Project Number: 1245-32420-005-36
Start Date: Jan 01, 2012
End Date: Jun 30, 2014
Soil (soil amendments, compost) and irrigation water are major sources of pre-harvest contamination of fresh produce. We will utilize plant natural defense mechanism (glucosinolate-derived compounds) as a green manure to control attenuated strains of enteric pathogens in soil. Brassica plants will be grown in hoop houses. After crop harvest, remnant plant tissues will be tilled over as a green manure. Soil inoculated with attenuated strains will be sampled periodically for their persistence in presence of green manure.
