“…In this context, the possible use of NA has become an interesting alternative. There are many reports describing the antifungal properties of countless NA, including plant extracts, essential oils, or substances from different sources, such as chitosan or propolis (27)(28)(29). All of the NA tested in this work exhibited, although to various degrees, in vitro antifungal activity against the pathogens tested.…”

Grapevine trunk fungal pathogens, such as Diplodia seriata and Phaeomoniella chlamydospora, can infect plants through pruning wounds. They cause grapevine trunk diseases and are involved in grapevine decline. Accordingly, the protection of pruning wounds is crucial for the management of grapevine trunk diseases. The efficacy of different natural antifungals in inhibiting the growth of several fungi causing grapevine trunk diseases was evaluated in vitro. The fungi showing greater in vitro efficacy were tested on autoclaved grape wood assays against D. seriata and P. chlamydospora. Based on results from these assays, chitosan oligosaccharide, vanillin, and garlic extract were selected for further evaluation on pruning wounds inoculated with D. seriata and P. chlamydospora in field trials. A significant decrease in plant mortality was observed after 2 years of growth in the plants treated with the different natural antifungals compared to the mortality rate observed in infected plants that were not treated with antifungals. Also, the infection rate for the inoculated pathogens was significantly reduced in plants treated with the selected natural antifungals. Therefore, natural antifungals represent a promising alternative for disease control and could provide significant economic benefits for the grape-growing industry. Grapevine trunk diseases are a major threat to the wine and grape industry. They have been reported in most grapevineproducing regions worldwide, causing serious economic losses due to a significant reduction of both yields and the quality of the grapes (1-3). The diseases include Botryosphaeria dieback, esca, Eutypa dieback, Petri disease, black foot, and Phomopsis dieback as the most relevant pathologies.Planting material produced in nurseries is frequently infected with fungal pathogens, especially those involved in Petri and black foot diseases (4, 5). In mature vineyards, pathogens such as Ilyonectria sp. mainly penetrate through the root system (6). However, it is widely accepted that for many pathogens, the annually produced pruning wounds are the main route of entry into young and adult plants (7-9). Consequently, numerous studies have been conducted to assess the susceptibility of pruning wounds to fungal pathogens causing trunk diseases. Susceptibility to Botryosphaeriaceae species has been studied by several authors (8-10). Eutypa lata infection has been extensively analyzed by authors like Munkvold and Marois (11) (8) also studied susceptibility to Phomopsis viticola infection. All of these studies support the hypothesis that pruning wounds are the main route of entry of these pathogens in the plant, and, therefore, the development of measures to protect pruning wounds would be an essential tool in the management of vineyards with better sanitation. Accordingly, numerous tests treating pruning wounds with chemical fungicides and/or biological control agents (BCA) have been carried out. Munkvold and Marois (16) checked the efficacy of natural epiphytes and colonizers of pruning wounds fo...

“…Unfortunately, many chemical fungicides have various drawbacks in terms of toxicity and efficacy, and concerns have been raised about both their environmental impact and the potential health risk associated with their use (27). Accordingly, in recent years, public pressure to reduce the use of synthetic fungicides in agriculture has increased.…”

“…These chemicals were synthesized as a variety of bioactive compounds in plant tissues as natural product that has broad spectrum of activities against organisms, such as bacteria, fungi, tyrosinase enzyme and brine shrimp larvae. Each of the secondary metabolite has a variable mechanism of action, for example, the toxicity of polyphenols in microorganisms is attributed to enzyme inhibition by oxidation of the compounds [1] . However, the development of resistant strains of pathogenic bacteria [2] and fungi [3] to antibiotics, as well as the involvement of tyrosinase enzyme in melanin production which might be responsible for some of the histopathological features exclusive to skin disorders [4] , motivated our investigation for the bioactivity potentials of Bauhinia rufescens (B.…”

Resumen. La Sigatoka Negra es la enfermedad más destructiva del área foliar de plátanos y bananos. La incrementada resistencia del patógeno, y la contaminación provocada por los fungicidas químicos, han guiado a la búsqueda de alternativas para su control. El objetivo del trabajo fue determinar el efecto de la combinación de los extractos de ajo (Allium sativum) y clavo (Syzygium aromaticum) en Abstract. Black Sigatoka is the most destructive disease of the leaves of bananas. The increased resistance of the pathogen and the contamination caused by chemical fungicides have guided the search for control alternatives. The objective of the work was to determine the effect of the combination of extracts of garlic (Allium sativum) and clove (Syzygium aromaticum) in the development of Mycosphaerella fijiensis. The phytopathogen was grown in potato-dextrose-agar (PDA) media added with different concentrations of extracts. A factorial design of two factors at four levels was established. At higher concentration of garlic extract, less capacity to inhibit M. fijiensis colony. In contrast, the clove extract showed greater inhibition capacity at the higher concentration. The greatest inhibition of the growth, 39.6%, was with the mixture of 150 mg of garlic extract·ml -1 and 36 mg of clove extract·ml -1 . Effect of alcoholic extracts of garlic (Allium
