As the first presentation on this topic I would like to very briefly outline the major advantages of producing an early crop.

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

It was once a commonly held belief in central Queensland that, because the potential cotton growing season was a long one, earliness was not an important management consideration.

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

To the question "Can nutrition affect earliness?" the answer must be a definite Wes". Further, it will be just as important a factor as irrigation or pest management.

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

From before the first seed is planted, everything that 1s done, 1.e. selection of seed variety, to all cultural practices and 1nsect control must have one aim and that is earliness.

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.

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.

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.

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

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

You are all aware that currently there are three varieties available commercially: Siokra 1-2, Sicala 3-1 and DP90 (Deltapine - Acala) .

Seedling diseases include seed rots, pre and post emergent damping 9ff and root pruning. Numerous fungi can be responsible although Rhizoctonia sp., Pythiwn spp. and Fusarium spp. are the most important.

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.

This Overview has been compiled after talking with a limited number of growers from most districts, and as could be expected there were some opposite opinions expressed.

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.
