Australian plague locust control: registered insecticides

Page last updated: Tuesday, 12 June 2018 - 12:37pm

This article provides information on chemicals registered for the control of the Australian plague locust in Western Australia.

Overview

  • There are many products with different trade names that contain the same active ingredient. This list is not exhaustive and does not imply any specific recommendations of brand names.
  • EC – emulsifiable concentrate, ULV – ultra low volume, CS – capsule suspension, SC – suspension concentrate.
  • Withholding period (WHP) - number of days are given for: (H) - harvest withholding period. For grazing WHPs refer to chemical label and export withholding period (ESI, EGI, EAFI) intervals are listed below in days.
  • Avoid overspraying stock. Refer to labels for withholding grazing periods for domestic markets. For animals destined for export: if overspraying does occur, withhold stock for slaughter until the export slaughter interval (ESI) on clean feed is met. Or the export grazing interval (EGI) on treated crops/pasture. EAFI (export animal feeding interval) is the minimum period that must elapse between application and grazing or harvesting of crop or pasture for feed. It is the least preferred interval option as there is considerable variability in decline of residues in mature pastures.
  • Many products are dangerous to fish and crustaceans. Do not contaminate ponds, rivers or waterways and do not spray flowering crops when bees are foraging.
  • Use of permitted chemicals is restricted to crops for which there are current registrations for other pests. Rates of application must not exceed the label rate for each crop.
