Forty-eight per cent. of inoculated maize were infected and produced 
spots which resembled very much the spots formed by the maize Helminthos- 
portum on maize. It appears that maize Helminthosporium and jowar 
Helminthosporium are the same, but with slight differences in cultural 
characters and in the form of spores.

Forty per cent. of inoculated sugarcane leaves were infected. The spots 
formed were small, oval and, later on, dirty brown with brownish rings. They 
gradually increase in size, more in the longitudinal direction, and produce 
conidia and conidiophores which have normal character.
