“…This pathogen is globally distributed and has enormous commercial importance due to its prevalence in the field as well as under storage conditions. It has been reported every year on different crops and is increasing at an alarming rate, and has recently been identified in potatoes ( Sepehrnush et al, 2018 ; Riaz et al, 2022 ).…”

“…The most important fungal diseases causing loss of potato production under field conditions and in storage have been the focus of constant effort by Phyto-pathologists attempting to prevent severe yield reductions. Specifically, N. rubicola is becoming a pathogen of interest in potatoes as it has been reported to cause losses of up to 20% yield during production ( Riaz et al, 2022 ). Despite current reports on this pathogen its promiscuity among crop species makes it even more alarming.…”

“…Potato tubers have a delicate outer flesh which facilitates post-harvest entrance of pathogens, particularly when injured. N. rubicola in the presence of high relative high humidity in the field and during the periods of harvesting negatively influences tuber storage ( Riaz et al, 2022 ). Hence, potato tubers stored at high humidity become susceptible to microbial attack that causes high production losses and poor nutritional quality of the potatoes ( Wasilewska-Nascimento et al, 2020 ).…”

“…Potato tubers during stem rot infection, undergo numerous biochemical changes that induce biosynthesis of phenolic acids which then converts into lignin or cross-linked cell walls ( Chourasia et al, 2021 ). Association and aggressiveness of N. rubicola rot to plants differs between geographic regions including climatic conditions and location of a field ( Riaz et al, 2022 ). Neocosmospora rubicola spores remain viable in the soil and on infected potato debris for a long period in the absence of a host plant.…”

“…This fungus symptomatically causes stunted growth, yellowing of leaves and typical grayish-black streaking on stems, roots, and tubers. With the spread of pathogen infection, potato plants progressively wilt and then die, causing huge economic losses to the farmers ( Riaz et al, 2022 ).…”

Potato (Solanum tuberosum L.) is one of the most important crops in maintaining global food security. Plant stand and yield are affected by production technology, climate, soil type, and biotic factors such as insects and diseases. Numerous fungal diseases including Neocosmospora rubicola, causing stem rot, are known to have negative effects on potato growth and yield quality. The pathogen is known to stunt growth and cause leaf yellowing with grayish-black stems. The infectivity of N. rubicola across a number of crops indicates the need to search for appropriate management approaches. Synthetic pesticides application is a major method to mitigate almost all potato diseases at this time. However, these pesticides significantly contribute to environmental damage and continuous use leads to pesticide resistance by pathogens. Consumers interest in organic products have influenced agronomists to shift toward the use of biologicals in controlling most pathogens, including N. rubicola. This review is an initial effort to carefully examine current and alternative approaches to control N. rubicola that are both environmentally safe and ecologically sound. Therefore, this review aims to draw attention to the N. rubicola distribution and symptomatology, and sustainable management strategies for potato stem rot disease. Applications of plant growth promoting bacteria (PGPB) as bioformulations with synthetic fertilizers have the potential to increase the tuber yield in both healthy and N. rubicola infested soils. Phosphorus and nitrogen applications along with the PGPB can improve plants uptake efficiency and reduce infestation of pathogen leading to increased yield. Therefore, to control N. rubicola infestation, with maximum tuber yield benefits, a pre-application of the biofertilizer is shown as a better option, based on the most recent studies. With the current limited information on the disease, precise screening of the available resistant potato cultivars, developing molecular markers for resistance genes against N. rubicola will assist to reduce spread and virulence of the pathogen.

Background The soil biota consists of a complex assembly of microbial communities and other organisms that vary significantly across farming systems, impacting soil health and plant productivity. Despite its importance, there has been limited exploration of how different cropping systems influence soil and plant root microbiomes. In this study, we investigated soil physicochemical properties, along with soil and maize-root microbiomes, in an agroecological cereal-legume companion cropping system known as push–pull technology (PPT). This system has been used in agriculture for over two decades for insect-pest management, soil health improvement, and weed control in sub-Saharan Africa. We compared the results with those obtained from maize-monoculture (Mono) cropping system. Results The PPT cropping system changed the composition and diversity of soil and maize-root microbial communities, and led to notable improvements in soil physicochemical characteristics compared to that of the Mono cropping system. Distinct bacterial and fungal genera played a crucial role in influencing the variation in microbial diversity within these cropping systems. The relative abundance of fungal genera Trichoderma, Mortierella, and Bionectria and bacterial genera Streptomyces, RB41, and Nitrospira were more enriched in PPT. These microbial communities are associated with essential ecosystem services such as plant protection, decomposition, carbon utilization, bioinsecticides production, nitrogen fixation, nematode suppression, phytohormone production, and bioremediation. Conversely, pathogenic associated bacterial genus including Bryobacter were more enriched in Mono-root. Additionally, the Mono system exhibited a high relative abundance of fungal genera such as Gibberella, Neocosmospora, and Aspergillus, which are linked to plant diseases and food contamination. Significant differences were observed in the relative abundance of the inferred metabiome functional protein pathways including syringate degradation, L-methionine biosynthesis I, and inosine 5'-phosphate degradation. Conclusion Push–pull cropping system positively influences soil and maize-root microbiomes and enhances soil physicochemical properties. This highlights its potential for agricultural and environmental sustainability. These findings contribute to our understanding of the diverse ecosystem services offered by this cropping system where it is practiced regarding the system's resilience and functional redundancy. Future research should focus on whether PPT affects the soil and maize-root microbial communities through the release of plant metabolites from the intercrop root exudates or through the alteration of the soil's nutritional status, which affects microbial enzymatic activities.
