Loose Smut
Loose smut of barley is caused by Ustilago nuda. It is a disease that can destroy a large proportion of a barley crop. Loose smut replaces grain heads with smut, or masses of spores which infect the open flowers of healthy plants and grow into the seed, without showing any symptoms. Seeds appear healthy and only when they reach maturity the following season is it clear that they were infected. Systemic fungicides are the major control method for loose smut.

Famous quotes containing the word loose:
“Rain falls for centuries
Soaking the loose rocks in space
Sweet rain, the fire’s out
The black snag glistens in the rain
& the last wisp of smoke floats up”
—Gary Snyder (b. 1930)
