ANTHRACN/OSE OF THE MANGO IN FLORIDA. 15 
blooming time, though spraying has served to keep the panicles and 
fruits free from infection. 
It appears that while total failures may sometimes occur, more 
often the weather conditions will be such as to favor good settings of 
fruit. 
It is probably never so dry but that spraying will have to be 
resorted to in order to keep the fruits free from disease after they 
have set, and no amount of fertilization or soil medication will take 
its place. 
The production of good crops of mangos in Florida and throughout 
tropical and subtropical zones generally is very definitely related 
to the weather conditions at blooming time. Large crops can not be 
expected when the weather at this time is moist and showery. This 
may be due to some extent to imperfect pollination, but the trouble 
is chiefly caused in Florida by the anthracnose fungus (Colletotri- 
chum gloeos porioides) .
