“…In addition to this, soil drench with P. lilacinum resulted in significant improvement in plant growth parameters and increased the yield of potato by more than 37% compared with untreated plots. 56 The biocontrol agent should be compatible with other strategies of integrated pest management (IPM). Jacob et al 57 studied the compatibility of three nematophagous fungi, P. lilacinum, Plectosphaerella cucumerina, and P. chlamydosporia with commonly used chemical pesticides including three fungicides (tolclofosmethyl, pencycuron and fenpiclonil) and one nematicide (oxamyl).…”

“…Under field conditions, Umamaheswari et al 70 evaluated the effect of biocontrol agents (T. viride and P. fluorescens) and among the biocontrol agents, the treatment with P. fluorescens resulted in higher plant growth parameters and yield coupled with lower PCN multiplication in soil. Recently, Nagachandrabose 56 evaluated the liquid formulations of biocontrol agents and reported that P. fluorescens when applied as a seed treatment at 1 L t −1 of seeds resulted in a maximum (> 80%) reduction in egg density and multiplication rate of PCN under field conditions. Additionally, it also improved plant growth parameters and resulted in a 27-32% yield advantage over the untreated control.…”

Potato cyst nematodes (PCNs; Globodera spp.) are one of the most difficult pests of potato to manage worldwide. Indiscriminate use of pesticides and their hazardous effects discourage the use of many chemicals for the management of PCNs. As a result, biological control agents and trap crops have received more attention from growers as safer ways to manage PCNs. The biological control agents such as Pochonia chlamydosporia, Purpureocillium lilacinum, Trichoderma spp., Pseudomonas fluorescens, Bacillus spp., Pasteuria spp., and others are recognized as potential candidates for the management of PCNs. Moreover recently, the use of trap crop Solanum sisymbriifolium also showed promise by drastically reducing soil populations of PCNs. Integration of these management strategies along with other practices including identification, conservation, and multiplication of native antagonists, will facilitate efficient management of the PCNs in potato cropping system. Some of the promising research approaches that are being used against PCNs are addressed in this review. © 2022 Society of Chemical Industry.

“…This strain also produced indole-3-acetic acid (IAA), a plant hormone from the auxin group. Another fungus used in the experiments described in that work was Purpureocillium lilacinum (Nagachandrabose 2020). Although this fungus was mainly used to control parasitic nematodes, it became evident that it also had properties stimulating the growth of many plants, including tomato, bean, cotton, and banana (Lan et al 2017).…”

In recent years, the use of bio-fertilizers enriched with specially selected microorganisms has been used more and more often. The beneficial effects of bio-fertilizers enriched with consortia of microorganisms on strawberry plants have been reported previously. The purpose of the research was to determine the effect of bio-fertilizers containing selected fungal and bacterial strains on the microorganisms living in the rhizosphere of strawberry plants. In the experiments described in this paper, synthetic mineral fertilizers were enriched with selected microorganisms. The fertilizer urea was enriched with the fungi Aspergillus niger and Purpureocillium lilacinum, while the fertilizers Polifoska 6 and Super Fos Dar 40 with strains of the bacteria Bacillus sp., Bacillus amyloliquefaciens, and Paenibacillus polymyxa. Bacteria and fungi belonging to these species can exert a positive effect on the growth of many plants. The results obtained in this study showed that the application of fertilizers enriched with microorganisms had different effects on the analyzed populations of soil microorganisms in the rhizosphere of strawberry plants. There were evidences of both, an adverse effect of the applied fertilizer and/or microorganisms, but more often, the beneficial effect was found on the abundance of the microorganisms in the rhizosphere of the strawberry. The most effective for the population of Pseudomonas bacteria was application of urea and fungi and Polifoska and bacteria. The highest number of phosphorus utilizing bacteria B was scored in the treatments containing NPK, NPK + fungi and urea 60% + fungi. The application of NPK + fungi and urea 100% + fungi as well as Super Fos Dar with bacteria was most beneficial for population of actinomycetes.

“…One alternative to traditional agrochemicals is biocontrol, which depends on using natural microbial competitors against a variety of pathogens to restrict pathogens' growth and survival. Several biocontrol agents have been identified and found to show a broad range of activity against bacterial, fungal, viral, and nematode pathogens (Hansen & Keinath, 2013; Nagachandrabose, 2020; Sofrata et al, 2011; Wang et al, 2019). Plant growth‐promoting bacteria (PGPB) are one example of potentially highly effective biocontrol agents, with a broad‐range biocontrol activity (Pierson et al, 1998).…”

Combining in vitro and in vivo screening to identify efficient Pseudomonas biocontrol strains against the phytopathogenic bacterium Ralstonia solanacearum

Although plant pathogens are traditionally controlled using synthetic agrochemicals, the availability of commercial bactericides is still limited. One potential control strategy could be the use of plant growth‐promoting bacteria (PGPB) to suppress pathogens via resource competition or the production of antimicrobial compounds. This study aimed to conduct in vitro and in vivo screening of eight Pseudomonas strains against Ralstonia solanacearum (the causative agent of bacterial wilt) and to investigate underlying mechanisms of potential pathogen suppression. We found that inhibitory effects were Pseudomonas strain‐specific, with strain CHA0 showing the highest pathogen suppression. Genomic screening identified 2,4‐diacetylphloroglucinol, pyoluteorin, and orfamides A and B secondary metabolite clusters in the genomes of the most inhibitory strains, which were investigated further. Although all these compounds suppressed R. solanacearum growth, only orfamide A was produced in the growth media based on mass spectrometry. Moreover, orfamide variants extracted from Pseudomonas cultures showed high pathogen suppression. Using the “Micro‐Tom” tomato cultivar, it was found that CHA0 could reduce bacterial wilt disease incidence with one of the two tested pathogen strains. Together, these findings suggest that a better understanding of Pseudomonas–Ralstonia interactions in the rhizosphere is required to successfully translate in vitro findings into agricultural applications.
