Wheat Diseases and Pests - Wheat Doctor - CIMMYT

Development: Initial infections tend to be on the
lower leaves, progressing to the upper leaves and
spikes if environmental conditions remain
favorable. Cool temperatures (lo 0 -1 5OC) and
prolonged wet, cloudy weather favors the
development of these diseases.
HostsIDistribution: These are primarily diseases of
wheat, but other cereals are somewhat
susceptible. The diseases are limited to temperate
wheat-growing areas where cool and moist
conditions prevail.
Importance: Major losses can occur, through seed
shrivelling and lower test weights, if these
diseases reach severe levels prior to harvest.
