Abstract: A storage trial was conducted in 2002/2003 at the Potato Storage Management Centre of the Potato Development Centre, New Brunswick Department of Agriculture, Fisheries and Aquaculture in Wicklow, New Brunswick, Canada to study the efficacy of OxiDate™ for preventing the development of early blight (Alternaria solani) in potato storages. Two potato cultivars, Shepody and Norland, were used in this trial. Potato samples in mesh bags (20 lb. each) untreated with sprout inhibitors were placed in wooden pallet boxes commonly used in potato storages. A wooden divider divided each box into two portions. Six samples of Shepody were placed in one portion, and 6 samples of Norland were placed in the other portion. Two treatments (control and OxiDate™ 1:50) were replicated three times for each cultivar. Treatments were applied daily for 2 weeks (8 hr/day), and then once (8 hr) per week for the duration of the experiment. Results indicated that OxiDate™ treatment at the 1:50 rate helped reduce the level of early blight in storage over 16 weeks when compared to the untreated check.
