AREA OF STATE WHERE INFORMATION IS APPLICABLE
South Texas grain sorghum producers will find this information to
be most beneficial because the diseases for which ratings are given
occur on a rather predictable basis. The information is just as reli-
able for producers in other parts of the state where these diseases
represent a limiting production factor.
HOW DISEASE RATING INFORMATION SHOULD BE USED
Disease resistance is only one of many characteristics to consider
in selecting a grain sorghum hybrid. Yield potential in the local area
is the first and most important consideration. County Extension agent
demonstrations are a good source of information on yield performance of
adapted hybrids. Seed companies also have yield information on hybrids
in a given area. Give strong consideration to disease ratings when one
of these diseases represents a limiting production factor.
EXPLANATION OF RATINGS
Resistant - Resistant hybrids should experience little damage
from the disease organisms considered. Only slight infection
by the fungi that cause downy mildew or head smut is to be
expected when these organisms are present.
Moderately Resistant - Hybrids showing this designation for a
particular disease can be expected to experience some disease
development and some loss if the p~tential for disease is high.
Little damage should be expected when the disease potential is
moderate to low.
Moderately Susceptible - Hybrids in this range may experience
yield loss where the potential for disease is high. Further-
more, growing hybrids of this class in areas of high disease
incidence may cause organism populations to build up in soils
where the crop is grown.
Susceptible - Susceptible hybrids should be grown only in areas
where the potential for disease development is low or absent.
If used in areas of high disease potential, substantial losses
may occur.

A BRIEF DESCRIPTION OF DISEASES FOR
WHICH DISEASE RATINGS ARE GIVEN
Downy Mi ldew
Downy mildew has been most severe in South Texas producing areas,
but it does occur to some extent in most areas. It is caused by a soil
borne fungus that can persist in the soil for several years. When sus-
ceptible hybrids are grown in the presence of the fungus, they may cause
the soil spore populations to build up to extremely high levels.
Systemically infected plants have striped leaves with white-to-light
green bands. A downy type growth can be seen on the lower leaf surface
which is further indication of the disease. Plants infected systemically
are destined to be sterile and will not produce heads. Later these plants
will have shredded leaves as though they had been hit by hail. Spores
are liberated from these shredded leaves and fall to the soil.
Growers who have this disease occurring in their field should strongly
consider using resistant hybrids. This will help avoid yield loss and
prevent excessive buildup of the fungal spores in the soil. No indica-
tion of new races attacking resistant varieties of the fungus has ever
been found.
Head Smut
Head smut is caused by a soil borne fungus that infects young seed-
ling plants very early in life. The fungus grows systemically in the
tissues, and the plant appears normal until the smut structure develops
at heading time. The smut observed actually consists of thousands of
tiny fungus spores that fall to the soil where they overwinter.
The head smut fungus is capable of changing and developing new races.
This has caused problems whereby apparently resistant hybrids become
infected. Ratings were made where the old race (race 3) was predominant,
but the new race (race 4) did occur. Ratings shown are considered reliable
where race 3 occurs, but may run somewhat higher where a high potential
for race 4 exists.
Growers who experience problems with head smut should certainly
utilize resistant hybrids. Those who experience infection levels of more
than five percent on previously resistant hybrids are likely to be deal-
ing with a new race of the fungus. Consult test results from areas where
the new races occur for information on the most resistant hybrids.
