Herbicide-resistant rape spreads its manipulation by Jurgen
Genetically engineered rape plants on a test field in Gehrden near Hanover
have passed on their herbicide-resistance gene to ordinary rape growing in
the area. The Niedersachsen Ministry for Ecology (NLV) has been able to
show that normal rape situated at a distance of 200 metres from the test
field of the Hoechst/Schering subsidiary AgroEvo has been transformed into
transgenic, herbicide-resistant rape.
The Niedersachsen Minister of the Environment, Monika Griefahn, said that
the NLV research in Gehrden confirmed her worst fears. "Once the
manipulated genes are released into the surroundings, there is no way to
contain them," said Griefahn yesterday in Hanover. Bees and wind spread the
pollen of genetically engineered plants just as they do with other plants,
and in this case they also spread the artificial genes.
The open-air field trial to grow the genetically modified rape, which is
resistant to the herbicide Basta [glufosinate ammonium], was authorised in
1995 by the Robert Koch Institute in Berlin, in the face of opposition from
Griefahn. AgroEvo merely had to provide an eight-metre safety border around
the test field.
Niedersachsen financed its own research programme, parallel to the open-air
field trial, at a cost of DM450,000. Within a radius of 1,000 metres around
the test field, the NLV indexed plants and collected hundreds of thousands
of seeds from wild plants and normal rape growing in the area.
The NLV has so far tested only the rape seed it has collected, for the
Basta resistant gene. The seeds were fed a solution containing the Basta
herbicide. Seeds that grew into plants in spite of the Basta were then
tested for the herbicide-resistant gene. Environment Minister Griefahn is
concerned that further tests will show that the resistance gene has been
carried over into wild plants as well. Most likely this would occur with
plants that are related to rape, such as mustard or wild radish. A transfer
of resistant genes to these type of plants would cast doubt on the whole
concept of Total Herbicide, by which the seed of the genetically modified
plant is sold together with the corresponding herbicide. Wild plants that
had absorbed the resistance gene from the genetic rape would then thrive
magnificently as weeds and increase, in spite of the use of
Following the first NLV findings, it is clear for Monika Griefahn "that in
the neighbourhood of transgenic fields cultivated plants can also become
transgenic". This would harm also those farmers who declined to use
genetically modified crops. They would no longer be able to guarantee to
the consumers that their products are not genetically modified.
