The genetic material (DNA) of living organisms is structurally the same whether it is found in humans, plants, fungi or bacteria.

Documentation of crop yields and varieties in the Toowoomba Royal Agricultural Show Irrigated Crops Competition since 1972 demonstrates the great advances achieved by cotton breeders as new varieties have been introdu

Nutgrass (Cyperus rotundus L.), a plant native to India, is known as the world's worst weed .

In the arid and semi-arid regions of the world, irrigation has enabled previously unarable tracts of land to be used for a wide variety of agricultural activities.

The Australian cotton industry relies heavily on chemical pesticides for management of a diverse array of pest insects, weeds and diseases.

Question: When is a cotton plant not a cotton plant? Answer: All the time. Healthy cotton plants are always part of a mycorrhiza.

Helicoverpa punctigera (Wallengren) and H. armigera (Hubner) have a number of characteristics which make them highly successful pests of numerous crops in Australia, including cotton (Fitt 1989).

This paper looks at some of the differences between raingrown and irrigated cotton in Central Queensland, in particular: differences in basic inputs and differences between major problem areas.

A widespread problem of premature defoliation and physiological cut out of cotton has occurred in the Emerald Irrigation Area since the early 1980s. The problem was particularly severe in 1988 and 1989.

At the last ACGRA conference in 1990, it was reported that the Heliothis ID project had been running for approximately six months and species specific antibodies had not yet been obtained.

Farmers in Australia apply between 80 and 200 kg N ba-1 to cotton, but only part of this nitrogen is taken up and used by the crop, and the remainder is lost :from the plantsoil system.

Raingrown cotton in Northwest NSW and Southwest Queensland is not grown on metre beds, rarely has aerial applications, relies to a large extent on stored water, uses little or no fertiliser and large areas are harvest

Verticillium wilt of cotton is caused by a fungus (Verticillium dahliae) that infects the host plant via the roots and colonises the vascular system.

The cornerstone of most pest management programs world-wide is the "Economic Threshold" concept which is based on the principle of controlling a pest only if it is economically prudent to do so i.e.

At the Cotton Conference in 1990. I presented a paper which outlined the broad health and safety issues for the cotton industry in Australia. Health effects for the workforce included traumatic injury.

Previous research at Narrabri Agricultural Research Station and elsewhere has shown that mite populations increase more slowly on okra leaf cotton genotypes than on normal leaf genotypes (Bailey et al., 1978; Thomson,

There are basically three ways of preventing cotton farm runoff from contaminating the riverine.

The overall aim is to house current and future staff for our expanded research projects in the next decade.

The potential of leading tines to produce a finer tilth and allow operations at moisture contents \ Q higher than previously possible without producing smearing could possibly be exploited in implements for the renova

In July 1992 the 9th International Working Meeting on Soil Micromorphology was held in, Townsville, Queensland. It was sponsored by Sub-Commission B of the International, Society of Soil Science.
