Growers are urged to monitor and control native budworm to help minimise crop damage caused by this late-season pest.

Department of Agriculture and Food, Western Australia (DAFWA) entomologist Svetlana Micic says native budworm caterpillars have recently been detected in susceptible crops across the WA grainbelt.

“Native budworm (Helicoverpa punctigera) is a damaging pest of pulses and canola that affects both grain quality and yield,” Dr Micic says.

She encourages growers to be vigilant in controlling the pest as larvae can still cause damage in canola after windrowing in situations where many pods are green.

“Be aware of insecticide withholding periods close to harvest and remember that windrowing is classified as harvesting,” Dr Micic says.

Growers can access guidelines for monitoring and controlling native budworm through the GRDC’s Hot Topic resource, Budworm in Western Australia, and the DAFWA website.
