INFORMATION ON TREATING GLADIOLUS BULBLETS IN HOT WATER

R. 0. Magie
Gulf Coast Experiment Station
Bradenton, Florida


Why treat? The hot water treatment of bulblets is the best control we have
for 3 of the major diseases of gladiolus: Fusarium,,Curvularia, and Stro*
matinia. There is no other way to obtain disease-free planting stock of
commercial varieties and to keep the soil "clean" for continual use.

What varieties? Never treat new or untried varieties until a test treatment
of a small sample shows that the variety will tolerate the hot water. To
date, all varieties tested have been successfully treated in hot water.
Some varieties were killed when first tested because certain factors were
not understood.

What bulblets to treat: Bulblets should be taken from the best stocks which are
free of virus troubles and free of mixed varieties; dug in warm weather;
and held in shed 2 to 3 months. If outdoor temperature goes below 70 F,
place bulblets in room held at 75-800 F until time for the hot-water treat-
ment. Bulblets from heavily fertilized soil or from muck soils may be killed
by the hot water. Never treat bulblets held in cold storage, even for a
few days. Sort bulblets into large, medium, and small sizes and give durable
labels. Bulblets of size 6 or larger should not be treated unless a small
test indicates that they are heat-tolerant.

How to treat: Soak bulblets in water for two days. Discard floaters. Place
the "sinkers" in partly filled mesh bags. Soak for 30 minutes in continuously
agitated water held closely to the following temperatures: large bulblets
135-136 F; medium 136-137; and small 137-138. Cool bulblets immediately
in running water. Place in shallow layers in sterilized trays to dry and
then place in cold storage.

Pre-planting dip: Bulblets may be recontaminated by dust and develop disease
after planting. Therefore treat all bulblets for 5 to 15 minutes in 3 pints
Elcide per 100 gal. water a few days before planting.

When to plant: The larger bulblets of many varieties which were hot-water treated
in August may be planted in October or November. Small bulblets and late-
treated bulblets may be held in cold storage for spring planting. If bulb-
lets have been in cold storage less than 3 or 4 months, test their germin-
ation before planting. About one month before desired planting date, put
samples in slightly moist sand in glass jars and hold at room temperature
in shade. If five percent or more sprout in 2 to 3 weeks, the-bulblets of
most commercial varieties will be ready to plant. :'

Where to plant: Plant bulblets on new or "clean" soil where gladiolus have not
been grown, or treat soil with chemicals or steam to control soil-borne'-
fungi.
