“…The identified antifungal properties were mainly attributed to compounds from the flavonoid group. Davari and Ezazi (2022) also reported an inhibitory effect of propolis ethanol extract against Fusarium sp.. Propolis produced by Africanized bees is currently being investigated for its antimicrobial action. Several studies suggest that the main compounds responsible for its antimicrobial activity are flavonoids and phenolic acid esters (Sforcin et Research, Society and Development, v. 11, n. 16, e445111638445, 2022(CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v11i16.38445 al., 2000Pietta et al, 2002).…”

The bees of the Meliponini tribe, known as stingless bees (SB), elaborate a distinct type of propolis, whose application potential is largely unexplored. Currently, there is some knowledge of the pharmacological activities of the propolis from Apis mellifera, however, little is known about the diversity and antimicrobial activity of Meliponini propolis, especially in relation to pathogens of agricultural importance. This study aimed to investigate the antimicrobial activity of the alcoholic extract of propolis from T. clavipes (Borá), S. bipunctata (Tubuna), and T. angustula (Jataí), comparing with the ethanolic extract from A. mellifera propolis. The autoclaved and non-autoclaved extracts were evaluated at the concentrations of zero, 1.6 %; 3.2 %; 6.4 %, and 12.0 % v/v. Fungal development was determined by measuring the mycelial diameter up to the fourteenth day of inoculation, with five replicates; the growth inhibition was calculated relative to the control. According to the results, the highest concentration of phenolic compounds and flavonoids was present in the ethanolic extract of A. mellifera propolis when compared to the SB extracts. The results indicated an inhibitory effect on the growth of the phytopathogens Colletotrichum gloeosporioides, Fusarium sp., Botryosphaeria sp., and Botrytis sp., mainly from 6.4 % and 12.0 % v/v when evaluated in the non-autoclaved medium, followed by the autoclaved medium. The fungus Botrytis sp. was the phytopathogen that suffered greater inhibition from 3.2 mL∙L-1, with the T. angustula propolis extract. The obtained results demonstrate that the alcoholic extracts of propolis from SB have the potential to control phytopathogenic fungi of agricultural interest.

“…More recently, new approaches have been evaluated, such as an enzymolysis pretreatment–MAE method [ 16 ] and microwave-assisted hydrodistillation (MAH) and extraction in situ by vegetable oil [ 17 ]. Other interesting alternatives that have been evaluated are propolis extract and the use of antagonistic fungi [ 18 ]. The search for ecological alternatives for the control of fungi that affect ornamental plants continues to be an area of interest for research.…”

Fusarium wilt, a vascular syndrome in a wide range of plants, is caused by the pathogen Fusarium Oxysporum. The objective of this investigation was to evaluate the antifungal effect of four essential oils (EOs) (Plectranthus amboinicus, Syzygium aromaticum, Lippia alba, and Rosmarinus officinalis), which were obtained by using microwave-assisted hydrodistillation (MAH), against F. oxysporum. The yield obtained from P. amboinicus with the use of MAH was 0.2%, which was higher than that of a conventional extraction; its extraction time was also shorter. For concentrations of 100 and 300 μL/L, P. amboinicus caused an inhibition rate of 27.2 and 55.7%, respectively, while S. aromaticum caused an inhibition rate of 23.1 and 87.3%, respectively. It was observed that increasing the concentration also increased the % inhibition rate. The extracts of L. alba and R. officinalis caused an inhibition rate of 14.5 and 14.7% at 500 µL/L, respectively, at 10 days of incubation, while at this concentration, P. amboinicus and S. aromaticum achieved 100%. The major chemical compounds of P. amboinicus were carvacrol (41.20%), o-cymene (11.61%), caryophyllene (11.45%), α-bergamotene (7.71%), and caryophyllene oxide (4.62%), and these monoterpene hydrocarbons were responsible for the biological activity. The essential oil of P. amboinicus in appropriate concentrations is a potent antifungal agent that could be used for the control of F. oxysporum.

“…Antagonistic potential is also seen against Fusarium spp. in mycelial inhibition (Davari & Ezazi, 2022) and further testing of biological management through in vitro and in planta under inoculated conditions (Hussain et al, 2016) revealed its efficiency as a biocontrol agent through enzymatic secretions that enabled cell wall degradation (Davari & Ezazi, 2022). Another study specifically involving Podosphaera xanthii, which causes powdery mildew, effectively controlled by Trichoderma spp.…”

Domestic production of tamarind has decreased in the country due to diseases. Tests were made on the individual efficacy of botanical extracts like plant growth promoter (PGP) and oriental herb nutrient (OHN), as well as the Trichoderma harzianum Rifai as a possible biocontrol agent against major fungal tamarind diseases. Using Randomized Complete Block Design (RCBD), a field setup was established with five treatments: untreated (negative control), synthetic fungicide, OHN, PGP, and T. harzianum having three replications per treatment. Results revealed that T. harzianum is an effective biocontrol agent against major fungal tamarind diseases. PGP having similar efficiency with T. harzianum significantly inhibited the infection and provided immediate defense from diseases. OHN is less effective due to delayed reduced infection. The research output is a significant help in the management of various diseases that is cost-effective and safe.
