Caracterización morfológica, fisiológica y patogénica de moniliophthora roreri aislados de cinco provincias de la costa ecuatoriana

The moniliasis of cacao, caused by the fungus Moniliophthora roreri, is the main problem, so is necessary to deepen the knowledge of the agent and the differences between populations of the fungus from various sources. To achieve the objectives of this research was carried out on samples collected i...
