FUNGI AFFECTING THE CHERRY 



The Brown Rot 



Monilia fructigena 



As stated on page 56, where this disease is discussed 



in its relations to the plum, 

 it frequently attacks cher- 

 ries, as well as jDlums and 

 peaches. Its life-history on 

 the cherry does not differ 

 materially from that on the 

 ]3lum, although it usually 

 does not pass from fruit to 

 fruit so often on the cherry, 

 because the individual fruits 

 do not touch each other so 

 much. Fig. 35 represents a 

 sound ripe cherry, together 

 with one mummiiied by this 

 disease.

The Black Knot 



Plowrightia morhosa 

 This disease is often as destructive to cherries as to 

 plums, under which it has already been discussed 

 Qop. 53-55). The account of its life-history and the 

 means of exterminating it there given applies with equal 

 force when it affects the present fruit. 



The fungus which causes plum leaf-blight also 

 attacks the cherry, and frequently does great injury.
