  • PROGRESS IN COMMERCIAL VARIETIES - WHAT'S AROUND THE CORNER HERE AND IN THE U.S.A 
    Allaway, R.A. (1984-12-05)
    In agriculture we often hear reports of new wonder varieties that are about.to revolutionise agriculture, yet when these varieties are released, if.indeed they are released, they seem to fall far short of the publicity ...
  • USE OF PHEROMONE TRAPS AS INDICATORS OF THE SPECIES COMPOSITION OF HELIOTHIS EGGS LAID IN COTTON CROPS 
    Fitt, , Gary P.; Forrester, , N.W.; Cahill, M. (1984-12-05)
    Catches in pheromone traps can provide two types of information of interest to growers and researchers. Firstly, trap catches may directly indicate the abundance of moths in an area and hence the level of egg laying.in the ...
  • ASSESSING LOSS DUE TO BACTERIAL BLIGHT 
    Moffett, Melda L. (1984-12-05)
    Bacterial blight [Xanthomonas campestris pv. malvacearum (Smith 1901) Dye.1972], of cotton produces angular spots on leaves and squares, causes defoliation, lesions on sterns and bolls and reduces yield. Downward spread ...
  • The aims of the high quality breeding program 
    Luckett, D.J. (1984-12-05)
    The high quality cotton Namcala and its predecessor Hopicala have traditionally been grown on small percentages of the Australian cotton acreage (Mainly in NSW) as an alternative to the high yielding varieties such as ...
  • CONTAINING RESISTANCE 
    Twine, P.H. (1984-12-05)
    Resistance is seen as a manifestation of the most basic property of life, namely the capacity of organisms to evolve in response to changing environmental conditions and to adapt to new circumstances. Despite the detection ...
  • NOTES ON THE PEST STATUS OF AND SAMPLING METHODS FOR SAP-SUCKING BUGS IN COTTON 
    Adams, G.D.; Foley, D.H.; Pyke, B.A. (1984-12-05)
    In recent years sap-sucking bugs have been associated with early season damage.to cotton crops in most of the production centres in New South Wales and Queensland. Four species have been included in this pest complex: the ...
  • DISEASES IN THE 1983/84 COTTON CROP AND FUTURE DIRECTIONS FOR DISEASE RESEARCH 
    Allen, Stephen J. (1984-12-05)
    Commercial cotton crops in the major New South Wales production areas were inspected during the 1983/84 growing season. The purpose of these surveys was to assess the relative distribution, incidence and severity of the ...
  • PYRETHROID RESISTANCE IN HELIOTHIS ARMIGERA. 
    Gunning R.V.; Ferris, I.G. (1984-12-05)
    Intense selection pressure has led to the development of insecticide resistance
  • SHORT SEASON COTTON BREEDING 
    Reid, Peter (1984-12-05)
    At Narrabri we are continuing our breeding program to develop locally adapted early maturing varieties. At present there are no early varieties available commercially in Australia hut we feel that they could play an important role
  • Managing compaction in sodic grey clays 
    McKenzie, D.C. (1984-12-05)
    Soils that disperse tend to have poor drainage; excessive swelling closes soil pores, which also block up with dispersed clay, sand and silt. Poorly drained soils remain moist close to the surface for prolonged periods ...
  • The examination of soil structural deterioation in irrigated cotton fields 
    McGarry, D. (1984-12-05)
    At the 1982 Australian Cotton Growers' Research Conference the effects of land preparation at different soi1 water contents on soil structure and cotton growth was reported. In summary, land preparation on 'wet' rather ...
  • An evaluation of drip irrigation for cotton production 
    Constable, G.A.; Hodgson, A.S. (1984-12-05)
    An evaluation of drip irrigation for cotton production
  • The efficacy and degradation of current insecticides 
    Wilson, A.G.L. (1984-12-05)
    A contribution was made to the last ACGRA conference on "The duration.of insecticidal activity against Heliothis larvae on cotton". This paper.is primarily an update of the previous contribution and the more detailed.results ...
  • SOME FACTORS AFFECTING THE EFFICIENCY OF PHEROMONE TRAPS 
    Wilson, A.G.L. (1984-12-05)
    To optimize catches of Heliothis punctigera and H. armigera pheromone blends, dispenser and trap design have been evaluated and modified over a.7 year period. A laminated plastic lure loaded with appropriate pheromone ...
  • Why is a study of the genetics of Heliothis important in pesticide resistance? 
    Daly, Joanne (1984-12-05)
    The term 'genetics' encompasses a group of disciplines which study aspects of evolution. the first of these, molecular genetics, examines DNA, the raw material of evolution, and its organisation into genes. Genes code for ...
  • Field evaluation of an insecticide management strategy for the control of pyrethroid resistant Heliothis armigera 
    Forrester, N.W.; Cahill, M. (1984-12-05)
    In response to the development of resistance to pyrethroids by Heliothis armigera in 1983, an Insecticide management strategy was devised.in an attempt to prolong the field effectiveness of this and indeed, the other ...
  • BREEDING FOR AUSTRALIAN CONDITIONS 
    Thomson, N.J. (1984-12-05)
    I will first mention some of the features distinguishing "Australian Conditions". Our industry has developed almost exclusively as a mechanised high-input industry with water and nitrogen being supplied liberally together ...
  • THE PINK SPOTTED BOLLWORM - ITS SPREAD AND CONTROL 
    Page, F.D.; Modini, M.P.; Murray, D.A.H. (1984-12-05)
