The threshold guide is being developed by a national project, funded by the vegetable levy and administered by Horticulture Australia Limited, to indicate when to spray to obtain both effective DBM control and an economic result. This research was highlighted at a series of grower workshops held recently by Agriculture Western Australia around the south west and in the metropolitan area. When you take into account the added cost savings of time and equipment wear and tear, the actual savings are much higher. The national project on implementing Integrated Pest Management of DBM is also examining other aspects of management. During the workshops other trials in WA on insecticide application and natural enemies of DBM were also discussed.
