“…As demonstrated previously (Graham et al ., ; He et al ., ; Ohashi‐Kaneko et al ., ), ozone application to the root system in aqueous solution has no phytotoxic effect. This is most likely because the half‐life of ozone dissolved in water is short (typically less than 20 min) and because the method of application is to the growth substrate, which results in the limited exposure of roots to the gas.…”

“…Recently, interest has been shown in the use of sprayed ozonated water (O 3 wat) directly onto plants in order to control diseases. For example, O 3 wat has been used as an alternative to chemicals for the control of powdery mildew on cucumbers (Fujiwara and Fujii, ; Fujiwara et al ., ) or other airborne diseases, including early blight and leaf mould on tomato (He et al ., ). Few studies have explored the impact of O 3 wat on the control of soil‐borne pathogens on tomato (Ciccarese et al ., ) and little information exists on the use of O 3 wat as a new sustainable pest control strategy against nematodes (Sasanelli et al ., ).…”

Few studies have been carried out on the effect of ozonated water (O wat) on the oxidative stress of root systems and, in particular, in combination with biotic stress. The aim of this study was to determine whether aqueous ozone is effective in the control of root-knot nematode (RKN) infection and to investigate the concomitant changes in the basal defence system. A tomato cultivar susceptible to Meloidogyne incognita was treated with O wat as a soil drench. No negative effects were seen following ozone application in comparison with the control under the exposure conditions used. The treatment reduced significantly the nematode infection rate and induced changes in the morphology of nematode feeding sites, some of which were characterized by visible symptoms of senescence. The antioxidant response, as well as parameters of oxidative damage, were examined in untreated and O wat-treated galls at 2, 4 and 7 days after inoculation and compared with uninfected roots. High levels of reactive oxygen species (ROS), H O and malondialdehyde were generated in galls in response to combined abiotic and biotic stresses. Throughout the experimental period, the activities and relative transcript levels of the antioxidant enzymes catalase, superoxide dismutase and ascorbate peroxidase produced different responses when exposed to ozone treatment and/or infection. The results demonstrate how O wat protects tomato against the RKN M. incognita through the modulation of basal defence mechanisms.

“…In recent years, some progresses have been made in the application of O 3 micro/nano‐bubbles (O 3 ‐MNB) in preserving fresh FVs. For example, 1.6 mg/L O 3 ‐MNB was applied to treat the conidia suspension of Alternaria alternata isolated from tomato fruit for 5 min and reduced E. coli viable cells on leaf and pathogen population on tomato fruit during growth (He, Zheng, Li, & Song, 2015). Moreover, it was found that the alternative flow of O 3 nano‐bubbles decreased significantly the number of viable bacteria present in cabbage compared to the nano‐bubbles containing sodium hypochlorite (Ushida et al., 2017).…”

Postharvest handling is an important approach to reduce loss and ensure the global supply of fresh fruits and vegetables (FVs). Recently, nanomaterials are increasingly recognized for their great potentials in extending shelf life and maintaining the quality of postharvest FVs owing to their unique properties and outstanding functions with extremely small sizes. This study reviews critically applications of nanotechnology in shelf life extension and quality maintenance of postharvest FVs via nano-packaging, nano-coatings, and micro/nano-bubbles. The advantages of these nanotechnologies to effectively compensate for the shortcomings of the traditional methods are highlighted alongside future research directions at a large low-cost scale. Generally, nano-packaging, nano-coatings, and micro/nano-bubbles have the functions to modify gas or solvent permeability, inhibit pathogens infection, enhance antimicrobial capacity, and regulate the physiological activity of postharvest FVs. With the development of nanotechnology and quality control measures, it can be expected that green nanopreservation technology will be an important and novel alternative for the storage and transportation of postharvest FVs.

“…The dissolved oxygen concentration (DOC) of the micro nano bubbles and mixing pump water increased with the increase in mixing time. Results showed that treatment efficiency of Cladosporium fulvum conidia suspensions by using ozonated micro nanobubbles was good [5]. Some of the researches carried out have shown that MNBs are effective in cleaning, again reducing the waste of water.…”

Micro Nano Bubble (MNB) have been researched widely for their potental use in different applications such as disinfection, removal of toxic material from water, separation etc. Various parameters such as water temperature, system operating pressure, gas types and gas flow rates contribute in the size of the MNB generated. This research illustrates the influence of various parameters and their significance in size of MNBs generated. Experiments conducted showed that feed gas as a vital parameter for generating bubbles in nano size
