Populations of Xiphinema americanum on 37 plants in more than 40 weeds, woody plants, and crops were measured after 59, 118, and 169 days in the greenhouse. The populations of nematodes after 6 mo were highest on cinquefoil (Potentilla canadensis) followed in order by chicory (Cichorium intybus) and dandelion (Taraxacum officinale). Populations were moderate on apple (Malus sylvestris), but cucurbits, ragweed (Ambrosia artemisiifolia), and fleabane (Erigeron annuus) were poor hosts. Nematode populations disappeared after 118 days on nine other hosts.
