Applying an Improved Dung Beetle Optimizer Algorithm to Network Traffic Identification

Network traffic identification is critical for maintaining network security and further meeting various demands of network applications.However,network traffic data typically possesses high dimensionality and complexity,leading to practical problems in traffic identification data analytics.Since the original Dung Beetle Optimizer(DBO)algorithm,Grey Wolf Optimization(GWO)algorithm,Whale Optimization Algorithm(WOA),and Particle Swarm Optimization(PSO)algorithm have the shortcomings of slow convergence and easily fall into the local optimal solution,an Improved Dung Beetle Optimizer(IDBO)algorithm is proposed for network traffic identification.Firstly,the Sobol sequence is utilized to initialize the dung beetle population,laying the foundation for finding the global optimal solution.Next,an integration of levy flight and golden sine strategy is suggested to give dung beetles a greater probability of exploring unvisited areas,escaping from the local optimal solution,and converging more effectively towards a global optimal solution.Finally,an adaptive weight factor is utilized to enhance the search capabilities of the original DBO algorithm and accelerate convergence.With the improvements above,the proposed IDBO algorithm is then applied to traffic identification data analytics and feature selection,as so to find the optimal subset for K-Nearest Neighbor(KNN)classification.The simulation experiments use the CICIDS2017 dataset to verify the effectiveness of the proposed IDBO algorithm and compare it with the original DBO,GWO,WOA,and PSO algorithms.The experimental results show that,compared with other algorithms,the accuracy and recall are improved by 1.53%and 0.88%in binary classification,and the Distributed Denial of Service(DDoS)class identification is the most effective in multi-classification,with an improvement of 5.80%and 0.33%for accuracy and recall,respectively.Therefore,the proposed IDBO algorithm is effective in increasing the efficiency of traffic identification and solving the problem of the original DBO algorithm that converges slowly and falls into the local optimal solution when dealing with high-dimensional data analytics and feature selection for network traffic identification.

Restudies on Body Surface of Dung Beetle and Application of Its Bionics Flexible Technique

A scanning electron microscope was used to observe the structures of the setae on the surface of a dung beetle Copris ochus, Motschulsky. There are lots of setae on the body surface, especially on the ventral part surface and lateral to the legs which are different in size, arrangement and shape. These setae have different lengths and many thorns on the whole seta. The top ends of these setae stand up without furcations which direct uprightly towards the surface of the touched soil. By the method of removing these setae, getting the insect weight before and after digging into the dung we affirm farther that the setae on the beetle body surface form the anti-stick and non-adherent gentle interface. The soil machines and components made by imitating the gentle body surface of beetles have favorable non-adherent results.

Factors impacting nanoindentation testing results of the cuticle of dung beetle Copris ochus Motschulsky

The cuticle of dung beetle is a layered composite material in micro- or nano-scale. Dung beetle can fly, walk and dig. It can shovel and compact dung of mammals into balls. It use foreleg to walk, midleg and hindleg to hold and impel dung ball. Its two foreleges as digging legs are developed. The factors impacting the nanoindentation testing results of the femur cuticle of forelegs of dung beetle Copris ochus Motschulsky were examined. The nanomechanical test instrument used for the tests was Hysitron nanomechanical system. The results shown that the holding time and loading time are important factors im- pacting the accuracy of such indentation properties as reduced modulus (Er) and the harness ( H ) of the femur cuticle of the forelegs of dung beetle Copris ochus Motschulsky in nanoscale. There exists a threshold holding time of 20 s for the reduced modulus of the femur cuticle. The tests of nanoindentation creep property and the regression analysis of relationship between the depth increment at the maximum load and the time further confirmed the correction of the above threshold holding time. There exist visco-elastic-plastic behaviour and creep phenomenon in the femur cuticle during indenting. Its creep property during the holding procedure at maximum load can be regressed by a general logarithmic equation. The equation fitted by the testing data is ? h = 54.83452 ln(0.00723t +1.00486), where, ? h is the depth increment at the maximum load and t is the time.

