Cotton plants expressing the CrylAc toxin from Bt are near to commercial release.

A large collection of microorganisms with over 2000 isolates has been established at the Australian Cotton Research Institute for the purpose of identifying potential bio-control agents and developing biological contr

Supplementary funding was provided by the CRDC allowing three personnel ($1750 each, $5,250 total) from the pesticide chemistry group to attend the 8th International Congress on Pesticide Chemistry, held in Washington

Nutgrass control was examined in field and glasshouse studies. A nutgrass control strategy was developed based on Zoliar and in-crop Roundup, and infallow, cultivation in dry conditions and Roundup in wet conditions.

OBJECTIVES: 1. To study sampling and control practices for mirlds in irrigated and dryland cotton.

Modern molecular genetic techniques are used to examine Helicove1pa armigera for variation amongst individuals from different geographical locations around Australia.

In July 1994 the International Society of Soil Science held its 15th Congress in Acapulco, Mexico. Approximately 1800 ISSS members from almost 90 nations attended.

This report arises from a scoping brief presented to the author on 19th May 1995.

Frontiers of Population Ecology Meeting program and abstracts

In March 1995 I attended two Keystone Symposia, "Frontiers of Plant Morphogenesis" and "Signal Transduction in Plants", held concurrently at Hilton Head Island, South Carolina, U.S.A.

The cotton plant has two main sets of traits that contribute to its resistance to pests: (1) chemical (e.g. gossypol) and morphological defences (e.g. okra-leaf) and (2) compensatory mechanisms for regrowth (e.g.

Cotton fibres are differentiated from single ovule epidermal cells and grow synchronously, initiating at about the time of anthesis.

Annual Report 1994-1995

This report summarises the findings from the CRDC funded project "Managing soils to avoid compaction problems in cotton growing". The project ran from 1989/90 to 1991192.

Project Objectives: Part A: (i) To study the effect of wet/dry cycles with drying by evaporation alone in ameliorating degraded furrows in retained hill cotton (at the Fressor site).

A growth disorder of cotton ( Gossypium hirsutum) occurs in irrigated cracking clay soils in cotton growing regions of northern New South Wales.

Vertosols are the main soil type on which cotton is grown in Australia. Eighty percent of irrigated cotton is grown in retained hill.

OBJECTIVES: 1. To study sampling and control practices for mirlds in irrigated and dryland cotton.
