Ergot was noted on volunteer rye. Stem rust was found in one held in 

 Lagrange coiiuty by R. J. Hosnier. Six si)ecinu'ns of a head snnit ( I'stilago 

 sp. ) were found by Jackson in one held in Porter county. 



Bacterial blight caused by Bacterium fjlycinctdii was prevalent in holds 

 near Lafayette. Leaf infection was very heavy but i)od infection was not 

 as abundant. 



An unmistakable mosaic disease occurred on a small percentage of the 

 plants in one field. The leaves showed typical mosaic symptoms, the pods 

 were fewer and smaller, and very few seeds were produced. In fact mosaic 

 plants were prac-tically a total loss so far as seed production was concerned. 

 There were several rows of garden beans along one side of this field 

 which were severely atfected with mosaic and it is possible, of course, that 

 the disease may have crossed over to the soybeans from the garden beans. 



The non-parasitic yellows or blight which is so severe in the truck region 

 near Norfolk. Va.. was found near (Jo-licn in Octobci-. Tyi)ical stunting 

 of the itlants and yellowing of the leaves were jirodnced. 



SQUASH. 



Bacterial wilt was noted near I>afa.vette. 



STRAWBERRY. 



Leaf-spot caused by Miivosphacrella fragariac was of general occurrence.
