“…Ogawa and Iwabuchi [29] suggested that hydrogen peroxide promote germination of zinnia seeds by oxidation of germination inhibitors present in the pericarp. Oxidative abilities of H 2 O 2 are used in food industry for decontaminating fruits and vegetables from human pathogens and for reducing fungi responsible for post-harvest decay during storage [21,[30][31][32].…”

Abstract:The decrease of seed quality during storage is strongly associated with damage caused by free radicals. Some compounds of natural origin, known due to their antioxidative and antifungal properties, may be potentially used in organic production for seed treatment as an alternative to pesticides. The aim of the experiment was to study an ability of hydrogen peroxide and organic acid to improve germination, vigour and health of non-deteriorated and deteriorated zinnia seeds. Two seed samples, cv. Illumination and Orys, varying in initial infestation with fungi were tested. For deterioration seeds were kept at 30°C and 80% RH for 30 days. Seed quality tests were performed before and after deterioration for controls and seeds soaked in 3.0% hydrogen peroxide solution and in 1.0 and 5.0% solutions of ascorbic and lactic acids for 10, 30 and 60 min. The controls were untreated seeds, seeds soaked in 0.2% solution of Kaptan zawiesinowy 50 WP for 30 min and seeds soaked in distilled water for 10, 30 and 60 min. Treating zinnia seeds with organic acids more significantly affected seed germination and health after deterioration than before, and improvement of germination capacity was usually correlated with decrease of the percentage of abnormal diseased seedlings. Deterioration had no influence on mean germination time, whereas in particular cases treating seeds with hydrogen peroxide and organic acids negatively affected this parameter. After deterioration regardless of treatment increased number of seeds free from fungi. Lactic acid followed by hydrogen peroxide and ascorbic acid effectively limited growth of A. alternata, A. zinnia and Fusarium spp. on zinnia seeds, however at higher concentration negatively affected seed germination and vigour. Moreover, treating seeds with hydrogen peroxide and organic acids many a time increased seeds infestation with B. cinerea.

“…Symptoms on the fruit include soft, water-soaked lesions, turning brown before being covered with powdery, grey masses of spores (Naz et al 2018). Alternaria fruit rot is caused by species of Alternaria, including Alternaria alternata (Fries) Keissler (Fallik et al 1994;Troncoso et al 2005). Alternaria rot is characterized by dark sunken lesions accompanied by white to grey-green mycelial growth and conidia with a dark green to black appearance (Wall and Biles 1993).…”

Bell pepper (Capsicum annuum L.) fruit are susceptible to various molds, including grey mold and Alternaria rot. In this work, antagonistic bacteria isolated from disease-suppressive composts were assessed for their ability to reduce the mycelial growth of Botrytis cinerea Persoon and Alternaria alternata (Fries) Keissler as well as to suppress grey mold and Alternaria rot on bell pepper. Results showed that different bacterial antagonists reduced mycelial growth of B. cinerea and A. alternata by up to 49% and 53%, respectively. The bacteria provided inhibition of grey mold, reducing incidence and severity by as much as 43% and 67%, respectively. The isolates also provided strong inhibitory effects against Alternaria rot, decreasing incidence and severity by as much as 77% and 80%, respectively. Pseudomonas and Arthrobacter spp. were particularly suppressive to Alternaria rot. Results of this study suggest antagonistic bacteria may represent a potential method for controlling fruit rot of bell pepper.

“…Numerous studies have demonstrated the efficacy of dilute hydrogen peroxide in sanitizing fresh produce, including mushrooms , apples , melons , and eggplant and sweet red pepper (Fallik et al, 1994). Hydrogen peroxide treatments were ineffective in decontaminating sprouts or the seeds used to produce sprouts (Weissinger and Beuchat, 2000).…”

Outbreaks since the first edition of this book was published have been attributed to consumption of fresh commodities including but not limited to cantaloupes, mangoes, tomatoes, seed sprouts, and salad greens. Globally extensive research, published in thousands of scientific papers and documents, has focused on the microbiological safety of fresh produce. Disinfection methods whether conventional or based on new innovative technology fail to reduce pathogen loads on produce to levels consistent with product safety.Produce decontamination methods are surprisingly similar in the level of reductions in pathogens they achieve. Methods that are effective, irradiation and high pressure, are either not accepted by a large segment of consumers or not practical for all types of fresh produce. The intrinsic interaction of microbes with plant tissues, internalization, biofilm formation, and association with inaccessible sites contributes to the insufficient reduction in microbial populations to assure product safety. The key to improving the microbial safety of fresh products is the development of wiser strategies to avoid human pathogen contamination of the products rather than focusing on disinfect...
