Susceptibility of Sweet Potato Varieties to Meloidogyne incognita and Use of Effective Microorganisms and Compost Manure for the Disease Management Aishat Adetola Anifowose, Nkechi Betsy Izuogu, Benoit Katchitche Sossou Pakistan Journal of Nematology, 2023 To address the constraints posed by root-knot nematodes (RKN) and hazards of chemical nematicides in sweet potato production, effective microorganisms (EM) and compost manure were applied singly and in combination on two varieties of sweet potato under field and -screenhouse conditions. The trials were 2x5 (screenhouse) and 2x4 (field) factorial experiments fitted into a randomized complete block design (RCBD), respectively, and the field was naturally infested. Each pot in the screenhouse was inoculated with 2400 M. incognita juveniles at planting. Compost manure was incorporated a week before planting at 1.5 t/ ha for the single treatments and at 0.75 t/ha at planting for the combined treatments. EM was applied twice at a two-weeks interval at 4000 l/ha and 2000 l/ha for the single and combined treatments, respectively. The nematode-inoculated, untreated pots and plots served as negative controls. Generally, the increase in growth and yield parameters and decrease in nematode population was significantly higher (P=0.05) in treated plants than in control plants. Galling was most severe in negative control plants with poor yield. Even so, the yellow jersey variety was more susceptible to Meloidogyne incognita infection. However, the combination of EM and compost manure had significantly higher performance than the other treatments, especially on the Boniato variety. The implications of EM combined with compost manure as eco-friendly control of RKN infection in sweet potatoes in a changing climate are noteworthy and should further be tested and favourably considered for use by the potatoes farmers for adoption.
Controlling root-knot nematode Meloidogyne incognita in tomatoes using modified effective microorganisms-fermented plant extract and compost manure Benoit Katchitche Sossou, N.B. Izuogu, Aishat Adetola Anifowose, H.E. Ahamefule International Journal of Recycling of Organic Waste in Agriculture, 2022 Purpose Nematode diseases are major constraints in tomato production. Screenhouse and field experiments were conducted to assess the efficacy of Effective Microorganisms-Fermented Plant Extract (EM-FPE) and compost manure singly and in combination on Meloidogyne incognita infecting tomatoes.Method Screenhouse and field experiments were designed respectively as 2×5 and 2×4 factorial fitted into a completely randomized design (CRD) in the screenhouse and randomized complete block design (RCBD) on the field. For single treatments, 100 ml of EM-FPE or 200 g of compost was used per plant while 50 ml of EM-FPE and 100 g of compost were combined and used per plant for treatment combination. Pots that did not receive any treatment served as control. Data were collected on growth parameters, fruit production, galling, and soil nematode population. The data collected was subjected to analysis of variance (ANOVA) where significant differences in means were separated using Fisher’s Least Significance Difference (LSD) Test at P = 0.05.Results In both trials, treated plants performed significantly better. No significant difference was recorded among the three treatments for soil nematode population and root galling on the field. But in the screenhouse trial, plants treated with the combination of EM-FPE and compost recorded higher soil nematode population (150) and root galling (7) at harvest but the plants performed well. Among the treatments, compost manure applied singly gave the best result with respect to vegetative growth, flower formation, and yield of the tomatoes.Conclusion This study reveals that both treatments, EM-FPE, and compost manure could be relied on for effective control of Meloidogyne incognita in tomatoes.
