In a choice bioassay carried out using tillers in Petri dishes, numbers of Rhopalosiphum padi on Elymus mutabilis infected with AR3050 were similar to numbers on meadow fescue infected with its natural endophyte Neotyphodium uncinatum and significantly less than the number of aphids on the meadow fescue endophyte-free control (Table 8).
