NOTES ON PLANT DISEASES INTERCEPTED 
Among the plant diseases intercepted during thp. fiscal year 1938 v^ere several 
well knovv'n as being serious on iuiportant economdc hosts. Am.ong the diseases 
were citrus canker (Bacterium cilri), banana leaf spot (Cercospora musae), cereal 
rusts and smuts, and citrus black spot (Phoma citricarpa). Other diseases were 
intercepted which might prove to be important i^ introduced but which were 
caused by new species or were on unreported hosts and their economic status not 
determinable. 
For convenience some of the more interesting pUint disease interception records 
are summnrized by groups in alphabetical arrangements. 
BACTERIAL DISEASES 
Citrus canker (BacLcrivm citric was intercepted on lemon from Straits Settle- 
ments, on lime from Egypt (2), the Philippines, and Straits Settlements, on 
orange from China (3) and Japan (9), on pomelo from China and Straits Settle-

during the year, in a hyacinth bulb from Xetlierlands. Pumpkins from Japan and 
Straits Settlements were found with bacterial spots such as are produced by B. 
lacfiryn-i'ins on other cucurbits. 
We have no adequate facilities a\ailable for the determination of bacterial 
diseases, lience many bacterial infections are not determined,