Microbial safety control of compost material with cow dung by heat treatment

Various kinds of pathogenic bacteria derived from the intestinal tract of animals exist in compost material like cow dung. In order to sterilize the pathogenic bacteria completely in compost material, the cow dung was put into a heat treatment machine in pilot plan, and harmless condition in short time was examined. The results indicated, pathogenic indicator bacteria such as coliform bacteria, fecal coliform, Escherichia coli and salmonella were all 106 cfu/g dw at the beginning, died rapidly when cow dung temperature rose to above 50~C, and not detected at 54-68~C for 6-24 h heat treatment. Coliform bacteria and salmonella in heated cow dung were not detected by re-growth culture and enrichment culture examination. Moreover, it was hardly influenced on the fermentation ability of composting microbe, organic decomposition bacteria. During heat treatment, the mesophile decreased rapidly and the thermophile stabilized or increased, and the most of composting microbe were bacillus in cow dung by fluorescence microscope, this indicated that bacillus was dominator and composting microbe in composting process.

Levels of Germinable Seed in Topsoil and Yak Dung on an Alpine Meadow on the North-East Qinghai-Tibetan Plateau

In order to clarify the interactive mechanism between grazing yak and alpine meadow on the Qinghai-Tibetan Plateau,our study assessed seed density（by species） in the topsoil of alpine meadow with different grazing intensities in the Tianzhu area,north-eastern margins of the Qinghai-Tibetan Plateau and their rates of occurrence in yak dung.Seed density in the topsoil of the lightly grazed,moderately grazed,heavily grazed and extremely grazed alpine meadows in November,2010 were 1 551,1 692,2 660 and 1 830 grains m-2,while in the same meadows in April,2011 densities were 1 530,2 404,2 530 and 2 692 grains m-2,respectively.In the cold season pasture,mean seed density in yak dung from November to April in the lightly grazed,moderately grazed,heavily grazed and extremely grazed sites were 121,127,187,and 120 grains kg-1of dry yak dung.The proportion of total seed numbers in yak dung to soil seed bank in lightly grazed,moderately grazed,heavily grazed and extremely grazed alpine meadow was 1.40,2.62,0.69,and 0.90%.12 species out of the 47 were not found in topsoil but were found in yak dung,10 species out of 45 were not found in yak dung but were found in the topsoil.Endozoochorous dispersal by yaks is therefore very important for soil seed bank and plant biodiversity and population dynamics in alpine meadows.

The Induction of Root Formation by Urea,IBA and Sheep Dung in Young Apple Tree

The effect of plant growth substance and fertilizer on root formation was studied in a newly planted apple tree (Malm pumila Mill / Malus hupenensis Rhed). The results indicated that urea and IBA ( indole butyric acid) and sheep dung all increased the total number and activity of new roots and changed the ratio of absorbing root to extensive roots obviously. Urea increased the number of extensive root and decreased the ratio of the root to shoot mostly. IBA lengthened the extensive root and increased the ratio of root to shoot obviously. Sheep dung increased the nu mber of absorbing root and increased the ratio of absorbing root to extensive root, divided new root into many branches, increased the fresh weight of the root and thickened the extensive root. The fresh weight of root increased and the ratio of root to shoot declined after urea was added to sheep dung. Both the ratio of absorbing root to extensive root and root fresh weight was increased after IBA was added to sheep dung, then the ratio of root to shoot had no change obviously.

Evaluation on Feed Factors Affecting the Dung Pollutants of Livestock and Poultry

The 30 pairs of feed and dung samples from the livestock and poultry farms with different scales were checked and analyzed. The results showed： a great linear relation existed between the feed factors and 7 pollutants such as ammonia nitrogen, phosphorus, copper, iron, arsenic, mercury, cadmium in livestock and poultry＇s dung. The main affecting factors of feed were respectively nitrogen, phosphorus, copper, and arsenic, which were totally feed ingredient elements. And it indicated that the dung pollutants such as nitrogen, phosphorus, copper, iron, arsenic, mercury, and cadmium could be regulated by controlling the feed ingredients. But the dung nitrogen did not have a linear relation with the feed factors. Reducing the nitrogen in feed did not mean the relative decrease of the dung nitrogen content. Feed consumption rate of unit weight did not have notable performances, and it did not show curve model after curve fitting method. The pollutant index of ammonia nitrogen, phosphorus, copper, and arsenic of the group whose feed consumption rate of unit weight was less than 20 g/kg·d was extremely remarkably lower than those of the 20 -30 g/kg·d group. The pollutant index of mercury, chromium, and cadmium showed the opposite performance. With the increase of feed consumption rate, each pollutant did not act in an increasing trend, of which the pollutant index of ammonia nitrogen and the general phosphorus presented a quadratic model trend. The feed consumption level of unit weight had an extremely remarkable effect on the pollution level rate and the eady warning level rate, showing the thrice model trend, of which the 20 -30 g/kg. d group was the maximal, respectively for 16.67% and 50%, which was the same with the above-mentioned law.

