Other claims from this paper (9)
- Intervention effect Azoxystrobin and myclobutanil were often equally and more effective than chlorothalonil at controlling rust in switchgrass.
- Intervention effect Superior rust control was obtained at shorter fungicide application intervals than at extended intervals in switchgrass.
- Association Year, product and application interval significantly affected dry biomass yield in switchgrass.
- Intervention effect Dry biomass yield protection was significantly better with azoxystrobin and myclobutanil than with chlorothalonil or no fungicide.
- Association Regression models with final disease rating or area under disease progress curve were significant, but explained only low to moderate variance in dry biomass yield (0.21 < R 2 < 0.60).
- Association Model estimate: biomass declined by 3 to 5% for each 10% increment in rust-related leaf necrosis in switchgrass.
- Association If rust problems are not managed and rust-related leaf necrosis reaches 80% or more by 1 September in each of 4 years, switchgrass biomass yield may be reduced by 24 to 40%.
- Association Rust severity significantly differed among study years in switchgrass.
- Observation Dry biomass yield was greatest in 2016 and lowest in 2014 in switchgrass.
