Integrated weed management (IWM) is a system for managing weeds over the long term, and is particularly useful for managing and minimising herbicide resistance.
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.
The most accurate way to estimate the weed population of a paddock is to count the number of plants in an area of known size at a number of locations.
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%.
Barley grass is a common name for Hordeum glaucum and H. leporinum.
This trial examines the positive impact of crop competition, crop type rotation and the mouldboard plough on weed management.
The Weed Seed Wizard is a computer simulation tool that uses paddock management information to predict weed emergence and crop losses.
Brome grass (Bromus diandrus and B. rigidus) is one of the most competitive grass weeds in wheat.
