. The most heavily infes- ted large area in Louisiana, and consequently in the Uiiited States, is between Hutcher and Reserve, where about 75% of the plants on every planta- tion were infected. The amount ranged from 4-30% from this district to New Orleans and from New Orleans to the lower extremity. In the Payou- Lafourche district 1-8% of the plants were infected. In the vicinity of Cairo, Georgia (Grady County) the infection ranged from less than 1% to 75%» more, in fields where the disease was present.

Purely local infections were found at Apalachicola, Tallahassee, Punta Gorda, Palmetto, De Land, Winterhaven, Chattahoochee, Ivluscogee and Canal Point. In Alabama it was found at only one place, that in Baldwin County just over the line from Muscogee, Florida. In Mississippi, it was found at Biloxi, the only point in the state. The loss in Georgia was from 1-5%. In Louisiana the loss was considerable. Resistant strains in Georgia and Florida were the Japanese varieties, while the green chewing corn was the most susceptible. In Louisiana in the test plots at Audubon Park, New Orleans the head seedlings 1646, I606, 1G74 ^nd I757 appeared to be immune. The varieties which are corrmon in the state and which proved to be very susceptible were Louisiana Purple, Louisiana Striped, j74, D95, L5II, L2l8, L219, L22G, L23I and L253.
