Biopesticides based on Heliothis nuclear polyhedrosis virus (NPV), one of the Baculovims group, are notable for their potency, specificity and safety.

This project sets out to address some of the problems associated with growing dryland cotton using reduced and notillage practices, and look for possible solutions which will allow cotton to be integrated into sustain

Creation of lagoons or wetlands. River stabilization techniques. On farm reafforestation. The benefits and disadvantages of these to the landholder and to the environment.

The DLWC (Department of Land and Water Conservation) has operated the Central and North West Regions Water Quality Program for the past 5 seasons in the Namoi,Gwydir, Macquarie and Border Rivers catchments.

Green mind, Creontiades dilitus (Stal), is an important sporadic pest of cotton at the seedling stage and through early squaring.

At Tamworth, we have been monitoring H. armigera for carbamate resistance [thiodicarb (Larvin) and methomyl (Lannate, Nudrin) resistance since 1982. Thiodicarb resistance was first diagnosed in H.

The Australian cotton industry is heavily dependent on the use of chemical insecticides and herbicides.

In this edition of WaterWheel you will find a supplement detailing the research and development projects being undertaken through NPIRD.

Pyrethroid resistance levels in Helicoverpa armigera have continued to escalate slowly to around 80-90% but endosulfan resistance has stabilised at about half that level.

To develop resistance management strategies for organophosphates (OP's) carbamates, insect growth regulators (IGR's) and new insecticide groups, such as the pyrroles based on a sound understanding of resista

aims of this study were to: obtain base-line data against 12 pesticides and to conduct an initial evaluation of the current resistance status of field-collected cotton aphid strains.

The position of Cotton Industry Development Officer (C.l.D.O) in the Macquarie Valley was implemented in 1993-94 because much good research generated at Narrabri was not being adopted by local growers.

Aims: * Determine the economic impact of thrips on cotton and evaluate new means of control. * Evaluate the range and possible mechanisms of plant resistance to thrips and mites.

Objectives: A). To establish the uptake and partitioning patterns of potassium in cotton. B).

The effects of rotation crops and their management on soil properties, and irrigated cotton productivity and profitability were evaluated from 1993 to 1996 in some typical cracking clays (V ertisols) of the Namoi and

The objectives of this study were to: l) determine the role of soil instability and clay translocation in the formation of shiny-faced soil aggregates, 2) determine the roles of clay translocation and vehicular compac

OBJECTIVES 1993/4 Determine the common species of V AM fungi in the cotton areas of eastern Australia. Place the fungi in pot culture.

Over the period from 1990 to 1993, research was carried out investigating the regrowth of Australian cotton varieties after damage by haiI.

Objectives: To purchase a new nitrogen analyser in order to provide faster, more accurate analysis of cotton samples for a wide range of projects
