ized on both the leaves and fruit by dai-k-colored or olivaceous 

 spots, giving, as the name indicates, a scabby appearance to 

 the frnit and leaves. 



Treatment with lime and sulphur in the spring, in the dor- 

 mant period, according to our observations, holds the fungus 

 in check. Other fungicides also control it. 



Pink Mold or Pink Rot (Cephalothecium roseum Cda.). 



Since 1902 a pink mold has been known to be associated 

 with apple scab, although it has caused little or no trouble in 

 this region. As the name implies, it is of a pinkish color 

 and is confined to the scabby spots on the fruit, developing 

 over the surface of the scab. Although the fungus has been 

 present for some time in this region on dead wood, etc., it 

 was supposed to be perfectly harmless until 1902, when it 

 was discovered as an accompaniment of the scab. It causes 

 much more injury elsewhere than here, and is more severe in 

 moist seasons. 



Any treatment which will control the scab is applicable 

 to this mold. 



Leaf Blight (Sphteropsis Malorum Pk.). 



It is generally believed at the present time, from the re- 

 sults of experiments, that the above-named fungus is the 

 cause of the so-called leaf spots of the apple, although they 

 were formerly attributed to other fungi, known as Phyllos- 

 ticta Pyrina Sacc. and P. limitata Pk. These two species 

 of Phyllosticta are now considered merely accompaniments 

 of the leaf spot, occurring only in the later stages of the 

 disease. The foliage of most neglected apple trees develops 

 these spots, and the disease is sometimes severe enough to 

 affect the gi'owth of the tree. The fungi associated with 

 the leaf spots, however, are easily controlled by spraying 

 with lime and sulphur in the spring before the buds open, 

 and therefore are of minor importance in well-cared-for 

 orchards. Many orchards go through the season without 

 a spot as a result of spraying with lime and sulphur in the 

 dormant period of the tree.
