The objectives of the project were (I) to evaluate potential biocontrol agents for seedling disease control, (2) to evaluate potential biocontrol agents for the control of Verticillium wilt of cotton and (3) to develop and compare strategies for the biocontrol of Verticillium wilt. It was also proposed that some preliminary work would be carried out to investigate the feasibility of biocontrol methods for the control of black root rot, Fu sari um wilt and Galathera syndrome. A major development in the course of the project was the shift in the emphasis from research on biocontrol of Verticillium wilt to that on biocontrol of Fusarium wilt. By the 1995-96 cotton growing season it was clear that the varietal resistance was working effectively against Verticillium wilt. Fusarium wilt, although largely confined to Queensland, was becoming a concern to the NSW and Australian cotton industry.
