Changes to the Stable Fly Management Plan will affect all Producers

By August 24, 2016 No Comments

The Stable Fly Management Plan has been in operation since 2013 but recent research by Dr David Cook of the Western Australian Department of Agriculture and Food, funded by growers through Horticulture Innovation Australia, and reported regularly in this magazine, has identified new and better ways to reduce stable fly breeding in Western Australia.

Changes that reflect these improvements were gazetted by the State Government on the 23 August. These include:-

  • The treatment of vegetable production waste has altered so that within 3 days of the end of harvest, the waste must be:
    • mulched, water turned off, and the area sprayed with insecticide as per the current management plan, or
    • deeply buried by stone burier with compaction or soil smearing, or by mouldboard plough, or
    • treated with an approved measure of deep rotary hoeing five times in five consecutive days
  • Restriction on the approved processes for treating poultry manure. All poultry manure used in the stable fly affected shires will need to meet the Australian Standard for composting (4454-2012) unless treated by an approved measure
  • Reject vegetable waste in pits must be sprayed with insecticide and buried at least 50cm deep (burial was 30cm deep previously)
  • Animal manure, soiled bedding, rotting hay and feedstuffs must immediately be piled into a mound and
    • treated by insecticide and left for 2 weeks; or
    • covered with plastic sheeting until no stable fly larvae or pupae are observed.

The use of the term  ‘Approved Measure’ in the new Stable Fly Management Plan is a measure approved by the Director General of the Western Australian Department of Agriculture and Food, for the control of stable fly, and is published on the Department of Agriculture and Food website.  The use of approved measures will enable a more responsive reaction to latest research or other developments.  Changes or new Approved Measures will be regularly published to ensure industry is kept up to date.
