Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:

Perez-Jones, Alejandro

Abstract:

A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Biology and management of glyphosate-resistant creeping bentgrass

Creator:

Hancock, Daniel M.

Abstract:

A two year study was conducted at two locations to determine the effect of three perennial ryegrass (Lolium perenne L.) row spacings on creeping bentgrass (Agrostis stolonfera L.) biomass and seed production. At Location 1 in 2002, the creeping bentgrass biomass within the 7.62 cm row spacing was less than...
