The importance of Heliothis has grown with the advent of resistance in H.armigera to various pesticides.

We have conducted a series of experiments at Trangie, Warren, Narrabri and Moree to examine the use of shallow leading tines in conjunction with rippers. Ripper depths of 300, 450 and 600 mm have been investigated.

The companion project to SOILpak, "Soil management training for advisers to cotton growers" has made a good start in familiarising consultants and agronomists with structural recognition.

In the 1991/92 season we started observations in both sprayed and unsprayed plots of different cotton varieties to record the numbers of fruit lost during the season and to identify the causes of shedding.

Cotton growers began to realise in the late 1970's that compaction of clay soils may have been a cause of declining yields. Research over the last 10 years has confirmed those suspicions.

The reliance of the Australian cotton industry on insecticides for the control of insect pests represents a major economic and environmental concern. In the face of pesticide resistance in H.

This project was established to find a simple, repeatable and reliable technique or series of techniques for consultants, extension personnel and managers to use to assess soil structural conditions in the field.

A change of direction for entomoLOGIC and some improvements to hydroLOGIC will provide growers and consultants in the 1992/93 season with effective, low cost decision support systems for irrigation and pest management

The question is asked - Why grow Pima in A ustraha? There are different answers. The most obvious is the economic consideration, then there is the challenge of doing something new and different.

Nitrogen management plays a key role in cotton production. It is the nutrient required in greatest quantity by the crop and it is the nutrient most often deficient.

It has been 9 years now since the introduction of the Summer Crop Resistance Management Strategy in 1983/84 season.

I have been in Australia to attend 'the 1992 Australian Cotton Conference' in Qld and to visit the Cottonseed Mill of Cargill Oilseed at Narrabri , last August.

A Magellan Nav pro 5000 receiver and external antenna kit was bought and tested. The unit has recorded the locations of soil pit and disease sampling sites.

The project was intended to collect germplasm of two of the wild relatives of cotton, Gossypium australe and G. sturtianum from eastern Australia, and to initiate a seed bank of these species.,

This report presents the findings and recommendations arising from a review of dryland salinity R&D commissioned by a consortium of the three agencies responsible for most of the Commonwealth funding support for d

This report summarises the findings from the CRDC funded project "Managing soils to avoid compaction problems in cotton growing". The project ran from 1989/90 to 1991/92.
