Other claims from this paper (6)
- Intervention effect Silicon combined with edifenphos reduced leaf blast severity by 22 to 75% compared with nonamended, untreated controls in upland rice.
- Intervention effect Silicon alone suppressed neck blast in upland rice as effectively or better than the full rate of tricyclazole when severity was low.
- Observation A 10% rate of tricyclazole was needed in addition to Si for neck blast control when severity was higher in upland rice.
- Intervention effect Silicon without fungicides and fungicides at full rate without silicon showed no differences in yield in upland rice.
- Intervention effect Applications of silicon made in 1995 had significant residual activity for disease control and yield in 1996 in upland rice.
- Recommendation Applying silicon to Si-deficient soils may permit reduced fungicide rates to manage leaf and neck blast in upland rice.
