Advanced breeding selections initially selected at Biloela outyielded CSIRO selections initially selected at Narrabri. In contrast, the Biloela selections were low yielders when tested in New South Wales (NSW).

Three methods of determining levels of resistance in H.armigera were evaluated. These included: (i) a standard glass vial test (ii) a tropical application (iii) a leaf disc test

The objective for this project was to erect and operate a fibreglass greenhouse at Narrabri.

The overall aim of the soils research program based at Trangie has been to develop management strategies that maximise the profitability of irrigated cropping by: (i) correcting yield limiting soil physical problems;

The main aim of this trip was to report to the international scientific community on the progress of the Insecticide Resistance Management Strategy that has been implemented in Australia to contain pyrethroid and endo

Pest management is only one link in the cotton management chain. To produce an early crop it is essential that all links in that chain be securely welded together.

BACILLUS THURINGIENSIS use as an insecticide for 25 years despite formidable competition from conventional insecticides is largely due to its safety and compatibility.

One such form is biological control, which relies on the use of natural pathogens and parasites to control the pest species.

Cotton growers commonly apply nitrogen (N) fertilizer at rates of between 100 and 200 kg N/ha, yet the cotton plants seldom recover more than 40% of the applied N, and often much less.

The aim of the present work is to assess the usefulness of pteridines in determining the age of adults of P. scutigera.

The CRC contracted Queensland Cotton and Siratac Ltd. to conduct a survey on the transfer of research information into the cotton industry.

To understand, and predict, Heliothis dynamics on cotton, along with changes in resistance levels, we must understand their dynamics on other hosts and the patterns of movement from these to cotton.

SIRATAC users have the option early in the season of using standard thresholds or dynamic thresholds which vary between the standard level and an upper limit.

Determination of the petiole nitrate nitrogen concentration (PNN) in the youngest fully expanded leaf (YFEL) of cotton is a useful indicator of plant nitrogen status.

The Siratac system when it was originally conceived had no database system included in the workings of the system.

Well to satisfy everyones's curiosity, r will answer the question straight away. Yes, we can survive resistance! However, in answering it, I shall put another, perhaps even more thought provoking than the first.
