Evaluation of possible biological control of Fusarium sp. using plant extracts and antagonistic species of microbes in vitro

Abstract

Background: Fusarium species is one of the most devastating fungi responsible for fruit and vegetable crops rot worldwide. The present study was designed to find an ecofriendly control measure for pathogenic Fusarium species, using suitable bioagents. Methods: Medicinal plant extracts were evaluated or their antifungal activities against Fusarium species using the poisoned food method. Antagonistic potency of some nonpathogenic microbes was also assessed on Fusarium species using the dual culture method. Results: Highest inhibition of growth of Fusarium sp. was observed with 68.1% (0.389 mg per 90 mm Petri plate) of mycelia on Coccinia grandis plant leaf extract, in comparison to the control grown with 100.0% (1.22 mg/dish). The highest inhibition of radial growth was observed using Trichoderma viride on Fusarium sp. (46.01% inhibition). Conclusions: The findings of present study would be benevolent for antifungal drug development to control Fusarium sp. causing fruit and vegetable rot.

Enhancing the Potentiality of Trichoderma harzianum against Pythium Pathogen of Beans Using Chamomile (Matricaria chamomilla, L.) Flower Extract

“…Plant extracts are considered another alternative to traditional fungicides and pesticides as they produce bioagents that are effective against bacteria and fungi [ 20 ]. The volatile compounds and essential oils show promise as a substitute for antibacterial and antifungal agents in several studies [ 21 ].…”

Alternatives and low-cost strategies to control of pathogens in bean seeds: a review

“…From these disadvantages, antimicrobial characteristics have been sought in plants with intensified increase (Pushpavathi et al 2017). Since some plants have bioactive substances and are sources of resistance inducers El-sawy 2015;Zaker 2016;Hasan;Islam 2020), for the use of these active ingredients, several types of extraction can be used, such as aqueous, dry extract and oil extraction (Spadaro et al 2017).…”

Characterization of Rhizobium Isolates as Biocontrol Agents Against Fusarium Solani and Macrophomina Phaseolina

“…M. phaseolina is the chief cause of root rot disease in essential plants, such as, corn and cotton (Aly et al, 2007;Khaledi and Taheri, 2016). Fusarium is one destructive fungus that causes fruit and vegetable crop rot and is responsible for about 60-70% loss of fruit yield (Darmadi et al, 2019;Srinivas et al, 2019;Hasan et al, 2020). Ketta et al (2021) investigated the antagonism of R. leguminosarum combined with certain Trichoderma species against R. solani and F. solani, the primary sources of damping-off diseases in peas.…”

“…Moreover, other studies reported that Rhizobium isolates could inhibit the radial growth of F. oxysporum f. sp. ciceris and M. phaseolina in higher levels, as well as, improve each plant's growth and yield in vitro and the field (Arfaoui et al, 2006;Al-Ani et al, 2012;Hasan et al, 2020). The nifH is a well-known principal gene that encodes for one of the nitrogenase enzyme subunits (Rubio and Ludden, 2002).…”
