In 2020 the Department is conducting over 300 Grains Research trials across the state from Kununurra in the north to Esperance in the south.
The approach of summer has prompted a reminder to landholders across the grainbelt to check their properties for skeleton weed.
In Western Australia, competition from 7-90 capeweed plants per square metre in a wheat crop can reduce crop yield by 28-44% and net return by 25-76%.
Wild radish (Raphanus raphanistrum) is highly competitive in crops and can cause a yield loss of 10-90%.
This series of video tutorials has been produced to provide advice about the best ways to monitor and sample crops to diagnose and overcome constraints to crop production.
Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia.
Western Australia has seen major changes to the agronomic system, including a drying climate, more intensive cropping rotations and the widespread adoption of no-till.
In an integrated weed management program, control of weeds should occur in the fallow, pre-sowing, early post-emergent and in pasture phases.
Management of weeds, disease and nitrogen nutrition are ongoing challenges that limit yield potential.
This trial examines the positive impact of crop competition, crop type rotation and the mouldboard plough on weed management.
