... (E)-2-Hexenal is one of the most prevalent and abundant volatile substances in fruits. Many researchers have attempted fumigation with (E)-2-hexenal to control fungal diseases with poor or no results; the key is the inability to maintain an effective concentration for a long time. Therefore, a new starch-based antifungal coating with (E)-2-hexenal microcapsules was prepared. The obtained results s ...
... The present study focuses on antifungal potential of 1,2,4-triazole derivatives of allyl sulfides. The antifungal potential of synthesized 2-(allylthio)-1-(1'H-1',2',4'-triazol-1'-yl)ethanone (ATT) was compared with its diallyl analogue (a natural occurring) against Fusarium fujikuroito unveil its improved antifungal potential. The synthesized compound ATT had significantly better antifungal poten ...
... Bakanae disease of rice caused by Fusarium fujikuroi is a significant disease of rice worldwide. The use of inoculum free seeds works well to act against this seed borne disease. Increased restrictions by the environmental protection agency (EPA) on the use of chemical seed-dressing products have made this disease a major concern among seed producers. In the present studies, 1,2,4-triazole derivat ...

Abstract:
... An effective and greener method for the synthesis of 2-(phenyl)-4H-chromen-4-ones has been developed by reacting 2-hydroxychalcones and tert-butyl hydroperoxide (TBHP) in the presence of a base via ultrasonic irradiation. Ultrasonic irradiation is used to replace conventional energy sources in synthesis. In terms of energy conservation and waste reduction, ultrasonic irradiations are increasingly ...

... The development of new types of fungicides for agriculture and medicine is highly desirable due to the uprising fungal resistance against commonly used compounds. Herein, 4-substituted-4-nitropyrazolin-5-ones (nitropyrazolones) were proposed as highly active fungicides of the novel structural type. The first scalable and practical method for the nitropyrazolone synthesis was proposed, which is ato ...
... In this study, to increase the content of quercetin in the isolates obtained from the white and red onion scales, in accordance with the zero waste philosophy, using water as an environmentally and healthy friendly extractant, a mathematical model was constructed, based on the Central Composite Design. The suitability of the model for the accurate and quick study of complex relationships was demon ...
... Bread is a food that is commonly recognized as a very convenient type of food, but it is also easily prone to microbial attack. As a result of bread spoilage, a significant economic loss occurs to both consumers and producers. For years, the bakery industry has sought to identify treatments that make bread safe and with an extended shelf-life to address this economic and safety concern, including ...

... The present study aimed to evaluate the potential of the laminarin-based formulation Vacciplant to protect and induce resistance in wheat against Zymoseptoria tritici, a major pathogen on this crop. Under greenhouse conditions, a single foliar spraying of the product 2 days before inoculation with Z. tritici reduced disease severity and pycnidium density by 42 and 45%, respectively. Vacciplant exh ...
... Fusarium graminearum and Zymoseptoria tritici cause economically important diseases of wheat. F. graminearum is one of the primary causal agents of Fusarium head blight (FHB) and Z. tritici is the causal agent of Septoria tritici blotch (STB). Alternative control methods are required in the face of fungicide resistance and EU legislation which seek to cut pesticide use by 2030. Both fungal pathoge ...

Abstract:
... Ganoderma lucidum polysaccharide (GLP), which is the primary active ingredient in G. lucidum, has been widely used in functional food and clinical medicine. However, it is rarely reported in the prevention and control of plant diseases. In this study, we found that the GLP can increase the germination rates and seedling heights of maize and wheat. We also found that the combination of GLP and chem ...
... Spadix rot is an emerging disease of flamingo flowers (Anthurium andraeanum) that limits their commercial production. The biological control of spadix rot by Streptomyces, a rhizosphere bacterium, is a possible method for controlling this disease instead of the excessive use of chemical fungicides. This research aimed to screen actinobacteria with antifungal ability against Lasiodiplodia theobroma ...
... Screening for microorganisms with antagonistic activity against crop pathogens is essential for microbial antagonist preparation, crop disease control, and sustainable agricultural development. This study established a rapid, efficient, one-step high-throughput method for screening endophytic bacteria displaying antagonistic activity against Magnaporthe oryzae (M. oryzae) ACCC36020 in rice seeds. ...
... In this study, 15 strains of Lactic acid bacteria (Allata et al.) and 6 strains of propionic acid bacteria (PAB) were firstly tested for their antifungal activity against three spoilage fungi, Aspergillus niger, Penicillium crustosum and Aspergillus flavus. Two strains of LAB and PAB were selected and assessed, alone or paired, for their abilities to inhibit the most resistant mold, Aspergillus ni ...

... Entada abyssinica Steud. Ex A. Rich (Leguminosae) is a medicinal plant used traditionally for the treatment of infections. A phytochemical investigation of the methanol extract of E. abyssinica root bark led to the isolation of a new phenanthrene derivative named phenentada (1), together with seven known compounds (8 S, 13 E)-kolavic acid 15-methyl ester (2) and 8 S-kolavic acid 15-methyl ester (3 ...

... Plants encode specific class III peroxidases (POX) as large multigene families that are involved in lignification, cell elongation, stress defense, and seed germination. However, many functions associated with these plant enzymes are not fully understood. Here, a class III peroxidase (Vu-RPOX) was purified from cowpea (Vigna unguiculata) roots with 0–90% ammonium sulfate precipitation, chitin colu ...

METHODS AND RESULTS: The fungal growth was assessed following the optical density at 630 nm. Fungal cell morphology and nucleus integrity were analysed by flow cytometry and confocal laser scanning microscopy using ...
... In order to develop a strong, tough, water-resistant, and mildew-resistant soy protein film replacing petroleum-based films, in this study, a covalent and hydrogen bond double network structure was constructed in soy protein film using self-synthesized crosslinker triglycidylamine (TGA), soy protein (SPI), and poly(vinyl alcohol) (PVA). The covalent bond network from the crosslinking reaction betw ...
... Dextran has emerged as a promising biopolymer carrier for controlled release formulations of pesticides. In this study, pH-sensitive acetalated dextran microparticles (Pyr@Ac-Dex) are prepared to encapsulate and control the release of pyraclostrobin (Pyr). In vitro fungicidal activity experiments showed that the prepared Pyr@Ac-Dex particles show comparable fungicidal ability against S. sclerotior ...
... Soil pH conditions have important consequences for microbial community structure, their dynamics, ecosystem processes, and interactions with plants. Low soil pH affects the growth and functional activity of bacterial biocontrol agents which may experience a paradigm shift in their ability to act antagonistically against fungal phytopathogens. In this study, the antifungal activity of an acid-toler ...
... The loss of fresh produces owing to the microbial infestation is a major challenge to the global food industry. The drastic food loss caused mainly by the fungal attack demands the need for development of active packaging materials with antimicrobial properties. Many studies have already been reported on the applications of polymers like polyvinyl alcohol (PVA) engineered with antimicrobial compon ...
