Rhizogenic Agrobacterium biovar 1 is the causative agent of hairy root disease (HRD) in the hydroponic cultivation of tomato and cucumber causing significant losses in marketable yield. In order to prevent and control the disease chemical disinfectants such as hydrogen peroxide or hypochlorite are generally applied to sanitize the hydroponic system and/or hydroponic solution. However, effective...

BACKGROUND Listeria monocytogenes has been estimated to cause >2500 illnesses and 500 deaths annually in the United States. Efforts to reduce foodborne listeriosis have focused on foods frequently implicated in outbreaks. Potential sources for L. monocytogenes infection not associated with outbreaks remain poorly understood. METHODS The Foodborne Diseases Active Surveillance Network conducts ...

Cultivation of vegetables with the hydroponic method is able to produce plants better quality values and efficient in land use when compared conventional ones. The comparison regarding production effectiveness nutrient uptake between two cultivation systems appears be little studied. This study aimed determine effect planting on growth romaine lettuce (Lactuca sativa) pakcoy (Brassica rapa) thr...
