Other claims from this paper (19)
- Intervention effect WL 29,226 at 0.5–2 kg/ha controlled annual monocot weeds including Alopecurus myosuroides.
- Observation The treatment caused no adverse crop effects at 0.5–2 kg/ha.
- Mechanism WL 29,226 remained at the soil surface and favored emerging-shoot uptake.
- Mechanism The herbicide was transported predominantly through xylem toward dividing tissue.
- Intervention effect Roots were inhibited only on direct contact with the compound.
- Mechanism Stem-apex position relative to the soil surface determined crop-weed selectivity.
- Mechanism Weed mesocotyl elongation brought meristems to the soil surface and herbicide during emergence.
- Mechanism Wheat stem apices remained deeper until leaf sheaths protected the meristem.
- Mechanism Planting depth and near-surface weed germination enhanced herbicide selectivity in the field.
- Intervention effect Wheat lost tolerance when it germinated in direct contact with the herbicide.
- Intervention effect WL 29,226 controlled many dicot weeds under field conditions.
- Observation Dicot weeds displayed some tolerance in pot experiments.
- Mechanism Limited shoot transport to the apex explained dicot shoot tolerance.
- Mechanism Broadleaf weed control appeared to occur mainly through root-growth inhibition.
- Association Rapid root elongation increased herbicide tolerance in sugar-beet.
- Association Rapid root elongation increased herbicide tolerance in cotton.
- Association Soil moisture favored availability of WL 29,226 to seedlings.
- Mechanism Low temperature improved herbicide performance by slowing shoot emergence and prolonging exposure.
- Observation After emergence, shoot uptake became less efficient.
