While a number of transgenic crops proposed for introduction into Australia have transgenic herbicide tolerance as one trait, not all herbicide-tolerant crop varieties to be introduced into the Australian farming system were produced through the use of genetic engineering techniques. All herbicide-tolerant crop varieties, regardless of how they were produced, will have an impact on the management of existing herbicide-resistant weed populations and on the potential for further resistance evolution in weeds. The herbicide tolerances most likely to be introduced and the implications for resistance management are discussed.
