“…Plants from each treatment were carefully uprooted and cleaned under running tap water 180 days after seeding. Thereafter, vegetative growth characteristics such as total fresh weight (gm), root weight (gm), root length (cm), and root diameter (cm) were assessed according to [ 35 ]. However, the sugar beet quality parameters (sucrose%, extractable sugar %, potassium %, α-amino nitrogen %, sodium %, and sugar loss to molasses %) were evaluated at Al-Fayoum sugar company laboratories.…”

Sugar beet root rot disease triggered by Fusarium oxysporum f. sp. radicis-betae is a destructive disease and dramatically affects the production and quality of the sugar beet industry. Employing beneficial microorganisms as a biocontrol strategy represents an eco-friendly and sustainable approach to combat various plant diseases. The distinct aspect of this study was to assess the antifungal and plant growth-promoting capabilities of recently isolated Streptomyces to treat sugar beet plants against infection with the phytopathogen F. oxysporum. Thirty-seven actinobacterial isolates were recovered from the rhizosphere of healthy sugar beet plants and screened for their potential to antagonize F. oxysporum in vitro. Two isolates SB3-15 and SB2-23 that displayed higher antagonistic effects were morphologically and molecularly identified as Streptomyces spp. Seed treatment with the fermentation broth of the selected Streptomyces strains SB3-15 and SB2-23 significantly reduced disease severity compared to the infected control in a greenhouse experiment. Streptomyces SB2-23 exhibited the highest protective activity with high efficacy ranging from 91.06 to 94.77% compared to chemical fungicide (86.44 to 92.36%). Furthermore, strain SB2-23 significantly increased plant weight, root weight, root length, and diameter. Likewise, it improves sucrose percentage and juice purity. As a consequence, the strain SB2-23’s intriguing biocontrol capability and sugar beet root growth stimulation present promising prospects for its utilization in both plant protection and enhancement strategies.

Background Safe food free from diseases is the world's goal. Excessive usage of chemical fungicides is considered the most important danger for the climate. Natural alternatives with low costs have become the best choice for sustainable agriculture. Results In the context of researching green materials instead of chemical fungicides, the fabrication of nano-Sargassum vulgare and its composite with zeolite was carried out. Followed by an investigation of the efficiency of their extracts on controlling sugar beet root rot diseases caused by soil-borne pathogens Rhizoctonia solani (R. solani), Sclerotium rolfsii (S. rolfsii), and Fusarium oxysporum (F. oxysporium) throughout two successive seasons (2020/2021 and 2021/2022) under greenhouse conditions. The structure and morphology of nanosargassum and its biocomposite were characterized by FTIR, SEM, EDX, Zeta potential, and size particles. The morphological structure of biocomposite was changed from tubularly structured into layers stacked on top of each other after impregnation of zeolite into S. vulgare, and its size was reduced from 85 to 50 nm, which was confirmed through size particle distribution. The biocomposite was the most effective one in managing root rot disease caused by R. solani. It reduces disease severity (DS) and disease incidence (DI) with efficacy (91.08% and 88.89%), respectively, compared to that recorded by commercial fungicides (63.09% and 61.81%). In the same manner, the composite extract recorded the highest efficiency percentage in controlling the disease caused by S. rolfsii (76.04 and 55.27e was carried out. followed by an investigation of the efficiency of their extracts on controlling sugar beet root rot diseases caused by soil-borne pathogens Rhizoctonia solani (R. solani), Sclerotium rolfsii (S. rolfsii), and Fusarium oxysporum (F. oxysporium) throughout two successive seasons (2020/2021 and 2021/2022) under greenhouse conditions.

In the same manner, the composite extract recorded the highest efficiency percentage in controlling the disease caused by S. rolfsii (76.04 and 55.27%), respectively, compared to fungicide (67.74 and 36.92%). All applied treatments considerably reduced DS and DI caused by F. oxysporum. At the same time, growth characteristics, sucrose, and TSS percentages of the root juice significantly improved when the seeds were treated with the biocomposite extract. Conclusion The newly fabricated structure of biocomposite facilitates the movement of macronutrients from the soil into the seed, which in turn improves growth characteristics and the sucrose yield quality in root juice, which is one of the most essential characters to advance the sugar industry. Therefore, the biocomposite is recommended to be a biofungicide and biofertilizer. Graphical Abstract
