NOTES ON PLANT DISEASES INTERCEPTED 
Interceptions of plant diseases continued to include many that are of consider- 
able economic importance. However, interceptions of citrus canker {Bacterium 
ciiri) dropped to 4 for the year, white pine blister rust (Cronartium ribicola) was 
intercepted once, and citrus black spot (Phoma citricarpo) was intercepted 3 times 
only, but lima bean scab (Elsinoe phaseoli) was intercepted 360 times. 
Little or nothing is known regarding the economic importance of many of the 
more interesting interceptions. Attention is called to some of the diseases found 
in each of several groups, the pathogens being arranged alphabetically for con- 
venient reference use. 
BACTERIAL DISEASES 
Citrus canker (Bacterium citri) was intercepted on lime from Java and Straits 
Settlements, on grapefruit from India, and on orange, origin unknown, in 
baggage from Canada. Aplanobacter michiganense and Bacterium vesicatorivm 
continued to occur on peppers and tomatoes from Mexico. Fire blight (Bacillus 
arnylovorus) was found on Pyrus from Japan, Bacterium savastanoi on olive from 
Portugal, and several other bacterial diseases more or less common in this country 
were found at times. It should be borne in mind that no provision is made for 
the routine determination of bacterial diseases.
