Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... In the lupin/wheat rotation, where simazine or atrazine are used in lupins, it follows that no diuron, bromoxynil or terbutryn is to be used in the cereal... Burning entire crop stubbles results in a high risk of wind erosion and is not recommended for most paddocks in Western Australia...

Optimal timing between applications is dependent upon the herbicides used and the weeds being targeted... The most common double Knock approach is to apply a systemic herbicide (for example Groups A, i or M are frequently used) when conditions are favourable for maximum translocation, and then follow it with a contact herbicide such as the bipyridyls (Group L)... double Knock trial results show consistently high performance when applied to small weeds (prior to tillering for grass weeds and prior to stem elongation for broadleafs) and the applications are applied on time with correct application set-up and climatic conditions...

Growers that have the weed seed bank under control will save herbicide costs; have greater rotational flexibility; have greater options to use diverse tactics that would otherwise be cost prohibitive; and by reducing the frequency of herbicide applications, will delay the onset of herbicide resistance... With any discussion on managing resistance we need to start with the basics and understand why we have the problem in the first place... Registration of high application rates by this technique may allow the control of resistant weeds that have survived a preceding application of a different mode of action...

Herbicides are not the answer to herbicide resistance... Sixteen of the growers practiced HWSC in the form of narrow windrow burning in only 12% of years (i.e. Herbicides only group)... In the eighth year of using this practice these growers had zero ryegrass in their focus paddocks and have averaged less than 1.5 ryegrass plants /m 2 ever since...

Controlling weed seed at harvest may be growers' best line of defence in combatting the on-going battle against herbicide resistance... With headers now dotted across winter crop paddocks in New South Wales and Queensland, the Grains Research and Development Corporation (GRDC) is reminding growers that driving down the weed seed bank is critical to managing herbicide resistance... "Driving down the weed seed bank is growers' best defence against herbicide resistance and that centres on two key considerations - dealing with the weed seeds already existing in the soil and stopping additional weed seeds from entering the soil...

Pioneering Western Australian research into techniques to control weed seeds in grain paddocks at harvest time has received international recognition... Dr Walsh said the research, funded by the Grains Research and Development Corporation (GRDC), proved that a high level of weed seeds is retained at wheat crop harvest time, providing further evidence of the effectiveness of harvest weed seed control (HWSC) in preventing weeds from replenishing the seed bank... "The research demonstrated that the four dominant annual weeds of Australian cropping systems - annual ryegrass, wild radish, brome grass and wild oats - retain 77 to 95 per cent of their seeds above a harvest cut height of 15cm at wheat crop maturity," he said...
