Abstract

Root rot in storage can lead to considerable sucrose losses in storage and adversely affect factory processing as well. The use of fungicide treatments applied to the root surface prior to storage were investigated to determine if they could reduce storage rots caused by Botrytis sp., Penicillium sp., and Athelia sp. Roots of the sugar beet cultivar B-5 were produced using standard cultural practices. At harvest eight roots were placed in a mesh onion bags to establish experimental units. The study included nine fungicide treatments (applied as a root dip) and a non-treated check arranged in a randomized complete block design with four replications. Roots were then placed on top of an indoor commercial sugar beet pile and evaluated four times for root rot throughout the 120 day storage period. Area under the disease progress curve data showed an average reduction of 92% for Botrytis sp. and 71% for Athelia sp. for all treatments in comparison to the non-treated check. There was very little Penicillium growth on the roots and subsequently no differences between treatments. These data will aid the sugar beet industry in improving the storage of sugar beet roots.
