Other claims from this paper (13)
- Observation The nematode completed its life cycle in 45 days in wheat at 23°C.
- Observation The nematode multiplied in 26 of 61 cereal genotypes over ten weeks.
- Observation Other tested cereal genotypes sustained nematodes without multiplication.
- Observation Thirteen other cultivars sustained nematodes to varying degrees without multiplication.
- Observation Four cover crops were unsuitable hosts.
- Observation Attraction and root penetration patterns were similar in host and tolerant plants.
- Observation Nonhosts attracted fewer nematodes and none penetrated roots.
- Observation Some infected roots browned late, 55 days after inoculation, with a fungus present.
- Observation Nematodes were confined to cortical cells and fed from them.
- Observation Infected wheat cells showed disorganization, membrane integrity loss and cytoplasm disintegration.
- Observation Infected barley cells showed disorganization, membrane integrity loss and cytoplasm disintegration.
- Observation Infected barley cells showed nuclear hypertrophy and tannin-like granule deposition.
- Recommendation The nematode is likely a pest of major crops and merits management attention.