Assessment on Potential of Cow Dung Manure in <i>Zea mays</i>Production at Kiwere Village in Iringa Rural District, Tanzania

An assessment on potentiality of Cow dung manure in Zea mays production at Kiwere village in Iringa Rural District (7°37'17.3"S, 35°37'48.1"E) was conducted from December 2019 to June 2020. The idea of this assessment was influenced by soil fertility depletion and the fall of Maize production in Iringa region from 1990’s. A total of 10 farms, 5 farms for Cow dung manured and 5 for non-manured in which Maize growth was monitored for 6 months. Various parameters as height, width and weight of both Maize plants and Maize fruits were recorded. Soil qualities both chemical and physical characteristics were analysed and recorded but also weather (Temperature, humidity) together with soil pH were recorded throughout the assessment period. The p-value of <0.0001 (1.03702E-07) and <0.0001 (2.45684E-05) for height and width and the highest mineral chemical values in the Cow manured 10 plots indicated that Cow manure not only increase Maize production significantly but also supports the production of soil microbial and hence renewals the soil minerals and soil fertility as well. This is why the soil physical values in the Cow dung manured plots Organic matter, porosity, soil aeration and others were found to be higher and the soil comprised of Sandy Clay Loam. Farmers are strongly advised to use this multipurpose and potential manure in their unfertile soil. Cow manures are easily available in their environment and cheaper. -

Changes in Bacterial Density, CO₂Evolution and Enzyme Activities in Poultry Dung Amended Soil

The utilization of cattle and poultry manure as organic fertilizer improves soil productivity, but arsenic contaminated poultry dung may interfere in soil metabolism and soil fertility. The study was conducted to assess the effects of poultry dung as well as arsenic contamination on soil properties in 1%, 3% and 5% poultry dung amended soil and 1, 5 and 10 ppm sodium arsenite contaminated soil. pH and conductivity were found to be increasing with increase in poultry dung in soil. Other chemical parameters like nitrate, phosphate and organic carbon were found higher in poultry dung amended soil than that of arsenic contaminated soil. Soil bacteria, CO2 evolution and enzymatic activities like amylase, invertase and dehydrogenase were also found higher in poultry dung amended soil suggesting the effectiveness of poultry dung in enhancing soil productivity, even if it was contaminated by As through feed additive.

Amelioration of Saline Soil by the Application of Gypsum, Calcium Chloride, Rice Husk and Cow Dung

A pot experiment was conducted to investigate the effect of cow dung, rice husks, calcium chloride and gypsum on soil reclamation and compare the effect of organic and inorganic amendments on soil reclamation during the period of 5th March to 20th April, 2017. The experiment was laid to fit a completely randomized design (CRD) with seven treatments [Reference soil (T0), Cow dung (T1), Rice husk (T2), Gypsum (T3), Calcium chloride (T4), Cow dung + Rice husk (T5) and Gypsum + Calcium chloride (T6)] each having three replications for this experiment. After incubation (45 days), the laboratory investigation was carried out in the Soil, Water and Environment Discipline, Khulna University, Khulna, Bangladesh. Results indicate that the individual or combined effect of gypsum (T3) was more effective in changing EC and SAR. Gypsum application in combination with calcium chloride (T6) improved the soil chemical properties by reducing the EC. Among the treatment, calcium chloride (T4) had a remarkable effect in reducing sodium adsorption ratio and gypsum had a remarkable effect in reducing pH. Cow dung (T1), rice husk (T2), combination of cow dung and rice husk (T5) were less effective to reduce EC, pH and SAR. It’s measured for soils of different soil amendments varied significantly

Characterization of Digestates from Anaerobic Co-Digestion of Manioc Effluent, Human Urine and Cow Dung

This study focused on the characterization of digestates resulting from anaerobic digestion of manioc effluents from attiéké factories. Two types of digestate were characterized, one consisting of manioc effluent + urine and another composed of manioc effluent + urine + cow dung. As a result, these residues of bio-digestion rich in nutrients (NPK) can be used as agricultural fertilizer. Moreover, the determination of some microorganisms and heavy metals digestates allowed to better appreciate its fertilizing quality. These parameters remained in accordance with the quality standards of a digestate prescribed. These results show that digestates from anaerobic co-digestion of manioc effluents, urine and cow dung can be used without fear as an agricultural biofertilizer.

