GM crops drive 9% fall in global ai use
The use of genetically modified crops continues to drive a reduction in insecticide and herbicide use, finds the latest in a series of annual reports from UK consultancy PG Economics. It attributes an 8.7% or 392,730 tonnes drop in the amount of active ingredients used globally between 1996 and 2009 to adoption of GM crops. Most of this was due to a fall in herbicide ais, down 203,610 tonnes, with insecticides down 189,120 tonnes. The figures continue the downward trend shown in previous years ( Agrow No 581, p 13). The report also points out that the environmental impact of herbicides used on GM crops compared with their conventional counterparts was reduced across the board, mainly due to the use of more “environmentally benign” herbicides.
