In surface irrigation systems we use beds rather than growing thee crop on the flat for several reasons.

During the 1991-92 season, a 1 ha block of unsprayed raingrown cotton near Dalby was sampled for parasite activity in heliothis larvae.

Encouraged by a trial 1/2 acre result of 2.8 bales per acre from the 1990 cotton pick, Tandou has grown 70 acres in 1991 and 850 acres in 1992 installing one roller gin to process the 1991 crop and expanding the gin t

Recent research has indicated that two species of native egg parasitoids, Trichogramma (Trichogrammanza) carverae Oatman and Pinto and Trichogrammatoidea bactrae Nagaraja, have potential as biological control agents o

This paper presents techniques used for rearing egg parasitoids on AGM eggs in an experimental facility at the QDPI Division of Plant Protection entomology laboratories in Toowoomba.

During the 1990-91 and 1991-92 seasons planting date experiments were carried out at Narrabri Agricultural Research Station using a range of cotton varieties.

This paper provides an overview of the Cotton Research and Development Corporation project DDI lL, which is in its final year at the University of Southern Queensland.

In July 1992 the 9th International Working Meeting on Soil Micromorphology was held in, Townsville, Queensland. It was sponsored by Sub-Commission B of the International, Society of Soil Science.

Funding from the CRDC and NSW Agriculture allowed two District Agronomists from major cotton producing areas to attend the International Pesticide Application Technology Residential Course at the Gatton campus of the

The potential of leading tines to produce a finer tilth and allow operations at moisture contents \ Q higher than previously possible without producing smearing could possibly be exploited in implements for the renova

The overall aim is to house current and future staff for our expanded research projects in the next decade.

Objectives of Travel. (i) to attend the XIX International Congress of Entomology, Beijing, China.

The main aim of this trip was to accept the invitation of the Organiser of the Symposium on "The Realities of Insecticide Resistance Management" (Dr George Georghiou) to present a paper on "Nine Years o

The Project The Galathera syndrome affects cotton growing in the Namoi Valley, north-western New South Wales.

Techniques for mass rearing egg parasites on eggs of the factitious host Sitotroga cerealella (Angoumois Grain Moth - AGM) were further developed and refined.

The aim of the project was to produce more virulent strains of a naturally occurlng entomopathogenlc nuclear polyhedrosls virus of Heliothis species.

To develop, validate and implement a regional model of Helicoverpa population dynamics which considers the abundance, movement, oviposition, development and mortality of H.armigera and H.punctigera on all major hosts

Disease Surveys. Commercial cotton (Gossypium hirsutum L.) fields in the Mcintyre, Gwydir, Namol and Macquarie valleys of New South Wales were inspected in November and March each season.

This is an on-going project of breeding cottons adapted to Australian growing conditions, diseases and pests and markets.
