Then sterile disks (0.625 cm in diameter) were located at the distance of 0.5 cm from colonies of the rim. & C. Miyake) Shoemaker. The journal publishes papers that describe translational and applied research focusing on practical aspects of disease diagnosis, development, and management in agricultural and horticultural crops. each amino acid is added to the protein chain by. However, some Bipolaris species have short and straight conidia with intermediate conidial characteristics. Bipolaris species are found in soils and vegetation, and have been identified in brain, lung, and sinus infections. To assess the efficacy of the assay, DLA results were compared with those from both screenhouse and field experiments. Maize sheath blight and southern corn leaf blight are major global threats … Plant Disease is the leading international journal for rapid reporting of research on new, emerging, and established plant diseases. The fungal strains tested were the maize pathogens Fusarium graminearum, Curvularia lunata, and Bipolaris maydis, together with one human fungal pathogen Candida albicans. FUNGI: Kingdom Fungi A.
