As a consequence of the project UA00060, vital information has been obtained on the seedbank ecology and population dynamics of brome in response to various management strategies developed through on-farm research... Results from the survey of grower paddocks on Yorke (YP) and Eyre Peninsulas (EP) in South Australia (SA) confirmed the species of brome grass infesting cereal crops of southern Australia as Bromus diandrus and Bromus rigidus ... Several studies were undertaken at Roseworthy to investigate the germination behaviour of different populations of brome grass ( B. diandrus and B. rigidus ) collected from sites on YP and EP. Clear differences were shown between species, with populations of B. diandrus germinating at a much faster rate than its close relative, B. rigidus ...

The project has identified lupins with improved tolerance to metribuzin # and germplasm of lupin and the four pulses with differential tolerance to herbicides with alternative herbicide chemistries... Large number accessions of lupin, chickpea, field pea, lentil and faba bean have been screened against four herbicides of different chemistries as part of the project... 6. Differential tolerance of pulses towards isoxaflutole Isoxaflutole (Group H, HPPD inhibitor), a herbicide registered in Australia for pre-emergent use in chickpea for control of dicot weeds, was tested against leading varieties of lupin, field pea, lentil and faba bean to assess whether or not they have acceptable levels of tolerance to this herbicide...

" PBA PhD - Improving metribuzin tolerance in lentil.. Furthermore the project will deliver capacity to Pulse Breeding Australia (PBA) through the up skilling of the scientific knowledge and capabilities, particularly in the area of plant breeding, herbicide understanding and plant physiology, to a key researcher of PBA (Mr McMurray)... and is in an area which is considered a major research objective of PBA. Expected outcome: This project will build the research capacity in PBA through delivering new knowledge, technologies and genetics to PBA lentil that will improve the metribuzin tolerance and subsequent weed control in new lentil varieties...

Blade, Kite, EGA Eagle Rock, and Sloop SA barley showed tolerance to metribuzin, exhibiting little change in seedling density and anthesis dry matter (DM) when treated with metribuzin (187.5 and 375 g/ha)... Estimates of regression parameter B (slope s.e.) for seedling density (plants/m2) and shoot DM (g/m2) of wheat genotypes treated with metribuzin (0, 187.5, and 375 g/ha) at a eld site at Cleve in 2004 Two-tailed t-tests were performed to compare differences in B (slope) values with Spear, a sensitive genotype... There is a need to identify alternative sources of metribuzin tolerance, which can be incorporated into Australian wheats...
