Argentine stem weevil damage to high sugar ryegrass infected with AR1 under field conditions

Abstract

Previous laboratory based studies indicate that, compared to standard cultivars, high sugar grasses (HSG) can have lower endophyte and peramine concentrations and suggest that N fertilisation may result in further reductions in endophyte and alkaloid.
