Other claims from this paper (10)
- Intervention effect Bacillus subtilis strain MBI600 gave the strongest and most consistent greenhouse sheath blight suppression among nine strains.
- Intervention effect MBI600 alone at three tested concentrations reduced sheath blight severity.
- Intervention effect MBI600 at those concentrations combined with at least 33% azoxystrobin further reduced sheath blight severity.
- Method / resource A dose-response model relating MBI600, azoxystrobin and sheath blight severity was established.
- Observation With half-rate azoxystrobin, the estimated MBI600 EC50 was 10 4 CFU/ml.
- Intervention effect Field-applied MBI600 alone reduced sheath blight severity.
- Intervention effect Field-applied MBI600 alone did not significantly increase grain yield each year.
- Intervention effect Combining MBI600 with half-rate azoxystrobin reduced sheath blight severity to the full-rate fungicide level in all four years.
- Intervention effect The combined treatment increased rice grain yield by 14 to 19%, comparable with full-rate fungicide in three of four years.
- Recommendation The authors identify MBI600 with reduced azoxystrobin as a viable rice sheath blight management option.
