The cotton industry in Australia continues to be Tenant on insecticide and fertiliser inputs to maintain yields. Over the past decade the off farm movement of these pollutants in runoff water has created a number of environmental issues of concern for the industry (Edge; 1996). In particular, pesticide can be transported off farm in solution or attached to suspended sediment, which are a major factor in pesticide contamination of rivers particularly as storm runoff (Schoefield et al1998). As part of a major R&D program undertaken by the cotton industry, the transport mechanisms and fate of cotton pesticides and nutrients were investigated to address the contamination issue. Key findings from the work identified the high-risk period as early season and highlighted the importance of storms and sediment in moving pesticides off-site and the importance of ground cover in reducing movernent (Simpson et al 1996 and Silburn et al 1996). At the completion of the program, the cotton industry had a much better understanding of the process of pollutant movement from farm to river. However, few proven practical techniques were available to growers to reduce the risk of off-site movement of pollutants in runoff.
