Tomato plants are a crop of great economic importance worldwide. Mexico is considered the world’s leading exporter of this vegetable, with a 24% market share. However, this crop can be affected by diseases such as bacterial freckle and bacterial cancer that can be introduced to plantations through infected seeds. Pesticides are used in agriculture for disease control and are considered a source of environmental pollution. Alternatives to the use of pesticides must therefore be sought. To this effect, electrolyzed water is a technology that has been shown to have antimicrobial activity. In this study, the antimicrobial activity of electrolyzed water on Pseudomonas syringaepv. tomato and Clavibactermichiganensis subsp.michiganensis was evaluated on cells suspension and tomato seed germination. Electrolyzed oxidizing water (EOW) and electrolyzed reduced water (ERW) treatments were applied for 1, 3 and 6 minutes. In addition, seeds were infected with each of the bacterial strains separately and electrolyzed water treatments were applied. Results show that oxidizing water is more efficient as an antimicrobial agent, as it achieved 100% growth reduction of the two bacterial strains after one minute of treatment. These treatments did not affect germination percentage, since germination percentages above 90% were obtained in all treatments and the seedlings were not affected in any of the evaluated variables.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
