Nearly 100 plant introductions, ranging in maturity from 0-9 and representing over 90% of the current commercial germplasm were planted in plots of 1 row x 8 feet and 2 reps. Tebucouazole was applied at R1 and R3 at 4.0 oz/acre. Evaluation was done in both 2006 and 2007 with foliar symptoms rated every 14 days following fungicide application.
