Black point describes the discolored appearance of harvested grain infected by fungi during kernel development. Infection is favored by humid field conditions (>90% relative humidity) while kernel moisture content exceeds 20%. Severity can increase for infected grain stored under humid conditions. Severe infections often reduce seed germination levels. Kernels darkened by black point fungi are considered damaged by USDA-FGIS grain grading standards with only 2 and 4 percent damaged kernels permitted in US No. 1 and No. 2 grades, respectively. Black point is more prevalent under irrigated than dryland conditions.