Genetic Structure of Cucumber Mosaic Virus From Natural Hosts in Nigeria Reveals High Diversity and Occurrence of Putative Novel Recombinant Strains Oluropo A. Apalowo, Adedapo O. Adediji, Olusegun S. Balogun, Temitope I. Fakolujo, Joy M. Archibong, Nkechi B. Izuogu, Mohamed A. Abdelgawad, Mohammed M. Ghoneim, Suleiman Mustapha, Fadi S. I. Qashqari, Gaber E. Batiha, Gabriel I. Atiri Frontiers in Microbiology, 2022 Cucumber mosaic virus (CMV, Bromoviridae: Cucummovirus), one of the most widespread plant viruses with several hosts, causes huge losses in yield quality and quantity. The occurrence of various CMV strains and high genetic diversity within the virus complicate its management. We describe the population structure of CMV in Nigeria using partial RNA1 and RNA3 gene sequences from three natural hosts: pepper (Capsicum annuum), tomato (Solanum lycopersicum), and watermelon (Citrullus lanatus). One hundred and six leaf samples were obtained from 16 locations across Nigeria, and specific primers were used to amplify the two gene fragments using PCR. Twenty-four samples tested positive for CMV using RNA1 primers, and amplicons were sequenced from 12 isolates, revealing 82.94–99.80% nucleotide and 85.42–100% amino acid sequence similarities within the population. The partial RNA3 fragment, corresponding to the complete coat protein (CP) gene, was sequenced from seven isolates, with 95.79–97.90% and 98.62–100% nucleotide and amino acid intrapopulation similarities, respectively. The isolates belonged to subgroup IB and formed distinct phylogenetic clusters in both gene sets, indicating putative novel strains. Recombination signals, supported by phylogenetic inferences, were detected within the RNA1 dataset (P ≤ 0.05) and identified a recombinant isolate within the Nigerian sequences. No recombination was detected within the CP genes. Population genetics parameters established high diversity within the Nigerian population compared to other isolates worldwide, while selection pressure estimates revealed the existence of negative selection in both gene sets. Although CMV subgroup IB strains were postulated to originate from Asia, this study reveals their prevalence across several hosts from different locations in Nigeria. To our knowledge, this is the first comprehensive description of a recombinant CMV subgroup IB isolate from West Africa, which has implications for its robust detection and overall management.
A review on Borreria verticillata: A potential bionematicide, channeling its significant antimicrobial activity against root-knot nematodes Nkechi B. Izuogu, Oluwatoyin E. Bello, Oluwasesan M. Bello Heliyon, 2020 Phytopesticides are human-friendly beside been easily accessible and bio-degradable, are therefore environmentally friendly compared to the synthetic pesticides which huge adverse effects on human, animals and the ecosystem. Plants are large reservoir of secondary metabolites largely untapped or under-tapped for use as pesticides. One problem associated with this is to identify plants which can be assessed and further exploited for this use. Borreria verticillata belongs to Rubiaceae, it is native to South Americas but gained popularity globally. It is known as a weed, showing resistance to many synthetic pesticides and can be grown on a wide range of soil types. B. verticillata is used traditionally against skin diseases such as eczema, infectious dermatitis and scabies. Its antimicrobial application is large and efficient as revealed by most authors. This article inclines to propose and offer current studies with information on the various application of this plant species against various microorganisms, thereby extending its use against plant parasitic nematodes which cause severe yield losses to numerous agricultural crops. Most search engines, journals and dissertation search engines i.e. Google scholar, pubmed, sciencedirect, scopus, web of science, springer, elsevier, like Open-thesis, OATD, ProQuest and EthOs were queried by employing titles such as B. verticillata, Borreria verticillata and biological activity of B. verticillata. The most synonymous name was queried too i.e. Spermacoce verticillata. This review suggests a main point about this resistant weed i.e. its significant antimicrobial activity. It further emphases the need exploits this useful effect against nematodes since they are microorganisms. Phytochemistry of the B. verticillata was gathered in this study and the compounds isolated from the plant i.e. terpenes, iridoids, flavonoids and alkaloids (29 compounds) further provide a basis for a significant antihelmintic effect. The review concludes on the need to extends its antimicrobial activity to sustainable agriculture. Since it is a very common plant in Nigeria, it is easily accessible to farmer protect their cultivations from plant-parasitic nematode attacks.
