| Popis: | The host status of different grass species for M. naasi has been studied in experiments with infested soil. Italian ryegrasses produced most females or eggs per g of root. The host status of perennial and hybrid ryegrasses was similar but better than that of the varieties of meadow fescue tested. Tall fescue and cocksfoot were poor hosts of the nematode. The development of few females on tall fescue cv. Pastelle, may be due either to the death of second stage juveniles in roots or to their migration into the soil. Increasing infestation level led to greater production of females and eggs in three species of ryegrasses but did not affect the poor host quality of tall fescue. |
