260 SUCCESSFUL FRUIT CULTURE 



FUNGOUS PESTS ATTACKING THE QUINCE 



Black Rot (Sphaeropsis malorum] Previously de- 

 scribed under the apple. 



Fire Blight (Bacillus amylovorus) This disease, 

 previously described under the apple, rarely attacks 

 more than the twigs of end shoots, sometimes destroying 

 all of the fruit, but I know of no instance where the 

 whole tree has been destroyed, or even permanently 

 injured. 



Remedy Cutting off the diseased shoots and keep- 

 ing the trees in a healthy condition are the only pre- 

 ventive measures thus far known. 



Leaf Blight (Entomosporium maculatum) The 

 leaf blight of the pear is often as destructive to this 

 fruit. See under the pear. 



Quince Rust (Roestelia aurantiaca) This rust is 

 similar in growth and appearance to the cedar apple 

 fungus described under the apple. It attacks the fruit 

 and also the branches, and when in the fruiting stage 

 gives the parts attacked a golden yellow color. T)ur'> 

 the fall and winter the injured parts are black.

Brown Rot (Monilia fructigena] See under the 

 plum.

 the plum.
