In Porto Rico(1) it was found that shading reduced the berry 
loss from 10 to 30 per cent. At the present writing this has 
not become necessary here, however. 
SUMMARY 
1. Leaf spot of coffee, caused by Cercospora coffeicola 
Berkeley and Cooke has been found on nursery stock of the Col- 
lege of Agriculture, Los Bafios, Laguna. 
2. This is known as “brown eye spot,” “brown eyed disease” 
or “berry spot,” described by Butler, by Faucett, and by Cooke. 
3. In the Philippines attack is confined to leaves and there- 
fore it is not very serious. It may spread to berries and become 
more dangerous. 
4, It is found only on Coffea bukobensis. The source of 
the disease is unknown. _ 
5. The causal organism checks with the previously described 
Cercospora coffeicola Berkeley and Cooke. 
6. The disease was controlled by spraying every two weeks 
with Bordeaux mixture.
