“…Indirect approaches involve the application of mineral and organic fertilisers (Messiha et al 2021 ) or the adoption of biological soil disinfestation (BSD) which creates anaerobic soil conditions to impede phytopathogen proliferation (Blok et al 2000 ; Messiha et al 2007 ). Furthermore, previous research has explored the use of natural antioxidant producers to manage brown rot disease by inducing plant systemic resistance and enhancing soil health indices (Seadh and El-Metwally 2015 ; Farag et al 2017 ; Messiha and Elhalag 2019 ; Messiha et al 2021 ). The implementation of good agricultural practises is critical in the context of sustainable management.…”

“…Enhancing the soil suppressiveness by improving soil fertility indicators, such as available soil macronutrients (NPK), organic matter (OM%), and organic nitrogen (ON%)has been proven to be an effective and sustainable strategy for controlling disease in potatoes (Messiha 2006 ; Messiha and Elhalag 2019 ). Furthermore, promoting soil microbial biodiversity and increasing the ratio of antagonistic bacteria, such as fluorescent Pseudomonads , have been shown to significantly suppress R. solanacearum infecting potatoes (Messiha et al 2019 ).…”

Background Ralstonia solanacearum causes potato brown rot disease, resulting in lower crop’s production and quality. A sustainable and eco-friendly method for controlling the disease is required. Algae’s bioactive chemicals have shown the potential to enhance plant defenses. For the first time, the efficacy of foliar application of Acanthophora spicifera and Spirulina platensis seaweed extracts, along with the utilization of dried algal biomasses (DABs) of Turbinaria ornata and a mixture of Caulerpa racemosa and Cystoseira myrica (1:1)on potato yield and brown rot suppression were investigated under field conditions. Field experiments were conducted in three locations: Location 1 (Kafr Shukr district, Kaliobeya governorate), Location 2 (Moneira district, Kaliobeya governorate), and Location 3 (Talia district, Minufyia governorate). Locations 1 and 2 were naturally infested with the pathogen, while location 3 was not. The study evaluated potato yield, plant nutritive status and antioxidants, soil available nitrogen-phosphorus-potassium (N-P-K), and organic matter percentage. Additionally, the shift in soil microbial diversity related to R. solanacearum suppression was examined for the most effective treatment. Results The results revealed that seaweed extracts significantly increased potato yield at all locations, which correlated with higher phosphorus absorption, while T. ornate DAB increased potato yield only at location 2, accompanied by noticeable increases in soil nitrogen and plant phosphorus. The mixed DABs of C. racemosa and C. myrica demonstrated greater disease suppression than foliar applications. The disease-suppressive effect of the mixed DABs was accompanied by significant increases in flavonoids and total antioxidant capacity (TAC). Moreover, the application of mixed DABs increased soil bacterial biodiversity, with a higher abundance of oligotrophic marine bacterial species such as Sphingopyxis alaskensis and growth-promoting species like Glutamicibacter arilaitensis, Promicromonospora sp., and Paenarthrobacter nitroguajacolicus in all three locations compared to the untreated control. Klebsiella sp., Pseudomonas putida, and P. brassicacearum abundances were increased by the mixed DABs in Location 1. These species were less abundant in locations 2 and 3, where Streptomyces sp., Bacillus sp., and Sphingobium vermicomposti were prevalent. Conclusions The results demonstrated that the used seaweed extracts improved potato yield and phosphorous absorption, while the mixed DABs potentially contributed in disease suppression and improved soil microbial diversity.

“…The use of low susceptible cultivars to the infection by soilborne plant pathogens as well as the biological control have been extensively reviewed by several authors (Youssef, 2007). Application of organic amendments is an effective measure for controlling many soil-borne diseases (Abd El-Ghafar et al, 2004;Hagag et al, 2015 andElhalag, 2019) Bacterial wilt in tomato was suppressed using the poultry and farmyard manure and higher microbial activity was likely responsible (Islam and Toyota, 2004).…”

The efficacy of using Bion, two commercial bio-products and organic amendments on reduction of potato brown rot and assessment of the susceptibility of eight potato cultivars to the disease were evaluated. Field experiments during 2019/20 and 2020/21 growing seasons at Giza governorate, Egypt revealed that all the tested treatments effectively reduced the bacterial wilt under the natural infection. The combination treatments of Bion + Bio-ARC + Bio-Zeid and Bio-ARC + old Balady manure + chicken manure were the highly efficient ones in lowering the infection, being 2.3% wilt, 1.9% infected tubers and 2.0% wilt, 1.4% infected tubers, respectively. Additionally, Mondial potato cultivar was the least susceptible one associated with high rhizospheric microflora content. Using the combination of the resistance inducer Bion (BTH) with two commercial bio-products (Bio-ARC and Bio-Zeid) and two organic manures (Balady and chicken) are promising alternative methods for reducing potato bacterial wilt. Besides, there were remarkable variations in the values of free, conjugated and total phenols of the tested 8 potato cultivars, where Mondial cultivar recorded the highest values, Spunta the lowest values and the other cultivars recorded intermediate values.
