“…Thus, in recent years, emergent sustainable and eco-friendly products/formulations to manage plant diseases have been evaluated [11][12][13]. For example, the application of plant extracts/essential oils (EOs), silicates and microbial metabolites that are capable of inducing plant's resistance when applied to the leaves have been reported [14,15].…”

Satureja montana Essential Oil, Zein Nanoparticles and Their Combination as a Biocontrol Strategy to Reduce Bacterial Spot Disease on Tomato Plants

Tomato bacterial spot (Bs), caused by Xanthomonas spp., including X. euvesicatoria (Xeu) remains a major threat for tomato production. The emergence of copper resistance strains of Xeu calls urgently for eco-friendly phytosanitary treatments as sustainable green alternatives for disease control. Satureja spp. essential oil (EO) has antimicrobial activity against xanthomonads and combined with zein nanoparticles (ZNPs), might offer a viable option for field applications. This study aims to evaluate the effects of S. montana EO, of ZNPs, and their combination in a nanoformulation, on Xeu quantity, and how these compounds modulate molecular and physiological changes in the pathosystem. Uninfected and infected tomato plants (var. Oxheart) were treated with EO; ZNPs and nanoformulation (EO + ZNPs). Treatments reduced Xeu amount by a minimum of 1.6-fold (EO) and a maximum of 202-fold (ZNPs) and improved plants’ health. Nanoformulation and ZNPs increased plants’ phenolic content. ZNPs significantly increased GPX activity and reduced CAT activity. Overall treatments upregulated transcripts of the phenylpropanoid pathway in infected plants, while ZNPs and nanoformulation upregulated those transcripts in uninfected plants. Both sod and aao transcripts were downregulated by treatments in infected plants. These findings demonstrate that S. montana EO, ZNPs and their nanoformulation are suitable to integrate tomato bacterial spot management strategies, mainly due to their antimicrobial activity on Xeu, however further field studies clarifying the long-term action of these products are required. These results also support the prophylactic potential of ZNPs on tomato bacterial spot.

Quinoa saponins are pentacyclic triterpene compounds composed of one triterpenoid glycoside and two different sugar chains. Previous studies have showed that natural quinoa saponins showed little or no antifungal activity, and there are few reports about their antifungal effects in recent decades. Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici (FOL) is the most serious for tomatoes in the field and under greenhouse conditions. The main objective of this study was to investigate the effectiveness of different concentrations and application modes of crude saponins from quinoa bran against the causal pathogen of tomato wilt under a greenhouse experiment. The results showed that the anti-FOL activity of quinoa saponins was weak in vitro, but significantly enhanced in vivo. Tomato seeds and seedlings treated with solution of quinoa saponins at 0.5 and 1.0 g/L significantly reduced the disease incidence (%) of tomato Fusarium wilt. The treatment types of saponin solution have influence on the preventive effects (%) of tomato seedlings against Fusarium wilt, among them, root soaking > foliar spray > seed soaking. The treatment of seed soaking with quinoa saponins inhibited germination of tomato seeds to some extent. However, the germination rate of tomato seeds after saponin soaking was comparable to the chemical pesticide (thiram carboxin); therefore, it could be used to control tomato wilt disease. This is due to the fact that the antifungal activity of quinoa saponins in vivo was much higher than that in vitro when the saponin concentration was between 0.5–1.0 g/L, indicating that the antifungal activity of quinoa saponins may be achieved mainly by inducing resistance. This investigation supports the potential use of quinoa saponins as a supplier of antifungal compounds, and could be the foundation for a future study examining the use of quinoa bran as a new resource against FOL.

“…The genus Albizia is one of 770 genera found in the third-largest angiosperm Fabaceae family and belongs to the Mimosoideae sub-family [18,19]. It is estimated that more than 150 plant species are categorised as members of the genus Albizia with a wide range of global distribution in tropical and subtropical regions of Africa, Asia, Australia, and the Americas [20,21]. Across West Africa, trees and shrubs of the genus Albizia are widespread in Ghana, Nigeria, Senegal, and The Gambia [22].…”

Traditional medicine is being revalued all around the world because of considerable research on various plant species and their therapeutic properties. Traditional medicinal beliefs and practices are deeply rooted in The Gambia, and forest resources are a source of plants for medicine. A study has estimated the presence of one hundred and fifty ( 150) plant species in The Gambia, distributed between 28 different plant families. Among the plant species, Albizia seems to possess numerous pharmacological properties. Albizia plants are high in secondary metabolites, according to phytochemical investigations, and pharmacological tests of plant extracts have demonstrated antibacterial, anti-inflammatory, and analgesic effects. Albizia plant components are used in traditional medicine to cure a variety of diseases like lung infections, asthma, pile, diarrhea, gonorrhea, ulcers, hemorrhoids, anxiety, depression, and insomnia. Different solvent extracts of the genus Albizia have demonstrated excellent efficacy against S
