Information on Treating Gladiolus Bulblets in Hot Water

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


Why treat? The hot water treatment of bulbletsis the best control we have
for 3 of the major diseases of gladiolus: Fusarium, Curvularia and Stem-
phylium. 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 treatment of a
small sample shows that the variety will tolerate the hot water. Some
varieties including Hopman's Glory and Florida Pink are killed by the
treatment.

What bulblets to treat. Bulblets should be taken from theibest stock which
is free of virus troubles and free of mixed varieties;'dug in warm wea-
ther; held in shed 2 to 3 months. Bulblets from heavily fertilized soil
or from muck soils may be killed by the hot water. Never treat bulblets
held in cold storage. Sort bulblets into large, medium, small and "pin-
head" sizes and give durable labels.

How to treat. Soak bulblets ih cool water for two days, Discard floaters.
Place the "sinkers" in mesh bags or boxes with sides of window screen-
ing material. Soak for 30 minutes in continuously agitated water held
closely to the following temperatures: large bulblets 135-136 F; medium
136a1370; small i3741l89 and.pinheads 13~139. Cool bulbe'ts immediately
in tuning water Keep Lhem frbm contact with sbil, floor and tables or
trays previously used for gladiolus. Place in shallio0 layers in hot-
water treated or chemically sterilized trays to dry and then place in
cold storage. Avoid contamination from dust at all times.

Bulblets may be planted without further treatment except to soak
in clean water. Bulblets treated at 135-136 F and those contaminated
by dust were improved by soaking 1 hour in 1 1/2 pints Elcide 73 per
100 gal. one day before planting.

When to plant. The large bulblets of many varieties which were hot-water
treated in July can be planted in October or November. Small bulblets
and late-treated bulblets may be held in cold storage for spring plant-
ing in other states or may be planted the following fall in Florida.
If bulblets have been in cold storage less than 3 or 4 months, test
their germination before planting. About one month before desired plant-
ing 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-are ready to. plflt"^c' .

Future planting stocks should be obtained from the smallest bulblee created
at 138-1390 F and grown in '"clean" soil. DE'
