“…(Diallo et al, 2011;Raaijmakers et al, 2002). It has also been indicated that different combinations of taxa and the interactions between those taxa may be effective in combating plant pathogens and in the induction of resistance in the plant (Czajkowski et al, 2020).…”

Soft rot Pectobacteriaceae (SRP) are the causative agents of soft rot and blackleg in potato. In this study, we investigated if potato seed lots of the same cultivar, but originating from different fields, inoculated with the same density of SRP and planted in the same field, showed differences in blackleg disease incidence. We tested if these differences were correlated with the microbial community composition in tuber, and the soil where the mother tubers were grown, as the microbiome is known to play a large role in plant disease resistance. We found that tubers from seed lots with a high disease incidence had a different microbial community composition than tubers from seed lots with a low disease incidence. Several taxa could be identified that were on average more abundant in seed lots with a low disease incidence. However, the taxa that differed in abundance were different between the two growing seasons. Most of the taxa that differed in abundance between seed lots with high and low disease incidence were also present in the soil of the fields from which the tubers originated. However, the taxa did not differ in abundance between the different fields. This raises the question as to how these taxa are recruited by the tuber.

“…An important advantage of pathogen biological control based on microorganisms, especially their mixtures, is their ability to protect plants from diseases and promote plant growth [32,33]. This opens up the possibility of registering a microbial consortium as a biofertilizer, which often follows a more straightforward product registration method [34]. Biofertilizers that protect plants from diseases can encourage farmers to adopt biological approaches, especially those interested in conventional, sustainable or organic farming [35].…”

“…Therefore, this is why microbial consortia are commonly used as biofertilizers [151]. However, there are relatively few biocontrol products containing microbial consortia [34], not only due to the more problematic registration [152] of multiple-component-containing products but also to difficulties in the prediction of interactions between their components [153]. Microorganisms used for biocontrol usually produce a wide array of antimicrobial compounds, and the same modes of action used to fight the pathogens can negatively affect other consortium components [103].…”

“…There are various methods for assessing strain compatibility, each with its own advantages and disadvantages. However, the most commonly used approach to evaluate the biocompatibility of strains and their activity against selected pathogens relies on direct antagonism on artificial media [34]. Since microbial secondary metabolisms are highly dependent on the nutrients available [155], it has been suggested that strains for biological plant protection should be selected based on their in vivo rather than in vitro activity [156].…”

Biological plant protection presents a promising and exciting alternative to chemical methods for safeguarding plants against the increasing threats posed by plant diseases. This approach revolves around the utilization of biological control agents (BCAs) to suppress the activity of significant plant pathogens. Microbial BCAs have the potential to effectively manage crop disease development by interacting with pathogens or plant hosts, thereby increasing their resistance. However, the current efficacy of biological methods remains unsatisfactory, creating new research opportunities for sustainable plant cultivation management. In this context, microbial consortia, comprising multiple microorganisms with diverse mechanisms of action, hold promise in terms of augmenting the magnitude and stability of the overall antipathogen effect. Despite scientific efforts to identify or construct microbial consortia that can aid in safeguarding vital crops, only a limited number of microbial consortia-based biocontrol formulations are currently available. Therefore, this article aims to present a complex analysis of the microbial consortia-based biocontrol status and explore potential future directions for biological plant protection research with new technological advancements.

“…Biocontrols are typically sold and applied as single microbial inoculants. There is, however, an increasing interest in the delivery of consortiums of beneficial microbes to promote plant health ( Czajkowski et al, 2020 ). Studies on Sclerotinia are scarce, but there is evidence of the potential for this approach in disease control.…”

Tackling Control of a Cosmopolitan Phytopathogen: Sclerotinia

Phytopathogenic members of the Sclerotinia genus cause widespread disease across a broad range of economically important crops. In particular, Sclerotinia sclerotiorum is considered one of the most destructive and cosmopolitan of plant pathogens. Here, were review the epidemiology of the pathogen, its economic impact on agricultural production, and measures employed toward control of disease. We review the broad approaches required to tackle Sclerotinia diseases and include cultural practices, crop genetic resistance, chemical fungicides, and biological controls. We highlight the benefits and drawbacks of each approach along with recent advances within these controls and future strategies.
