Room (1979) had recognised that a hand-held computer-compatible device for recording data in the field would increase the value of SERATAC. The idea was revisited twice daring the SERATAC era. Final development of a product was delayed to lack of resources, and because the devices were cumbersome, expensive, task-specific and individually soon obsolete, while the software was device-specific and difficult to program (Hearn and Bange 2002). Advancements in computer technology over the past few years, with strong support from industry have enabled the original vision to become reality with the release of the first version of CottonLOGIC for Palm OS@ Handhelds. It has been developed by the CSRO/Cotton CRC cotton management support systems team at Narrabri, with the help of an in-field evaluation team, comprising of cotton pest managers from various regions. This paper presents details of the operation of CottonLOGIC for Palm OS handheld systems, and discusses issues resulting from field and independent evaluation.
