Other claims from this paper (7)
- Intervention effect Foliar spraying limited downward cyetpyrafen translocation in strawberry, with root-to-leaf factors of 0.002–0.006.
- Intervention effect Root irrigation produced preferential cyetpyrafen accumulation in roots, with root concentration factors up to 3.11.
- Intervention effect Root irrigation limited upward cyetpyrafen translocation, with leaf-to-root factors of 0.01–0.13.
- Observation Under foliar spray, photoisomerization to E-cyetpyrafen was the dominant pathway at 18.9–32.5%.
- Observation Under root irrigation, cyetpyrafen was mainly hydrolyzed to M-309 in roots at 7.7–22.5%.
- Observation Dietary risk for humans was acceptable under both application methods.
- Observation Under root irrigation, M-309 in soil was 45.0 μg kg –1.
