lesion. Later the disease became rather prevalent in the field. In central 
Indiana early blight did not become a serious factor but about Paoli it 
assumed some importance late in the season. August Sth. there were found 
in the fields near Paoli numerous spindling plants which showed a dry 
blackened stem lesion about the stem at and below the ground line. Whether 
or not these plants were the result of using transplants with the elongated 
stem lesions above noted is not known. 
Wilt caused by Fusarium lycopersici caused severe losses to certain grow- 
ers and. seems to be becoming more prevalent in the state. It was unques- 
tionably the most serious disease of greenhouse tomatoes and numerous 
instances of complete or partial crop failure due to this disease were 
found in the Indianapolis region. Owing to the persistence of this disease 
in the soil, its high virulence under greenhouse temperatures, and the ex- 
treme susceptibility of the Bonny Best variety, the greenhouse situation 
is especially deplorable. In the field crop in central Indiana, the wilt 
occurred to a considerable extent locally in areas of various sizes and as 
scattered infected plants in the fields. 
At Frankfort, August 14th., a field was observed in which there was a 
large area of dead plants surrounded by a narrow zone of plants showing 
all stages of Fusarium infection. An experimental field near Frankfort 
was planted with seed from a large number of varieties and singie plant 
selections, one to each row. There were scattered plants in this field killed 
by wilt, a few rather definite areas of wilt, and a single striking case of 
one row, a single plant strain, showing practically 100% wilt. In a 100- 
acre field of tomatoes near Indianapolis no wilt was found and the Paoli 
region was practically free from the disease. Quite likely this disease, like 
the Fusarium root diseases of cabbage and celery, is disseminated by 
means of diseased transplants. 
Leaf mold caused by Cladosporium fulvum was exceedingly serious in 
many greenhouses, the infection being so general in some instances as to 
‘ause the death of the plants. The disease was at its height during the 
ripening period of the summer crop and was favored by the high temper- 
ature and humidity existing in the houses at that time. Leaf mold 
appeared in epidemic form in the fall greenhouse crop at Lafayette and 
Terre Haute. Bordeaux spray and sulphur dust seem to be ineffective as 
control measures and a lime sulphur spray has been recommended. The 
disease was found to a limited extent late in the fall in an experimental field 
at Frankfort. 
A bacterial spot disease previously reported from Michigan! as “canker” 
was widespread and abundant in central Indiana late in the season. This 
disease is characterized by conspicuous black lesions on the fruit and by 
rather inconspicuous black lesions on the leaves, petioles and stems. The 
black fruit lesions are very objectionable from the canner’s point of view 
and the disease assumed considerable economic importance this year. 
Buckeye rot of the fruit caused by Phytophthora terrestria was found 
in one greenhouse near Indianapolis, Only the lower fruits in certain areas 
were affected.
