First report of loose kernel smut of sorghum caused by Sporisorium cruentum in Egypt.

Abstract

In 2017, sorghum (Sorghum bicolor) cv. Dorado plants cultivated in several areas in Upper Egypt (Qena governorate), exhibited symptoms of loose kernel smut disease. In the field, plants affected by loose kernel smut were initially mostly stunted and had thin stems and panicles which emerged earlier than those of healthy plants. Later, all kernels of infected panicles were replaced by smut sori. The causal pathogen was isolated and identified as Sporisorium cruentum based on morphological and pathogenicity analyses. This is thought to be the first report of loose kernel smut on sorghum in Egypt.
