Strobilurin fungicides can effectively control gray leaf spot (GLS) when applied at the tassel emergence growth stage VT. In 2007, UT evaluated GLS control and yields with the use of strobilurin fungicides in continuous corn in irrigated and non-irrigated fields using susceptible and tolerant hybrids. Location 1 was an irrigated, replicated test plot at the Milan Research & Education Center (MREC) in a four-year continuous corn rotation, where two strobilurin fungicides were applied in 20 gallons of water per acre. Two non-irrigated studies (Location 2 and 3) were conducted in fields with a second year corn rotation using 20 to 22 Early Roundup Ready (RR) and RR stacked hybrids and one strobilurin fungicide applied with a commercial ground sprayer at 20 gallons of water per acre. Location 2 involved replicated plots arranged as sprayed and unsprayed blocks at the MREC. Location 3 was planted on a local farm as side by side sprayed and unsprayed strip plots. The break even yield was estimated to be 3.8 bu/A at $4.00/bu corn. At Location 1 in irrigated continuous corn, yield increases of +7 to +25 bu/A resulted from a strobilurin fungicide application to corn at VT where conditions were optimal for heavy GLS infection. At Location 2, 11 of the 22 hybrids had a +3.8 bu/A yield increase while only 3 of the 20 on-farm strip plots had a +3.8 bu/A yield increase at Location 3. Abstract Table 1.
