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.

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

This grant provides foods for the annual maintenance contract for the Vax 4000 computer system at NARS. The system has been installed and operational since October 5, 1990.

Aims: 1 * Develop a simple mite management package using data collected relating mite infestations to cotton yield loss. * Complete development and validation of functional sampling procedures.

A self propelled high powered; high clearance insecticide sprayer is now available to cotton growers. As with all products development continues.

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.

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

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.

In June 1993, Mr Neville Gould, Team Leader, Agricultural Engineering, NSW Agriculture, Trangie travelled to the USA for 30 days to investigate for the Australian cotton industry the issues of anhydrous ammonia applic

In 1990, a Cotton Research and Development Corporation funded project was begun, in cooperation with the Industry Hail Scheme Insurers, to evaluate the growth response after hail damage, of cotton varieties currently

The objectives of this project were to evaluate the potential of larval parasitoids, principally Microplitis, for use in biological control programs against Helicoverpa spp.

OBJECTIVES 1. To establish Helicoverpa species composition in the Macquarie Valley and to relate the data to that from other cotton growing areas in NSW and Queensland. 2.

An insecticide resistance management (IRM) strategy was introduced into the summer rainfall cropping areas of eastern Australia in the 1983/84 season.

Project Objective: A new project with the objectives of: * to supply equipment to accurately weigh cotton from field trips.

A workshop convened by the Cooperative Research Centre for Tropical Pest Management at Narrabri on 7-8 December 1992 examined the feasibility, benefits, and funding implications of providing an operational forecasting

Funded by the Cotton Research and Development Corporation under the general topic "Physical and Chemical Studies of Cotton Fibre Maturity", the project has focused on searching for links between the morpholo

The aims of this project, viz: (i) To purchase an item of equipment necessary for the extraction and analyses of allelochemicals present in cotton varieties under evaluation for their rcsi~tance to insect pests (ii) T
