LILIES FOR GARDEN AND GREENHOUSE 
disease mentioned is a fungoid condition caused by Botrytis elliptica. It can be 
identified by the appearance of watery, brownish spots on the foliage which if 
allowed to go uncared for will spread rapidly over the plant and to other lilies in 
the proximity. To prevent the occurrence of the disease is of course most desirable 
and to this end we advise spraying of the plants with ''Sulreso" followed by a 
dusting with "Bordusto", a bordeaux dust. This should be done every week to 
ten days from the time the spikes appear above the ground in the spring until dry, 
settled weather is assured. It is particularly essential that the spray and dust be 
applied after heavy rains which would wash off the previous application. 
The spread of Botrytis is checked by high temperatures and dry weather, 
hence it is not necessary to continue the treatment during mid-summer when mean 
temperatures rise above 65-70 degrees F. The conditions most agreeable to its 
spread are the rainy spring days and nights when the thermometer reads between 
55 and 65 degrees F. and it is at this period that proper attention to prevention or 
control should be given. The ''Sulreso'’ spray is used to coat the plant so that the 
spores of Botrytis are unable to germinate. The "Bordusto" dust prevents re-infec¬ 
tion from outside sources. The proper application of the spray and dust is im¬ 
portant. Apply the spray with the best pressure equipment you have available 
so that the entire plant, leaves, stem, and buds, if any, are thoroughly coated. 
Before the spray has dried dust carefully with "Bordusto" so that all parts are 
lightly covered. Repeated light dustings are better than infrequent heavy ones. 
The resin in the spray causes the dust to adhere to the plant and this combination 
will protect the foliage for some days even during extremely wet weather. As 
"Sulreso" dries rapidly if applied when the sun is on the plant, proper prepara¬ 
tions should be made to dust promptly for maximum effectiveness. 
If plants are attacked by Botrytis before a first spraying is applied, it is wise to 
remove diseased parts and burn them so that no opportunity will be given for the 
spores to come in contact with the ground where they will live over the winter 
for a fresh attack in the following spring. Likewise all old foliage should be col¬ 
lected and burned in the fall as a further means of prevention. In the case of 
L. Candidum, fall spraying and dusting of the early foliage, which this lily pro¬ 
duces, is advisable. 
"Sulreso" is also effective in the prevention and control of Botrytis on Tulips. 
The application of "Bordusto” to Tulips, however, is not advised. We have like¬ 
wise used Sulreso in combination with Nicotine Sulphate 40% for controlling 
botrytis, aphis, etc., in one application.
