Spring Wheat Variety Performance and Response to Foliar Fungicide

Richland County, 2006

Joel Ransom and Scott Meyer, NDSU Extension Service, Fargo

This trial was planted on April 25 on ground previously planted to soybean near the town of Wahpeton on the farm of Mike Beeson. The experimental design was a randomized complete block with a split plot arrangement, with fungicide treatment as the main plots and varieties as the subplots with 3 replications. Plots were seeded at a rate of 1.2 million viable seeds/acre. Weeds were controlled with the labeled rate of Puma, Bronate and Starane applied at the 3-4 lf stage. Plots were fertilized with 150 lbs/acre N as ureas at the 2-3 lf stage. Plots receiving fungicide were treated with Folicur� at 4 fl oz/A plus NIS (Induce) at 0.125% v/v when the majority of the varieties were at the Feekes 10.5.1 stage (early flowering). The trial was harvested with a plot combine on August 14.
