rowers know the importance and delicacy
of controlling onion rot and disease. Proper
management such as effective irrigation, avoiding
injury to the crop and more can lead to a healthy onion
crop. During the 2023 Great Lakes Fruit, Vegetable
and Farm Market EXPO, attendees had the opportunity
to learn about the Stop the Rot project presented by
Bhabesh Dutta and Lindsey du Toit.
Bhabesh Dutta, associate professor and Extension
vegetable pathologist at the University of Georgia (UGA)
has worked on bacterial onion diseases as a trained
phytobacteriologist since 2012. Dutta informed growers
about the Stop the Rot project and key objectives for
onion stakeholders.
Stop the Rot objectives
" The project has two broader objectives, " Dutta said.
" In our first objective, we utilized pathogenomics tools
to identify virulence factors and develop diagnostic
tools for bacterial pathogens in onion. We also aimed to
evaluate phenotypic resistance screening methods for
bacterial pathogens. Our second objective focused on
examining key production practices and environmental
factors that impact bacterial diseases of onion.
Economics and Extension activities were integrated into
both objectives. "
According to Dutta, the long-term goal of the Stop the
Rot project is to " support the overall profitability and
sustainability of onion production in the United States by
reducing pre- and post-harvest losses due to bacterial
diseases. " Finding practical and economical management
for onion growers will ultimately boost profits.
Lindsey du Toit, professor and Extension plant
pathologist at Washington State University (WSU)
and chair of the WSU department of plant pathology,
suggests onion growers implement an integrated
disease management program to combat onion disease.
" Using an integrated disease management program
is key, " du Toit said. " This includes using an optimum
fertility program, careful management of irrigation,
avoiding physical injury to the crop, using copper-based
bactericides, careful timing of undercutting and topping
