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 <em>Phyllosticta ophiopogonis </em>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 (<em>cow dung mixed with cow urine </em>(<em>combine cow dung/urine</em>) <em>and sole cow urine</em>) and <em>one control</em>. 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 <em>Phyllosticta ophiopogonis</em> (<em>fungus</em>) was responsible for the blight disease. Therefore, to increase ribwort growth, improve adaption and reduce <em>Phyllosticta ophiopogonis</em> fungal infestation in Cameroon, we recommend that the plant should be sprayed with a mixture of cow dung and cow urine at 3% concentration.展开更多
