High survival frequencies at low herbicide use rates in populations of Lolium rigidum result in rapid evolution of herbicide resistance.

Heredity - 1 Dec 2005

Neve P, Powles S

Abstract excerpt

The frequency of phenotypic resistance to herbicides in previously untreated weed populations and the herbicide dose applied to these populations are key determinants of the dynamics of selection for resistance. In total, 31 Lolium rigidum populations were collected from sites with no previous history of exposure to herbicides and where there was little probability of gene flow from adjacent resistant...
