corms, in quick drying of comns after harvest, in retation of fields, 
and particularly in replacement. of stock from more favored areas. 
Nearly 200 million corms of the variety Picardy have been shipped 
into Florida since 194k, mainly to replace rotted corms. In spite 
of using the best available control measures, growers may lose 5 to 
LO percent of susceptible varieties, Fusarium rot causes the greatest 
loss in warm soils; it is outranked bv dry rot and botrytis in cooler 
areas. 
Botrytis blight affects all parts of the gladiolus plant, causing 
savere damage in cool, moist weather. It causes corm rot in the 
Northern States when wet weather is encountered at harvesttime, a 
transit rot of flowers shinped from the Southern States, and damaging 
leaf spot and leaf rot in all growing areas during wet weather. The 
funzus is carried in the corms, and is capable of persisting in soil 
for years. Corm infection is minimized by curing the corms at 
&5°..95°9 F, aftar harvest. Infections in growing plants are prevented 
with fair success by spraying with zineb or nabam. 
Curvularia blight first appeared on gladiolus in Florida and 
Alabama in 1947. it has since bssome general over the United States, 
and damaging in warm, moist weather, The fungus is carried in corms 
and persists in ssil. Leaves and flowers are blighted; losses are 
most severe in young stock from seed or from cormels. Frequent 
spraying with nabam or zineb gives contrels: rotation of ereps also 
reduces infection. 
Fusarium corm ret occurs in the field and in storage wherever 
gladiclus are grown, caising heavy losses in warm soils in spite of 
tne best available control measures. The fungus is corm-bornme and 
persists in soils for years. Sorting and chemical treatment of 
corms, rotation of crops, and use of planting stock from more favored 
areas are practiced to hold fusarium in check. 
rot of gladiolus corms, associated with neck rot in plants in 
the field, is second only to botrytis blight in cool, moist climates. 
Losses can be kept down by sorting and fungicidal treatment of corms, 
quick curing of the corms at 85°-95° F. after harvest, and rotation 
of crops. 
Lilies 
Domestic production of Easter lilies is concentrated in the South 
east, where bulbs are produced for greenhouse finishing as cut 
blooms during the winter months, and in the Northwest, where bulbs 
are supplied for greenhouse finishing as Easter pot plants. 
In the Southeast necrotic fleck, a virus complex transmitted by 
aphids, has sharply limited production. The disease is not recog- 
nizable in the bulbs, and has been widely distributed in planting 
stock. Fleck-diseased plants are unsalable. The industry survives 
by controlling aphids as well as possible, amd by frequent replace-
