Abstract
Tomatoes face disease in many forms; bacterial, fungal, and viral. There are only a few options for small growers to prevent or treat these diseases. The use of naturally occurring plant essential oils has the potential to be both accessible and a marketing benefit. Twelve plant oils (orange, peppermint, eucalyptus, ginger, thyme, garlic, basil, tea tree, rosemary, oregano, cinnamon, and clove) were screened against two tomato fungal pathogens, Fusarium oxysporum and Phytophthora infestans, as well as the bacterial pathogen, Xanthamonas campestris v. vesicatoria. Thyme, garlic, oregano, and cinnamon all showed potential for inhibiting pathogen growth. After determination of minimum inhibition concentrations, three treatments were tested in a greenhouse setting. None of the tested treatments were found to be effective under the testing parameters. Further testing is needed to determine if the oils with inhibitory properties on the pathogens can be used to form a workable inhibition treatment in tomato crops.
