W Australia seeks fruit fly controls
The Western Australia Department of Agriculture and Food is assessing three new fumigants to control Mediterranean fruit flies ( Ceratitis capitata) on tomatoes. Ethyl formate, propylene oxide and ethane-di-nitrile will be tested in a search for controls to satisfy inter-state quarantine authorities, the Department notes. The research is supported by the Vegetable Producers’ Committee of the Agricultural Produce Commission and Horticulture Australia. A project last year found methyl bromide suitable but alternatives are needed because methyl bromide is being phased out. The insecticide, fenthion, which is also used against fruit flies, faces suspension on many crops, including tomatoes, in Australia (see this issue).
