Other claims from this paper (12)
- Observation Water shortage inhibited hatching of Heterodera avenae juveniles.
- Association In 1981, wheat knots increased from under 40 in mid May to nearly 80 in mid June.
- Observation In 1982, knot counts peaked at 80 per plant at the late April initial sowing.
- Intervention effect Grain yield loss peaked with late May or early June sowing.
- Association Maximum loss varied by cultivar tolerance from 520 to 880 kg/ha.
- Intervention effect Early or late sowing reduced potential yield.
- Observation Egg bearing females first appeared on roots 90 days after sowing.
- Recommendation The authors recommend beginning fallows in early August to prevent nematode reproduction.
- Observation Female numbers peaked at 16 per plant with sowing at the yield optimal date.
- Association Female numbers decreased in later sowings.
- Intervention effect Host resistance reduced female numbers.
- Intervention effect Ethylene dibromide rarely reduced female numbers.
