Objectives To enhance technology transfer between researchers, consultants and farmers and to develop approptiate commercial technology for farmer adoption.

Aims: (i) To evaluate the pest resistance of cotton cultivars bearing different combinations of morphological and allelochemical resistance factors in field experiments.

Objectives 1. To develop a method for the measurement of mass flow of anhydrous ammonia fluid. 2.

Growing other crops in rotation with cotton appears to offer the best prospect for long term viability of the cotton industry.

This Project was a preliminary study to develop an R&D program into CT based farming systems for the dryland cotton industry.

The Australlan Entomological Society Conference in Cairns from 3 to 8 July 19S3, was attended by Melina Miies (Department of Entomology, UQ).

The Cotton Research and Development Corporation Project US05C aims to provide techniques for the rapid assessment of rootzone salinity for cotton growing soil profiles of northern New South Wales and south-eastern Que

The objectives of this project were to sample Gossypium sturtianum (Sturt's Desert Rose) in the Flinders and Barrier Ranges and multiply the samples for research and conservation.

This project was initiated in 1991, following concern expressed by local cotton growers about suspected high insecticide resistance at St George.

During this trip I was able to liaise successfully with the following colleagues concerned with resistance and its management: Drs Rick Roush (Cornell), Alan Devonshire (Rothamsted), Chris Curtis (London School of Hyg

Aims: 1. To determine the rates, form and placement of fertiliser appropriate to alleviate potassium deficiency and premature senescence. 2.

The Second Canberra Bacillus thuringiensis Meeting was held in the Manning Clark lecture theatre complex at the Australian National University from 21st to 23rd September 1993.

In this and a related project funded by ARC, four fungal isolates of each of two common species were compared for their effect on plant growth.

Aim: To investigate the sensitivity or tolerance of Australian cotton varieties to levels of UV-B expected to exist in the foreseeable future

The spatial variation in crop yield, and the field-based factors that contribute to it, is developing as a subject of importance to both the farming and wider communities.

This project examined genetic variation in Helicoverpa populations using variation in mitochondrial DNA (mtDNA) and variation in quantitative traits, and was supported by ARC as well as CRDC.

Mr. Martin Dillon was not able to attend the congress, as it coincided with the birth of his son on 24 November 1993. However, Martin Dillon and Dr.

Annual Report 1993-1994

In September 1993 the Management Committee of the National Program for Irrigation R&D requested the authors to prepare a briefing paper on Technology Transfer.
