Evaluation location: Colorado, United States
Beet leafspot (Cercospora) trial done by Dr. E.G. Ruppel, Fort Collins, Colorado, 1996. Field nursery was two-rows, length 22 inches, plant spacing 8-10 inches, randomized complete-block with 3 reps. Incolution began on June 28, but a downpour of rain halted efforts. Fortunately, hot dry conditoins after the rain permitted the inoculation to be completed on the 29th. The second inoculation was to be done on July 3, but a severe hail storm shattered leaves so badly postponing it until July 11 to allow leaves to recover. The epidemic progressed favorably due to warm days and nights. Nursery was rated on Aug. 27, Sept. 3 and 10 with the peak of the epidemic occurred close to the last rating.
