Tebuconazole significantly reduces wheat yield under terminal spring drought locations
Aims

The original aim of this experiment was to test whether application of foliar fungicide to crops moderately resistant/moderately susceptible to stripe rust with infection detected at GS39-45 and of average yield potential (1.5-2.5t/ha) results in a profitable yield response. However, the experiment was side-tracked by a somewhat surprising result.

Key messages

In this experiment foliar application of tebuconazole at label rates to a wheat crop (cv. Yitpi) at GS38-49 resulted in a significant yield loss (0.43t/ha or a 43 percent decrease relative to the control)
