|a Bacterial spot of tomato (BST), predominantly caused by Xanthomonas perforans (Xp) in Florida, is one of the most devastating diseases in hot, humid environments. Bacterial resistance to copper-based bactericides and antibiotics makes disease management extremely challenging. This necessitates alternative new solutions to manage the disease. In this study, we used two novel hybrid copper and magnesium nanomaterials, noted as magnesium double-coated (Mg-Db) and magnesium-copper (Mg-Cu), to manage BST. In in vitro experiments, no viable cells were recovered following 4 h of exposure to 500 μg/ml of both Mg-Db and Mg-Cu, while 100 and 200 μg/ml required 24 h of exposure for complete inhibition. In a viability assay using the live/dead cell straining method and epifluorescence microscopy, copper-tolerant Xp cells were killed within 4 h by both Mg-Cu and Mg-Db nanomaterials at 500 μg/ml but not by copper hydroxide (Kocide 3000). In the greenhouse, Mg-Db and Mg-Cu at 100 to 500 μg/ml significantly reduced BST severity compared with micron-sized commercial copper bactericide Kocide 3000 and the growers' standard (copper hydroxide + mancozeb) (P < 0.05). In field studies, Mg-Db and Mg-Cu nanomaterials significantly reduced disease severity in two out four field trials. Mg-Db at 500 μg/ml reduced BST severity by 34% compared with the nontreated control without affecting yield in fall, 2020. The use of hybrid nanomaterials at the highest concentrations (500 μg/ml) evaluated in the field experiments can reduce copper use by 90% compared with the growers' standard. In addition, there was no phytotoxicity observed with the use of hybrid nanomaterials in the field. These results suggest the potential of novel magnesium-copper-based hybrid nanomaterials to manage copper-tolerant bacterial pathogens
