Facing challenges from diseases that affect production, it is crucial to seek new strategies to maintain productivity and sustainability. Melaleuca alternifolia, known as the tea tree due to its medicinal properties, has little explored potential in controlling diseases in bean plants. The objective of this work was to evaluate the effectiveness of tea tree essential oil in controlling diseases in bean cultivation. In vitro tests were carried out to evaluate bacterial growth, at concentrations of (0.0%, 0.05%, 0.1%, 0.5%, 1% and 2%). And antibiogram with the bacteria Xanthomonas axonopodis pv. phaseoli, in different concentrations (0.0%, 0.05%, 0.1%, 0.5%, 1%, 2% and 3%). For the fungus Pseudocercospora griseola, sporulation tests were carried out, using direct and indirect methods, at concentrations of (0.0%, 0.05%, 0.1%, 0.5%, 1%, 2%, and 3%). Furthermore, for the fungus Colletotrichum lindemuthianum, mycelial growth tests were carried out with the same concentrations. The experiments took place in vivo, with a completely randomized statistical design, involving five replications per treatment and concentrations varying from (0.0%, 0.05%, 0.1%, 0.5%, 1% and 2%). Disease incidence was assessed using a diagrammatic scale, disease severity, Area under the Disease Progress Curve (AACPD) and Area under the Incidence Progress Curve (AACPI). Melaleuca Essential Oil (EO) inhibited the development of fungi and bacteria in in vitro tests starting at 0.5%. In vivo, Melaleuca Essential Oil (EO) showed a significant reduction in the incidence and severity of the disease from 0.5% in both fungi and bacteria. Melaleuca EO can be an effective alternative for disease control in bean cultivation.","PeriodicalId":93470,"journal":{"name":"Journal of plant science and phytopathology","volume":"115 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141834373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant leaves were extracted with two solvents (n-hexane and methanol). The phytochemicals were qualitatively and quantitatively analyzed using standard methods. The antioxidant activity was determined using DPPH. In the qualitative phytochemical screening of the methanol extract flavonoids, alkaloids, saponins, and tannins were identified as being present while steroids, anthraquinones, and glycosides were absent. All the screened secondary metabolites were absent in the n-hexane extract. In the GC-MS analysis of the methanol and n-hexane extracts seven compounds were obtained from the methanol extract while a total of twenty-four compounds were obtained from the n-hexane extract. The quantitative determination of the total flavonoid and phenolic contents showed that the leaves high content of flavonoids (91.00 mg quercetin equivalent/g extract) and phenolics (91.39 mg Gallic acid equivalent /g extract).

This study was carried out to assess the effect of whitefly infestation on the growth parameters of one of the commercial eggplant cultivars (round green Solanum melongena L) under filed conditions. The trial consists of four treatments (T1= 15, T2= 30, T3= 45 and control (T4) = 0 whiteflies/plot) replicated four times. The result revealed that all the parameters assessed are negatively affected by whitefly infestation with plants in treatment (T3) being most affected while those in T1 are least affected. The dry weight recorded least value (1.1 g/leaf) having the highest percentage reduction (69.11%) followed by leaf area with 152.5cm2 (48.83% reduction) while the number of leaves was least affected recording 50.3 leaves/plant (18.09% reduction) at 90 days after infestation in 2022 experiment. In 2023 experiment, similar results were recorded with plants in T3 being most affected. Dry weight of the leaves had the lowest value (1.3g/leaf) representing the highest reduction (68.30%) followed by the leaf area with 167.3cm2 (44.8% reduction) with the number of leaves also being least affected, recording 52.1 leaves/plant representing 9.40% reduction with plants in treatment T1, at 90 days after infestation. The highest reduction in yield was also recorded with plants in T3 (92.10, 90.10%) while the least was observed in T1 (86.8 and 85.70%) for the respective trials (2022 and 2023).

The growth regulatory activity of synthetic compounds Ivin, Methyur, Kamethur, and synthetic compounds, derivatives of pyrimidine (No. 1 - 7) was compared with the activity of auxins IAA (1H-indol-3-yl)acetic acid) and NAA (1-naphthylacetic acid).

Chocolate spot disease is a stress-related fungal disease produced by Botrytis fabae that causes plant damage, limits photosynthetic activity, and reduces yield. Results: Trichoderma atroviride greatly reduced mycelial growth by 90.00% in vitro, followed by T. harzianum (86.67%) and T. album (83.89%) on average. In vivo, all studied antagonists dramatically reduced Botrytis fabae disease incidence and severity in both seasons 2021/22 and 2022/23. T. atroviride showed the highest efficacy bioagent (73.55 and 85.15%), followed by T. harzianum (72.55 and 81.22%), in controlling B. fabae of faba bean plants in both seasons. In addition, the results also showed that all tested biological treatments had an impact on yield components and increased levels of chlorophyll, protein%, phenols, flavonoids, Peroxidase (PO), polyphenol Oxidase (PPO), chitinase, and -1, 3-glucanase activities compared to control treatment in both seasons. In this regard, spraying T. atroviride showed the highest efficacy as a bioagent, followed by T. harzianum. Contrary, T. hamatum showed the lowest efficacy compared to other treatments in both seasons. Conclusion: This investigation was carried out to determine the effectiveness of several different antagonists, i.e., T. album, T. atrovirde, T. hamatum, and T. harzianum (30 x 106 spore/ml), Blight Stop, and Bio Zeid, for controlling Botrytis fabae on bean plants and evaluating their effect on yield parameters, components, and quality.","PeriodicalId":93470,"journal":{"name":"Journal of plant science and phytopathology","volume":"339 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139012217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was determined that concentrations containing 0.1, and 0.25 ml essential oil showed no antifungal effects, however, concentrations containing 0.5 and 1 ml essential oil had antifungal effects. The most effective concentration was found to be 1 ml of essential oil in all three species. The maize was grown under hydroponic conditions. Thyme, ginger, and mint essential oils (1 g/100 ml) were applied to the root medium of the grown maize plant on the 8th day. An F. oxysporum suspension containing 107 spores was applied after 24 hours and harvested 3 days later. When the reactive oxygen species (H2O2) and MDA amounts of the harvested plants were examined, it was observed that there was an increase in the population of F. oxysporum. However, applications of thyme, ginger, and mint essential oil have been observed to significantly reduce these. It was also determined that essential oils protected the plant against F. oxysporum by increasing antioxidant enzyme activities.
