“…5). This result suggested effective biological control of soilborne pathogens, especially A. rolfsii should be at the initial stage of pathogen growth, as reported by Qadri et al (2020). In contrast, controlling A. rolfsii in the mycelial stage was partially successful when using only vermicompost (Fig.…”

Importance of the work:Vermicompost is utilized as biofertilizer, especially in organic farming systems. It has potential for soilborne plant disease control but empirical studies are scarce. Objectives: To test the effect of vermicompost from African nightcrawler in combination with Trichoderma asperellum isolate T13 on the mycelial growth of Athelia rolfsii in vitro and the incidence of sclerotium rot disease on vegetable soybean seedlings under greenhouse conditions. Materials & Methods: Fungal confrontation assay using either vermicompost filtrate or in combinations with varied spore concentrations of T. asperellum isolate T13 was conducted to observe antagonistic activity against the mycelial growth of A. rolfsii in vitro. Vegetable soybean seeds were sown in the greenhouse in soil mixed with vermicompost and pathogen inoculum (mycelia or sclerotia) to observe the disease incidence on the seedlings. Results: For the in vitro bioassay, adding half the proportion of T. asperellum isolate T13 spores (1 × 10 8 spores/mL) relative to the total volume resulted in 80.4% inhibition of A. rolfsii diameter growth, producing the best antagonistic activity. Under greenhouse conditions, the soil amended with mycelial inoculum and pure vermicompost led to significantly lower disease incidence (19.7%) than for the pathogen-inoculated control (40.7%) and the mixture of vermicompost and T. asperellum isolate T13 (34.7%). However, no disease incidence was observed with soil amendment using vermicompost, T. asperellum isolate T13 and sclerotia. Main finding: Vermicompost can be used as a bioagent for soilborne disease control, especially when combined with T. asperellum isolate T13, suggesting a strategy to prevent sclerotium disease incidence rather than trying to control actively growing mycelia.

Curvularia trifolii is an important pathogenic fungus that causes leaf spot disease in strawberry and other crops. Increased resistance in pathogenic fungi against chemical fungicides necessitates the search for biological alternatives to control plant fungal diseases. The present study aimed to perform transcriptome and metabolome analysis of C. trifolii fungi. We evaluated the potential of an alkaloid, namely alpha (α)-solanine, to inhibit the growth of Curvularia under in vitro conditions. Furthermore, transcriptomic and metabolomic analysis of treated C. trifolii was performed to identify the differential genes and metabolites. Results revealed that treatment with α-solanine resulted in the poor growth and development of fungal spores. The transcriptome analysis revealed that 1413 genes were differentially expressed (DEGs), among which 340 unigenes were up-regulated, 100 unigenes were down-regulated, and the rest were unaffected in treated samples. Gene ontology analysis revealed that the majority of the genes were related to oxidative stress in the fungus. Additionally, using ultra-high performance liquid chromatography-tandem mass spectrometry, we identified 455 metabolites, among which the majority of metabolites were related to lipid biosynthesis. The high number of genes related to lipid biosynthesis and reactive oxygen species revealed that α-solanine causes oxidative stress in Curvularia, leading to growth inhibition, and can be potentially used as an alternative to chemical fungicides.

The most important factors leading to high losses are their perishable nature, microbial decay, and diseases caused by microbial pathogens, resulting in qualitative and quantitative losses and consequently economic losses. , …”

Fungi are responsible for the majority of postharvest diseases of fruits, which cause large postharvest losses. Active films are promising delivery systems for ingredients with bioactive properties, allowing for the improvement of food quality and safety. The present study aimed at producing essential oil of Chenopodium ambrosioides (EOCA), as well as developing active films incorporated with different concentrations of EOCA (0, 100, 200, 300, and 400 g kg–1). EOCA increased the films’ opacity, solubility, and extensibility while decreasing rigidity, resistance, and permeability to water vapor. Cellulose acetate provides a slight thermal stabilization of the EOCA. The active films were effective against the phytopathogens Fusarium oxysporum and Colletotrichum gloesporioides in the vapor phase. The active films containing EOCA were successfully obtained, and, according to the results, we can emphasize the potential application of the films developed as active food packaging, highlighting the postharvest preservation of fruits and vegetables.
