A technique to identify the host crop of Heliothis moths by analysis of elemental content has been progressively developed over several seasons (CRC Project CS13L, Fin 1986).

The cotton industry is one of the most technologically advanced agricultural industries in Australia.

The aims of the trial were: 1. To determine whether mating of H. armigera could be disrupted in cotton by mass release of pheromones; 2.

A survey form asking the cost of weed control, the major weed problems and the herbicides used was sent to fifty two cotton growers from the seven major cotton areas of New South Wales.

The development of population dynamics models of heliothis populations in multi cropping systems required information on reproductive development, longevity and lifetime fecundity of adult female Heliothis in order to

A technique to identify the host crop of Heliothis moths by analysis of elemental content has been progressively developed over several seasons(CRC Project CS13L, Fin 1986).

The initial phase of the project was devoted to the selection and testing of analytical techniques for assessing total nitrogen and leaching losses, and gaseous losses of nitrogen by ammonia volatilization and denitri

The objective of this project was to look at economic optimisation within the SIRATAC framework.

This project was initiated under the name "CS66L - SIRATAC Plus configuration and testing". However, the Siratac Plus project proved a failure and all development was abandoned in 1990.

I was invited to speak at the conference to give a paper at one of the sessions.

During August 1990, in company with Dr Norm Thomson, Mr Reid visited a number of research institution and companies form California to Mississippi.

A survey form asking the cost of weed control, the major weed problems and the herbicides used was sent to fifty two cotton growers from the seven major cotton areas of New South Wales.

The first Queensland soil management training workshop was held in July 1991 at Dalby. Funding came from the Cotton Research and Development Corporation and the National Soil Conservation Program.

The main aim of this project was to develop a low-cost multispectral airborne video imaging system (referred to as MAVIS) for detecting and monitoring spatial and temporal variations in the vigour of irrigated cotton

Aims: (i) to quantify the contribution of alternative host crops to the dynamics of Heliothis on cotton using an elemental analysis technique developed in a previous project.

To quantify movement of Heliothis adults Into cotton crops from local and distant source regions.

Aims 1. Promote awareness of the importance of soil management 2. Collate existing research results and practical knowledge of the management of irrigated cracking clays. 3.

This project was concerned with the transfer of cotton fibre testing from the Division of Wool Research, Geelong Victoria to the Cotton Research Unit at Narrabri Agricultural Research Station (NARS).
