With the recent launch of a new jetting product for long wool lice and fly control, the special treatment permits for diazinon and Vetrazin have ceased. Agriculture Western Australia wool residues development officer Di Evans said now a more suitable long wool treatment was available, the special permits co-ordinated by the agency are no longer required. However, the current registered use of diazinon and Vetrazin in short wool will continue as normal. So if growers face a severe fly wave within two months of shearing, there is no need to register for a special permit to use Vetrazin in the month before shearing. Similarly, if lice are found between six and 10 months after shearing, growers no longer need a special permit for diazinon.
