Soils that disperse tend to have poor drainage; excessive swelling closes soil pores, which also block up with dispersed clay, sand and silt.

An evaluation of drip irrigation for cotton production

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

By now most people in the cotton industry have formed an opinion about Siratac as a concept and Siratac as a Company.

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.

The adult stages of the two Heliothis species found most abundantly in the summer cropping areas of Australia (H. armigera and .H. punctigera) are easily distinguishable and have been so for some time.

A knowledge of dispersal is essential to an understanding of population control and to the management of insecticide resistance.

A contribution was made to the last ACGRA conference on "The duration.of insecticidal activity against Heliothis larvae on cotton".

Numerous studies on the effect of the nectariless gene on insect pests of cotton have been carried out both overseas and in Australia.

In 1981 we released SICOT 3 to the industry.

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.

With increasing problems of resistance to chemical pesticides amongst cotton pests, especially Heliothis, more attention is being given to biological control agents, including pathogens.

With the appearance of pvrethroid resistance in Heliothis armigera during the 1992/3 cropping season a strategy aimed at limiting the development of widespread resistance was rapidly implemented .H.

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 publicit

The pink spotted bollworm (Pectinophora scutigera) has been an important.pest of cotton since 1924 in coastal, and sub-coastal Dawson-Callide regions of central Queensland.

Different cultivars are now becoming commercially available including Australian bred cultivars, and cotton growers now have a choice of which cultivar to plant.

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

At Emerald, in the 1982/83 season, significant levels of field resistance in Heliothis armiger to synthetic pyrethroid insecticides were detected.
