BLUE MOLD CONTROL IN SHADE TOBACCO
by Randall R. Kincaid
Plant Pathologist

Beds
Blue mold control obtained in plant beds by dusting is quite satisfactory.
Dust beds three times a week with 6.5% zineb, at rates ranging from 15 pounds per
acre at each application when the plants are small, to 35 pounds per acre when the
plants are large enough for transplanting.

Dust containing 3.5% maneb gives better blue mold control than 6.5% zineb. Maneb
dust may be tried in beds if rates of application are carefully regulated as given
above.

Note: Applications of insecticide alone or in combination with fungicide
should be made only once a week, beginning three weeks before transplanting.

Growers of flue-cured tobacco should consult their county agents for current
recommendations.


Shades
Blue mold caused considerable damage to shades in 1957, and growers should take
all necessary precautions to keep damage to a minimum in 1958.

Growers are urged to continue dusting beds until transplanting is complete, and
then destroy remaining plants immediately. This is recommended to prevent the spread
of blue mold from beds to fields. The cooperation of flue-cured tobacco growers as
well as shade growers is needed to make this practice most effective.

Dusting shades twice a week with 6.5% zineb, as commonly practiced, is
recommended again for 1958. Limited trials with 3.5% maneb in shades are suggested.

Some shades or portions of shades, where air drainage or water drainage is poor
and the crop is most subject to blue mold, should perhaps be abandoned, if other areas
are available for shade.

Breeding for blue mold resistance is in progress. Whenever resistance
available in combination with good yield and quality, new varieties wile
to growers.
