Abstract

Sucrose losses during postharvest storage of sugarbeet
(Beta vulgaris L.) maybe exacerbated by field diseases. This
study investigated the influence of curly top (causal agent
Beet severe curly top virus and related viruses) on storability
of sugarbeet roots during the 2005 and 2006 growing seasons.
Three sugarbeet cultivars varying for resistance to
curly top were evaluated both with and without the insecticide
seed treatment Poncho Beta (60 g a.i. clothianidin +
8 g a.i. beta-cyfluthrin/100,000 seed). At harvest, 8-beet
samples from each cultivar were collected and placed inside
an outdoor pile. Samples were removed at 40-day intervals
beginning on 31 October in 2005 and 1 November in 2006.
Sucrose concentration, frozen and discolored root area, and
root weight were evaluated. By mid-September plants from
Poncho Beta treated seed had curly top ratings that were 37
and 31% lower (P < 0.01) than plants from the untreated
seed in 2005 and 2006, respectively. After 124 and 131 days
in storage, roots from Poncho Beta treated seed had 8.5 and
5% more sucrose than roots from untreated seed in 2005
and 2006, respectively. Resistant cultivars and insecticide
seed treatments not only limit losses to curly top in the field,
but also in long term storage.
