In the majority of cases, growers do not have a problem with excessive vegetative growth in their cotton crops. It is more likely that a field is not growing to potential.

As more than 94% of the Australian crop is exported, the world situation has greater bearing on the outlook for the Australian grower than most of his competitive counterparts who have the benefit of their own large d

I have been asked to address three major points: I . Why is risk management important? 2. Does a grower nee-d to know all the details of a market before he can become involved with risk management? 3.

During the 1991-92 season, a 1 ha block of unsprayed raingrown cotton near Dalby was sampled for parasite activity in heliothis larvae.

An experiment was conducted at Narrabri Agricultural Research Station during the 1991-92 season to investigate the response of a range of currently available cotton varieties to irrigation and nitrogen treatments.

Recent research has indicated that two species of native egg parasitoids, Trichogramma (Trichogrammanza) carverae Oatman and Pinto and Trichogrammatoidea bactrae Nagaraja, have potential as biological control agents o

This paper presents techniques used for rearing egg parasitoids on AGM eggs in an experimental facility at the QDPI Division of Plant Protection entomology laboratories in Toowoomba.

In surface irrigation systems we use beds rather than growing thee crop on the flat for several reasons.

This paper provides an overview of the Cotton Research and Development Corporation project DDI lL, which is in its final year at the University of Southern Queensland.

There are, few parasitoids which specifically attack the pupal stage. This is perhaps understandable since pupae are not readily accessible, being in the soil.

Retained hills are now a well-established management strategy in the Australian Cotton Industry.

Obviously, avoiding trafficking wet soil is one means of avoiding soil structural damage. Another is to use a vehicle with lower ground pressure, by using dual tyres, wide tracks, etc.

The importance of Heliothis has grown with the advent of resistance in H.armigera to various pesticides.

We have conducted a series of experiments at Trangie, Warren, Narrabri and Moree to examine the use of shallow leading tines in conjunction with rippers. Ripper depths of 300, 450 and 600 mm have been investigated.

In the 1991/92 season we started observations in both sprayed and unsprayed plots of different cotton varieties to record the numbers of fruit lost during the season and to identify the causes of shedding.

The companion project to SOILpak, "Soil management training for advisers to cotton growers" has made a good start in familiarising consultants and agronomists with structural recognition.
