The objective of this project was to modify the weather station at our Breeza Australian Cotton Cultivar site to enable the use of the telephone system and the SIRATAC computer to collect the data.

Installation of a Halon gas fire suppression facility has been completed at a total cost of $12,970* including the linking of the warning system to the building's fire warning system.

The application of the chemical technique developed in DAQ27L in determining the age of field collected adults of Pectinophora scutigera (pinkspotted bollworm).

Heliothis armigera and H. punctigera are serious pests of cotton in Australia. Control of Heliothis is currently dependent on insecticides.

Despite it's status as a pest of cotton (Gossypium hirsutum L.) in Central Queensland, the biology and ecology of the pink-spotted bollworm, Pectinophora scutigera (Holdaway), is poorly understood.

The aims of the project were: * to test various versions of SIRATAC on a commercial scale. * to provide a database of the response of cotton to damage.

objectives of the present work are the identification of the sex pheromones of Crocidosema plebejana and Pectinophora scutigera and the testing of synthetic candidate mixtures as attractants in monitor traps in the fi

Project objectives To determine the nature and extent of migratory flight in Heliothis Armigera and punctigera and to estimate the significance of migration in the formation of outbreaks and in the spread of insectici

Heliothis armigera and H. punctigera are serious pests of cotton in Australia. Control of Heliothis is currently dependent on insecticides.

Objectives o Determine optimum nitrogen rates for cotton under a range of conditions. o Determine the best time to apply this nitrogen.

The aims of the project are to provide a basis for sound irrigation management of cotton through studies of: � (i) Crop response to a range of irrigation management options in terms of crop irrigation efficiency (yiel

Changes in Helicoverpa populations in non cropping areas

Project aims: (i) to investigate the spatial and temporal patterns of Heliothis adult and larval abundance, mortality and host use by each species and their dispersal from other crops into cotton.

This project started in 1981 funded by ACGRA. CRC assumed funding until the project terminated in 1986.

Large scale trials of SIRA TAC comparing standard and dynamic thresholds were done for three years on commercial farms along the length of the Namoi valley.
