bt cotton

Catalogue: Broadacre Field Crops DAFF QLD
Insect-resistant cotton is often called 'Bt cotton'... The Australian cotton industry was well aware that the adoption of Helicoverpa -resistant varieties that would be expressing the Bt toxin throughout the length of the cotton season posed a considerable resistance risk... A comprehensive resistance management package has been negotiated between industry, regulators and the owners of the GM technology to ensure that growing practices have been adopted to protect the longevity of the Bt toxins used in the current GM cotton varieties...

Landscapes in the Darling Downs, QLD, were mapped and characterized for their pest suppressive potential - eg. the ability for localized reduction in pest populations in grains due to the amount and location of Bt cotton in the landscape... Once mapped, 16 crops (8 sorghum and 8 cotton) in each of three landscapes were selected for fortnightly sampling of Helicoverpa moths and eggs... Data analysis is on-going, but to date results support those found in an earlier study, which is that there are regional differences in Helicoverpa pressure and this is most likely due to different composition of crops across a landscape...