Organic Amendments with Poultry Manure and Cow Dung Influence the Yield and Status of Nutrient Uptake in Wheat (Triticum aestivum)

The field experiment cultivating wheat during the winter season from November 2014 to March 2015 was conducted in the “North Eastern Barind Tract Soils” at Kushadaha, Nawabganj, Dinajpur in Bangladesh. The wheat variety BARI Gom 26 was selected in focusing to evaluate the effects of organic amendments using poultry manure (PM) and cow dung (CD) on the growth, yield and nutrient uptake by the plant. The texture of the field soil was clay with acidic nature (pH 5.61). The trials comprise three treatments following a randomized complete block design (RCBD) replicated thrice. Results showed that significantly greater plant height, number of tillers per hill and straw yield were 98.10 cm, 3.66 and 5425 kg/ha respectively in receiving the treatment T2 than T3 (95.66 cm, 3.38 and 4483 kg/ha) and T1 (control). Spike length, 1000 grain weight and grain yield were 9.23 cm, 39.81 kg/ha and 3100 kg/ha respectively also higher in T2 treatment than T3 (8.76 cm, 38.51 kg/ha, 3091 kg/ha) with no statistical differences among them. Therefore, the treatment T2 (PM) comprised of poultry manure and NPK exhibited as the best treatment for producing the highest in all growth and yield parameters of wheat. In wheat grain, the content of N, P, K, S, Mg, Zn and B ranged from 1.080% to 1.380% N, 0.390% to 0.398% P, 0.780% to 0.840% K, 0.079% to 0.111% S, 0.181% to 0.187% Mg, 25.56 to 29.77 ppm Zn and 10.12 to 12.54 ppm B. Similarly in straw, nutrients content ranged from 0.220 to 0.300% N, 0.045% to 0.074% P, 0.970% to 1.250% K, 0.152% to 0.191% S, 0.097% to 0.101% Mg, 10.78 to 13.23 ppm Zn and 27.98 to 2989 ppm B. Therefore, organic amendment with 5-ton cow dung (CD) ha-1 with a recommended dose of NPK significantly increased the content of N, S, Mg, Zn and B in the grain and straw of wheat. Alternatively, the poultry manure treatment with NPK significantly increased the content of P and K in the grain and straw of wheat. However, results revealed that the treatments T2 and T3 comprising a recommended dose of NPK with poultry manure and cow dung respectively could increase the content of N, P, K, S, Mg, Zn and B in wheat. The overall results expressed that the poultry manure treatment with NPK (T2) exposed as superior for producing the top growth and yield attributes of wheat in the studied area.

Performance analysis of cow dung as an eco-friendly additive material for sustainable moulding and casting

In the present work,an attempt is made to partially replace high cost silica sand with sustainable eco-friendly cow-dung.The practical utility of cow dung as an additive material that facilitates binding in sand moulds has been tested.The Taguchi method is used to plan and conduct nine experiments with three replicates each.Pareto analysis of variance study is performed to understand the practical significance of moulding sand variables,that is,percentage of cow dung,clay,water,and degree of ramming on sand mould properties.The conflicting multiple objective functions(maximize mould hardness,and minimize collapsibility and gas evolution)are optimized by utilizing the Data Envelopment Analysis Ranking(DEAR)method.The optimal parameters i.e.6%of clay,4%of water,5%of cow-dung and 4 numbers of ramming strokes are obtained by applying a hybrid Taguchi-DEAR method.These parameters show the best moulding properties are:mould hardness 55,gas evolution 5.9 ml·g-1,and collapsibility 470 g·cm-2.Thereafter,a Lovejoy coupling made of aluminium is cast in the sand mould prepared with cow dung and without cow dung,with the optimum set of parameters.The mechanical properties,surface finish,and microstructure of the casting cast with cow-dung are better than that without cowdung.

