Mice are seasonal pests that can affect any crop. Usually they favour paddocks with high stubble retention.
A pest mainly of young legume pastures and broadleaf crops but can also affect cereals. Commonly observed on loam-clay soils.
Salinity affects growth by reducing plant root ability to extract water from the soil, and chloride toxicity.
Canola is more susceptible to waterlogging than cereals after the seed has imbibed (absorbed water before germination).
Sclerotinia stem rot (Sclerotinia sclerotiorum ) is a fungal disease which infects most broad leaf crop and pasture species but not cereals.
Weevils are beetles with long snouts that can damage or kill young seedlings.
Blackleg is the most common and serious disease of canola in Western Australia. It is a sexually reproducing fungus that will overcome cultivar resistance genes.
Redlegged earth mite (RLEM) is a sap-sucking pest of crops and pastures. Canola and peas are particularly susceptible. They often co-exist with blue oat mites.
