Raised beds are a long-term option for waterlogged sites and increasing crop yield on target areas. The Department of Primary Industries and Regional Development recommends that raised beds are part of a whole-farm water and salinity management program.
Herbicide resistance is the inherited ability of an individual plant to survive a herbicide application that would kill a normal population of the same species. Herbicide resistance does not equate to poor performance of a herbicide.
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. Use a quadrant, which may be square or circular, to carry out weed plant counts.
Herbicides play a vital role in integrated weed management programs. Knowledge of the mechanisms and activity of herbicides will improve the impact and sustainability of herbicides as a weed management tactic.
In-crop weed competition causes losses costing around $1 billion per annum for Western Australia. There are very effective strategic and tactical options available to manage weed competition that will increase crop yields and profitability.
