Puccinia pruni Pers. 1'luiu or Prune llust. [This i- ,, 

 common species in both Europe and the United States; it 

 attacks almo>t every kind of cultivated drupaceous fruit, indud- 

 in- prune, plum, peach, nectarine, apricot, chen-y, and almond. 

 The uredospores are brown, the teleut"-pore< darker, and l>otli 

 are as a rule found only on the under surface of the leaf 

 ( Ki'j. 82). The leaves first show yello\vi>h or reddish spots 

 which rapidly enlarge and darken in colour till rupture of the 

 epidermis takes place, and they rapidly dry up. The fruit is 

 thus altogether lost or much injured, while ripening of the woud 

 is more or less interfered with. 



The remedies surest ed are: sprayings with modified can 

 celeste, or ammoniacal copper carbonate (see p. GO)]. 1 (Edit.)
