“…The Jute leaf extracts significantly protected the treated potatoes against the soft rot development until 22 weeks under storage conditions (Rahman et al 2012). Aqueous plant extracts of Datura stramonium and Trigonella foenum graecum (seeds) and Azadirachta indica (leaves) inhibited the growth of E. carotovora in vitro tests (Viswanath et al 2018). Finally, these results are in agreement with the recent trend in shifting toward safer and more ecofriendly alternatives for controlling of postharvest decays, where the use of antagonistic micro-organisms is becoming popular throughout the world.…”

“…Soft rot bacterium can live as epiphyte and endophyte on plant debris or as saprophyte in soil. Then, the bacterium could penetrate the plant host through wounds or natural openings (Makhlouf-Abeer and Abdeen, 2014;Viswanath et al 2018). The bacterium can release enzymes of cellulase, protease, pectate lyase, polygalacturanase, and pectin-methylesterase which degrade the plant cell wall.…”

Background Application of chemical bactericides, for controlling soft rot bacteria, causes environmental pollution and toxic hazards to human. In addition, it is ineffective, expensive, and limited. Therefore, application of bio-control agents, plant extracts, or safe chemicals may play an important role as safe alternative approaches for controlling phyto-pathogenic bacteria. Objective This work is aimed to apply bio-control agents (Bacillus subtilis, Bacillus pumilus, Trichoderma harzianum, and Trichoderma virens), aqueous plant extracts (lantana flowers and leaves, lemongrass leaves, and olive cake), and citric acid as pre-sowing treatment for controlling bacterial soft rot pathogen and study their ability for improving yield and quality of potato tubers in field and storage. All treatments were applied as soil treatment and/or foliar spray, except citric acid applied as foliar spray only. Results The cultural filtrates of bio-control agents of B. subtilis, B. pumilus, T. harzianum, and T. virens; aqueous plant extracts of lantana, lemongrass, and olive cake; and citric acid could protect daughter potato tubers against bacterial soft rot disease in field application, except lemongrass (as soil treatment). The bio-control agents highly increased the activities of peroxidase, polyphenol oxidase, and chitinase enzymes, than other treatments. The bio-control agents also improved the shoot parameters, viz, shoot length, number of shoots/pit, and number of leaves/pit and yield parameters, viz, tuber weight/pit, tubers number/pit, and total tubers weight/pit, compared to citric acid and plant extracts, respectively. The treatments as foliar spray have good results for protecting the potato tubers through storage, than soil treatment. The treatments highly enhanced the stored potato tubers quality, viz, dry matter, reducing sugars, total carbohydrates, specific gravity, and starch content. Conclusions The tested treatments could protect the potato tubers in field and/or storage against soften development. The treatments could improve the plant growth and yield parameters in field as well as enhanced the stored potato tubers quality and increase the stored time. It is clear that the treatments can be applied as pre-sowing treatment for controlling Erwinia soft rot bacteria.

“…Potato is also one of the important food crops in India. India stands second in world's potato production where it is cultivated over an area of 2.13 million hectares with a production of 43.77 million metric tonnes (Viswanath et al, 2018) [11] . The area and production of the Potato crop in Jammu & Kashmir state are 6.9 thousand hectares and 1.27 lakh metric tonnes, respectively (Anonymous, 2015) [1] .…”

“…Like other antibiotics, a plant’s secondary metabolites encounter a barrier at the outer membrane of GNB, and limited efficacy is observed [ 108 ]. Nevertheless, many studies show C. sativa having a moderate to large inhibitory zone for Yersinia enterocolitica [ 79 , 83 , 107 ], Vibrio cholerae [ 73 ], Citrobacter freundii CCM 7187 [ 84 ], Erwinia carotovora [ 109 ], Bordetella bronchioseptica , Proteus vulgaris [ 105 ], Aeromonas hydrophyla , Beneckea natriegens , and Flavobacterium suaveolens [ 79 ].…”

Antimicrobial and Antiviral (SARS-CoV-2) Potential of Cannabinoids and Cannabis sativa: A Comprehensive Review

et al. 2021

Antimicrobial resistance has emerged as a global health crisis and, therefore, new drug discovery is a paramount need. Cannabis sativa contains hundreds of chemical constituents produced by secondary metabolism, exerting outstanding antimicrobial, antiviral, and therapeutic properties. This paper comprehensively reviews the antimicrobial and antiviral (particularly against SARS-CoV-2) properties of C. sativa with the potential for new antibiotic drug and/or natural antimicrobial agents for industrial or agricultural use, and their therapeutic potential against the newly emerged coronavirus disease (COVID-19). Cannabis compounds have good potential as drug candidates for new antibiotics, even for some of the WHO’s current priority list of resistant pathogens. Recent studies revealed that cannabinoids seem to have stable conformations with the binding pocket of the Mpro enzyme of SARS-CoV-2, which has a pivotal role in viral replication and transcription. They are found to be suppressive of viral entry and viral activation by downregulating the ACE2 receptor and TMPRSS2 enzymes in the host cellular system. The therapeutic potential of cannabinoids as anti-inflammatory compounds is hypothesized for the treatment of COVID-19. However, more systemic investigations are warranted to establish the best efficacy and their toxic effects, followed by preclinical trials on a large number of participants.
