Summary

We assessed the impact of impartial electrolyzed water (NEW) on the incidence of rot on tomato ( Solanum lycopersicum L.) fruits inoculated with Fusarium oxysporum , Galactomyces geotrichum , and Alternaria sp. at websites with lesions. The inoculated fruits had been handled with NEW at 10, 30, and 60 mg liter-1 lively chlorine, with copper oxychloride fungicide, and with sterile distilled water (management) for three, 5, and 10 min. Within the experiment with F. oxysporum , 50 to 80% of the management fruits and 50 to 60% of the fruits handled with the fungicide exhibited signs of rot on the inoculated websites. The bottom incidence recorded was 30% for fruits handled with NEW at 60 mg liter-1 lively chlorine with an immersion time of 5 min. Within the experiment with G. geotrichum , incidence of rot on management fruits was 70 to 90%, and for remedy with fungicide rot incidence was 50 to 90%. NEW at 60 mg liter-1 lively chlorine considerably decreased incidence of symptomatic fruit: solely 30% of the inoculated fruits washed for five min had injury from rot. Within the experiment with Alternaria sp., 60 to 90% of the fruits within the management group and 60 to 70% of the fruits within the fungicide group had been symptomatic. The bottom incidence was recorded for the remedy by which the fruits had been submerged in NEW with 60 mg liter-1 lively chlorine for three min. On this group, 40 to 50% of the fruits exhibited signs of rot. These outcomes had been obtained eight days after inoculation. NEW, with 60 mg liter-1 lively chlorine, considerably decreased incidence of rot signs on fruits inoculated with one of many experimental fungi relative to the management (P ≤ zero.05). NEW at 60 mg liter-1 is efficient within the management of fungal rot in tomatoes.
