2023 winter spring insecticide spray guide is now available
DPIRD’s 2023 winter spring guide is now available and can be downloaded for free at the department’s Insecticide spray guides for crops in Western Australia page.
This spray guide is updated every year to include chemicals and rates registered by the Australian Pesticides and Veterinarian Medicines Authority (APVMA) that can be applied to cereal, lupin, canola and field pea crops and pastures for controlling the common crop pests in WA.
A notable change in this spray guide includes the addition of cyantraniliprole, recently registered for use on native budworm and diamondback moth on canola.
Additional alpha-cypermethrin active ingredient concentrations are listed along with minor changes to dose rates of deltamethrin for native budworm on lupins, methomyl for native budworm and diamondback moth on canola, and sulfoxaflor for aphids on canola.
The spray guides are only a guide and growers still need to read chemical labels before use.
Not all insecticide trade names may be listed, so growers should also check with their retailers for any other registered insecticide options.
To download these spray guides and other useful insecticide information, visit the department’s Insecticide spray guides for crops in Western Australia page.
