Abstract
Herbicide resistance is a common occurrence in weeds of winter crops in southern Australia. In particular, annual ryegrass (Lolium rigidum) evolved resistance to most herbicide challenges. The extent of resistance is influenced by tillage practices, farming system, intensity of use of herbicides and the herbicide mode of action.Since 2001 approximately 1500 annual ryegrass samples from south-eastern Australia have been sent to the herbicide resistance testing service at Charles Sturt University. The results obtained from these samples were entered in a GIS database. Data on several agricultural parameters were also been entered into the database. This allowed the relationship between the mode of action of resistance and the geographic distribution of resistances in south eastern Australia to be investigated. Not unexpectedly, the resistance measured related to the farming system as influenced by soil type and rainfall regime. The geographic pattern of incidence provides a useful basis for implementing management practices to limit the incidence of herbicide resistance.
