Disease incidence increasing in GM cotton in Oz (19/4/2007)

GM WATCH comment: Yet another example of farm management issues supposedly simplified by GM crops becoming ever more complex.

EXTRACTS: In central Queensland, it has been found that CBT is increasing and is most obvious in fields where Roundup Ready cotton had been planted...

The CRC reports that volunteer cotton can cause problems for resistance management of Bt cotton, reduce seed purity and act as early hosts for insect pest.

It also provides a conduit for carry over of harmful plant pathogens into the next season.

In the past, the broad spectrum herbicide glyphosate was commonly used to control volunteer cotton seedlings but this is not effective on Roundup Ready cotton.
