“…The addition of these residues and by-products to agricultural soil could be used as substitutes for chemical fumigants and fertilizers. By using agrowaste as soil amendment has a positive impact on the organic matter content and fertility of soil, thereby improving health ( De Corato et al., 2024 ) and suppressiveness of the soil against various stress factors, including those caused by soil-borne plant pathogens ( De Corato, 2023 ).This benefit could be utilized by farmers to decrease the necessity of adding chemical fertilizers to the soil, promoting the use of organic residues as fertilizers.

The study explores anaerobic soil disinfection as an alternative to soil fumigants for controlling Verticillium wilt in strawberry crops. For this purpose, two agrowastes close to the strawberry-growing areas of Huelva province were tested as potential amendments for the control of Verticillium wilt: rice bran and residual strawberry extrudate. Furthermore, two application rates were evaluated: 13.50 and 20.00 t/ha for the rice bran and 16.89 and 25.02 t/ha for residual strawberry extrudate. Amended and anaerobically disinfested soils were compared with a non-amended soil under anaerobic conditions, a soil treated with the chemical fungicide metam sodium and an untreated soil. One week before the start of disinfection treatment, these soils were artificially inoculated with 250 microsclerotia/g dry soil of Verticillium dahliae. After disinfestation treatments, pathogens were quantified, and strawberry plants were cropped in a growth chamber to further evaluate Verticillium wilt severity, which was measured with a symptom scale in the same potting soils. Measurements of the anaerobic condition, pH and microbial population densities were performed, and the results showed significant differences between the different amendments. In addition, the treatment with rice bran at 20 t/ha recorded the lowest population density of V. dahliae. Likewise, it was possible to achieve a reduction in foliar disease severity in all amended treatments in similar percentage to those obtained by chemical treatment. These results suggest potential application of this technique for the control of Verticillium wilt in the strawberry-growing area of Huelva, reducing the use of chemical fumigants.

“…Saudi Arabia is one of 181 countries that strongly promote and adopt organic farming, to reduce water usage, save environments and alleviate negative consequences of chemicalbased agriculture (IFOAM, 2020). Application of organic matter such as compost and manure can improve soil quality by increasing water-holding capacity and organic content, along with maintaining exchangeable cations (Reeves, 1997;Etana et al, 1999;Balesdent et al, 2000;De Corato, 2023). A major challenge with implementing biocontrol strategies is how to maintain stable populations of biocontrol agents throughout crop growing seasons (Lewis and Papavizas, 1984;Waage and Greathead, 1988;Chammem et al, 2022).…”

A comprehensive understanding of population dynamics of pathogens and bioagents in plant rhizospheres is important for improving organic farming. Fusarium oxysporum f. sp. lycopersici (FOL30) causes Fusarium wilt of tomato. In this study, we compared biomass variations of FOL30 under different disease control regimes, using Trichoderma asperellum TA23 strain, compost, or their combination. Biomass variations of FOL30 and TA23 were observed for 13 weeks using quantitative real-time PCR. Separate applications of TA23, compost, and their combination all reduced FOL biomass when compared to experimental controls. Regression analyses of the qPCR data showed that FOL populations fitted curvilinear polynomial order 3 regression models (R2 = 0.87 to 0.95). Areas under the population dynamic curves (AUPDCs; log10 ng DNA week-1 g-1 soil) were: 43.8 from FOL30 alone, 36.6 from FOL30 plus TA23, 25.4 from FOL30 plus compost, and 25.5 from FOL30 plus TA23 plus compost. These results indicate that the individual applications of TA23 or compost, or their combination, decreased the FOL biomass. The negative correlation between TA23 and FOL30 populations showed that the compost and biocontrol agent reduced FOL pathogen populations. This study demonstrates that compost fortified with T. asperellum TA23 decreased FOL populations and reduced disease, and that their use is a promising strategy for managing Fusarium wilt of tomato in organic farming.

“…Organic matter in the soil increases the number of beneficial microbes which can interfere with the development of M. phaseolina. Soil amendments with crop wastes, biochar or compost promote soil health and plant defense (De Corato, 2023). Biochar is a charcoal type material, made by burning organic feedstock, e.g.…”

The present study focused on the management of charcoal rot of maize caused by Macrophomia phaseolina, by using biochar made from rice straw, along with compost and Trichoderma viride (Biocontrol agent). Therefore, synergistic effect of 3 and 6 % concentrations of rice straw biochar with T. viride and 10 % of compost was used as a soil amendment to check the effect on growth of maize and charcoal rot disease suppression under glasshouse conditions. The percentage severity of charcoal rot was significantly reduced due to the effect of soil amendment with 3 % rice straw biochar inoculated with or without T. viride. In vitro assays also revealed synergistic association of rice straw biochar with T. viride and resulted into maximum inhibition (69.67 %) of M. phaseolina. The maximum nitrogen contents (20.26 g/kg) were recorded in rice straw biochar (3 %) combined with biocontrol agent amended treatment. However, other than disease parameters, 6 % rice straw biochar irrespective to the presence or absence of T. viride had a significant impact on growth of maize plants. The maize response were found to be dependent on the concentration of biochar (3 and 6 %) and depicted varied effects of resistance in each treatments. Thus, our findings suggest that the combined application of biochar and T. viride holds significant potential for mitigating the detrimental effects of charcoal rot and enhancing the overall health and performance of maize plants.
