Abstract
In-crop weed competition causes losses costing around $1 billion per annum for Western Australia. There are effective strategic and tactical options available to manage weed competition that will increase crop yields and profitability.
Weeds with herbicide resistance are an increasing problem in grain cropping enterprises. Integrated weed management (IWM) is a system for managing weeds over the long term and is particularly useful for managing and minimising herbicide resistance.
Growers are advised to adopt integrated weed management (IWM) to reduce the damage caused by herbicide-resistant weeds.
Herbicide resistant weed populations are found throughout all cropping areas of Western Australia. The number of resistant species and areas affected by resistance continues to increase. By understanding the implications and evolutionary processes of herbicide resistance, appropriate weed management strategies can be devised that will minimise the impact and delay the development of further resistance.
