Landholders are responsible for control of locusts on their property. The Department of Primary Industries and Regional Development (DPIRD) is committed to providing relevant information to landholders to assist them with decisions on control.
Landholders will need to control hoppers and flying locusts that are causing damage on their own properties.
The main aim of landholder control operations is to kill locusts in the hopper stage.
Landholder locust spraying, yabbies and farm dams
-
Follow label recommendations for buffer zones to avoid any impact on yabbies in farm dams.
If spraying inside buffer zones then it is advisable to wait 14 days before attempting to restock the dam. -
After 14 days, restock the dam with a few yabbies in a cage that will act as biological indicators.
-
The yabbies will need access to mud to ensure it replicates their free state within a typical dam.If these yabbies are still alive after seven days, it can be assumed that the dam is now ok to go back into yabbie production.
-
If yabbie owners are concerned about residue levels from the spraying they could also get their dam water analysed at their cost (this can be expensive) by the ChemCentre or seek the advice of the chemical manufacturer on yabbie withholding times for particular chemicals.