Screening and Identification of Efficient Cellulose-degrading Strain and Its Preliminary Application in Sheep Dung Compost

The paper was to solve the problems of incomplete fermentation and more cellulose impurities in finished products caused by high cellulose content in sheep dung and accessory substances in composting production.[Method]Efficient cellulose-degrading strains were screened from different animal dung samples and three widely used commercial microbial composting strains(RW,BDM and JBB).The target strains were comprehensively screened by Congo red staining,degradation test of filter strips and cellulase activity test,and the strains screened were identified by physiological and biochemical tests and molecular tests.The strain was used to produce bioaugmentation strain,which was compared with composting fermentation of commercial strains.The temperature of composting process and the physical and chemical properties of finished products were tested to determine whether it met the national standards.[Result]A strain(M2)with strong cellulose-degrading ability from horse dung was screened,and its cellulase activity was(126.06±0.36)U/mL,higher than that of cellulose strain with the highest enzyme activity in commercial strains.Through morphological,physiological and biochemical identification and 16S rDNA sequence analysis,strain M2 was identified as Sphingomonas paucimobilis belonging to Sphingomonas sp.Compared with commercial strains,the bioaugmentation strain effectively improved the cellulose-degrading ability of strains after composting fermentation.The products were uniform in color,without obvious cellulose impurities,and the total nutrients were improved to a certain extent.[Conclusion]The strain M2 screened can be used for the development of specific strain for sheep dung composting.

Development of a Batch-Type Biogas Digester Using a Combination of Cow Dung, Swine Dung and Poultry Dropping

The overdependence on crude oil in African countries warrants the need for alternative sources of energy. A 56-litre-capacity biogas digester was designed, fabricated and evaluated. Investigations were made into the production of biogas from the mixture of cow dung, swine dung and poultry dropping. Standard equations and models were used in the design of the components of the manually operated digester. The digester temperature, ambient temperature and pH were monitored during the experiment. The proximate analysis showed that volatile solid, total solid and moisture content for the mixed substrates at the initial stage were: 64.7%, 83.5% and 13.5% respectively. Similarly, at the digestion stage, the volatile solid, total solid and moisture content were: 54.1%, 22.6% and 74.4% respectively. Advancement of decomposition leads to gradual increasing pH value from 7.2 to 7.4, which indicates the stability of organic matter. The moisture content on a wet basis was initially 13.5%. This value latter increased to 74.4%. On the average, 15 kg of mixed substrates with 25 litres of impure water produced biogas within 25 days of digestion. The gas produced from mixed substrates became flammable with blue flame after 16 days of production, indicating that the ratio of methane gas generated with the three mixtures of fresh animal waste was higher than other gases produced.

Experimental Study of Biogas Production from Cow Dung as an Alternative for Fossil Fuels

To treat the problem of fossil fuel usage and greenhouse gas emissions, biogas is considered a potential source of clean renewable energy. The aim of the work is to analyze the amount of biogas and ph from cow dung when an anaerobic digester operates in the mesophilic mode. In this study is presented the experimental investigation of biogas production from cow dung as an alternative energy resource. This is work using an 18 Liters capacity plastic as prototype biogas plant, plant to inspect the anaerobic digestion in producing biogas. The digester was batch operated and daily gas produced from the plant was observed for 30 days. The digester was fed within the ratio of 1:1 of dung to water respectively. The operating temperatures of the digester were maintained within mesophilic conditions. The Biogas production from cow dung fluctuates from the first day to the thirtieth day between 0 and 340 ml. The pH of cow dung is gradual reduction within the retention period.

Influence of Climate Temperature on the Valorization of Dung-Wastewater Slaughterhouse Biogas in Two Regions: In Chad and Senegal

In this work, we have produced biogas by co-digestion of cow dung and slaughterhouse wastewater under different climate temperatures in two countries: N’Djamena in Chad, a country of Central Africa and Dakar in Senegal, a country of West Africa. In a first approach, we put the cow dung in cans of 1.5 L, hermetically closed. The goal was to know how long you could produce biogas. Then we built a bio-digester to produce biogas for cooking. Each bio-digester was exposed to receive solar heat that varied between 27°C to 41°C in Chad and between 24°C to 30°C in Senegal. Influenced by the high temperature and a minimum residence time, the experiments showed that the N’Djamena test produced biogas more quickly than the Dakar test which, on the contrary, had a low temperature and a long residence time. The production of biogas began at the end of seven days with flammability on the twenty-first day for the bio-digester in Chad and after twenty-seven days with a flammability on the thirty-sixth day for the bio-digester of Senegal. The different digestates were valorised in fertilizers, bricks and green coal. Our research aims to meet the living conditions of the rural world specifically for women by reducing their work and thus allowing them to have more time to self-educate and educate their children.

