Maize Helminthosporium can infect barley but the infection is not so 
vigorous as that on wheat. Out of 45 inoculations, 21 were infected. Spores 
were formed on both sides of the leaves incculated.

Out of 53 inoculations made, 27 were successful. The infected spots 
gradually increased in size and spore formation took place. Sometimes no 
infection took place as on those inoculated on 19th January, 1920. 
The above cross-inoculation experiments show that maize Helminthos- 
porium can infect most of the cereals and sugarcane when inoculated artificially
