TABLE 2.
Country | Change in active ingredient use (million kg) | % change in amount of active ingredient used | % change in EIQ indicator |
---|---|---|---|
US | −204.4 | −9.9 | −13.7 |
Canada | −10.2 | −17.3 | −20.6 |
Argentina | −0.6 | −0.6 | −6.7 |
South Africa | −2.7 | −2.5 | −6.8 |
Brazil | −8.1 | −2.6 | −8.9 |
Uruguay | −0.02 | −0.2 | −9.3 |
Aggregate impact: all countries | −226.3 | −8.4 | −12.7 |
Notes:
1. Negative sign = reduction in usage or EIQ improvement. Positive sign = increase in usage or worse EIQ value
2. Other countries using GM HT maize – Colombia, Paraguay and the Philippines, not included due to lack of data. Also, hand weeding is likely to be an important form of weed control in the Philippines suggesting any reduction in herbicide use with GM HT maize has been limited
