The aim of the project outlined here is to try and develop the SOLICON techniques that are already being used by soil researchers in order to find a practical technique available to cotton consultants or agronomists (

Agriculture is now recognised to be among the highest risk industry groups for occupational injury and disease.

Various parasitoids of heliothis have been considered in integrated pest management programs throughout the world.

One of the few aspects of our industry that is controllable is injury to people.

Having previously identified poor N recovery as largely a denitrification problem, research began to investigate means of reducing N loss.

In common with about 80% of all plants, cotton forms VAM (vesicular-arbuscular mycorrhizas). VAM are associations of soil-borne fungi with the roots of plants.

The HEAPS (HE.licoverpa d.rmigera and l!.imctigera Simulation) model embodies all of our current knowledge on the ecology of Helicoverpa within cotton cropping regions.

The conference was held on the 23 - 27th of August, 1994 in Silsoe, UK.

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.

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).

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.

Annual Report 1994-1995

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

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.

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.

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

Field experiments at Narrabri in 1993, 1994 and 1995 have utilised overhead sprinklers and, portable rain-out shelters.
