Foliar diseases in greenhouse vegetables are usually controlled by the regular application of fungicides. The fungicides used for the diseases powdery mildew, downy mildew and Botrytis are generally effective, but over-use and misuse can rapidly lead to fungicide resistance. New fungicides are available to control these diseases in other crops but when this project started in June 2006 they were not yet registered or permitted for use in greenhouse vegetables. The project screened fungicides against the main foliar diseases and provided data to the industry to assist in obtaining permits and/or registration. The project also investigated a range of other options that growers can use to manage foliar diseases. It developed management strategies that enable greenhouse growers to minimise the use of fungicides and adopt a more integrated management approach. Individual fact sheets and posters produced as part of this project are available from this website, including a disease identification publication in Vietnamese.
