I am delighted to have been asked to speak on this vital topic.

The wild ancestors of cotton are found in the arid regions of the world.

Today's rising environmental consciousness is having a real influence on consumers' decision-making about their product purchases.

Rainfed cotton has been grown in Central Queensland since the 1920's but the total area has fluctuated in response to variable seasonal conditions as well as changing prices and market trends for cropping options

The affects of hail on the growing cotton crop will be well known to virtually all growers, as will the method of assessment which Is used in conjunction with the Australian Cotton Industry's Hail Insurance Schem

In dealing with nitrogen and Pix, points to put the issues in context are that nitrogen is the most important because it can increase yield by much more than a growth regulator such as Pix can.

The Australian Cotton Foundation (ACF) was established in 1973 to promote cotton and the Australian industry. It was also seen as the appropriate body for internal education and industry representation.

The objective of the experiments reported in this paper is to determine the fate of fertilizer nitrogen applied to the grey clays in the Namoi Valley.

To better understand the new Research and Development Corporation I feel it would be appropriate to review cotton research historical I y, as background lo the soon to be created corporation.

Waterlogging can affect both the availability of micronutrients in the soil and the plant's ability to absorb nutrients from the soil.

The title of this discussion has a rather ominous ring to it as far as I am concerned.

SOILpak is a soil management manual for cotton growing on cracking clays. It leads you through the decision-making process to a number of options. The manual presents options rather than hard-and-fast rules.

Ecological genetics is the study of genetic changes and how these are influenced by the biological parameters of a species.

The aim of the Heliothis identification project is to develop a simple kit that can be used by field workers to distinguish quickly and reliably between individual eggs and small larvae of Heliothis armigera and H.

Over the last two growing seasons, sampling studies have been conducted to compare the distribution and abundance of Heliothis on different cotton varieties and to test the validity of the SIRA TAC equations which exp

The potential for extensive adult movements is one of the key factors contributing to the success of Heliothis spp. as pests (Farrow & Daly 1987, Fitt 1989).

Information about the frequency and intensity of immigration and emigration movements is essential for forecasting Heliothis infestation levels in crops, and thus for developing more efficient strategies for managing

The pattern of flight activity within or between habitats or crops is dependent upon the distribution of those habitats/crops in both space and time.

Heliothis spp. are clearly the major pests of Australian cotton and consequently there has been considerable research on their biology, ecology and control (Zalucki et al 1986).

An important question is the area of origin of these spring immigrants. Over the last 3 years, we have been investigating the ecology of Heliothis spp. in inland Australia (Gregg et al. 1987, 1989).
