Sixty-nine per cent. of wheat plants were infected when inoculated. The 
fungus penetrated and at the point of infection the leaves withered and broke. 
There was spore formation on both sides of leaves.

Jowar Helminthosporium can infect barley leaves but the infection is not 
vigorous. The spots formed stop growing after sometime and spore formation 
is not plentiful.

As in the case of barley, on oats also infection is not vigorous and the 
fungus stops growing in the tissue after some time. 
These experiments show that jowar Helminthosporium can infect— 
Jowar 79% Maize 48% Sugarcane 40% 
Wheat 69% Oats 41% Barley 37% 
Rice 13% Bajra 0% 
From the above figures it will appear that about 50 per cent or more 
infection takes place on wheat and maize, and in the case of sugarcane, oats
