We have conducted experiments on this problem for five years, and summaries of this work have been reported at earlier cotton conferences (1994 and 1996) and in the CSD premature senescence grower information leaflet.

(I) To continue and develop the work begun in UsQ6C which focuses on residue handling in back to back cotton and rotation crops while optimising the control of diapausing heliothis pupae.

Good average irrigated yields have been achieved on the Darling Downs by most growers this season while dryland crops on average did not fare so well due to the unseasonal hot dry conditions.

This paper describes the results of a two season pilot study assessing the utility of Landsat TM satellite data for identifying and mapping land cover in jinxed agricultural regions.
