2. Development of Roundup Quantity in RR Maize (I)
• Base assumptions for modeling*
– EU 27 glyphosate total market size is hard to determine
– Glyphosate use in EU 27 continues to slowly increase due to
discontinuation of other active ingredients
– EU 27 planting approval for RR maize is granted in 2011
– RR trait adoption by EU 27 farmers (including stacks) till 2020 will
be max. 50 % of EU hybrid corn market
– max. registered Roundup rate in RR maize is 6 l/ha (2160 g ae) per
cropping season, average total use in RR maize will be 4.5 l (1620
g ae)
– Roundup use in RR maize replaces 10 % of glyphosate applications
in the crop rotation
* As for all models, this summary is based on estimates, which may or may not reflect the real future situation

Based on the model, even at 50 % trait penetration in 2020, only 22 % of total glyphosate is used in RR maize
