Winter Wheat Variety Performance and Response to Foliar Fungicide

Prosper, 2006

Joel Ransom and Scott Meyer, NDSU Extension Service, Fargo,

This trial was planted on September 16, 2005 on ground previously planted cropped to barley at the Propser Research site of NDSU. 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. Treatments were replicated three times. Plots were seeded at a rate of 1.0 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 using ureas in the spring as the plants were initiating new growth. 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 July 31. All varieties had good winter survival.

1 Yield of these variety may be lower than would be achieved in an actual field setting due to preferential damage to them by birds/rodents.

2The difference between the no fungicide and fungicide means was statistically significant for test weight. There was a highly significant variety by fungicide interaction for yield.
