Pomegranate wilt. 0. The integration of PS treatments with CA storage could provide an alternative to synthetic fungicides for the management of pomegranate postharvest decay. Layer-by-layer self assembly can be used in the formation of multinanolayer edible coatings. Additionally, decay was periodically assessed on intact pomegranates stored at 5°C for up to 7 months. Conidia were hyaline, aseptate, allantoid, and (4) 4.5 to ... Optimum postharvest pre-treatments and storage conditions play a significant role in retarding physiological responses and disorders as well as extending the shelf life of minimally processed fruit and vegetables. Pomegranate wilt (Ceratocystis fimbriata) has been the most important disease in Karnataka and Maharashtra. During the in vivo biocontrol studies, strain A5 and extracted compound was found to be very effective against pomegranate fruits infected with all the 36 pathogenic isolates, illustrating its potential to be utilized as a widely acceptable biocontrol agent against oily spot disease. In recent years, there is a great increase in the pomegranate cultivation area in the country. Arils were analysed for physicochemical quality attributes on day 0, 3, 6, 9, 12 and 15.

HWT induced the expression of CpPGIP and promptly induced the expression of CpNPR1, and then regulated the expression of the CpPR1 gene, which may enhance the resistance of the fruit to anthracnose disease and reduce the decay rate. Pomegranate (Punica granatum L.) is one of the important fruit crops in northern Karnataka. Following treatment, FLU applied at 20°C at the rate of 100 mg/l produced a residue of 0.25 mg/kg (active ingredient, whole fruit basis), this value increased respectively by 2.7 and 4.9 fold when FLU was applied at 300 or 600 mg/l. Fungal issues are part of growing pomegranate plants. Finally, heavy infection resulted in the whole tree dying, causing severe yield losses. All inoculated plants declined after a month similar to the ones observed in the orchard. Higher SSC and more reddish colouration in the fruit peel were noted at harvest and during cold storage in pomegranates from SDI and RDIripe. A series of field surveys conducted from 2014 to 2017 identified the most common and important pathogens causing disease on pomegranate in Florida (KC and Vallad 2016).

The pomegranate, native to Persia, had its first domestication in Iran about 2000 BC. Use of heavy and ill drained soils, close planting, excessive irrigation and fertilizers predispose the plant for disease complex. Majorly the crop yield is affected by fungal infections and pests invasion. Fungi live outdoors in soil and on plants and trees as well as on many indoor surfaces and on human skin. Bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. P. palmivora was reisolated from root tissues of inoculated plants. Differences were found in several of the juice parameters examined during storage, implying that each cultivar may require a specific storage protocol to maintain their taste and nutritional quality. 2009). This has spread to most of the pomegranate plantations in India resulting in huge economic loss. Pomegranate Growers’ Association (POMASA) jointly funded a survey of the post-harvest fungal diseases that threaten South Africa’s emerging pomegranate industry. Alternaria fruit rot – Alternaria is also called black rot and causes damage to the Pomegranate fruit in the form of wounds and rot on the interior of the fruit. Chlamydospores were 23.0 to 42.5 μm in diameter. Antagonist protection was higher when applied at a concentration of 10 8 spores/ml before inoculation. Conidia were hyaline, one-celled, elongate to fusiform, straight, and 11 to 17 × 4 to 6 μm (average 14 × 4.7 μm). Results showed that after 8 or 19 weeks at 5 °C plus 7 days of shelf life at 20 °C, some fruit quality attributes such as the soluble solids content (SSC), anthocyanins and fruit colour were enhanced by deficit irrigation. Presently, it is cultivated in India, Iran, Turkey, China, Spain, USA, Morocco, Egypt, Israel, Afghanistan, Pakistan, Greece, Azerbaijan, Yemen, Jordan, Portugal, Cyprus, Italy, Saudi Arabia, Argentina, northern parts of Chile, and to a lesser extent, in Burma, and Japan.

Seven plant extracts were tested for their efficacy in which, maximum of 93.4 and 88.1% inhibition of mycelial growth of fungus was observed in eucalyptus extract followed by garlic extract at 10% concentration, respectively. Yujinxiang) were dipped in hot water at 53 degrees C for 3 mm. Furthermore, HWD could clean the surface of fruits, melt the epicuticular waxes, cover and seal the stomata. However, at lower concentrations, toxin production was affected more than the growth, as evidenced by minimum inhibitory concentrations (MIC) of chitosan derived for toxin production and mycelial growth. Planting systems range from rows 3.6 to 5.8 m and in-row spacing from 1.5 to 5.2 m, with row spacing often determined by equipment preferences for other crops. Most of these derivatives exhibited high inhibition percentage (> 90%) of spore germination at 1000 mg/L. The fruit will keep many weeks at room temperature and longer in cold storage. Pycnidia were globose and black with thin, membranous, pseudoparenchymatic walls, 80 to 140 μm in diameter. ; and, pre-treatment of produce with UV-C light or heat.

More than 90% of Spanish commercial plantings are located in the Southeast area of the country (Alicante and Murcia provinces). Optimum storage conditions are required to maintain overall fruit quality thereby reducing postharvest losses and improvement of marketability of pomegranate fruit. The incidence was higher in Solan district where the infected fruits were often seen in the form of dark brown to black fruit mummies scattered on the orchard floor. Cardinal minimum growth temperatures were 8 to 10°C, optimum at 27 to 30°C, and maximum at 35°C. Among the various fungal diseases, anthracnose caused by Colletotrichum gloeosporioides (Penz) Penz. This is the first report of the occurrence of shoot blight and canker disease of pomegranates in Greece caused by the fungus Pilidiella granati Saccardo. Across all treatments, CO2 respiration rate (RCO2) increased from 2.8-28.3 ml/kg h, while O2 respiration rate (RO2) increased from 2.6-27.2 ml/kg h. Storage temperature and time influence the respiratory quotient (RQ) of pomegranate arils. Finally severity of the disease on a tree was calculated. Major diseases of pomegranate in Florida Anthracnose (Colletotrichum sp.) Together, these results confirm that HWT could reduce disease incidence and induce resistance, and thus maintain postharvest quality during storage and prolong the shelf-life of papaya fruit.
