Small palaeochannels located in irrigated cotton fields have been identified as areas of potential high deep drainage (Triantafilis et al. 2003).

Bioremediation can be defined as any process where biological agents provide a practical solution to the unwanted presence of a chemical substance.

For season 2004-2005, sixty-one percent of cotton aphid populations were Pirimor resistant but Intruder, Actara, Thiodan and Pegasus susceptible. Two-spotted mite was Agrimec, Comite and Pegasus susceptible.

The cost-benefit analysis of 43 fields of cotton defoliated using at least one pass with variable rate chemical application, showed significant benefits for the farmers involved.

Achievable paddock yields now frequently overreach the science and yields upon which our current crop nutrition practices are based.
