Winter Wheat Variety Response to Flag Leaf Foliar Fungicide Application in 2019–2020

Foliar fungicide can be an important tool in improving wheat yields, but its effectiveness is season- and variety-dependent. To evaluate the yield, test weight, protein responses of different commercial winter varieties to one foliar application around heading, we conducted a trial combining four two management treatments Manhattan during 2019–2020. The control treatment consisted no application, alternative 5 oz/a Absolute Maxx + NIS applied at heading. Varieties evaluated were Bob Dole, Larry, WB4269, Zenda. study was under no-tillage practices following previous soybean crop. Grain yield across averaged 47.8 bushels per acre 51.3 bu/a treatment. Zenda highest yielding variety (51.3 bu/a), followed by Larry (48.9 WB4269 Dole (~45.5 bu/a). statistical analysis suggested that all responded similarly hypothesize this because did not have enough observations build power. weight concentration only impacted showed effect (both usually greater as compared or WB4269). These results suggest increase due result dilution, likely extended period for nitrogen (N) uptake remobilization into grain. Further research needed statistically detect significant differences among their response fungicide.
