TABLE 4.

Other GM HT crops summary of active ingredient usage and associated EIQ changes 1996–2013

Country Change in active ingredient use (million kg) % change in amount of active ingredient used % change in EIQ indicator
GM HT canola      
US −2.2 −29.9 −42.7
Canada −15.8 −17.9 −29.7
Australia −0.4 −2.3 −1.8
Aggregate impact: all countries −18.4 −16.5 27.9
GM HT sugar beet      
US and Canada +1.7 +31.2 −0.8

Note:

1. Negative sign = reduction in usage or EIQ, positive sign = increase in usage or EIQ value.

2. In Australia, one of the most popular type of production has been canola tolerant to the triazine group of herbicides (tolerance derived from non GM techniques). It is relative to this form of canola that the main farm income benefits of GM HT (to glyphosate) canola has occurred.

3. InVigor’ hybrid vigour canola (tolerant to the herbicide glufosinate) is higher yielding than conventional or other GM HT canola and derives this additional vigour from GM techniques.

4. GM HT alfalfa is also grown in the US. The changes in herbicide use and associated environmental impacts from use of this technology is not included due to a lack of available data on herbicide use in alfalfa.
