Leaf inoculations with M. Cryptogamic Botany, 2 Title Symptoms Caption Blight developing between ‘fisheye’ spots on Zea mays. Despite the increasing importance of TSC in maize and the resulting need to carry out epidemiological or control studies, there is no standardized quantification method of the disease that provides easily reproducible results among investigators or institutions; therefore, the objective of this investigation was to design and validate a diagrammatic logarithmic severity scale for the maize – Phyllachora maydis and Monographella maydis – pathosystem that allows the evaluation mandha the damage maia by the disease in fields, analyzing the accuracy, precision and reproducible values generated with its use.

The disease they cause occurs in the cooler and higher elevations of Mexico, and Central and South America, and the West Indies, so their ability to spread over land through other climatic zones may be limited. The pycnidia of the Linachora asexual state appear early in infection Parbery, ; Hock et al. High levels of accuracy were observed; r 2 was comprised between the range of 0.
