The impact on grain yield by 21 foliar fungicides applied in the absence of a yield-limiting disease was evaluated across 18 individual experiments in 2019 and 2020 in a pivot irrigated field at the University of Arkansas System Division of Agriculture’s Jackson County Extension Center. The soybean cultivar ‘Terral REV49L88’ and ‘Armor 42D27’ were used in 2019 and 2020, respectively. Fungicides were applied at R4 in 2019 and R3 in 2020 in 30-ft replicated plots. The fungicides tested provided a grain yield benefit of >2 bu./ac 76% and 50% in 2019 and 2020, respectively, and >4 bu./ac 51% and 10% in 2019 and 2020, respectively. Only one fungicide, Miravis Top, provided a >4 bu./ac yield benefit in both years, while the other 20 fungicides were inconsistent. These data support the inconsistency among fungicides to provide a yield benefit in the absence of a yield-limiting disease. [ABSTRACT FROM AUTHOR] |
