Animal manure rhizobacteria co-fertilization suppresses phytonematodes and enhances plant production: evidence from field and greenhouse

Plant growth promoting rhizobacteria (PGPR) and their role in plant-parasitic nematodes control: a fresh look at an old issue

“…Several PGPR strains are known to display a reduction in gall number of RKN species, including Bacillus firmus T11, B. cereus N10w, B. aryabhattai A08, Paenibacillus barcinonensis A10, and P. alvei T30 (Viljoen et al 2019). A greenhouse experiment conducted on cucumber with the strains Pseudomonas fluorescens and Serratia marcescens resulted in a significant decrease in gall index and egg mass of RKN species compared with the untreated control group, and these strains are now considered biocontrol agents compared with M. incognita (Ali et al 2021). Examples of PGPR shown in Table 2 are used as biological control agents for PPN suppression.…”

“…Corynebacterium paurometabolous has been found to generate chitinase and hydrogen sulfide, both of which impede hatching of nematode juveniles (Mena et al 2002). Pseudomonas fluorescens and S. marcescens were found to decrease nematode populations in roots of cucumber (Cucumis sativus) (Ali et al 2021). On testing a strain of Lysobacter capsici newly isolated from Korean soil (Lee et al 2015) for its biocontrol activity against root-knot nematodes in tomato (Solanum lycopersicum), this strain was found to express both chitinase and gelatinase activities.…”

Phyto-Friendly Soil Bacteria and Fungi Provide Beneficial Outcomes in the Host Plant by Differently Modulating Its Responses through (In)Direct Mechanisms

“…Tomato ( Solanum lycopersicum L.) is one of the most consumed vegetables and is widely recognized as a model species for basic and applied research on fruit quality and for studies on the genetics and molecular aspects of disease resistance mechanisms [ 139 , 140 ]. PGPMs exert their plant-growth-promoting abilities also on tomato plants through the above-described direct and indirect mechanisms improving nutrient uptake [ 141 , 142 ], (a)biotic stress tolerance [ 102 , 143 , 144 , 145 ], and fruit quality and yield [ 146 , 147 ].…”

Suppression of Meloiodogyne incognita (Tylenchida: Heteroderidae) and Tylenchulus semipenterans (Tylenchida: Tylenchulidae) using Tilapia fish powder and plant growth promoting rhizobacteria in vivo and in vitro

“…Indiscriminate usage of chemical nematicides bear the risk of harm to humans, animals, plants, and the ecosystem as a whole because of their a non-target impacts. Therefore, biological control of nematodes has drawn interest from researchers (Ali et al, 2022;Feng et al, 2022).…”

“…Plant growth-promoting rhizobacteria are alsoknown as plant health-promoting rhizobacteria or nodulepromoting rhizobacteria (Hayat et al, 2010) and can be divided into two groups depend on their habitat, viz., iPGPR (i.e., symbiotic bacteria), which live inside plant cells, produce nodules, and are restricted to particular structures, and ePGPR (i.e., free living rhizobacteria), which exist outside plant cells, do not produce nodules, but nevertheless promote plant development (Gray & Smith, 2005). The use of PGPR in conjunction with animal manures have been suggested as aneffective, environmentally friendly method to control a variety of nematode communities and improve cucumber (Cucumis sativus) and tomato (S. lycopersicum) development might be considered as an alternative to the synthetic nematicide oxamyl (Ali et al (2022).…”
