Black root rot, caused by a soilborne fungus, was first observed in Australian cotton in 1989. The disease has developed rapidly since then and now occurs in most of the cotton production area in NSW and Queensland.

The aims of the project were: (1) Use composted cotton gin trash and pelletised cotton gin trash to

monitor soil response and soil nutrition benefits; (2) Establish experimental woodlots of

To help understand the underlying basis of the resistance to pirimicarb, and hence improve the chance of effective management, Dr Robin Gunning and Dr Graham Moores (Rothamstead, UK) did a preliminary screen on resist

Outcomes

Key factors in managing transgenic Bt cottons for the future are to have an effective resistance management strategy. An essential component of any such strategy is to establish a resistance monitoring program.
