SCLEROTINIA DRY ROT is common and in wet seasons may increase 
to serious proportions. Both a field and storage problem and is most 
prevalent in heavy soils. Rapid and thorough curing of the corms after 
harvest will prevent development in storage. Rotation, sanitation and 
chemical corm treatments are other controls. 
BOTRYTIS infected corms should never be planted. Where suspicious, 
treat the corms as recommended for control of other corm-borne organisms. 
Corm treatments, in conjunction with crop rotation, usually provide effec- 
tive control of SCAB. Likewise, BACTERIAL BLIGHT. Roguing is best 
to reduce VIRUS DISEASES, the insect vector still being searched for. 
Corm treatments also are a benefit in control of INK SPOT. 
FUSARIUM DRY ROT causes a brown dry rot of the corm the same as 
fusarium yellows, other than that they differ. Picardy and it’s progeny are 
very susceptible to dry rot while resistant to yellows. A pre-planting dip 
with Ceresan has been standard, together with other cultural and sanitary 
practices. PENICILLIUM DRY ROT is controlled by rapid drying after 
harvest and good storage conditions. We recommend ARASAN dusting 
before storing. 
One of the best treatments that may be applied to the dormant corms 
after cleaning them, to help prevent the rotting that occurs between the 
time of digging and planting is DUPONT’S ARASAN, 30 parts, parzate 
10 parts, and 5% DDT 60 parts by weight. 
PRE-PLANTING TREATMENTS. New Improved CERESAN at the rate 
of 1 pound for 50 gallons of water with a fifteen minute dip is standard. 
Add a little Dreft as wetting agent. Four pounds DUPONT’S TERSAN 
in 50 gallons of water plus wetting agent, stir while treating for five 
minutes—is especially recommended for BOTRYTIS control. One half 
teaspoon of DUPONT’S ARASAN dust will treat a hundred bulbs. 
ARASAN SF a little stronger product, of the same, that goes into solution. 
ARASAN is not poisonous.
