“…The improper handling, packaging, storage, and transportation may result in decay and production of microorganisms, which become activated because of the changing physiological state of the fruits and vegetables. Fruits, due to their low pH, higher moisture content, and nutrient composition, are very susceptible to attack by pathogenic fungi, which in addition to causing rots may also make them unfit for consumption by producing mycotoxins (Fatima et al., 2009). Virtually all postharvest diseases of fruit and vegetables are caused by fungi and bacteria.…”

Postharvest fungal attacks on fruits such as apricots and loquats are common. Diseased fruit samples were collected from Murree's local fruit markets. The disease‐causing pathogens were identified utilizing molecular, microscopic, and morphological characteristics. Alternaria alternata and Aspergillus niger were identified as the pathogens responsible for brown rot in loquat and black rot in apricot. To combat these fruit diseases, iron oxide (Fe2O3) nanoparticles were synthesized using Bacillus subtilis and were characterized using various techniques. X‐ray diffraction examination validated the size of iron oxide nanoparticles. The presence of several capping agents in the synthesized nanoparticles was confirmed by Fourier transform infrared analysis. Scanning electron microscopy revealed the spherical morphology of nanoparticles, whereas energy‐dispersive X‐ray proved the presence of different elemental compositions. After completing antifungal activities in vitro and in vivo, it was discovered that a nanoparticle concentration of 1.0 mg/mL efficiently suppressed the growth of fungal mycelia. Fungi growth was effectively inhibited in fruit samples treated with 1.0 mg/mL nanoparticles. The results of successful in vitro and in vivo antifungal activities imply that iron oxide (Fe2O3) nanoparticles play an important role in ensuring fruit quality against pathogenic attacks. Bacterial‐mediated iron oxide can be widely used because it is less expensive and less harmful to the environment than chemically manufactured fertilizers.

“…Они содержат полигидроксильные группы, благодаря чему они водорастворимы и поэтому используются в качестве гидрофильных природных полимеров в различных фармацевтических препаратах [5]. Кроме того, полисахарид бамии используется в качестве связующего для таблеток, материала для пленочного покрытия, а также в качестве эмульгатора или стабилизатора [6,7,8] [9], что обесценивает коммерческую стоимость плодов [10], а также из-за патогенных грибов, которые находятся в воздухе и оседают на поверхности плодов бамии [11,12,13,14].…”

Relevance. Okra is rich in useful substances: carbohydrates, dietary fiber, lipids, amino acids, vitamins A, K, C, mineral salts. The polysaccharides contained in okra fruits are chemically inert, non-toxic, biodegradable and biocompatible polymers. To expand the range of vegetable products in our country, a study of okra in the summer-autumn turnover in a film greenhouse was carried out. Material and methods. The aim of the research was to substantiate the elements of the technology for growing okra in film unheated soil greenhouses under the conditions of the 3rd light zone. Research was carried out in 2019-2020 on the basis of the Educational and Scientific Production Center "Vegetable Experimental Station named after Edelstein" of Russian State Agrarian University - Moscow Timiryazev Agricultural Academy in the summerautumn turnover in a film unheated ground greenhouse. The objects of the study were the varieties: Damskie palchiki, Krasniy barkhat. Results. Based on the results of studying the effect of the formation of okra varieties in one and two shoots on growth and yield in the conditions of summer-autumn turnover in film soil greenhouses, we recommend growing plants of the Damskie palchiki variety in 2 shoots to obtain the highest fruit yield, Krasniy barkhat plants in one shoot.
