Daytime applications were made between 9:00 a.m. and 11:00 a.m., whereas nighttime applications were made between 11:00 p.m. and 1:00 a.m. Two trials (I and II) were conducted in Gaines County in 2008, whereas the trials from 2009 and 2010 were conducted at the Texas A&M AgriLife Research and Extension Center in Stephenville. The number of replications for fungicide treatments varied by location totaling 4, 12. and 8 for trials in 2008, 2009, and 2010, respectively. Values within a column for each main effect are not different according to Fisher’s Protected LSD () [34].
