Catalogue: Broadacre Field Crops DAFF QLD
Resistance remains for many years, until all resistant weed seeds are gone from the soil seed bank... Central Queensland (CQ) has no confirmed resistant weeds, although a small random survey by The University of Queensland identified six weed populations as having the potential to develop resistance... The primary aim of weed control is to minimise their impact on productivity, and resistance is much less likely to develop in paddocks with fewer weeds than in heavily infested paddocks...

Catalogue: GRDC Updates
Spray failures due to herbicide resistant weeds is increasing rapidly in most cropping regions... Every time a herbicide from the same mode of action group is used on a weed population, the selection pressure for resistance to that herbicide and to other herbicides with that same mode of action is increased... As resistance in a population is usually selected from a small number of individuals that have the resistance gene, the early stages of resistance often appear as small patches of weeds surviving a spray...

First spray at two leaf stage followed about four weeks later with a second spray using a different herbicide group... Fact Sheet: grdc.com.au/GRDC-FS-WildRadishManagement 7.44: GCTV Extension Files: Wild Radish 2nd Spray 7.56: Peter Newman: Australian Herbicide Resistance Initiative 7.67: This barley is at the stage where we would like to apply our second wild radish herbicide 12.17: spray... We want to use a double 40.609: knock approach of one herbicide followed by a different herbicide group and then ideally 45.379: we follow-up with other non herbicide tactics such as using harvest weed seed control to 50.42: remove any seeds of surviving weeds...
