaii. The figures cited are taken from the official agricultural statistics of the United States Department of Agriculture (USDA). They are compiled by the National Agricultural Statistics Service (NASS) and are based on the assessment of seed sales and of representative polls of farmers. The report with up-to-date cultivation statistics for current growth seasons appears annually at the end of July. Field areas for genetically modified soybean, maize and cotton varieties are indicated therein.
