“…Our work proved that F. tricinctum was the pathogen causing bulbs rotting and spalling from the basal disc, as well as progressive yellowing and defoliation of the leaves in lilies and Lanzhou lilies ( Li et al, 2013 ; Shang et al, 2014 ). Interestingly, we also found that F. tricinctum was involved in root rot of Chinese herbal medicine, e.g., Angelica sinensis and wolfberry ( Liu et al, 2021 ; Uwaremwe et al, 2022 ).…”

“…The biological activity of these strains is often related to the production of secondary metabolites, such as antimicrobial cyclic lipopeptides ( Dunlap et al, 2011 ). Our research shows that Bacillus amyloliquefaciens has good control effects on root rot infested by F. tricinctum in Chinese herbal medicine of Angelica sinensis , Lanzhou Lilies, and wolfberries ( Shang et al, 2016 ; Liu et al, 2021 ; Uwaremwe et al, 2022 ). B. amyloliquefaciens strains were found to inhibit F. tricinctum fungal mycelial growth, in vitro and in planta , as well as to promote the growth of seedlings ( Liu et al, 2021 ; Uwaremwe et al, 2022 ).…”

Plant pathogenic fungi such as Fusarium tricinctum cause various plant diseases worldwide, especially in temperate regions. In cereals, F. tricinctum is one of the most common species causing Fusarium head blight (FHB) and root rot. Infection with F. tricinctum results in high yield losses and reduction in quality, mainly due to mycotoxin contamination of grain. Mycotoxins produced by F. tricinctum, such as enniatins (ENs) and moniliformin (MON), which are the most studied mycotoxins, have been reported to have multiple toxic effects on humans and animals. Although chemical control of Fusarium infection has been applied to grains, it is not always effective in controlling disease or reducing the level of mycotoxins in wheat grains. To the contrary, chemical control may significantly increase infection of F. tricinctum in fungicide-treated plots after treatment. Our studies show that the bacterium Bacillus amyloliquefaciens, has good control effects against F. tricinctum. Therefore, its use as a biological control agent against various plant pathogens may be an effective strategy to control the spread of Fusarium pathogens. Here, we conduct a review of the literature involving this plant pathogen, its diversity, virulence, and methods to control.

“…Due to the absence of apparent symptoms in the early stages, there is a lack of adequate preventative methods for sugarcane root rot ( 3 ). It is traditionally managed using agricultural or chemical methods; however, these measures are often constrained by geographical limitations, labor unavailability, and seasonal considerations and are occasionally time-consuming ( 10 ). Moreover, controlling root rot via chemical approaches might result in soil deterioration, microbial drug resistance, and the presence of drug residues in crops ( 11 ).…”

Sugarcane is a critical sugar and bioenergy crop in China. However, numerous factors, including root rot disease, hamper its yield. Root rot disease is a severe agricultural issue, reducing yield and threatening sustainable crop production. The current study aimed to explore the fungal community structure, identify and characterize the primary pathogen for sugarcane root rot in Guangzhou, China. Eighty-nine samples of sugarcane root, stalk, rhizosphere soil, and irrigation water were collected from five sites in Guangzhou, China. Subsequently, 276 fungal strains were isolated to identify the primary pathogens. The five most common genera identified were Penicillium , Fusarium , Gongronella , Trichoderma , and Cladosporium. Fusarium was more prevalent in the infected soil samples than in healthy ones. Pathogenic assays of the strains revealed that the strain GX4-46 caused 80% of the disease. The strain was confirmed as Fusarium commune through phylogenetic and genome sequence analysis. Rhizosphere soil samples from different regional crops were collected to better understand the fungal community structure and the primary pathogen. We observed a significant presence of Fusarium in irrigation water, indicating that the root rot disease could originate from the irrigation water and then spread as a soil-borne disease. This research is pioneering and one of the most comprehensive investigations on the occurrence and prevalence of sugarcane root rot disease. This study will serve as a reference for expanding the sugarcane industry and a foundation for further exploration and control of root rot. IMPORTANCE Sugarcane, a significant economic crop, faces challenges due to root rot pathogens that accumulate each year in plants and soil through ratoon planting. This disrupts soil microbial balance and greatly impedes sugarcane industry growth. Symptoms range from wilting and yellowing leaves to stunted growth and reduced seedling tillers. The rhizosphere microbiota plays an important role in plant development and soil health. Little is known about root rot fungal community structure, especially in sugarcane. Here, we focused on exploring the main causative pathogen of root rot in the area alongside a detailed survey of the rhizosphere soil of different severity sugarcane cultivars and rotation crops of the region. To validate the findings, we also investigated the irrigation water of the area. Our study revealed Fusarium commune as the causative pathogen of root rot in the area, primarily originating from water and later as soil-borne. Using Trichoderma can control the disease effectively.

“…Several approaches are currently applied to control strawberry root rot, such as the breeding and selection of resistant cultivars, crop rotation, cultivation patterns, improved drainage and chemical plant protection, individually or combined [ 17 ]. The most common approach for the prevention and control of strawberry root rot is to use chemical fungicides, but strawberry fruits are consumed directly, and fungicide applications bring a range of issues such as the accumulation of toxin residue on the fruits, increased regulation, and negative impacts on the environment and human consumers, considering the increasing demand for sustainable agriculture [ 18 ]. Therefore, it is important to find a safer and more efficient biocontrol agent to control strawberry root rot.…”

Strawberry root rot caused by Fusarium solani is one of the main diseases of strawberries and significantly impacts the yield and quality of strawberry fruit. Biological control is becoming an alternative method for the control of plant diseases to replace or decrease the application of traditional chemical fungicides. To obtain antagonistic bacteria with a high biocontrol effect on strawberry root rot, over 72 rhizosphere bacteria were isolated from the strawberry rhizosphere soil and screened for their antifungal activity against F. solani by dual culture assay. Among them, strains CMS5 and CMR12 showed the strongest inhibitory activity against F. solani (inhibition rate 57.78% and 65.93%, respectively) and exhibited broad-spectrum antifungal activity. According to the phylogenetic tree based on 16S rDNA and gyrB genes, CMS5 and CMR12 were identified as Bacillus amyloliquefaciens. Lipopeptide genes involved in surfactin, iturin, and fengycin biosynthesis were detected in the DNA genomes of CMS5 and CMR12 by PCR amplification. The genes related to the three major lipopeptide metabolites existed in the DNA genome of strains CMS5 and CMR12, and the lipopeptides could inhibit the mycelial growth of F. solani and resulted in distorted hyphae. The inhibitory rates of lipopeptides of CMS5 and CMR12 on the spore germination of F. solani were 61.00% and 42.67%, respectively. The plant-growth-promoting (PGP) traits in vitro screening showed that CMS5 and CMR12 have the ability to fix nitrogen and secreted indoleacetic acid (IAA). In the potting test, the control efficiency of CMS5, CMR12 and CMS5+CMR12 against strawberry root rot were 65.3%, 67.94% and 88.00%, respectively. Furthermore, CMS5 and CMR12 enhanced the resistance of strawberry to F. solani by increasing the activities of defense enzymes MDA, CAT and SOD. Moreover, CMS5 and CMR12 significantly promoted the growth of strawberry seedlings such as root length, seedling length and seedling fresh weight. This study revealed that B. amyloliquefaciens CMS5 and CMR12 have high potential to be used as biocontrol agents to control strawberry root rot.
