The results of disease surveys have indicated a declining incidence of Verticillium wilt and seedling diseases and an alarming increase in the prevalence of Fusarium wilt, black root rot and Alternaria leaf spot.

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 develo

Disease surveys in November and March of each season have been undertaken on a regular basis since 1983.

A large collection of microorganisms with over 2000 isolates has been established at the Australian Cotton Research Institute for the purpose of identifying potential bio-control agents and developing biological contr
