“…Food additives are widely studied substances in controlling preharvest and postharvest pathogens. Previous studies reported that bicarbonate salts were able to control various plant pathogens in vitro (Punja and Grogan 1982;Palmer et al 1997;Mills et al 2004;Samapundo et al 2007) and in vivo (Gabler and Mecteau et al 2002;Sivakumar et al 2002;Karabulut et al 2003Karabulut et al , 2004Karabulut et al , 2005aKarabulut et al , 2006Karabulut et al , 2007Alvindia et al 2004;Arslan et al 2006;Ilhan et al 2006 (Olivier et al 1998). Ammonium bicarbonate, sodium bicarbonate, potassium carbonate, calcium propionate, or potassium sorbate reduced black root rot on carrots caused by Chalara elegans Nag Raj & Kendrick (Punja and Gaye 1993).…”

The efficacy of eight food additives as possible alternatives to synthetic fungicides for the control of soilborne pathogens, Fusarium oxysporum f. sp. melonis, Macrophomina phaseolina, Rhizoctonia solani, and Sclerotinia sclerotiorum was evaluated in this study. A preliminary selection of food additives was performed through in vitro tests. The ED 50 , minimum inhibition concentration (MIC), and minimum fungicidal concentration (MFC) values showed that ammonium bicarbonate and potassium sorbate were more toxic to soilborne pathogens compared to other food additives with few exceptions and, therefore selected for further testing in soil. The inhibitory and fungistatic efficacy potassium sorbate were higher than that of ammonium bicarbonate in in vitro tests. Potassium sorbate completely inhibited F. oxysporum f. sp. melonis, M. phaseolina, and R. solani at 0.6% in soil tests. In contrast ammonium bicarbonate at 0.6% was inferior compared to potassium sorbate. Ammonium bicarbonate achieved to control all fungi at 2% that is the highest concentration used in this study. Potassium sorbate showed higher toxicity to all fungi compared to ammonium bicarbonate in soil tests. Both ammonium bicarbonate and potassium sorbate increased the pH of soil. The rate of pH increase was higher in ammonium bicarbonate.

“…Disease incidence (DI) data was expressed as the percentage of fruits showing particular disease symptoms out of the total number of fruits in each treatment, while lesion diameter and decay area were expressed accordingly (Sivakumar et al 2002) and other physical and physiological parameters such as percentage loss in weight (PLW) and fruit decay. The numbers of fruits for observations were 30.…”

-Introduction. Kinnow is an important citrus crop grown in India, which suffers from several postharvest diseases during storage. Hence, an attempt was made to combat such diseases with the botanicals Aloe vera, Eucalyptus and Ocimum on Kinnow mandarin to prolong its availability for a longer time. Materials and methods. For this, in vitro and in vivo studies were conducted. The poisoned food technique was used for in vitro studies, and, for in vivo studies, Kinnow fruit were pre-inoculated with pathogens (Penicillium digitatum and P. italicum), treated with different botanicals, then stored at (5 ± 1)°C temperature and 85-90% RH. Results and discussion. Our results indicated that all botanicals inhibited the growth (colony diameter) of both pathogens over untreated PDA plates, but the inhibition was the strongest by Aloe vera extracts. Similarly, under in vivo conditions, all botanicals influenced the decay incidence, decay loss, lesion diameter, respiration rate, ethylene evolution and physiological loss in weight, but Aloe vera was the most effective. All the botanicals were able to retain postharvest quality of Kinnow fruits without any adverse effect on quality parameters such as TSS, TA and ascorbic acid. Under in vivo conditions, the incidence of Penicillium italicum was higher than P. digitatum; however, it was the reverse under in vitro conditions. Conclusion. Thus, it is evident from our studies that botanicals have the potential to control green and blue mold without causing any injury or harmful effects on Kinnow mandarin; botanicals can be recommended as a safe method for extending its storage life while maintaining fruit quality at the same time.India / Citrus / mandarins / fruits / postharvest control / biological control / respiration rate / keeping quality Efficacité antifongique de certaines espèces botaniques contre d'importants agents pathogènes d'après-récolte chez la mandarine Kinnow et leur utilisation pour maintenir la qualité après-récolte.Résumé -Introduction.

Résultats et discussion. In vitro, nos résultats ont indiqué que chacune des espèces botaniques testées a empêché la croissance (diamètre des colonies) des deux pathogènes dans les boites traitées par rapport aux boites non traitées, mais l'inhibition a été la plus forte avec les extraits ...
