A new weapon in the war against the Elm Leaf Beetle has been trialled by Latrobe City Council in Kay Street Traralgon and at the Sandbanks Reserve on the Latrobe River this season, and is showing great promise.

Latrobe City's Arborist in charge, Chris Dash, said an insecticide called Confidor was injected around the root zones of the trees where it is taken up by the root systems and translocated to the foliage. The method controls the beetles at the larvae stage before the visual damage has occurred.

"While the treatment requires specialised equipment used by contractors, which is beyond the scope of the home gardener, the trial is proving an effective method for Council in treating trees.

"The optimum time for applying Confidor is September to November and later treatments are effective provided there is no moisture limitations in the soil," Mr Dash said.

"Because of the nature of soil injection control methods, residents are advised that they should contact a qualified company to provide them with a quote to carry out this service," Mr Dash said.

In appraising the results of the trial to date, Mr Dash said a close inspection of the Kay Street Elms showed they were in a particularly healthy state this year with no sign of the normal damage incurred by Elm Leaf Beetles.