Production of Biogas from Co-Digestion of Cow Dung, Saw Dust and Maize Husk

The co-digestion of cow dung, with maize husk for biogas production at laboratory scale was investigated. The study was carried out at a temperature range of??24°C - 30°C and pH range of 5.5 - 6.5 for a period of 60 days with a total solid concentration of 7.4% in the digester sample (fermentation slurry). Water displacement method was used to collect the biogas produced which was subsequently measured. 444.8 mL was the cumulative biogas yield at the end of 60 days retention time in the digester 1, which comprised of cow dung, maize husk, and water. Digester 2, which is made up of sawdust, cow dung, and water produced negligible biogas at the end of 60 days of the experiment. X-RF analysis revealed high presence of elements like silica, aluminium oxides, and aluminium oxides in cow dung, maize husk, and sawdust respectively. The preponderance of alkanes and methyl group inmaize husk makes it to produce biogas compared to saw dust as shown by the Fourier transform infrared spectroscopy (FTIR) that was carried out to identify the various functional groups. The potential of maize husk to produced biogas was also established. The kinetic modeling shows that there was an increase in biogas yield as the retention time increases as depicted by the linear model.

Comparative Effect of Foliar Application of Cow Dung, Wood Ash and Benlate on the Disease Initiation and Development of Roselle (Hibiscus sabdariffa L.) Leaf Spot Disease Caused by Coniella musaiensis Var. Hibisci. in Makurdi, Central Nigeria

A study on the comparative effect of cow dung, wood ash and benlate for the control of leaf spot disease of Roselle (Hibiscus sabdariffa L.) was carried out following the preparation and foliar application of the materials on selected Roselle plants of the green and red accessions (Acc1 & Acc3) in the field. The cow dung was fermented for 14 days while sour milk was added to wood ash, dissolved and all filtered and labeled. The spraying commenced soon after the plants were thinned to one and was done weekly until after 50% of the plants had flowered. Results showed significant (p = 0.05) difference between benlate, the synthetic fungicide and the bio-fertilizers (cow dung and wood ash) for the two years of the study. Disease severity was significantly lower in the benlate than in the bio-fertilizers. There was no significant difference in yield between the treatments although higher yield was recorded in benlate. Though the bio-fertilizers could not suppress infection, they aided the growth of the plants by boosting luxuriant growth. The result showed that these bio-fertilizers cannot be used as substitute to the synthetic fungicide for the control of this leaf spot disease caused by Coniella musaiensis var. hibisci. However, since they give equally good yield the bio-fertilizers can still be used to minimize the reliance upon use of chemical fungicides.

Inhibitory Activities of Sole Cow Urine and Combined Cow Dung/Cow Urine against the Blight Disease of Ribwort (<i>Plantago lanceolata</i>) at the Cistercian Monastery in Mbengwi, Cameroon

Ribwort (Plantago lanceolata) is a small glabrous to pubescent perennial plant that is native to Europe, America, North Africa and Asia. Nowadays, it is cultivated in many countries across the globe, including Cameroon due to its extensive use in livestock and medicine. Unfortunately in Cameroon, however, the plant has been highly infested by blight, reducing its yield and medicinal value. To reduce blight infestation of ribwort and improve plant yields, we aimed to compare the efficacy of sole cow urine and combine cow dung/cow urine to inhibit blight disease caused by Phyllosticta ophiopogonis on ribwort. At the Cistercian Monastery in Mbengwi, Momo Division, Cameroon, we used a Randomized Complete Block Design (RCBD) with 3 Blocks consisting of two treatments (cow dung mixed with cow urine (combine cow dung/urine) and sole cow urine) and one control. After spraying the different blocks of ribworts plants with combined cow dung/urine and sole cow urine at a dosage of 3% concentration, we found an incidence of blight disease of 32.8% and 35.0% on ribworts sprayed with combined cow dung/urine and sole cow urine, respectively, compared to 67.8% in the control. This implies that a mixture of cow dung/cow urine reduces the incidence of blight disease significantly. Furthermore, our pathogenicity test showed that Phyllosticta ophiopogonis (fungus) was responsible for the blight disease. Therefore, to increase ribwort growth, improve adaption and reduce Phyllosticta ophiopogonis fungal infestation in Cameroon, we recommend that the plant should be sprayed with a mixture of cow dung and cow urine at 3% concentration.
