Resistance to herbicides in the broadleaf weeds Raphanus raphanistrum, Sisymbrium orientale, and Sonchus oleraceus as determined by random weed surveys in south-eastern Australia Open
Context Broadleaf weeds infest crops and reduce crop yield. The use of herbicides to control these weeds results in the evolution of herbicide resistance. Aims There is limited information about the extent and distribution of herbicide res…

A deletion upstream of the degron of <span><i>AcIAA27</i></span> leads to auxinic herbicide resistance in <span><i>Arctotheca calendula</i></span> Open
BACKGROUND Two populations of Arctotheca calendula (capeweed) from near Naracoorte, South Australia, were not controlled by 2,4‐D. These populations were investigated for resistance to 2,4‐D and other auxin herbicides. Aux/IAA genes were i…

An 18 base pair in-frame deletion in the degron tail of IAA2 provides resistance to 2,4-D and dicamba in Brassica tournefortii Open
A population of Brassica tournefortii from South Australia was suspected to be resistant to 2,4-D. This study aimed to determine whether resistance to 2,4-D and other auxinic herbicides was present in the population and identify possible r…

Frequency of herbicide resistance in wild oats (Avena spp.), brome grass (Bromus spp.) and barley grass (Hordeum spp.) as determined by random surveys across south-eastern Australia Open
Context Wild oats (Avena spp.), brome grass (Bromus spp.) and barley grass (Hordeum spp.) are significant grass weeds of crop production in south-eastern Australia. The presence of herbicide resistance in these weed species is a major limi…

The extent of herbicide resistance in Lolium rigidum Gaud. (annual ryegrass) across south-eastern Australia as determined from random surveys Open
Context Annual ryegrass (Lolium rigidum) is a major weed of crop production in southern Australia that readily develops resistance to herbicides. Resistance increases both yield losses and control costs associated with this species. Aims T…

Alternative Herbicides for Controlling Herbicide-Resistant Annual Bluegrass (Poa annua L.) in Turf Open
Poa annua is a cosmopolitan, cool-season grass species regarded as one of the most significant weeds of turfgrass. It is mainly controlled by herbicides; however, repeated use of herbicides in golf turf has resulted in the evolution of mul…

Resistance to Multiple PRE Herbicides in a Field-evolved Rigid Ryegrass (<i>Lolium rigidum</i>) Population Open
A population of rigid ryegrass ( Lolium rigidum Gaudin) from a field on the Eyre Peninsula, South Australia, was suspected of resistance to thiocarbamate herbicides. Dose–response studies were conducted on this population (EP162) and two s…
