Eastern star clover (Trifolium dasyurum C. Presl.) is a new pasture legume developed for use in short phases between extended cropping sequences in Western Australian dryland agriculture. Its delayed germination provides an opportunity to obtain almost complete control of the highly-competitive crop weed rigid ryegrass (Lolium rigidum Gaudin) through non-selective herbicide application and/or g...

Various mutations altering the herbicide target site (TS), can lead to structural modifications that decrease binding efficiency and results in herbicide resistant weed. In most cases, such a mutation will be associated with ecological fitness penalty under herbicide free environmental conditions. Here we describe the effect of various mutations, endowing resistance to acetyl-CoA carboxylase (A...

Abstract The ryegrass cyst nematode, Heterodera mani , is reported from Western Australia for the first time. Cysts were recovered soil samples collected on a broadacre cropping property near town of Esperance. production area dominated by cereal/oilseed rotation and species annual ( Lolium rigidum ) common weed issue in these paddocks.
