The Fusarium wilt is a very serious problem for the florists of the state 
and is of rather general occurrence. 
BARLEY. 
Bacterial blight caused by Bacteriwm translucens was noted May 26 
near Lafayette. Helminthosporium teres, H. gramineum, H. sativum and 
Rhynchosporium secalis were noted near Lafayette by Dr. A. G. Johnson 
June 10. 
Loose smut (Ustilago nuda) was reported by F. J. Pipal as severe in 
some fields. Stem rust was found in one field in Lake county. 
BEAN. 
Bacterial blight caused by Pseudomonas phaseoli was the most serious 
disease of this crop and was exceptionally severe this year both on foliage 
and pods. It was prevalent in the Indianapolis market gardens and was 
also noted near Kokomo, Wanatah, Plymouth, Hammond and Campbells- 
burg. Blight also was found severe on the foliage and pods of a row of 
Lima beans adjacent to a row of badly blighted kidney beans. 
Mosaic was generally present in most gardens observed; but not as a rule 
on a high percentage of the plants until late in the season. 
Root rot due to a Fusarium species was noted early in the season causing 
the death of scattered plants in market gardens. Rust (Uromyces appen- 
diculatus) was found in fields near Plymouth and Wanatah. No anthrac- 
nose was noted. 
Leaf-spot of Lima bean due to Phyllosticta phaseolina was very prev- 
alent and destructive in gardens near Indianapolis and Lafayette.

Leaf-spot caused by Cercospora beticola was not at all common this year 
and was noted only at Goshen late in the fall. A crown rot caused by 
Rhizoctonia invasion through growth cracks and broken leaf bases was 
found in the sugar beet crop about Hammond. 
Nematode root-knot caused by Heterodera radicicola was found in muck 
soil near Goshen and badly affected plants were stunted and worthless. 
An area of several acres in the celery marsh near that city has been in-

six years,
