Ongoing research at ACRI into cotton diseases confirmed the need for best practice to be exercised to avoid disease transfer from one location to another.The need for this was confirmed by pathology staff at ACRI who tested vehicles visiting ACRI and found Black root Rot , Veticilium and Fusarium pathogens present . This clearly presented a risk to the research trials at ACRI especially if Fusarium Wilt was to be imported onto the farm. It was also recognised that ACRI is a hub of the Cotton Industry with many grower visitors and that many off station sites are visited by ACRI staff. The pathology staff advised that in order to prevent disease transfer it would be necessary to improve the washdown facilities at ACRI and adopt a come clean go clean policy.The facility would also double as a best management practice demonstration facility to industry.
