This project identified a method of evaluating crop growth to predict yield response to Pix. * Two nutritional disorders were examined.

To develop, validate and implement a regional model of Helicoverpa population dynamics which considers the abundance, movement, oviposition, development and mortality of H.armigera and H.punctigera on all major hosts

Disease Surveys. Commercial cotton (Gossypium hirsutum L.) fields in the Mcintyre, Gwydir, Namol and Macquarie valleys of New South Wales were inspected in November and March each season.

This is an on-going project of breeding cottons adapted to Australian growing conditions, diseases and pests and markets.

Techniques for mass rearing egg parasites on eggs of the factitious host Sitotroga cerealella (Angoumois Grain Moth - AGM) were further developed and refined.
