On the branches the spots are at first reddish, becoming slightly 

 sunken with a central elevation and blackish in colour in the 

 coalesce, sometimes encircling the branch, in which case the portion 

 above the diseased area dies. 



The fruit of pears is sometimes spotted by the disease. 

 Bordeaux Mixture keeps the blight in check. 



SCAB. 



PEACH FRECKLE causes dark spots on the skin of maturing 

 fruit, which present a freckled look. These spots are the result of 

 the attack of fungi, and amongst them the Cladosporium carpophihcm . 

 Its filaments do not enter the peach, but draw their nourishment 

 through the skin. It is said that the disease hastens decay, and 

 that affected fruit will not stand long keeping. An early applica- 

 tion of Bordeaux Mixture stops its progress. Potassium sulphide, 

 half ounce to the gallon, is also recommended. 



Scab and Peach Freckle. 



ROOT KNOT often shows on peaohes, plums, etc. It is 

 caused by a fungus called slime mould, related to the one which 

 causes the finger and toe disease of beetroot, carrots, etc. 



Pare out the excrescences and wash with an antiseptic lotion. 

 If it is a young tree and is badly affected, replace by a healthy one. 



SHOT HOLE DISEASE (Phyllosticta circumcissa) attacks the 

 leaves of apricots, almond, peach, nectarine, and other stone fruit 

 trees. Appears as spots upon the leaves in summer, and these spots 

 assume definite outlines, and often fall out, leaving holes like shot- 

 holes. The leaves fall early, preventing the fruit from maturing. 

 These are also attacked, and at times disfigured.
