Symptoms 



The fruit begins to decay prematurely, and 

 small grey heaps of fungus spores arranged 

 in " fairy rings " occur on the decaying spot. 

 Attack generally begins at a wound made 

 by an insect. The apple finally becomes a 

 " mummy," and remains hanging on the tree 

 through winter. The shoots and flowers are 

 also attacked. Brown rot caused by Sclerotinia 

 fructigena {Monilia fructigena). Destroy 

 affected fruit by fire ; prune and spray as for 

 " scab." 



Small brown circular spots on fruit at first 

 minute, gradually but slowly enlarging ; at 

 first only skin deep. Probably caused by a 

 fungus ; no remedial measure known. 

 Ababis. 



White shining swollen convex patches on 

 the leaves as though sprinkled with whitewash 

 brush. White rust caused by Cystopus can- 



Powdery greyish - white patches, on pale 

 finally dead brown spots. Rot mould caused 

 by Peronospora parasitica. 



Spraying is hardly called for with this plant, 

 but affected foliage should be removed and 

 burned to destroy the resting spores of these 

 two disfiguring fungi.
