what are the symptoms of Powdery mildew of wheat?
Answer / swapna
symptoms are small, effuse patches (colonies) of cottony
mycelia (masses of fungal threads of hyphae that make up
the body of the fungus). These occur on the upper and lower
surfaces of the leaves. As these patches sporulate and age,
they become a dull tan color. Chlorotic (yellow) patches
may later surround the mildew colonies. As the wheat and
the mildew colonies mature, the sexual stage of the fungus
or cleistothecia are produced. The mildew fungus survives
the summer in the absence of wheat in infested wheat debris
in the cleistothecia.
