PRESS BULLBTIN 217 Novembedr 29, 1913



With the beginning of the rainy season in June, the grower of citrus
should see to it that he has plenty of the parasitic fungi, both the red and the
brown, in his grove. If they are not already present, he should spare no
pains to introduce them. However, in June fungus material is often scarce,
while now it is usually abundant, and should be collected. Dr. Berger has
shown that it keeps well in cold storage. The grower having cold storage
facilities should now lay in a supply of fungus for use next summer. For this
purpose, collect a quantity of the leaves, and allow them to dry for a day or
two in an airy room, out of the rain and direct sunlight. Then put the dry
leaves in a tight tin box. Place it in a cold storage room where the tempera-
ture is usually below 40 degrees F., or in a refrigerator. Next June, this
fungus material will be fund to be fresh and bright and capable of germin-
But many growers do not have cold-storage facilities. They will .be in-
terested to learn that experiments carried on by this department last winter
and summer demonstrated that, at least under some circumstances, this fun-
gus material may be dried and kept in a dry condition without losing its
power to germinate. Leaves of the red fungus were collected in December,
1912, allowed to dry thoroughly in the air, piled loosely in an open box and
kept in a dry room until July. They were then used to spray trees in the
usual manner. Trees sprayed with this material developed fully as good a
satch of fungus as those sprayed with fungus material which had been kept
in cold storage.
