The weed spectrum of many areas in the Australian cotton industry is not well documented. in addition, there is very little information known about the weed species present in the Hillston area and which of these weeds will present a problem to the expansion of cotton growing in the area. To address some of these issues, a weed survey was undertaken on three farms in the Hillston area on November 21 and 22 - 2001, just prior to first cultivation of many of the fields. The fields surveyed covered a range of production systems including conventional cotton, Roundup Ready cotton on two metre beds, twin row conventional cotton planted on two metre beds, and Roundup Ready' cotton planted on UNR beds. Assessments were conducted along transects from the tail ditch to the head ditch and weeds assessed in both rows and furrows on a number of transects (the actual number was dependent on the field size).