Response of tomato (Solanum lycopersicum) cultivars to root-knot nematode (meloidogyne incognita) infection under organic manure application Research on Crops, 2020 The need to produce crop in an eco-friendly manner using organic agriculture that avoids using synthetic chemicals and fertilizers become imperative as a way of protecting man, other beneficial organisms from chemical toxicity and environmental pollution. This experiment was, therefore, conducted in screen house during two consecutive years of 2017 and 2018 at Teaching and Research Farm, Landmark University Omuaran, Kwara State, Nigeria to investigate the differential response of five tomato cultivars infested with root knot nematode under both organic and inorganic fertilizers application in order to determine the most resistant cultivars with the view of recommending such cultivar(s) to farmers, who may wish to go into large scale production of the crop in Southern Guinea Savannah ecological zone, Nigeria. Poultry manure was used as soil amendment and incorporated into the soil at the rate of 1.42 t/ha, while NPK was applied at the rate 266 kg/ha. The experimental design was 5 × 2 × 2 factorial experiment, made up of five tomato cultivars, (Tropimech, Rio Grande, Dan hausa, Igede local and Omuaran local) with two manure types (Poultry and NPK fertilizer) and two media application (inoculated and uninoculated). Data were taken on Plant height, number of leaves, stem girth at 6, 8, 10 and 12 weeks after planting, number of flowers and number of days to 100% flowering, number of fruit, fruit weight (yield component), soil nematode population and root gall index. The results of the experiment showed that poultry manure recorded the highest vegetative growth (119.07 g/plant) and tomato yield (133.42 g/plant) even under high level of nematode infestation. The cultivar Igede local showed the highest level of nematode infection tolerance despite the high level of M. incognita infestation. It is the highest yielding among the tested cultivars under organic amendment condition and the most tolerant to nematode infection. Igede local is, therefore, recommended for use as seed in all nematode endemic soil.
Control of Root-Knot Nematode (Meloidogyne incognita) in Tomato (Solanum lycopersicum) Crop Using Siam Weed (Chromolaena odorata) Compost Manure Stephen A. Abolusoro, Aruna Olasekan Adekiya, Charity Aremu, Sunday Ige, Nkechi B. Izuogu, Patricial F. Abolusoro, Avwerosuo Erere, Samuel Obaniyi Journal of Horticultural Research, 2020 A field experiment was conducted at Landmark University Omu-Aran, Nigeria from June to November 2017 and repeated at the same time in the year 2018 on a nematode infested soil to evaluate the effects of different amounts of Siam weed compost on the performance of root-knot nematode (RKN) infested tomato. The compost was applied a week before planting as soil amendment at the amount of 0.0, 0.5, 1.5, and 2.0 t·ha−1, while carbofuran was applied at the rate of 3.0 kg·ha−1. Four weeks old tomato seedlings cultivar ‘Roma VF’, which is susceptible to RKN, was transplanted to already prepared soil. Results of the experiment showed that the compost, especially in the amount 2 t·ha−1 and carbofuran at 3 kg·ha−1, brought about significant reduction of the population of RKN in soil and roots, and a significant increase in the growth and yield of tomato. The result of the experiment showed that Siam compost can be used for the managing root-knot nematodes in tomato cultivation, as an environmentally safe factor.
Effect of Root-knot Nematode (Meloidogyne incognita) on the Nodulation of Some Varieties of Cowpea (Vigna unguiculata L. Walp) N.B. Izuogu, T.U. Olajide, E.K. Eifediyi, C.M. Olajide Scientia Agriculturae Bohemica, 2019 Screenhouse and field trials were conducted at the University of Ilorin, Nigeria in 2013 and 2014 to investigate the effect of root knot nematode (Meloidogyne incognita) on the nodulation of five varieties of cowpea (IT89KD-288, IT82D-994, IT93K-452-1, T89K-391 and TT97 568-18). Half of the experimental plants were inoculated with Meloidogyne incognita eggs (n = 1500) while the remaining half served as uninoculated control plants. Data on growth and yield of cowpea, root gall, nodulation, and nematodes population densities in nodules were collected. Other parameters assessed included colour of dissected infected and uninfected nodules, texture of the nodules and varietal performance of the cowpeas. The results of both screenhouse and field trials were consistent in yield and visual observations of texture and colour. The yield of nematode-free varieties was significantly higher than that of M. incognita-infected ones. Infected nodules were dark brown in colour while the healthy ones were pink. For the field trials, nodulation counts in nematode inoculated plants were inversely proportional to the number of galls in their uninoculated counterparts in some varieties. Of all varieties, IT89KD-288 was most resistant to M. incognita. Due to high cost involved in the management of nematodes, especially with synthetic chemicals, variety IT89KD-288 is recommended for use in nematode endemic areas in Nigeria. Further study needs to be done on the histopathology of the infected and uninfected roots and nodules of these cowpea varieties.
