Catalogue: GRDC Final Reports
In total, detailed dose response experiments were conducted on 25 populations of annual ryegrass that were suspected of being resistant to glyphosate... Dose response experiments examining populations with different resistance mechanisms showed that the target site mutation in SLR 77 resulted in a population that is less resistant to glyphosate compared with populations containing the reduced translocation mechanism, such as NLR 70... Using a knockdown rotation of the double knock in one year and glyphosate alone in the next year is predicted to result in glyphosate resistance occurring after 26 years for the translocation mechanism and more than 40 years for the target site mechanism (Figure 20)..

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...

Although residual herbicides will limit recropping options and will not provide complete control, they are a key part of successful fallow management.. The experiment showed that some of these populations were still only suppressed when sprayed with 12.8_L/ha... The most recent survey has focused on non-cropping situations with a large number of resistant populations found on roadsides and railway lines etc where glyphosate alone has been the principal weed management tool employed...
