Helicoverpa armigera shows a much higher tolerance than Heliothis virescens towards the Cry lAc toxin present in INGARD and BOLLGARD II cotton. Unlike H. virescens, the major pest of cotton in the USA, some H.

Cropping systems experiments are currently being used to evaluate the sustainability of various cotton, systems. An important component is the inclusion of legume crops for grain or green manuring.

Linking crop agronomic, physiology and modelling studies are important for, assessing the potential and sustainability of different cropping systems in the, Australian Cotton Industry.

During their visit, the US Scientists interacted and shared experiences and

techniques with Dr David Nehl and Dr Om Jhorar of NSW Agriculture, Dr Stephen

Weed surveys conducted by Charles (1989), Roberts (1996 unpublished) and Taylor (2002 unpublished) indicate that the majority of weeds affecting cotton production in Australian farming systems are annual and ephemeral

To help understand the underlying basis of the resistance to pirimicarb, and hence improve the chance of effective management, Dr Robin Gunning and Dr Graham Moores (Rothamstead, UK) did a preliminary screen on resist

Fusarium wilt is caused by pathogenic fungi in the genus Fusarium, which infect the roots of susceptible plants and are able to spread throughout the vascular system, stimulating the production of gums and gels that b

This is the final report for project DAN168C. This project ceased after 1 year of operation.

Key factors in managing transgenic Bt cottons for the future are to have an effective resistance management strategy. An essential component of any such strategy is to establish a resistance monitoring program.

Field cropping systems in southern NSW have traditionally been associated with the production of grain crops.

CSIRO Textile and Fibre Technology were invited to be part of the to China during February.

Additional research work has been undertaken to answer a range of questions raised concerning various aspects of WEEDpak.

Included are:

Profenofos resistance is due to esterase mediated metabolism. Preliminary research suggests that an insensitive acetylcholinesterase is also involved.

The primary aims of the scoping study were to determine: * dominant and difficult-to-control weed species in each crop and fallow component of the different crop rotations used for dryland cotton production in the nor

Resistance is an ongoing concern with the management of H.armigera in the Australian
