1	Aspects of the population genetics and ecology of herbicide resistant annual ryegrass Matthews, John M., 1944- January 1996 (has links) (PDF) Bibliography: leaves 180. This study shows the widespread nature of resistance in L. rigidum populations, the tendency to genetic dominance even in early generations of selection and the propensity to display resistance to many herbicides. The fitness of resistant plants and the likely failure of herbicides for weed management suggests that an Integrated Weed Management programme is the best solution.
