GREAT LAKES EXPO NEWS
of onion crops to increase the speed of field curing and
topping onion bulbs to leave a longer neck. "
Stop the Rot learning opportunities at
Great Lakes EXPO with Dutta and du Toit:
* Bacterial rot in onions is caused by a diverse group
of bacterial pathogens and some of the prominent
genera that were actively associated belonged
to the following genera: Burkholderia, Pantoea,
Enterobacter, Rahnella and Pseudomonas.
* The distribution of bacterial rot-causing genera
may differ according to the geographical region of
onion production.
* Virulence factors in Pantoea species that aid in onion
rot are diverse.
* The type of irrigation practices and timing of
topping may impact bacterial rot and subsequent
storage quality.
" Generally, the risk of onion bacterial rots increases
the higher the amount of nitrogen used to grow onions,
particularly if some of the nitrogen is applied after the
onion crop has started bulb initiation, " du Toit said.
* The performance of copper-based bactericides is
variable across different onion-growing states.
THE PROJECT HAS TWO
BROADER OBJECTIVES. IN OUR
FIRST OBJECTIVE, WE UTILIZED
PATHOGENOMICS TOOLS TO IDENTIFY
VIRULENCE FACTORS AND DEVELOP
DIAGNOSTIC TOOLS FOR BACTERIAL
PATHOGENS IN ONION.
- Bhabesh Dutta, associate professor and
Extension vegetable pathologist at the
University of Georgia
" Historically, onion growers have applied copper
bactericides to try and control bacterial diseases, " du
Toit said. " Field trials with different bactericides in
multiple states across the USA showed that copper
bactericides had some efficacy against bacterial
diseases in regions such as Georgia, but had no efficacy
or very limited efficacy in most other regions. "
