Bt

Who used an additional 144 million kg of herbicides in the last 13 years?

A new study by Charles Benbrook shows that farmers in the US from 1996 to 2008 used 144 million kg (318 million pounds) of herbicides more then compared to conventional agriculture.
This is mainly caused by the development of herbicide resistant weeds and due to the fact that herbicide applications in conventional agriculture continuously decreased in the same period.

Gift im Gen-Mais

[img_assist|nid=174|title=|desc=|link=none|align=right|width=100|height=43]Im folgenden Report werden einige mögliche Auswirkungen des Bt-Maises auf die Umwelt dargestellt. Selbst nach mehr als 10 Jahren kommerziellen Anbaus von Bt-Mais gibt es nur wenige Studien zur Risikoabschätzung. Zugleich werfen die meisten dieser Studien mehr neue Fragen auf, als sie beantworten.

Bt Toxin in GM maize

[img_assist|nid=174|title=|desc=|link=none|align=right|width=100|height=43]The report presented here shows the many ways Bt maize impacts the environment. Even after more then a decade of commercial growing of Bt maize crops, the risk assessment studies are still few and most of them tend to raise more open questions than solving concerns.
