When Do Foliar Pyraclostrobin Fungicide Applications Produce Profitable Soybean Yield Responses?

Fig. 2. These late-season color-infrared (CIR) images show three common examples of "the greening effect" of the soybean canopy from pyraclostrobin applications within three on-farm evaluation trials conducted in 2008 and 2009. The darker red color on the imagery indicates more vigorous soybean plants with greater biomass and/or greater chlorophyll content in fungicide-treated strips than in non-treated strips.
