THE CHERRY 93 



May beetle : This well-known "June bug " some-

PRINCIPAL, FUNGOUS PESTS. Black knot : Dark, 

 knotty, wart-like bunches upon twigs and branches. 

 Hasily seen and recognized. Spreads if not promptly 

 attended to. Remedy : Cut out and burn all knots as 

 soon as seen ; cut well below the diseased parts (also, 

 spray the trees with Bordeaux) .

 the fruit, quickly ruining it and rapidly spreading to 

 adjacent cherries ; infected specimens may drop to 

 the ground, or they may shrivel up and stay on the 

 tree all winter, thus carrying the disease to next

 and burn all mummied cherries found on the trees in 

 the fall ; spray with Bordeaux, several times, early in 

 the season ; pick the fruit promptly and early. 



Leaf -blight or spot : Often called the ' ' shot-hole 

 fungus." Makes round spots on the leaves, which

Powdery mildew : See Chapter X.

 has set, using same mixture ; two weeks later,
