WA Insecticide Guide 2026 - Autumn Winter

Abstract

Registered chemicals for broadacre crops in Western Australia The insecticides listed in the tables within this guide can be used on any crop appearing on the chemical label, if the rate used does not exceed the highest rate that is registered for use on that crop. 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. Unless otherwise specified, all insecticides listed are emulsifiable concentrates (EC). Other insecticide formulations are suspension concentrate (SC), wettable powder (WP), capsule suspension (CS), wettable granules (WG), emulsion (EW) dry flowable (DF) and water dispersible granules (WDG). Ultra-low volume (ULV) insecticides are not listed. Read the chemical label before use and check label withholding periods for grazing or hay/silage/fodder production before application. Please turn on punctuation if using a screen reader. The information tabled is a guide only. Whilst every care has been taken in preparation of the information, some errors or omissions may have occurred.
