With lupins being susceptible and grown in close rotation to canola, particularly in the northern WA wheatbelt, lupin growers are facing increasing pressure from sclerotinia stem rot (caused by
In 2022, the department is conducting more than 300 research trials across the state from Kununurra in the north to Esperance in the south.
Aphids reduce yields by direct feeding damage which causes flower and pod abortion and occasionally plant death in lupins.
Lupins should be harvested as soon as they are mature to minimise significant yield loss.
40% lower germination was measured from seed of plants exposed to wetting and drying at maturity.
Information is provided here to assist management of diseases and viruses that occur in broadacre crops grown in Western Australia - cereals (wheat, barley, oats and triticale), pulses (field pea,
The extent of damage varies between seasons, but losses can be severe in years that favour aphid population development.
Wild radish (Raphanus raphanistrum) is highly competitive in crops and can cause a yield loss of 10-90%.
Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.
The Western Australian grain industry is a major contributor to the agrifood sector and the Australian economy.
