“…Furthermore, F. oxysporum can cause 70% to 90% damage in infected tomato plants and up to 50% production losses (Jamil et al, 2021). The fungus damages plant tissues by blocking water and nutrient transportation in plants, ultimately resulting in permanent wilting and death (Hadiwiyono et al, 2020;Patel et al, 2022). Plants attacked by F. oxysporum appear wilted during the day, and the lower leaves of the plant turn yellow and wither at a later stage.…”

“…Fusarium infection is difficult to control because it is soil-borne, lives deep within the host tissue, and survives for extended periods (Bakker et al, 2020;Jamil et al, 2021). The pathogen, F. oxysporum can survive in the form of conidia for years and the spores can rapidly disseminate over large areas, causing an epidemic in plants (Patel et al, 2022). Prevention and control of F. oxysporum have generally been carried out through pest-resistant varieties, crop rotation and synthetic fungicides (Dukare and Paul, 2021).…”

Fusarium wilt is a plant disease caused by Fusarium oxysporum that generates significant economic loss to crops. A method to sustainably control F. oxysporum is utilizing biological agents, such as endophytic bacteria. Therefore, this study aimed to isolate endophytic bacteria from tomato plant tissue, which could inhibit the pathogen of wilt disease (F. oxysporum). Endophytic bacteria were isolated from local tomato plants in Muna Regency, Indonesia. Morphological characteristics such as size, shape, color and height of bacterial colonies were then determined by Gram staining using potassium hydroxide (KOH). Endophytic bacterial isolates were evaluated for their ability to inhibit F. oxysporum through inhibition and hydrogen cyanide (HCN) production tests. Subsequently, analysis of variance was used to determine whether endophytic bacteria inhibited F. oxysporum growth, and if there was a significant effect, Duncan's test was conducted at 95% significance. HCN production was observed through qualitative methods. The results showed that four endophytic bacteria isolates, namely LBR I A03, SWR II B04, SDM II B05 and SWR I A02 inhibited the growth of F. oxysporum by more than 50%. It also revealed that four endophytic bacterial isolates were strong HCN producers and two were weak producers. Therefore, isolates showing antifungal activity in this study can be used as biopesticide agents to induce plant resistance to F. oxysporum.

Aims Current understanding of how cropping sequence affects pathogen-suppressive microbiomes in soil is limited. We investigated the effects of several cropping sequences from the 2020–2021 growing seasons, including cereals, pulses, and an oilseed, on microbial communities in rhizosphere and bulk soils in two western Canadian field locations. Methods The fungi and bacteria were characterized by Internal Transcribed Spacer (ITS) and 16S rRNA gene sequencing, respectively. The QIIME 2™ bioinformatic pipeline was used to measure the diversity and abundance of microbial species. Additionally, the concentration of the soil mineral chemicals, including macro and micro nutrients, was determined by colorimetric analysis. Results Ascomycota (62.5%) was the most common fungal phylum, followed by Glomeromycota (11.1%), Mucoromycota (8.9%), and Basidiomycota (6.8%). Pseudomonadota (35.0%), Actinomycetota (21.1%), and Bacillota (10.1%) were the three most common bacterial phyla. Fungal OTU richness and phylogenetic diversity were highest in the cereal-pulse cropping sequencing, and bacterial OTU richness was highest in the pulse-oilseed sequences. Fusarium was the fungal genus most commonly associated with cereal-cereal monoculture and least common in the oilseed-pulse cropping sequences. The fungi (Mortierella, Funneliformis, and Diversispora) and bacteria (Rhizobium, Bradyrhizobium, Flavobacterium, and Candidatus) were higher in the cropping sequences involving pulses. The most prevalent bacteria were Streptomyces in cereal-related sequences and Solirubrobacter and Pseudomonas in oilseed-related sequences. Among soil mineral chemicals, nitrate-nitrogen, copper, calcium, potassium, and chlorine were associated with a number of beneficial fungal and bacterial genera but not with pathogenic fungal genera. Conclusions The results highlight the consequences of crop species selection in cropping sequences and the management of agrochemicals in the agricultural production system.
