“…Manulis et al [ 104 ] studied the production of IAA and the pathways of its synthesis by various Streptomyces spp., including Streptomyces violaceus , Streptomyces griseus , Streptomyces exfoliates , Streptomyces coelicolor , and Streptomyces lividans . Reddy et al [ 105 ] isolated Streptomyces atrovirens from groundnut roots. This bacteria has shown excellent growth-promoting activity not only on groundnut but also on a number of other crops.…”

“…Very few Streptomyces -based commercial formulations are available in the worldwide market, compared with products based on Streptomyces metabolites; the former are mainly indicated for pest and disease control. Additionally, few products have been specifically commercialized for plant growth promotion, although significant research has been carried out on actinomycete production of growth-promoting substances [ 212 ]. One reason for this gap may reside in the difficulty of preparing a commercial product formulation with one or more streptomycetes as an active substance.…”

There has been many recent studies on the use of microbial antagonists to control diseases incited by soilborne and airborne plant pathogenic bacteria and fungi, in an attempt to replace existing methods of chemical control and avoid extensive use of fungicides, which often lead to resistance in plant pathogens. In agriculture, plant growth-promoting and biocontrol microorganisms have emerged as safe alternatives to chemical pesticides. Streptomyces spp. and their metabolites may have great potential as excellent agents for controlling various fungal and bacterial phytopathogens. Streptomycetes belong to the rhizosoil microbial communities and are efficient colonizers of plant tissues, from roots to the aerial parts. They are active producers of antibiotics and volatile organic compounds, both in soil and in planta, and this feature is helpful for identifying active antagonists of plant pathogens and can be used in several cropping systems as biocontrol agents. Additionally, their ability to promote plant growth has been demonstrated in a number of crops, thus inspiring the wide application of streptomycetes as biofertilizers to increase plant productivity. The present review highlights Streptomyces spp.-mediated functional traits, such as enhancement of plant growth and biocontrol of phytopathogens.

“…For instance, in inoculating soil with a biocontrol agent, microbes are mixed with soil or sowing furrows or are spread in the field by dripping systems [230]. Seed inoculation methods commonly involve soaking seeds in a suspension containing the selected biocontrol agent(s); alternatively, they are mixed with suitable wetting agents [228][229][230][231][232]. The inoculation of vegetative parts is done by spraying a suspension of the biocontrol agent to aerial parts of the plant or dipping the roots of seedlings into a microbial suspension prior to transplantation [230,232].…”

“…In the last two decades, there has been an increasing interest in antibiosis by PGPB and such biocontrol mechanisms are now better understood [112]. Several metabolites with antibiotic nature produced by pseudomonads have been studied and characterized so far, e.g., the cyclic lipopeptide amphysin, 2,4diacetylphloroglucinol (DAPG), oomycin A, the aromatic polyketide pyoluteorin, pyrrolnitrin, the antibacterial compound tropolone [113,114]. Other bacterial genera, such as Bacillus, Streptomyces, Stenotrophomonas spp., produce the macrolide oligomycin A, kanosamine, the linear aminopolyol zwittermicin A, and xanthobactin [115,116].…”

“…Rhizobacteria is mostly effective in the growth of the plants but some bacterial strains like ISE14, CCR80, R13 and R33 proved antagonistic to fungal attack in chilli plants (Emmert, Handelsman, 1999). Plant growth-promoting rhizobacteria (PGPR) not only increased the production of pepper Reddy et al, 2016), but Bacillus vallismortis strain BS07 and B. subtilis CAS15 were found as a potential bio-control agent particularly against Phytophathora blight, Fusarium wilt and anthracnose disease of chilli plants. Plants treated with this rhizobacterium also showed significant boost in chlorophyll contents of leaves and increased fruit yield (Rajkumar et al, 2005).…”

Phytophthora capsici is the most destructive pathogen of vegetables that represents a serious threat to chilli pepper plants. We discussed the control of P. capsici through manipulation of genetic architecture of chilli plant and endophytic microorganisms. The function of various genes encoding transcriptional regulatory and defense related putative proteins such as pathogen-related protein (PR), anti-microbial peptides (AMPs), polygalacturonaseinhibiting proteins (PGIPs), lipid transfer protein (LTP), pectin methylesterase (PME), leucine-rich repeat proteins (LRRs), osmotin-like and thaumatin-like protein, in Capsicum was also analyzed. The bio-control of P. capsici by using various strains of Bacillus, Trichoderma, Pseudomonas, Chryseobacterium and Rhizobacteria was demonstrated. We also discussed the enhanced resistance to P. capsici infection by treatment with a variety of abiotic and biotic inducers that act on defence signalling pathways involved in disease resistance. We highlighted the vulnerability of chilli crop with reference to its genetic resources against Phytophthora blight. Disease control through chemicals is becoming problematic, so we proposed other ways to control the disease severity. This review highlights the economic significance of chilli pepper (Capsicum annuum L.) along with disease management strategies against P. capsici. This pathogen has posed a serious threat to chilli crop worldwide.
