Quantitative Bt ELISA assays have only recently become available as a research

tool. This research will not only assist cotton breeders in identifying lines which possess

The use of plant growth regulators has been a common practice in the production of Australian cotton for at least two decades.

Lablab was grown in two field experiments at Narrabri, NSW.

We have carried out one season of experiments on plant growth regulators that have not been used commercially in the Australian industry before (Glycinebetaine, Gibberellic acid and PGR TV) and compared these to Pix.

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.
