Zanthoxylum Armatum

Alternaria fruit rot is a major disease caused by Alternaria alternata (Fr.) Keissl., a prolific fungal pathogen. Among post-harvest diseases of tomato, fruit rot induced by A. alternata is the most damaging. Antifungal agents are widely used to control post-harvest management of tomato fruits. However, negative impacts of fungicidal residues in edible fruits and vegetables on human health cannot be over ruled. Eco-friendly ways of controlling Alternaria rot in tomato fruits offer a novel way of tomato rot management. The current study proposes an alternate method in controlling tomato fruit rots through Zanthoxylum armatum DC essential oil (EO) application. Gas chromatography-mass spectrometry profiling showed eucalyptol and sabinene as major components of Z. armatum EO. Furthermore, EO applied (0.5–4.5 μl/ml) showed significant inhibition of A. alternata growth (p > 0.05) at 4.5 μl concentration tested. Lipid peroxidation assays revealed significant reduction in membrane damage in tomato fruits treated by EO compared to alone inoculated fruits with A. alternata. Elevated activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase coupled with enhanced antioxidants such as ascorbic acid, glutathione, proline, and total phenols in EO-treated fruits may be linked with better fruit rot management than control fruits inoculated with A. alternata-induced rot alone. Mycelia and spore production was dramatically reduced in EO applied tomato fruits over A. alternata alone in tomato fruits (p > 0.05). Interestingly, free radical scavenging activities of EO applied tomato fruits showed significant improvement compared to only pathogen-inoculated tomato fruits. Findings propose practical utility of Z. armatum EO as a plant-based antifungal for post-harvest management of Alternaria rot in tomato fruits.

Definition Of

The qualitative characteristics of mango fruits change throughout their development process and are also influenced by their duration. Harvesting at different times after the fruit set affects external and internal quality and the post-harvest behavior and management possibilities of the fruits. The objective of this study was to assess the evolution of the most important physicochemical and organoleptic parameters of cv. Osteen fruits concern the length of their stay on the plant and also to their post-harvest management. For this reason, fruits were harvested progressively in ten pickings. The study showed that mango fruits that are kept on the tree reach the best quality traits, corresponding to their physiological maturation. The length of the storage period needed to reach the consumption point varies greatly according to the harvesting moment and to the different environmental parameters, which also affect the organoleptic and physicochemical quality of the fruits. The number of days after full flowering were confirmed to be the primary information to consider when planning harvest with commercial use of the fruit, but interesting indications can be acquired through the definition of non-destructive (hardness, color) or destructive (dry matter) parameters. The data collected help improve mango fruit′s post-harvest management practices, to provide a product with constant quality and homogeneity to the consumer.

Gender Participation

The study was undertaken to examine the extent of women along with men participated in post-harvest activities; to identify the problems and constraints faced by them and find suitable solution from their perception. The post-harvest activities were estimated at farm level in Aman rice at Rangpur, Nilphamari, Khulna, Satkhira and Jessore district of Bangladesh by using survey data collected randomly from 270 rice growing households for the year 2012-13. It employed participatory approaches to investigate farmers’ perceptions on post-harvest management. The analyses shows women spends more time (591 hours ha-1) on PH activities than men (581 hours ha-1) but the ultimate decision maker of those activities are male indicating that women are very seldom given the opportunities to implement their ideas for execution although they are now gaining the right to give their opinion because of social awareness.J.

Rot Disease

Background: The post-harvest tomato fruit rot disease is common threat to the tomato fruit, causing huge economic loss as revealed by (GOP, 2018). The present study was conducted for isolatation and identification of causative agent of tomato fruit rot in order to formulate the proper management stretegies. Methods: Study was conducted in three phases. Phase one included collection of tomato fruit samples from vicinity of Tandojam. In phase two pathogens were isolated from the samples at laboratory, while in the phase three pathogens were identified using standard procedures. Result: The experimental results indicated Alternaria solani as the main cause of post-harvest tomato fruit rot. The symptoms observed were presence of brown to black rot lesions on tomato fruits with distinct rings ranging from small pin-heads to whole surface of fruit. A total of six different fungi viz., Alternaria alternata, Aspergillus niger, Alternaria solani, Geotrichum candidum, Fusarium oxysporum and Rhizopus stolonifer were found to be associated with post harvest tomato rot. Significantly higher infection was recorded for A. solani (53.667%) followed by A. niger (16.333%) and G. candidum (13.00%). The lowest infection percentage was observed for F. oxysporum (2.333%), followed by A. alternata (4.00%) and R. stolonifer (9.00%). A. solani produced aerial mycelium with yellowish to reddish diffusible pigments. A. niger cultures were typically black and colonies were initially whitish to yellow and later became brown to black in colour. G. candidum produced white and nonaerial colonies. F. oxysporum produced circular, aerial mycelium initially white, later changed to light pink. R. stolonifer produced whitish to grey fuzzy colonies.
